Ok here is the deal. when i first bought my bike in 04 i could barely keep the front end down. Now it feels like a sled. both the stock o6 busa and the slightly modded 10 ate me me up so fast. i have 15,000 miles on the bike and i just threw on a 43 tooth rear sprocket. I have alot of chrome and just some yoshi slip ons. I change my plugs 4,000 miles ago. i never synced my throttlebodies yet, but would that cause that much loss of power? any thoughts or anyone else experiencing the same problems?
