Default 85 ATC 250r/CR500 motor

How intense of a dragster do you guys think I can make with an 85 ATC250r powered by an alky driven CR500 power plant? I'm talking about 300' sand and dirt drags.

What's your opinions and advice?

honestly that would be a very sick machine.
but you wanna know what would be even better? a 86-87 tecate 3 with a 640cc kx500 stroker motor on nitro methane.oh about 150 hp or better in mild tune.
if you don't have to wipe your a$$ clean after a ride aboard a machine like that then you need your head checked.
but either way the 250r with the cr motor would still be very fast and you can build that motor to big cc's and run it on methanol.although i honestly believe the kx500 is a much better choice for serious hp.but thats my opinion.everyone has one right?

well i have a 86 cr500 powered 86 250r , and in the mildly modded form that it is in its very fast,,,,,, its a blast to ride too the swingarm is 4" over stock and not near long enough to keep the front down, i'm building a 8" over arm now , it still looks like a 250 so there are alot of guys that can't believe they got beat by a 250r,,,,

I'm trying to beat down some of these 500cc alky banshees around here, I'm going to bore the motor as big as it will go.

Sounds great to me. As a matter of fact here is one right here. I think that it's for sale too.

Hey Kasey. I have a 7" over swingarm that was on my atc500. It worked great for me. I am trying to sell it if you are interested. E-mail me. rodknee@cdsnet.net
