Is there any way you can increase the BHP/HP on bike? If so what modifications are required?

Easiest way is to buy a bigger bike.

Best way I have found is to locate a forum specific to your bike and see what mods others have done. Often there as a few very smart individuals or companies whom take a special interest in your bike and have extensive knowledge of what works well and what doesn't on your machine.

You can save yourself a lot of time and cost and often times gains can be had very cheaply.

countless ways if you've got the inclination/time/money to do it

if i was you i'd get rid of those chicken strips before worrying about moar power

or maybe get a four stroke with grunt all through the rev range rather than a gutless two stroke with a little squirt at the top

depends on which bike you have.
The old ROTAX motor was good becuase while it was a strong motor - it was hardly a refined motor.
Throttle bodies were cast alloy - so the first thing i would do is get some fine wet/dry sandpaper and some polishing pads, even a dremel - and get the flow to the inlets nice and smooth.
Also stuff like: adding iridium plugs, K&N airfilters, exhausts are good "bolt-on" mods for extra hp.
I would also recommend a re-mapping if you want better power delivery.

Oh yes. very easily.

Painting it red will add 15% extra horsepower.

Judicious choice of decals can add up to 10%

Adding a very noisy exhaust will add 10hp + 1 extra for every decibel over 95.

Just wearing a toothpaste suit adds 15hp

And if you can get the rego changed to incorporate at least 3 'R's in the model designation, that adds 25hp.

Before you even think about more horsepower, rebuild that bloody top end before it explodes and you have 0 horsepower! Do a rebuild and then it won't run so shit

40 thousand something k's and no rebuild :no:, i feel sorry for your rs. after that you can have a play around at boosting power.

What chicken strips?? And aren't 2 stokers designed to output twice the power ratio e.g. 250cc is equivalent to say 600cc??

What sort of a rebuild are you planning? Just new pistons etc? If so, do you know what size the current pistons are? If they're already oversize (which would mean it'd had at least one rebuild in the past) you need new pistons that are oversize too.

Well looking at replacing the piston rings and base gaskets. Not sure if the pistons need replacing. As for the current piston sizes, I'm not entirely sure as far as I'm aware, it hasn't had a rebuild. I could be wrong. What's your schedule like? Thinking could have a look at it sometime this week??

though my exam timetable means i'll be keen as soon as lectures end

25th october :D



What chicken strips?? And aren't 2 stokers designed to output twice the power ratio e.g. 250cc is equivalent to say 600cc??


last i saw that bike had them strips:bleh:


250 times two is 500

it all depends on cylinder arrangement and then there's the rest of the bike too... and then the rider

as a general rule you double the capacity (ie in single cylinder motox the 250cc 2 strokes race with 450cc four strokes, while 125cc two stroke race with 250cc four stroke, but in F3 class the four strokes have 400cc 4 cyl racing with 650cc twins), but things keep skewing as the four strokes get better while two stroke development grinds to a halt (damn hippies)

so performance wise your RS250 is on par with the VFR400 - remember though it's a different sort of power

the RS being much lighter with no engine brake, and all the power at the top end
vs. the VFR - much heavier but low centre of gravity and useable power right through the rev range

either way those two bikes are considered the best machines under 600cc ever built


I think your priority should be a rebuild, and maybe chuck some bolt on performance mods in there while we're at it

but be careful - often performance comes at the cost of long term reliability

25th October sounds good. Am going to try and source the parts (piston rings and base gaskets) today or at least hopefully this week. Rebuilding it definitely a priority. Bolting on performance bolts would be welcome :-)

ok you have an RS250 and still have hp issues????
just do a full rebuild, and pay the extra for a set of iridium plugs.
as long as your compression is good the bike should be honking around the 230+kph area.
Also ride fast - if you don't your engine will hate you.
RS250 is not a commuter.

I wouldn't say I have HP issues however would be nice to get a little more performance out of it at the lower revs. Already have a set of iridium plugs. Now when you say a full rebuild, what do you mean exactly? Tend to average around 140 kph with the occasional 180 and 200.

Given that the RS250 is probably one of the half dozen fastest bikes of ANY size, point to point, on the roads (and on some roads, the fastest), one feels that the OP must either be an enormously experienced rider with balls the size of watermelons, or does not understand how a two stroke must be ridden.

I wouldn't say I'm an enormously experienced rider but don't mind pushing the limits if I have to (and within reason) but found that am always losing valuable ground when dropping gears and slowing down around corners and want to ride fast out of them...unless I'm doing it completely wrong...

you should be entering the corner in the correct gear you want to come out of the corner in (ie in the powerband), not fucking around changing down mid (or after) corner trying to find the correct acceleration.

if you arent doing this, all more horsepower is going to do is allow you to fuck up the corners faster.

remember its a rs250, you will always lose ground to a more powerful bike in a straight line.

Ixion
6th October 2008, 12:59
..unless I'm doing it completely wrong...

You are. The only limitation on an RS250 corner exit speed would be the need to keep the front wheel on the ground.

Quite seriously , there is NO bike on the roads that would be faster than an RS250 through the corners.

Over 200kph on the straights, litre bikes will overhaul you. But you should easily be able to retake them in the corners.

Brake brake brake, bang bang bang, scream bang scream bang scream. That's the way to do it.

Correct me if I am wrong. I always tend to enter corners in second or first gear as to allow me to speed out of them as soon as I can.

sorry timati, but i think the latter is the case

that bike needs to be thrashed and kept high in the revs

revving her out will do more for performance than a lot of mods

Am always keeping it in high revs. Funnily enough the mechanic told me that if I keep it in high revs long enough, it's a good way to blow up the engine. Which is the case and hence my confusion???

Listen to IXION really but just coz I'm bored...

Keeping it really screming is going to shorten its life a bit but thats the way it was designed, If you are worried about that you own the wrong bike.

Do some research on the oiling system and make sure you understand it, if it is going to see racetrack leves of full throttle It may be a good idea to add a wee bit of oil in the petrol to bring the oil/fuel ratio for track use but I'm not sure about this bike you own it so find out.

Keep it well maintained.
Make sure the powervalves are set correctly, the exhaust is clean and all that, if you don't know how buy a manual and if you don't want to bother buy a fourstroke.

There are things you can do like making sure the squish is set correctly when you do this top end rebuild, that will help you alot in the midrange but only if it isn't correct to begin with.



If you really wan't to pointlessly throw money at it look here:
http://www.thetuningworks.co.uk/
http://www.rgvspares.com/

Most added power will create a compromise in another area but billet powervalves could be a good idea.

But as long as the bike is running well it is almost always going to be the rider limiting the bike performace so $$ is better spend on developing skill on the track.

Then If you start racing you probably will stop caring about big man speed and power on the road because you will realise its mostly a load of shit anyway.


Mostly random thoughts there, some may help but because its just my opinion its probably mostly wrong anyway.

you rev it it wears out faster, you don't and it gums averything up with unburnt oil

either way it's meant to be a rebuild every 20,000km(?)

sure there's less parts to replace, but (along with appaling fuel economy, oil costs, hot seizures, cold siezures, holed pistons etc etc) having to do five rebuilds before you'd even look at some fourstroke motors kinda negates the myth that a fourstroke is more expensive

Enter the corner in the highest gear that will keep the engine in the powerband. If you are not familiar with the corner, and thus may have to slow further midcorner, drop an extra gear on entry. The thing to avoid at all costs is dropping out of the powerband in the corner.

On exit redline and bang, redline and bang, until you reach the next corner


If you don't redline it (or pretty near) you're abusing it. You'll probably have all sorts of mechanical problems, and more importantly, you risk a serious crash. Remember , you NEVER want to drop out of the powerband in a corner.

It's a tuned two smoker. You need to thrash its nuts off. Rape it, and it'll come back and ask for more.

Two-strokes do that.

But if they blow it's about $300 to rebuild the top-end.

I was thinking of just getting the rings and base gaskets rather than the full kit. What do you think?
IMO it's cheap enough to get a full topend kit.

i think we open her up and look - bike will be off the road til the parts arrive and cylinders finished (if they need it)

or you could buy the kit including bore

or assume it's ok.

Not sure what happened on Thursday night however I was on my way back from town and was on the motorway. Was having a smooth ride when the bike suddenly decided to lose power and came to a complete halt. I knew I had enough fuel as I had just topped up the tank and there was certainly enough oil seeing that I had also topped it up earlier. Anyway, I had to pull away from the motorway and had the bike towed to the mechanic the next morning seeing I couldn't even kickstart the bike the night earlier. I did attempt to kickstart in the morning and there was this clicking sound that I had never heard before and had a few blasts of fire coming out of the exhausts. Anyway, it's at the mechanic at the moment....so will have to wait till I get it back next week before looking at rebuilding it.

You mean new spark plugs? Considering most of you guys are busy and the bike broke down at night, I had it towed the next morning to the mechanic.

lol yeah fair enough - but now we have to get it from there to here;)


ummmm, when you say you can't kickstart it, it DOES turn over right? just wont start?

jets of flame (from one or both pipes?) indicate a couple of things

awesomeness
fuel entering exhaust unburned and igniting
which may be from plugs failing to ignite fuel
or perhaps the power valve is fucking up

Hopefully it should be sorted tomorrow. Mechanic said he's going to have a look at it today. The kick start did turn right. It just wouldn't start. As for the jets of flame, it was from one of the pipes. The upper pipe. It would have been neat if it was because of awesomeness :-).

Cool. Just the items I was looking for.

Sup...
Which mechanic you taking your pride-and-joy to? I for one can suggest one NOT to take it to... :nono:

With the top-end stuff...yup rgvspares.com has the AUD$385 kit as koba has posted
I dont know the full requirements of a tope end rebuild, but Colemans and rgv250.co.uk have RGV toppend kits that are around NZD$600 that add a couple things like gudgeon pins and head gasket to the kit to make up the difference in $$$...

Will hope to have one kit in the mail for my RS250...once my 'mechanic' gets his shit sorted. :2guns:
Or i get my farking $$$ back from him.
Don't frikking ask. :no:

Maybe we can somehow get two rs250s into PirateJafas garage for a synchronised rebuild? :clap:

The bike is going to be at the mechanic's for a wee while seeing the oil feed broke and completely wrecked the pistons and ball bearings. Mike from Davey Motorbikes is the dude I go to. Good bloke and reasonably priced. Won't be doing a rebuild until I get the bike back but if you need a hand rebuilding yours let me know.

As in the oil feed for oil that keeps the cylinders oiled and from being violated as if being :buggerd: with a steel file?

Probbly the least of your worries, but hope you didnt just splurge on filling up the tank with $40/litre synthetic :doh:

Good to hear you fulla at Daveys is sorting you out aye...hoep it continues to be as such.
Felt like crap having to walk into the workshop where my bikes at, and basically TELL the dude there STEP 1 Pick up the phone STEP 2 Call Mt Eden Motorcycles STEP 3 Ask for an RGV VJ22 top end rebuild kit etc.

Guess I should have done that 1 1/2 months ago in terms of top end.
And probably the same 10 months ago for my rear shock.

FYI...sounds that Suzuki has RGV kits available in NZ, so are just a couple days delivery from somewhere south of Bombays - oil delivery issues aside...Bright side is that engine internals aren't TOO far away from your pride&joy then? Mine should hopefully be here mid next week then.

Have also had sudden cut-outs several times before, but have fortunately been able to kick it back to life after many sweat soaked minutes...
Powervalves are probbly causing my block a few issues so could get thrown in the 'to be replaced' list.

Which makes me wan to make noises like Hmmmm...haaaaaa...hoooooo...
and then think "Does anyone know if the VJ22 can be made to run without powervalves and be like Jafa's dual-speed RD?" :eek:

It certainly has been violated. Hopefully I'll have the bike this week!. Why don't you take the bike to Mike? Sounds like the mechanic you are dealing with is daft or needs a baseball bat to get the job done. I prefer the bit where walking in with the baseball bat. BTW who is the mechanic?

Chaaahoooo!!! :D I believe PVs OPEN as the 2T wakes up, so guess they would be fixed to open for racing? I guess the only time it goes below 6K-ish rpm (powerband is GO!!!) is in 1st gear coming off lights, so guess under 6K would be when PVs are closed...ie NOT VERY OFTEN! which equates to i don't really need powervalves...
but more importantly...no need to spend $500 or so all up on a new set of PVs maybe! :woohoo: (esp the desirable billet-centred ones which add ANOTHER $250ish!!!)

Suzuki's full top end kit is just over $600 for the vj22/rs250.
Aprilia's? Allegedly, Aprilia Italy orders from Suzuki Japan, sticks an Aprilia sticker over Suzuki, and ships it to their customer with an markup of around 50%...i.e. Yup...$900ish all up was the quote.

:wacko:

Good news to any people who are thinking 'what SHOULDN'T i do?!?! where SHOULDN'T i go!?!?' Frankly my dears, you dont have to give a damn in this case cos the fulla has gone into liquidation...so no risk of getting YOUR pretties garaged up for what adds up to a year or so.

Seems a baseball bat with a big fulla on the pivot end wasnt needed, just a pen with an accountant on the end.

Hey Timati, didja get the bike a couple weeks back hopefully? how has Mike been to your puppy?

summers in the air, and the best thing to add to the sticky humidity is the sweet smell of berry-scented (and yes it was kinda too tempting... :Oops: FLAVOURED!!!) 100% synthetic 2T smoke! :woohoo:

Hocusing the power valve open won't give you any more horsepower. All the power valve does is 'fill in' the torque curve at low(ish) revs (under about 6000 as someone said). Racers will often jam them open, because they don't use low revs,and it's another thing to go wrong and add weight.

For a racer machine, that's all good. For a "ride to work bike and fang in the weekend" bike, it's not so good. The power valve doesn't add horsepower. But it does make the bike a shit load easier to ride in traffic.

Two strokes are the absolute paradigm of the classic conundrum :

Power
Reliability
Useability

Choose any two. You can't ever have all three.

Serious? i THOUGHT i had all three!!! or maybe love made me blind...

I aint a fussy bugger and the 6K+ range is what I like about it so what i would say is give usability a kick up the a55...heck thats what my uz125 is for! :scooter:

or all three in the ER6 :banana:

NOOOOOW...time for a rebuild, and fang-ination of the RS on a daily basis with no powervalves! got MY vote :2thumbsup

oh dear...the likelihood of me selling the RS is getting lesser and lesser...unless whoever buys it off me will be aight with it being powervalveless! :(

Good to hear - enough to warrant its very own thread i see! :banana:
Am sure you are loving hearing the 2T music ringadingdingdinging in your ears/head once again! They are truly fan-freeking-tastic rides when going sweet!

Mine? After much reading of the manual and online, seems like my actuator hasnt been doing its job since ive had the bike pretty much. PVs seem to have been stationary at the mid level (bit of bottom end, decent middle, little top end). Fixed the powervalves to open and now she flies! When she gets "there"...and never backfires/cuts out, and starts 1st/2nd kick usually.
Also cracked open my air filter while I was fiddling. Twas filthy.

What not-working-powervalves + filthy-airfilter indicates is that I spent around a couple hundy $$$ on my 'Service', and all that the bike got was an expenseive garage to sleep in (at least it was in the company of its big momma and poppa Mille and Tuono...)

It looks like Mr Mechanic did sweet FA with it. Good f***ing receivership/liquidation riddance to him. ARGH!

Anyhoos, tis in Gavin's (Mt Edens) hands now. I'm just gonna sit it out and be patient. I'm guessing a rebuild of shock will be seen to, get the powervalves all working or something, and top-end done. He hope by end of this month or just after New Years. WHo knows...but at least theres the ER6 :yes:

Had a brief fang on a shop floor RS250 at Mt Eden and it kinda scared me for the first couple minutes as was not expecting power from "low" (due to mine having dysfunctional PVs). Hope you will get the same buzz with your brand-new old bike aye! :devil2:
