it wasnt stock ok. the guy who owns it has his own comapany who works for case and ships tractors and such. he owns plants everywhere you can imagine. My busa isnt stock either so thats why i run in the low 9's. I know for sure he had a twin supercharger in there and had a nos system. but those are the only things that ive heard. apparently he has every mod available. i dont have the slip anymore unfortunately, but ill get it. im movin back to WI soon so i have to do it quick. here are some of the mods to my bike: i just put on a new chain about 500 miles ago.Just put in a new battery about 3 months ago. The bike still has the factory installed clutch. 1397 ccâ€™s, 12.5 wiseco pistons, The big web cams, Ported head, New valve springs and retainers (better than stock), Modified air box with 4 short stacks, Power commander, Yosh exhaust with a ti-can. thats bout it.
