So when i first built my bike my builder recommended 28s.I ran them for awhile but never seemed to get them right. they bog on the bottom and the top. Tried everything builder recommended and just hated them. It raised alot of questions with all my buddies on why not 35s or at the least 33s. Now the riding style i described to my builder was hill climbing, playin hard in the trees, joy riding and the occasional drag race. Ive noticed a few bikes that are built similar too mine run usually 35s. Im thinking of going back to the duel carb setup. Right now I run a single 35 and it runs great except for 5-6 gear it just falls on its face on the top of 5th and dies in 6th????????? My mods are in my sig. what do you guys think. :cool:
