I have recently acquired a 86 trx250r with a spun rod bearing. I had the cylinder bored and a new oversized piston. I just plan on playing around with this 4 wheeler, no serious racing.
My first question is should i replace the crank with an 86 short rod, or should i go with a 88 with the long rod. Or is this even an option. I have done some reading and have read you need a spacer plate to do this, and is this the only thing i will have to do to make the long rod work. I have found some hot rods cranks on ebay that i plan to use.
Also one other off the wall question i have is what does the antifade locknut do on the rear brake/ axle. I have seen a coulpe of them on ebay and i do not really understand their function.
I know these questions are odd but i am new to the racing side of atvs but i do have a 750 brute force and a 450 foremen both heavily modded.
Thanks for the advice.
