Title: Long rod vs short rod setup
Post by: Tbus93 on September 06, 2013, 03:40:45 PM

I have an 88 250r motor and and 85 atc 250r motor I was curious what motor I should put my esr 310 big bore the 85 has a boysen rad valve hotrods short and the 88 has oem long rod vforce3 reed setup  I know I'm going to put the 310 in my quad but I was curious if I should just swap the top end on my quad to the three wheeler or just completely swap the motors

I know the ct ported stock cylinder is definitely going on my three wheeler but I don't know if there is much of a difference between the two rods and instead of swapping top ends just swap motors

I agree, the 88 is the better choice IMO but I have seen short rod 310's run very strong and be reliable
