2005 Busa Not Starting

Jonathan Burton

I've finally given up before I break something in fustration. Bike was running fine a couple of days ago. Now it fires and rumbles but wont start. I tried the usual trouble shoots, battery was fine even tried with jumper cables. I replaced spark plugs with new ones. Now Im cleaning the fuel pump.

Previous owner said he had a power commander installed but after stripping everything down he either had it removed or hid it in the devils arse because I cant find it anywhere. Ive read that they can cause engine malfunctions so I thought Id throw that out there.

The bike started fine until after I changed the clutch and break levers. I also switched gas from 91 to 87 after reading 87 is better for 1st gen busas. After these two changes I checked the bike and it started. Now, 2 days later, it does not. Hope this is enough info to get the ball rolling. Any and all help is greatly, GREATLY appreciated.

Put the stock clutch lever back on and see if the problem is still there. There may be a contact or switch issue with the new levers.

Can you squirt some fuel down the throttle bodies? Have you checked for a spark? Any codes in dealer mode? There is a gear selection switch behind the clutch, not sure if a damaged wire could cause you're problem though.
I know that busas run a little rich but I would have thought higher octane would be better than lower?
Check the basics, spark and fuel.


is it completely dead ? or does it turn over and rumbles ?
Id have a good look at fuel pressure , the filter is notorious for creating issues , there is a good write up on the site for this.


Did you check the fuses under the left black plastic cover from gastank to side fairing. there is a fuse in there that I blew the thing ran great one min jumped back on to start it and take it for a ride and all it did would crank. I was like WTF.. Bam blown fuse
