good motor for 250r frame?

[ky 2stroker]

I got an old 86 honda 250r frame that im not using for anything and i'd like to maybe find some kind of 2 stroke motor to put in it and make it into a dirt dragger. but I dont know what type motor to go with? the frame is not real good for hard riding like I do, and it needs to be welded in several spots where its broke. and I know its pretty heavy to be used for drag racing but I can clean it up and shave a little weight I guess.

but like I need some ideas for a powerplant. I'd like to stick with a single cylinder 2 stroke, so no banshee motors lol. thought maybe the older air cooled 250r motors would be easy to work with. or find a cheap liquid cooled 250r motor and build it up to decent power. im not wanting to go $$$ all out with 70 or 80+ hp or anything like that. just something that will give average piped and ported banshees a good run for the money. and maybe something to compete with the bro's wr500 blaster thats still in the fine tuning stages. how much trouble would a zilla motor be to use in a R frame? I know that whatever motor i go with i'll consider going with a big bore/sleeve if its available, heavy porting, big carb, run with race fuel, and maybe some kind of drag pipe or topend pipe.

so, any ideas for me?

i think you shoud consider a blaster engine

[flotek]

yz490 cr500 kx500 engines are the choices i would probably use ,all of which will vibrate i n a quad frame but for straight line dragging it wont be a big problem

[ky 2stroker]

well, I was kinda gonna leave the big bore dirt bike motors to my last choices cause I dont like the bad vibration issue. and I could use something very similar to a blaster motor, a air cooled 250r motor.

but since I been thinkin about it I kinda got an itch for a lt 500 motor. since its counter balanced it probably wouldnt vibrate too bad. just not sure with the parts availability. and here lately I aint seen to many complete zilla motors for sale

on old air fooler 250r motor wouldnt be the best in my opinion in that quad frame for a dragger, you could however improve that motor by adding a rare, and sometimes very hard to get hondaline 300 big bore kit, do some port work and add a nice pipe and carb and go tear it up! I know mine does!

why not throw a newer CR250 motor in it. they make around 45-47 horse in stock form. slap a pipe on and your set

Why downgrade potential from stock? If vibration is a big deal then use an LT500 engine... I would use a CR/KX 500 powerplant... With an already less than perfect frame and a primary focus on dragging... Who cares about some vibes?

[370banshee]

to me a cr500 is the only way to go... especially if you wanna hang with a wr500 powered blaster..

[370banshee]

and why a zilla engine? that would be a total waste of time... whatever you use.. plan on spending big $$$$


is this a whole rollign chassis or just a bare frame?

Zilla engine waste of time?
