How much $$$ are we lookin at to do this?

[Pitster]

Not completely sure yet, but should have the info soon. Basically it is a longer stroke same size bore, so its not too bad.

[SuperFoot]

[nomotornofun]

yea the crower power motor in my bike (DEMON DAVE) pulls hard on long straights and out of cornors .

rear wheel horse power is right at 10hp with race gas and a knobby tire ( when reading dynos graph's be sure it's rear wheel readings and with the tire type that's used for motocross ) remember this is only a stage 1 dyno graph.

i hope to have a big bore motor by metzfest ( mid-november ) but these things take time.

but one of these with a bigger carb,inner rotor,head work ect and you'd be rocking lots of horse power .

The 145cc is going to retail for about $950 (for the work to be done to your engine) Pulls like a freight train! Anyone with a Pitster Pro engine (GPX) can get this kit done in about two weeks. Or you can buy an engine complete with ALL the work done for $1295. call for more details.

Thats a 145cc start in any gear four speed manuel with carb ready to race!

866-686-7869

I promise I'll have dyno's ASAP.

950 for the work being done to your engine, you dont have parts you can just purchase? the 950 seems a little high for just a stroker.

[Pitster]

The prices are not for sure yet, we are getting the parts in mass now so that we can get the price down.

sweet! ill just take the modded crank........maybe you guys can do a big bore at the same time? bore'd and stroked with a hot cam and a big carb would rip......

[Jimmy Pang]

is 145cc the biggest you can go, how about 160cc or even 200cc pitbike? I'll bet if you made a pit bike with 200cc engine you would have alot a plenty of buyers. I know i would be buying one!

[Outlaw Powersports]

Man what would you do with a pit bike with 200cc? Add a longer swing arm rake out the front some more and drag race it. I thought 125 was plenty, know everyone is hopping around for the 145. I guess "if you build it they will buy".

[Jimmy Pang]

pit bike drag racing? what a good idea!!!!!!!!! I'll be up for that. I'm really into drag racing, I've got a 12sec honda crx vtec turbo with zex nitrous system (300bhp from B16a engine)
