This is what I've done to it so far, cleaned carbs 3 times meticulously. Changed Gus synced it the best I could. When I take off hard in 1st and 2nd it jumps like it shuts off then on. Crazy. The other thing is I have other bikes that run great they r a 05 thundercat and a 94 cbr f2. The 01 r6 is the only one that has all the sync hoses connected to one another. R all these r6's like this. I'm thinking maybe this is the real problem. Anyone can help I would be in ur dept. Thanks
It jerks violently as if it's getting shut off and on? Fuelling issues are usually more gentle, while ignition issues can be quite harsh.
