Tz350 new engine idea. Will it go bang?

[Buckets4Me]

the new engine is finaly getting finished
what will happen

[ajturbo]

looks like most of us who have voted have sat on the fence... hahahahahah...

the real question is....

will it beat the GT ??????

[koba]

Band?

IF that is bang - Methinks it won't go bang, but it MAY go slow, or fast.

[F5 Dave]

I voted Maby because I'm not quite sure what that means so its bound to be right.

[bucketracer]

1.8 liters of explosive mixture in the plenum, I voted "Yes"

[SS90]

I really wish I knew the answer to this....... I feel that the disc valve will be the let down of the system, and feel that this is a better situation to use a reed valve, however, I don't feel that would solve the problems that I suspect may come up, but I feel it will alleviate them..... I am really interested in the result, as I can see a use for it in my engines....... argh.... my gut says "big arse inlet fire", but I am open minded.

[Yow Ling]

I went with the big bang theory on this, mostly because it makes me think of the Large Hadron Collider (LHC) the particles enter through the Carb and are decellerated into the plenum in a semirandom swirling gurgling way, as they swirl the fuel is accelerated into the plenum walls where some seperates out and runs to the bottom of the plenum the engine is running lean and going like a castrated cat at lap 9 of the GP TZ tips into a right hander and the now 1/2 full plenum gets emptied into the crankcase causing a hydraulic lock and slightly bending the rod . Apart from that it will be awesome

[Bert]

.... carbonizing his bike, has any one else smoked their ride?

not sure if i should admit to it,
but yes (not my bucket, nor on the track) but a very flooded ZXR with the plugs out, while resolving a missfire a night before racing.
lost my eyebrows and a fair chunk of hair and most of the upper wiring loom and airbox; lucky the tank was off and someome else was there to turn the hose on it....
Though i learnt a few good lesions though; how to wire up a zxr and not to turn the motor over with the plugs out and live.

[bucketracer]

And what won?

Not an FXR.........:girlfight:...........

[Henk]

Have been present when a Z1300 got an airbox full of ether in an attempt to start it after a long stand in a shed. The backfire through the carb resulted in some hasty work witha handfull of shop rags to put the flames out.

[bucketracer]

not sure if i should admit to it,
but yes (not my bucket, nor on the track) but a very flooded ZXR with the plugs out,

A few TZ's have been incinerated this way too......aye TeeZee......

[SS90]

I had a conversation with a highly experienced professional Austrian two stroke tuner last night, and the conversation came to Teezee's latest plan.

I am not trying to discourage Teezee (quite the opposite), but, apparently results (positive ones any way) may be hard to come by.

I am now of the opinion that a 1.5l plenum is about double that of what his engine will be able to use, and the carburation will be similar to simply "over carbing" an engine.

However, Teezee, can you find an old reed block that you can mount between the carb throat and the plenum?, it won't be a lot of work (perhaps a scooter matic one from a Chinese scooter from a wrecker), and it seems it will help control over rich situations........

[Henk]

This may be completely wrong but if the plenum starts out too big will Teezee be able to tune by reducing the plenum volume by introducing suitably restrained ping pong balls or something similar to the chamber?

[SS90]

Well, I think he will have to reduce the volume, but how he does that (if he indeed has too) will be interesting for sure.

It's all theory right now (which was the purpose of this thread), but I believe that there may be a few incarnations.

It will however, work, albeit not perfectly.

[Buckets4Me]

This may be completely wrong but if the plenum starts out too big will Teezee be able to tune by reducing the plenum volume by introducing suitably restrained ping pong balls or something similar to the chamber?

dont give him any idear
this is starting to sound like a nail bomb (think the rest of E.S.E will wait till the restart to line up on the grid with him at the next gp)

[TZ350]

Good idea, :niceone: might use that gap filler expanding foam that you can get in a spray can.

.

[Henk]

As long as it doesn't disolve when exposed to fuel vapour. Could be a sticky mess if it does.
I have heard of ping pong balls used to reduce volumes in the past. Think it was to get the max possible fuel load in a tank down to legal levels but not 100% sure

[Buckets4Me]

Good idea, :niceone: might use that gap filler expanding foam that you can get in a spray can.

.

the flamable stuff ??

[TZ350]

Does gap filler disolve and is it flamable.......:Oops:......hadn't thought that through, still the ping-pong balls idea looks good.

[aircooled]

yep ping pong balls look good, you could number them & take side bets on which one gets sucked into the inlet?

[Buckets4Me]

Does gap filler disolve and is it flamable.......:Oops:......hadn't thought that through, still the ping-pong balls idea looks good.

they would be about the same size (as the port ) wouldn't they ????
golf balls would be better they hurt more in case of an explotion (think of the mind games you could play.)

When you've got 24 and can get through a season without splitting the cases let me know.

ill more than let you now......ill be doing power wheelies up and down the front straight {i think}

it would be easy enough to get 24hp out of my bike, veo vince racing exhaust,power commander + dyno work, 150cc kit with DOHC head, high compression piston, ect

Its all on one website, just got to scrape together about $2000..........forget about it!

well we only pulled my bike apart (and didn't even crqack the cases)

that was after 5 years racing
so team E.S.E can and do build reliable bikes
they also fix things before they brake ( well before )

my bike has been more reliable than any of your's

and most other bikes out there
35 + crashes on it so far (2 broken colla bones)
and only gone threw 2-3 brake levers :)

All very encouraging, I am sure one day someone will make 30hp with a CBR but it will take more than bolt on bits to do it. What size is the throttle body on your bike Max. Well my bike is getting more honda buy the day might have to look closer at these engines. FXRCBR or would you call it a CBFXR? Anyone got one in the shed ha ha yeh right.

[woodyracer]

put on a cbr125r fuel injection system!........then you'll get some more ponies

i love that leo-vince pipe..........abit too expensive tho Id have to go with cbfxr, how is your bike honda??
dont knw how big the throttle body is,

True we scuffed a piston but the bike didn't retire..... finished every race and 3rd overall Taupo 08

scuffed another one on the dyno, cold sezure I think, still made 21 rwhp afterwards, used that piston at Taupo 09

Well the power commander makes it all a bit more obtainable. The limit will be the throllte body if its to small then it would be like trying to make heaps of power on a 2 stroke with a 24mm carb. dig dig.

Secret plans. Pah they are not secret. Like everyone I want to win the thing. The bikes not the issue its the rider.

[Pumba]

Alittle off topic, but what the hay.

As far as throtle bodies go for an injection system I have always thought scavaging the parts off a GSXR600 or somthing simular would be the way to go, I have never looked that hard at the practicality of undertaking such a task because with a standard engine the gains are just not there, and two I cant imagine it being an inexpensive excercise, especially if you have no knowledge of developing such systems.

I have heard talk of just using a carb body as a throttle body for the injection system as well.

I looked at the GSXR stuff. They are 40mm down to 38 at the manifold. They have 2 butterflies to make them work at different rev ranges, all looked a bit complicated to me. 2 big aswell I would guess we 150 types would want something around 30, 32.

How?

from what others have posted, 15hp is your lot, and that is with a power commander

Like I have said Woodyracer, 15 horsepower comes from 20 year old 125cc singles with GN250 carbs, and some guys with FXR150's are getting substantually more than that.

Sorry mate, the addition of fuel injection does not instantly bring power.

Cripes, 10 years ago we pulled an injection system off a Triumph T595, and fitted it with a set of Mikuni FCR flatslides, the damned thing instantly made 10 horsepower more, and revved out so much faster that we had to convert it to under bucket shims (from the factory bucket over shim set up) just to stop it spitting shims out.

No mate, fuel injection does not always mean more power.

[F5 Dave]

A fair call. FI has been brought in for emissions control & can be made quite cheaply. Top level GP 2 strokes all ran carbs (with a few exceptions like Itohs NSR). 750cc superbikes ran with carbs while they could as std on roadbikes. OK things have moved on & FI has caught up, but it goes to show how close it was, but hardly expect a production FI system to be a step up from a decent carb.

Of course you could run a GSXR600 with 3 cyl blanked off & that would give you a 150 with FI all set up for that cylinder..

The 2.6L supercharged outboards are ditry four stokes. The evinrude E-tec 225 or 250 would be the engine pick of the moment (2 year racing warenty as well), personally I love the Mercuary 300X (I have an afinity with mercs) but along with the Yamaha 300, and 225 they seem to have developed a nasty habit of blowing up latley (bloody two strokes)

Now wack any those bastards on the back of a fishing rig and it wont matter if there are fish or not.

[Yow Ling]

we not worried yet, testing isnt complete. Have you thought of the merits of on board fire extinguisher.

Did it used to spit back when it wasnt a plenum thingy or is this a new thing. Do you think this is a disk valve thing, its hard to imagine it happening on a reed valve engine.

[TZ350]

we not worried yet, testing isnt complete.

"not worried yet", you should be seriously worried I would think….:laugh:

but as you say. "testing isn’t complete"..........whatever problems there will be getting it all running properly, we now know a spectacular plenum blow up is not going to be one of them.

It starts easy, idles, runs better with some re-jetting and does not blow up after a backfire, so getting there.

[TZ350]

Do you think this is a disk valve thing, its hard to imagine it happening on a reed valve engine.

Full system load of air/fuel mixture, wasted spark ignition, backfire could happen to any motor.....

but backfire through the carb on one with reed valves, not sure??? intuitively wouldn't think so.....butttt......

[Henk]

backfire through the carb on one with reed valves, not sure??? intuitively wouldn't think so.....butttt......

Have seen this on an RM250 with a dodgy earth on the coil. Would backfire through the carb and leave witness marks on the inside of the air filter.

[RMS eng]

70s plenum tube for KX125 ,made by sunk works, so you could run a bigger carb 26mm-32mm.

[TZ350]

Yes...good idea, now that I have seen the picture I think I remember it from a Kawasaki trail bike manual. At the time I thought it was for changing the tuned length. But I can see how this could be made as a plenum chamber like mine, but with less volume. Thanks for reminding me of it, it could be very usefull if my current plenum proves to be too big.

[Buckets4Me]

also get the carb out of the way a bit :)

Anyone who bet it would blow up has seriously lost there money and I think the maybe's have done their dough too, but whether it can clean up at Taupo, well it won't, not with me on it anyway.

so Taupo would be the place to blow it up.
But your not up to it

Summer loving had me a blast
Summer loving happened so fast
I met a girl crazy for me
'Met a boy cute as can be
Summer days drifting away to oh oh the summer nights

Tell me more, Tell me more
Did you get very far
Tell me more, Tell me more
Like does he have a car

She swam by me, she got a cramp
He ran by me, got my suit damp
I saved her life, she nearly drown
He showed off splashing around
Summer sun, something's begun but oh oh the summer nights

Tell me more Tell me more
Was it love at first sight
Tell me more, tell me more
Did she put up a fight

Took her bowling in the arcade
We went strolling, drank lemonade
We made out under the rock
We stayed out till ten o'clock
Summer flying don't mean a thing but oh oh the summer nights

Tell me more, tell me more
But you don't gotta brag
Tell me more, tell me more
Cause he sounds like a drag

He got friendly, holding my hand
She got friendly, down in the sand
She was sweet, just turned eighteen
Well she was good, you know I mean
Summer heat, boys and girls meet but oh oh the summer nights

Tell me more, tell me more
how much dough did he spend
Tell me more, tell me more
Could she get me a friend

It turned colder, that's where it ends
So I told her we'd still be friends
Then we made our true love vow
Wonder what she's doing now
Summer dreams ripped at the seams but oh those summer nights

and seeing as I cant ride that well (and I dont want to die)
I hand you the flame (dont hold it to near the carb)

[Henk]

I've ridden plenty of two strokes in my time so I wouldn't be completely lost, still prefer to ride mine when it comes to racing since I prefer to break my own toys over others. If you guys do need a crash test dummy I wouldn't mind having a go but you're probably a better candidate than me.

im a good dummy, i crash well

I was impressed by the number of times you got back up, last Sunday at Mt Welly.

haei only crashed once!, there must of been an oil spill cos me and kieren both hit it.

[Henk]

The way things were sunday morning it may have been a water spill.
My two crashes in exactly the same place Sunday morning at the surface change coming out of he infeild are begining to make me think I might have to go to slightly lighter fork oil.

water makes me faster!!.....i was coming second until............ahaha, it was unbelieveably slippery......

someone crashed infrount of me and if I had to get off the bike to help I would have slipped over it was that slippery

that track can be nasty when wet

sure is.. im remember falling on my face when i went to broom puddles of the inside corner a few years back..hahah cant believe we ride bikes around it..hahah

Can it be fixed? Drainage work etc.

[Buckets4Me]

remove the carts and all the oil from the 2 stroke petrol ( is no not a chance the track is just slipery. Much like a diesal spill)

no standing water just a damp track :P

[TZ350]

The "No"s take the money:- http://www.youtube.com/watch?v=p4ef-WUO1Qs

[ajturbo]

they need to re-lay the track... wonder if there is any left over from H.Downs???

ask luke how slippery it is...lol

[Buckets4Me]

Luke how slippery is it ??

[Henk]

Quite slippery, I was a litle worried when I saw that he had gone down halfway through the sweeper runing the oval anticlockwise, was incredibly relieved to see him moving.

[Buckets4Me]

didn't relise anyone crashed doing the oval :(
thats a bit fast to be lying on the track with other bikes wizzing around

[Henk]

He fired himself far enough up the bank to be out of everybodys way.

[ajturbo]

i find that when people fall off in front of me.. they tend to slow my bike down.....

[craisin]

so did it blow up?
or did he can the idea

[TZ350]

Dad was out on a job so we had a bit of fun at lunch time, probably get our arses kicked later for fu..king around at work.

In the first moments of the clip you can see how easy it is to start from cold, and that there is no blow back from the carb.

Warming it up before a bit of a blurt up the drive.

Runs ok and has even been out on the track without blowing up.

With it running on pre-mix and leaving so much of the oil behind in the plenum I was having real doubts about how much lubrication was actually getting to the engine.

The project is promising enough for me to make another engine with an “Auto Lube” system and fit it to the new FZR rolling chassis.

[craisin]

thought I might see a wheelstand

[Buckets4Me]

belive it or not it worked and dynoed well to boot

[SS90]

I don't believe you.
Post the results.

If it made half a horsepower more than the 22 HP (that has always been claimed, but never proved), then I will close down my Kiwibiker account, and never return.

Oh, and I want to see a video of it on the dyno as well (just in case someone "pads" the results)..... you have nothing to lose, and everything to gain.

well guess what

I'm not surrprised you dont believe me but thats up to you

Ohoo BoooHoooo please don't do that, where will we be without the sniviley kid, to give us laughs........

Sounds like the death cry of a woofter hiding behind his dad's skirt with nothing left to offer except personal attacks on someone he has never met.
I will increase the offer.

On top of my previous offer, I will give you €1000 cash, if I can be present at a dyno run for the "flying vacume claener", in New Zealand, in two weeks time, using a dyno of my choice, in Auckland, on video.:scooter::scooter::scooter::bye::bye::bye:

[bucketracer]

Pure genius........... I'll give Thomas €1000 Euro if he starts contributing.

Hello Captain Underpants please re submit your offer after you have paid Thomas the thousand you owe him for putting you straight on crankshaft balance factors and all his pictorial contributions.

Come to think of it you probably owe me a dollar or two for clueing you in about what a formula actually is.

But personally I hope you don't or probably can't as your someone I would be loathe to spend any time with in real life..............

Come on, put up or shut up.

[bucketracer]

Ok piss and wind, you already owe Thomas, so payup or shut up

[SS90]

You owe Thomas, Payup or shut up

Post a video and dyno run of your daddy's latest abandoned project, or I am not going anywhere.

[bucketracer]

SuperStupid I don't think you have got the readys and you probably couldn't understand what you saw anyway.

[SS90]

:blink: why do you turn everything into a bitch fight. I remember we used to have a guy from Ireland who wanted to introduce buckets there.......he contributed to Bucket threads...... he's gone..... he posted something referring to "Dick measuring teenagers"...then he never appeared again.


For the love of god, grow up.

Ohooooo didums you will be running of to mother again like you did last time I kicked your arse.........:crybaby:......you big cry baby

Probably time for you to put up something useful or shutup

[SS90]

And you just killed another thread.

Thanks Genius.......

Thats more like it..........

you like a good thread bashing do you ?? :)
kinky bastard !

next you will tell us how good those chinese engines are

[craisin]

get a grip take it to the tip get it off the truck with a flip

[Buckets4Me]

Thanks Genius.......

so true so true


Only because you and Squiggles have asked. I thought it was only that twit SS90 that was interested.

I can say that it didn't blow up and its first dyno test session, if not spectacular was at least encouraging.

Its the first cut and I would have liked to have completed some more development........

A lot of our recent work was inspired by some sensible and constructive posts earlier from Sonic_V they are worth another look….……





This is from memory, and remember Johns dyno only graphs rwhp against road speed so rpm has to be calculated.

The original engine with a std 24mm carb and an inlet duration of 225deg made 19+rwhp at 11,250 rpm.

The same engine was fitted with a barrel that has enlarged transfers and a reduced exhaust duration as suggested by SS90 and a 24mm venturi carb as suggested by Sonic_V which was fitted conventionally on the side, it made 21+rwhp at 9,500rpm. It ran best on a 130 main jet and was a strong runner at Taupo.

Same engine, same carb same 225deg inlet duration but with the plenum chamber, it was frighteningly fast up the drive on Taupo gearing but suffered badly from a flat spot below the power band at about 4-5k rpm.

Sonic_V in one of his early posts had suggested an inlet closing point of 60deg ATDC, for a duration of 205deg.

Same plenum engine, same carb but with 205deg inlet duration it still suffered from a lesser but significant flat spot below the power band at about 4-5k rpm.

Reducing the closing point to 45 then 35 degrees ATDC for a duration of 180 reduced the flat spot but it still made the bike unrideable in competition.

Increasing the inlet tract length inside the plenum by 35mm cured the flat spot and it was rideable on the track at Mt Wellington in the wet.

Now Dyno Time….

21+rwhp at 9,500 rpm from the conventional engine with 225 deg inlet duration Sonic_V venture carb SS90 barrel, Honda RS125 chamber and 130 main jet.

20+rwhp at 8,500 rpm from the same engine fitted with the plenum and 180deg inlet duration and it ran best on a 185 main jet.

Interestingly the plenum engine made much more hp below the power band, about 4-5hp every where and this extra low down grunt probably accounts for the wheel spin when giving it some big throttle during testing at Mt Welly.

Testing stopped when we realised that there may be a lubrication problem as most of the pre-mix oil was being left behind in the plenum. To do any more development I will have to build an auto lube motor to go with the plenum.

As the BMEP for 20rwhp at 8,500 is a whole lot better than for 21 at 9,500, it will be interesting to see where the plenum idea goes with more inlet duration and barrel/chamber mods as suggested by Sonic_V for max power at 10,500.

Team ESE are building some new chassis and I have taken the plenum off old Blue to use in the new bike.

So there you have it, encouraging but not spectacular….. "yet"………

Gentelmen do you want to place your bets?


well I guess it's still on then
bring on Taupo 2010

You do realisse that with your filthy chineese diesel you are single handedly responsible for global warming.

On a brighter note, whats the outcome of the sweep? It didn't go bang, it did go thud and it didn't clean up. Does that make my maybe vote the most accurate?
