I am on here for a friend that is having some irritating problems with his 2002 busa. He has to crank and crank his bike to start it. It starts quicker if he turns on his fast idler. He also has a studder at wot around 6000-7000rpms, but if he rolls off a bit it will pull out of it. He has a tre, K&N, full yosh trs system and a pc3usb (that has been disconnected until we figure out the problem). I have read on here a few things that I am going to have to check out for him this weekend. It looks like I need to sync his tps, find someone to sync his tb's, check his fuel pump/filter(it doesn't have a steady hum when you start the bike, it kind of oscillates), clean his tb's. Anything else? I am kind of starting this thread just to let everyone know our progress. He has lived with this problem for awhile and was furious to the point of selling it (luckily the guy backed out). All of the shops here in southern Indiana have a 3 week waiting list for service and we are leaving to go to deals gap next Tuesday. I hope I can have this resolved by then.
Thank you for any help,
Logan
