I have a '92 lt250r that i am setting up for mx. It is bored .30 over, fmf fatty pipe and powercore silencer, delta v-force reed cage, wiseco piston kit, and k and n filter with the air box lid removed. Now, i'm looking for a bigger carb. I'm just looking for some suggestions. Would it work to use a larger carb off of another stock engine? I'm also wondering if wheel spacers are a good idea since i can't afford longer a-arms.

 

i am no carb expert by any means but i do know that using a bigger stock carb from another machine may help but may hurt performance. I have a 39 mm air stryker on my lt250 and it works great. I have alot of mods and would suggest getting this large of carb unless you have port work and all those things done . A racing carb is alot better than a just a large carb from another bike, they allow you to take jumps without sputtering for fuel.
