Can anyone tell me why 250cc bikes have to be either old or gutless?

Two IT465 donks on a common crankcase would be a good start.

[Ocean1]

*blocks ears* lalalalalalalal I'm not listening.

This is how projects like this start... few of the boys having a joke one minute... CNC mill making a crankcase the next

Caught myself thinking exactly that. Ridiculous idea, entirely irresponsible and unnecessary, dangerous.

I do happen to have a fucking great slab of 100mm tooling alloy down in the shop though.

What would you use for a donor chassis?

[Ocean1]

Well, maybe a 916 chassis, it's got room for a thou twin? BUT NOOOOO!!!!

So not a pair of CR500 top ends then?

Could glue them onto the Buell case I s'pose .

Need new rods, and the expansion chambers would be a bitch...

[nudemetalz]

Just an overgrown bucket really....

Can I have a ride of the V-twin 1000 2-stroke please once it's complete.
Just gimme some warning so I can update my life insurance policy....

[Ixion]

What have I started !

Of course, the weight of the huge steel balls the rider will need to have to pin the throttle , will take some of the edge off the performance.

[FilthyLuka]

1000cc two stroke, had that idea a while back, thought it was silly then, think its silly now...

Ill start drawing up plans for a crank case

Also gonna start a thread in Bike Mechanics going on 'bout this...

kx500 or cr500 top ends? hmm...

Relax dude, I'm perfectly happy with the current Briggs & Stratton.

What'd be really cool is if SOMEONE ELSE wanted one, and I was allowed to play with the budget some...

Yup, stupid idea.

Actually the Buell might not be a bad start, easier to make simple c/cases and glue them to the existing box rather than have to machine up a complete case.

Prob knock at least 10kg off the overall weight, and the missing cyl height might just allow over-the-top chambers through the original frame for the rear cyl, front one underneath..

But it's still silly.

Ski-Doo make a 1000cc twin 2-stroke that puts out 170hp and probably a heck of a lot of torque.

I see Buell frame twisting into plasticine.....

[jcupit69]

Heheheh, but you're another stroker owner, you're biased too

True, i'll never sell it, even when i move up, their too much fun, no wonder their illegal to produce

[jcupit69]

No need to be a cock about it... I'm out of rep for now, but you can expect your red in the mail

rotfl, have some green bling for that!!

when someone who just comes on here to stir shit saying other peoples bikes are crap of which they have not one bit of idea about, should I welcome them with hugs and kisses?

and good on you I couldnt care less about your opinion

The Buell's frame is one of their more robust features, I think it would be fine.

I can see gearing changes, chains and sprockets, hassles with fuel delivery, exhausts and cranks though.

I can also see my arms turning to plasticine, should I be so unwise to attempt to ride such.

Just out of curiosity have you ridden (and by ridden I mean done some decent k's) on a larger bike? Not shit-stirring, just asking.

I cant say Ive done heaps of k's, have taken 06 r6 for a few sessions at puke and taupo, as well as on the road
took k6 600 to coro and back
rf900 round the block
05 cbr for a decent spin
Not sure what year but took a 87-89 gixa for a hack, loose bruce was due to pick that bike up the day after his crash so he could make k5 full track

Like I said I havent clocked up heaps of k's but Ive clocked up 20,000 on this particular rs250 and I had another one and a nsr before that

For sports riding over short (<200km) distances, I'd agree with him. Once you get further afield, and don't want to spend the entire trip raping the bike (it does get tiring being on your toes all the time), then having a bit of low end torque to drag you out of corners at low revs is nice

I guess what I want is a hybrid V2 1000cc/250cc 2 stroke I can swap on the fly

I agree with you about the longer distances thing, I recently rode my bike to kaitaia in one hit - 400km each way, I had a heavy BIG pack but still had a good ride, I fit on the bike pretty well though and there were definately times when I wished I could hoist the front at 150k

Im off o/s soon, my goal is to be making swing arms and other assorted parts for aprilia racing, particulary the 250's
Ive lined up storage for my bike and when I get back, begin project rs500
take one rg400 engine, once rs250 chassis, bolt on 4 cylinders from my bike, throw money at it and wah lah, your own special race rep

RGV500
see pictures halfway down of his homemade exhaust system with arrow cans,^^amazing
On the next page she is all dressed up but I would have my own design rs fairings, plenty of carbon

He goes on to have plenty of dyno time getting 130bhp, he says he has owned all the big boys and nothing compares,
somewhere in that thread he reckons it rapes r1's and gixas on the straights at the track

True, i'll never sell it, even when i move up, their too much fun, no wonder their illegal to produce

Bling for that, Im the same

[gijoe1313]

I yam scared of the crazy torque .. or talk on this thread! 1000cc v twin 2 stroker! Pffft! Madness I say! Madness? This is ... KB!!

Please keep posting and talking more of this heresy ...
