Street Stock 250cc 4-stroke twins

[gatch]

I wouldn't even bother torquing about talk on a 250.

End of the day with proddy classes it about who has the biggest dick and balls, not the most torx.

Your buddy ken obviously has reasonable frank and beans..

[sil3nt]

37rwhp on a gpx :lol:

37rwhp on a gpx :lol:

especialy on a practicaly stock one.....but he must of been happy when he beat choas on his 40hp hyosung tho.....:yes:

37rwhp on a gpx :lol:

Lol wtf ! That's almost as much as my vfr ! Maybe I should 'upgrade' to a 250, these new machines must be fast !

Just got in from the Vic club meeting...

the option of letting a 250 twin in with our race program will be....

they are more than welcome to come along and race with the 250's that are already there..
PLEASE go to the MNZ web site for the rules...

pay ya money get a licence and come play at our meetings.

Vic club rule No. 1.

YOU MUST HAVE FUN....!!!!

I've got a stripped down rolling spada chassis in my shed, just noooo motor after it overheated and melted some very expensive and hard to find parts..

Was planning on stuffing the biggest motor I could in it for a laugh, but racing it and smoking hyoslags would be way more fun..

Just a wee bump here


My old spada may be up for sale for the right price. The guy who bought it has got the shits about the cam chain rattle [the tensioners are being gay]
From memory you can bore out the oil feed hole on the tensioner and viola! no rattles. Plus my old one looked the ducks nuts [like a handbag....]

Chaos, a gpx makes more power and torque than the hyosung. Kens bike may handle better even though it will be heavy, but, it's the rider that helps. A gpx will be lucky to push 30rwhp, which is alot more than a hyosungs 24rwhp [on a brilliant day]

Alright,

this is a nice and blatant plug for myself, you may notice that I voted "not sure" in the above poll,

I'm not sure mainly cos I'd never been to a track before, can't really afford...
So if you haven't already, vote for me in the free ART day pass at puke and I'll have my chance to see if it is something I want to pursue.

Kens bike aint heavy, maybe 140kg...., the power on kens bike is realy good, but its not the same as a 150 water cooled two stroke......as its not as exciting, the torque is up there, And for sure id much rather ride a hyosung than a GPX because the hyosung has the right riding position....

It will be interesting to compare my ss150 bike with kens ss250 when i ride my 150 for the first time this weekend.



Its a pity chaos isnt ridng in the TRRS because he'd learn alot from riding with lots of bikes the same power as him.

How did ken get more than 30kg off the standard bike?
Would be interesting to see what a two smoke 150 is like in comparison, I think the two smoker would be quicker.

standard exhaust, dash assembly, lights, indicators, pillion gear,stand......ect i took 10kg worth of weight of my cbr and ive still got lights and standard exhaust.....

Ive taken the krr150 down my street in 3rd.....and man does it pull!!!, the hyosungs power is more slower to come.....but about the same, the 2 smokers just deliver it in an more exciting way.

The ss150 bikes from what ive heard are better top speed wise as they have a 6th gear, On track 2 i was doing 145km/h on the hyosung in 5th....it had plenty of throttle left so a top speed of about 160-165km/h. rg's,kr's,krr's ive been told ss150's would do 180km/h...

The standard exhaust doesn't weigh too much, remember, it's being replaced by a same length or longer system, so onluy a few kg there. Dash cluster weighs as much as my left nipple. Lights don't weigh too much :innocent: Pillion gear is a piece of plastic with foam and two alloy pegs, 3kg max I would expect. Stand really is not very big, so at the end of the day, it would make more difference with my weight vs Chaos. I'm just over 50kg [full bladder and stroked ego] and I hear Chaos is a wee bit more....

But really, the rider counts, Rossi won on the Yamaha because he is amazing....not because he has 5kmh more acceleration and less top speed [wtf?]

I am going to be interested in seeing the lap times between all the v2 four strokes and the 150's :scooter: :woohoo:

[quickbuck]

Yeah, I must have skipped school when my physics teacher taught the class about that....

[woodyracer]

At PMCC round one the fastest ss150 did a 126.823......ken dodson did a 130.895 and hes faster than chaos.....so at the moment ss150 is kicking ass.

[SS90]

The ss150 bikes from what ive heard are better top speed wise as they have a 6th gear,

What the Fuck?

Please explain this to me.

How the hell can having a 6th gear make a bike faster?

[huff3r]

What the Fuck?

Please explain this to me.

How the hell can having a 6th gear make a bike faster?

It can't. All it does is make the ratios in the box closer. Unless of course the 5 gear bikes rev all the way out in 5th, then a 6th gear would help (or change a sprocket ;) but i dont think they're allowed to do that? )

But closer ratios from a 6-speed is always good, i know my racecar could do with an extra cog!

[woodyracer]

What the Fuck?

Please explain this to me.

Its hard to explain to special people. :lol:

[huff3r]

Its hard to explain to special people. :lol:

It's not hard to explain. Seriously, because its wrong. Having an extra gear does not make anything faster.

The Hyosung is slower, not because it is a 5-speed, but because it is slower! Less power/more weight.

[SS90]

Its hard to explain to special people. :lol:

Have a go.

Explain why having a sixth gear would make a bike faster.

I think it is about time we dispelled a few myths (although I think we touched on this subject in the original "birth of a monster" thread... (oh sweet sweet memories);)

ok, because the gears are move divied out, jsut one question,

Why would manufacturers bother "wasting" all that money,time and weight to add a gear that does nothing????

There's obviously a reason for adding a sixth gear, otherwise it wouldnt be on bikes.

An amigious answer if ever I have seen one.

Well, in the interests of not confusing the issue, I will simplify things.

Manufacturers select available gear ratios (and amount of ratios, by that I mean (normally 5 or 6, but Cagiva did make a production 125cc 2 stroke with 7 gears) not solely on cost, but rather on "intended purpose"

Important concept here.

If you have an engine (air cooled v twin 4 stroke, like, say a Hyosung 250) that is designed to be easy to ride, economical and reliable (read LEARNER bike), then things like camshaft profile and cylinder compression, valve size are all set to deliver maximum torque and power in a linear fashion, lower in the rev range.

Therefore, you simply do not need 6 closely spaced gears (like, say a 4 cylinder 250, or even a 250cc two stroke, due to the fact that the power characteristics of the engine allow the power to come in the lower RPM's, and hold a long flat torque curve.

Making the bike easier to ride.

The fact that a 150cc two stroke has 6 six gears does not make it faster.

The reason is that a two stroke delivers a higher BMEP (break mean effective pressure) than a four stroke.

6 gears makes it easier to "keep in the power" (as a two stroke with high exhaust port time areas and coupled with high cylinder blowdown times, as a ss150 is) because the characteristic of such engines is a (very) narrow power band.

That said, there are plenty of 2 stroke tuners that can make similar power to a ss150 with engines that have 4 or 5 gears.

Ergo, 6 gears do not make a bike faster.:calm:

Let's see what this leads on to!

It leads to this :motu: hahahha :lol::lol:

After reading that i guess your right, ive just been looking at it wrong, but at the end of the day the ss150 bikes still have a better top speed.

Thanks for getting rid of my bullshit theories :cool:

-Max

[gatch]

6 gears does not make a bike faster, but funnily enough all the fastest bikes have 6 gears, simply to keep the engine in the rev range where it makes the most power I guess.

Unless a bike is tuned to deliver its power at high rpm (as ss90 said mentioning BMEP) then 6, 5 or even 4 gears may not be necessary..

[sil3nt]

My GPX has 6 gears. Top speed is acheived in 5th. 6th is for cruising.

[chaos rider]

the hyo has the power for a sixth but it would be as nesessery as rossi using nos

[ajturbo]

My GPX has 6 gears. Top speed is acheived in 5th. 6th is for cruising.
very much like the shitter i took for a test ride up in Auckland..

1580cc Vtwin shitter.....
newest shitter out there... and for good measure, it had 6 gears..

well, thinking to myself... with all that cc under me, 6th gear would be fine on the M/W of Auckland.......

FAIL....!!!!!!!!!!!!

it did NOT have the power!!! put it into top and it would SLOW down...it could not hold a steady speed.... so (being a KBer) i thought if i go faster then put it into 6th.. so i tried

120k... FAIL (slowed)
130k....Fail..(slowed)
140k...... hmmm... now it seamed ...Oh..no it slowed...
well i was going to try a bit faster, but there was a corner coming up and as they do not like going around corners (THIS model)... i had to slow (yeah i put it into top... hahahahahahah

but it was a big fail... that extra gear was not worth it (on THIS bike)

[SS90]

My GPX has 6 gears. Top speed is acheived in 5th. 6th is for cruising.

Interesting!

Try this. Either put a larger (3 teeth more) sprocket on the rear, or a smaller (1 tooth smaller) sprocket on the front.

It may well increase the top speed in 6th.

Of course it will increase the revs as well, but that is the idea!

[ducatilover]

SS90 - Nail, head and hammer. I like your example of BMEP, not many buggers know about this :2thumbsup
Chaos, I doubt your bike would push another higher ratio, it has 5 gears already and would struggle to push past peak power in 5th. All the Hyo's I've ridden can't push to the limit of the gearing, because, hyosung compromised with the ratios to make a nice balance between cruising at given speeds and the amount of effort it takes to do so.
Like any 5.7 holden with the 6 speed manual, the 6th was very very over geared for the sake of high speed cruising and feul economy, a VY SV8 would pull 254km/h in 5th gear [redline @ 5500] and when in 6th would be pulling 236km/h at 3400rpm, which was as fast as it would go. [Australian test] :2thumbsup

Keep thrashing the hyo Chaos.

[chaos rider]

i run my hyo past its peak power and into the redline in 5th just as fast as i do in 3rd so i dont see what your on about.

ill not even be half way down the straight at puki and im in 5th climbing 10.5rpm and wanting to shift to 6th BUT I GOT NO 6TH.

so maby hyo have a consistancy issue with their power output with the factry line

ive also riddin other hyos and a few have not got the same pull as mine did.

form what i gather the pre 09 models had lots of consistancy issues beetween the same model line

As fast as third? Don't be silly mate.
10.5krpm in fifth gear? What RPM was it doing at 100? I think from memory it was around 7-8krpm? Show me a video.....their max hp claim was 33hp on the older bikes....That would give a real life 150km/h plus or minus 5km/h

If its got enough pull to rev out in 5th, then an extra gear might give you extra top speed, but it could easily acheive that same higher top speed just by changing sprockets.

The only bonus of a 6th gear is that you would retain the ratios as close as they are now, as sticking with 5 you would be making them slightly longer by changing the sprocket... necessitating less gearchanges, as long as the bike can handle the jump between gears... which a 4-stroke smooth torquey bike like a hyo should manage easy :D

What does a Hyosung & for that matter a Kawasaki ninga EX redline at ,out of interest?
Poor ole Spada commonly sees 14 thou,though peak torque is at about 12...redlines 12500.
Pretty wicked revs man, for a wee 250.

i found on a hyosung the power drops off at 10,000 RMP thats pretty much on the redline,

[sil3nt]

Redline is at 14 on the GPX. Power drops off after 12.

[gatch]

You rev your spada to 14K !! Jeez..

I thought Redline was 13.5k ? I never used to bother going past 12 as the power dropped sharply, when the motor starts going quiet its time too shift up..

[puddytat]

Yeah, I too try to change earlier but sometimes in the heat of racing I hold it up there 'specially if a corners coming up & a gear change aint worth it...
Ruapuna has a pretty long main straight as well & shes fully tapped out at the end of it.
Yore right Gatchy, redline is 13500.
One week to the Port Nelson streetraces...:wait:

The Port races are a really good day out,& the fields are generally pretty full...
"Tards this year will be extra good I reckon 'cause Josh Coppins'll be there on a RMZ 450 it may bring a few extra spectators along.:cool:
Had a wander around the "track" the other day when up in Nelson shopping, they've resealed a few of the corners which look grippy as, compared to the rest of it which is looking a tad worn....
Being the Port though the surface is dirty as fark, what with all the logging trucks & associated detritus everywhere....hopefully there'll be a torrential downpour on about thursday to give it a wash.

Suffice to say that I didnt win Formula 3, that I was on the most gutless bike, I didnt crash & I DIDNT come last:woohoo: Almost as good as a win really.
Awesome event though, & I realy liked the track as you could join the infield corners nicely together & I made up a lot of lost ground from the main straight thru there....
Pretty wild night the night previous camped up under the tarp on the back of the truck as it blew its ring out for most of the night, but I had the good company of a couple of Upper Hutt-ians
:laugh::niceone:
Great atmosphere in the pits & a good crowd turnout once it cleared up...looked quite dodgey with the weather , with wet practice sessions first thing but by showtime the track had dried nicely .

That wet race was a blast, got a 9th out of 40 racing against with pre 89,82,72 senior and junior. GSXR1100's to CB350's. I got a 3rd in pre 82 junior in that race. Had a crap start in the 2nd race and lost 6 places , got 5 of them back but had to ride really hard, had a good 2 lap battle to get past a TZ350, got him on turn 10 on last lap. got 16th overall and 4th pre 82
Bike had a major vibratiion, Main bearing failing on flywheel side. hope to have the new engine ready fort manfeild in 2 weeks, if not i will put my road bike engine in for that meeting

A young fella I know will be out on his Ninja in streetstock at the Nationals this weekend at Ruapuna...so good luck to young Seth!! I dunno if there'll be any other prolights out there for sure, but I had heard there was a couple in the pipeline....
Seth had offered me his 150 to ride at the Nats, seeing how the Spada aint eligible. Wouldve loved to but its busy times with hay making etc...Oooooh well, next year maybe.
Next outing for me'll be the endurance event in March at Ruapuna or Methven street races.

Any seen or heard from Chaos?

ill be seeing him on the 6/7th march

[woodyracer]

So the class is growing big now!, after doing the nationals there was 6 250's.....great stuff

[fizzafulla]

Excuse my ignorance but how is the production light class coming along? I'm not keen to read all 89 pages to find out the slow way.
Is a 250 twin 4 stroke still the way to go to get into racing? Would hate to get one if the class didn't catch on.

Thanks, Dan.

they great mate, its geting along great, they are abit quicker than 150's but they run with them. Theres a few of them poping up, its a great way to get into racing, the bikes i suggest is a kawasaki ex250, or hyosung 250, they the bikes ot get

[fizzafulla]

Good to hear. Those kawis look pretty cool alright. I may have to take the super cheap option of tidying an old twin up are other bikes eligible? I read that a guy's spada isn't eligible, they seem ideal to me.

yea the kawaka's look good, i dont realy like the fell of them for a race-bike because they have a neutral riding position compared to the hyosugns more race-like ridng position

Get a wecked bike, they are cheap,

[puddytat]

The main criteria for what is eligible to race in this class is that it was sold new in N.Z.....Spada's are a Jap only model & so they're a "Grey import".
And that there has to be a minimum of 50 imported new.
Also there a one or 2 other rules like rim width & diameter that also rule out other bikes.
www.mnz.co.nz will have the rules on there.
Depending on what club your with,you may be able to run something in the class thats non-conformist but youll have to ask them.But if its not Kosher then you will not be eligible for the National rounds or points....
Good class though I reckon....its a hoot, & some great close racing with the 150's too

oh that explanes it. Close racing with the 150's isnt it!, although the alot of people are selling their 150's for a 250's........will be a big class come next years nationals

And it's a damned shame too.. A pity they didn't homologate the vtr 250. You could try argue that a spada is the old vtr etc. But I don't know if that woould actually work..

Nice shot on the spada too. Still got plenty of lean on that sucker though. When the fold up pegs are crushing your foot against the frame you're about there :p

It's interesting that the conversation always veers towards eligibilty of models for this class.

I suspect that a few people will be dissapointed because the only bike that can easily afford is an older model "grey import".

I can see their point..... why omit a large group of bikes from competing, when, most likely they won't be any faster than one that does comply with the regulations.

The sad reality is that if they started to have "grey areas" as far as machine eligibilty goes (Jap market stuff), then the skope for "cheating" (although, rule "bending" is really an "unfair advantage" in my book).

The concept that 50 bikes must be imported by the distributor from new is a great idea.

This sort if rule comes from way back in the 70's and 80's when (some) distributors where building a few "specials", and passing them of as homalgomated models, when in fact they where modified machinery (ask your grandfather what a Suzuki "black piper" was)

As far as I am aware, this rule does not disadvantage any one brand more that the other.

If you allowed Japanese market stuff, then the officials would have a hell of a time proving if someone had illegal sized rims, when, perhaps indeed one Japanese model did actually have a wider rear than another model.....where does it all end?

250 production (back in the day) was plagued with RGV wolf gearboxes (close ratio) being fitted to "production machines".....ignitor units being swapped, wider rims, ported cylinders, raised compresson etc etc, and it just became a slippery slope where it came to a point that even if you had all the talent in the world, you still could not win unless you "bent the rules".

I see this set of rules for this class as a real world attempt at reducing this risk, as well as appealing to distributors, and competitors alike.

I would also hasten to add that in reality, if a young guy or girl turned up to race a nationals round on a grey import bike, that, by definition does not comply for championship points, that they would in all likely hood be able to compete in the weekends points race for the class, but, not be a able to take any points away for the meeting.

Despite some of the bad press some officials get, they are all there too see racing flourish.

[gatch]

You're right it is for the best. I'm just saying it's a shame, not that the rules should be changed..

After all, this is proddy racing, if you are going to be racing a stocker, then if you are really keen to win, you'd want to start with the fastest bike you could etc..

[woodyracer]

Theres cheap wrecked hyosungs on tardme...with a new muffler, tires they can win....
Cant wait to debue the '10 EFI at hampton downs next weekend!!

Are you racing your 250 this weekend max?

looking forward to the last round, track 2 is bloody awesome:yes:

What ever happened to Chaos?

[boostin]

Can anyone point me in the direction of what bikes qualify for this class?

So far I seem to be able to work out that there is the new Hyo and Kawasaki 250's, anything else?

yep i did , had a great time..most fun ive ever had on a bike..

last i heard of chaos is he crashed at puke and got pretty smashed.......not suprising

It was a faaaarkn good weekend al right max ;-)

You were riding well and getting faster all the time

I got consistant 1.24s, so close to 1.23...............

Chaos should have gone to taupo instead of armco ridden Puke, not much room for (newbee) error there

Crashed heaps at Taupo and its very safe

I love going up the hill onto the front straight. Passed a few fellas there at the classic festival.

When did chaos crash?

Must have had his lap top with him as well !

He seems to have dissappeared......................

Did he wreck his bike much?

So the VTR`s not able to run in the class? Some say it is, some not,think it`s confusion with VT250.In the rules maybe just state homologated models. That`s what they seem to do in Ozzy, saves confusion. Plus if everyone and club, used the same class name,that would be helpful also.

Rumor has it the Yanks spent $200,000 inventing a pen to write in space,the Russians took a pencil.

Is it my imagination, but this class... formally called Production Lite by MNZ, been swallowed up by the new SuperLite Rules. (http://www.motorcyclingnz.co.nz/download/Proposed_RR_Rules_AppendixH_Superlite.pdf)?
Or is it still seperate?

[Racey Rider]

8) Tyres:

d) Be worn no more than to the minimum tread depth indicators,

I'm not keen on that. To 'some' of us, there's another three race days left in those tyres!

[Howsie]

Wow I cannot believe that this thread still lives! I remembered when this all first started, such drama. I would have loved to raced Chaos, at the time I was still in Novice slow at Puke. Just before I left Auckland I should have been in Novice fast where he was. Ford hill was my favourite corner, passed a few people.

I thought the title of this thread would tell people what bikes they could race in Production Light. Not that I am really up with the play much either.

Sad to hear that the mighty Hyosung had an oopsie. Hope Chaos is ok, not a bad fella once you got to know him, just really opinionated. Side blinkers too closed.

[quickbuck]

Wow I cannot believe that this thread still lives!

Yup, still alive....
Are you doing any of the VMCC Rounds?

I think it is for the safety factor.... Like RAIN.
To be honest, tyres are cheap. Crashing isn't....

Id very much like to and i will be, iv been busy socialising in other circles of late to get out on the bike much for rides. Am planning on joining up as the Auckland club was cool but Im sure the Wellington one is better!

[chaos rider]

im back
yes i had an off in the first race of round 4 but despite not racing the rest of the day and not racing in round 5 i still pulled 3rd place :third:

the monster is out of action for now due to carb problems i think some dirt from the crash my be the problem, and im thinking of re building her into a cafe racer.

nice to see the thread is still going
hope to go racing in the near future and would like to see you all out there with me:Punk:

[ducatilover]

im back
cafe racer.

:

Good man, twin pipes are a must though....
Good to hear you managed third place dude! :yes:

[chaos rider]

well of course it will have twin pipes, question though how do you think that will effect the performance?

[ducatilover]

It makes it easier to make a tuned length/equal length system sometimes, which is obviously a plus and you won't notice the extra weight.
It looks bad arse too, which is why I did it. ;)

[quickbuck]

After a sucessful talk with Carl at MotoRad about a Proddy Lite bike that the shop had sitting there... Then a trip to a school at a race track a bit north of me... And the purchase of a few tools and spares, I am all geared up for Round 6.

Who will I see there?
Woody you going?

Dyno? Hell, didn't you spend enough at a certain school recently? Remember the throttle rule? ;)

I think I will be doing the 27th and 28th at Taupo, but not too sure where things are going after that.... See, my talent as a spanner swinger is still required at the nationals.

Yea haahha it was expensive, but deciding to sell the road gear will pay for the dyno, the thing is when you've only got 28-30hp, if i get 2-3hp from abit of playing around with the bikes EFI that will make a huge difference.

Yea the 27th,28th at taupo should be good.

How do you 'play around' with the GT250r EFI and still remain within the Pro lights rules? I didn't think they were an ajustable unit?

well as many would say.....its the same as putting new jets in a carby version...just mnz havnt made the rules around bikes with fuel injection.

[ducatilover]

well as many would say.....its the same as putting new jets in a carby version...just mnz havnt made the rules around bikes with fuel injection.

So you're going to run increased duty cycle on the injectors and adjust the injector and spark timing? I'd love to see the mapping on one and have a go too, do you have to re-flash the ECU? Or can you plug-play them?
I would ask them about it first in case (I know, it's a cool idea) it bites you in the arse when you start leaving Hyos behind on your own Hyo, down the straights :sunny:

[puddytat]

well as many would say.....its the same as putting new jets in a carby version...just mnz havnt made the rules around bikes with fuel injection.

I'd be careful....I dont think youre even allowed to fuck with jets.
I'd check the rules...



Which I just did....you can fuck with jets & slides.
" Ignition, Engine contol module/unit (ICM,ECU,ECM)& wiring loom must remain as standard." Seems pretty clear to me.

[Racey Rider]

I might just Bore my GT out to 300cc -as mnz havnt made the rules around my lack of riding ability.

[imdying]

" Ignition, Engine contol module/unit (ICM,ECU,ECM)& wiring loom must remain as standard." Seems pretty clear to me.Not really... he's not changing the ECU, or the loom, just some of the values that exist in the program for the ECU.

Besides, let's see them prove it in any case... he's not cheating until they prove it.

If ( The operative word) he has any sort of advantage on the straight with an injected Hyo, unlikely as they had less power to start out with, it is possible to check via diagnostics and run some real time data to see if the engine is running factory specifications on the ECU side of things. Assuming of course they have a diagnostic port. If not, It could be checked to see if the ECU has been opened, re-flashed etc etc.
Not much point, I'd focus on getting tires and suspension set up correct and some practice....:innocent: Get some more braking power, it may help.

Believe it or not but you dont know shit, from factory specifications the EFI hyo's have more power overal,and when coming out a corner the difference in power is noticable, considering you havnt ridden both like i have and and compared them your hardly in the place to comment.

What im planning to get done tommorow is a simple dyno run to see how the bike is running, if its too lean or rich ect, from there the guy from tripple zee cycles said you can work with the origional ECU, instead of using a Power Commander to tune the bike to its after market pipe.

AHHA yeah well ive done every thing to suspension that the rules allow, and im running sinthered brake pads up front, and Pirelli diablo super corsa's....so it handles pretty dam good.

Are they known to have fueling issues? I know the carburetor models were making a mighty 33hp/24rwhp on a good day and the injected ones are meant to be 28-29hp at the crank. As far as I know I haven't ridden the injected bike, but, nor do I have a want to do so unless purely to ride the old vs new back to back. Pull me up dyno results of w.h.y to show the injected model is gruntier and I'll be happy.
I'm glad to hear you have also done the suspension/brakes etc, just don't be the new Chaosrider.....

Well the EFI bikes dont actualy make more horse-power, BUT the way the power comes out of the bike is what you'd call "more responsive". Who told you the injected one are 28-29hp at the crank?.

Ive ridden both EFI one and CARBY oen at taupo, both with same tires,suspension set-up ect, and the difference is there...not down the straight but coming out of corners.

Even just listening to my EFI one next to kens carby one you'd side with me, cant wait to get the bike on the dyno, then we'll see i guess.

[ducatilover]

My mistake, most factory claims are 27-28hp sorry.



Ive ridden both EFI one and CARBY oen at taupo, both with same tires,suspension set-up ect, and the difference is there...not down the straight but coming out of corners.

So it has more torque? Or just a nicer power delivery? I may go try find a place to let me ride them back to back, I'll ride yours, you can ride mine :drinkup: :scooter:


Even just listening to my EFI one next to kens carby one you'd side with me, cant wait to get the bike on the dyno, then we'll see i guess.
I'm not deliberately being a wanker, but I'd expect 23-25hp and some minor variations withing Dynos. Will be very interesting to see, I'm more interested to see the air/fuels and the power curve in comparison to a carb model. :yes:

[quickbuck]

Okay,
This is what I have discovered....

Ninja 250R was leading the field by a long way, and holds the lap record for class at Manfeild - 1:31.250 (One Ben Oxham).

Put my body on it, and it is the same speed down the straights as the Carby Hyosungs. Fastest lap a 1:33.303?
Woodys EFI Hyosung is much quicker in all regards at the Ninja now.... Then he weighs about 1/2 of what I do.....
A 1988 GPX250 is much quicker than me, and has much more power, but still a little off the Class Lap record......

So, we (Okay, read I) could sit here all day on the net about the difference in a couple of HP, but at the end of the day, all I really have to do is loose weight, and ride faster...............

All that said, for those considering the class, I can say it is HUGE fun, and VERY close! We just need more bikes in it.

Give it a go people...

[ducatilover]

Or, keep the weight, throw a leg out like Rossi. It'll pull the babes :niceone:

[puddytat]

Well Ive had a pretty good time doing the King of Ruapuna rounds,had a major breakthrough at Rnd 3 & knocked 3 secs of my P.B....down to a 1:56 now, so keepin' up with the front runners which are all 150's ridden buy the likes of the Hoogies, Seth, Blake et al. & running a consistant second to Jock Woodley in the Streetstock senior class. Been enjoying my starts alot & if i qualify well then i was able to stay within cooee of the frontrunners.....enjoying the heck out of being with the leaders into the first few corners.:shit:
Awesome fun, great racing,fantastic club & me loves me 2nd place trophy:yes::second:230433230434
Shouldve done RND3 of the Sth Isl cup as a couple of the quickies wernt there...couldve had a win maybe? :corn::violin::soon:

Surly it doesn't have to be an original Hyosung part?
