bike sputters after 5k rpms - April 24, 2010, 03:03 PM

Dont know if this has been covered but my friend owns a 2000 zx6r, with 10k on it.

I rode it after a while because he as been busy with school. I just wanted to get it warmed up. I took it out on the highway and it seems that power is dying. He rides it almost every week.

In first gear, i throttled hard, but it didnt pick up like i thought it would. All it did was sputter, I felt the engine shaking and loosing power, checked oil, it was fine. no overheating nothing. This did this in every gear after around 4-5k rpms Can it have anything to do with the carbs, maybe they need to be cleaned?

Also the bike shuts off when say im in fifth gear and I down shift two gears, it cuts out. Or say im in like 4th gear, come to a red light and it cuts off.

Any help is greatly appreciated. thanks.

could be dirty carbs, i would double check all the vacuum lines too. Did the problem just start or had it been stored and not ran for a while?

Carbs all day. Ethanol. Some refineries are putting more than they claim, to make matters worse. Learn to clean them yourself or take it in.

Seafoam doesn't clean well. They need to be taken apart and cleaned properly.

I tried seafoam when i searched for the problem. looks like ima have to take it apart and clean it all up. Is it a DIY for someone with little motorcycle knowledge. I have tools, But i just dont wanna mess anything up.

Heres the history behind the bike.

We bought before the big storm hit, the day before it hit. It was wrecked and the original owner wrecked it. The guy we bought it from was the 2nd owner and he had it stored in a garage at his college campus. We really dont know how long its been sitting but by the looks of it its been sitting awhile. The front rim was bent so no one really rode it besides us. Once i changed out the forks, radiator, rim, brakes and did all the necessary maintenance work we took it out.

And yesterday I took it out for a spin after my friend had been riding it for a month and I was disgusted because my gsxr rides alot better than his, and his has 30000 miles less than I do. So I told him not to ride it like that because it shuts off too.


I plan to do the carbs, but If its too hard, I know a shop that charges 75$ an hour for labor. How long does it take?

Boomboom above if he's still in biz will probably give you the best deal.

Dealerships tend to start at 5-600 to remove a set of carbs and clean them properly. It's not as easy as you'd think.

I'd check the all the vac lines going to the air box just to make sure before pulling the carbs, but if it has been sitting awhile then the carbs are probably clogged up. If you have any machanical know how the carbs are not very bad to do. here is a link with pics on cleaning them http://www.kawiforums.com/zzr600-zx-...up-w-pics.html
