just changed my oil and filter, bike ran great before but after i changed both oil and filter the bike is hitting redline at 84mph on first gear. when i raced my buddy with a 600 he was ahead of me the enitre time by a bike, i added 3.5 quarts of oil BUT i added some oil additive which is suppose to help promote less friction. Can that be it? i used motorcycle 10-40 superior wet clutch protection oil and bought the filter from discount auto parts? need help the bike is an 07 1K RR with 1900 miles on it this was the first time i changed the oil on it!! please need help quick

 

I dont know if this helps, but I just got done reading that you should not put any additives in with your oil. It could affect the operation of the clutch.

 

Could be a slipping clutch, but 84 MPH is about right for the top end of first gear isn't it? Like dwschultzy said, don't use additives,onlyhigh qualitymotorcycle oil.

 

sounds like a case of 600 having a better rider? just teasing...

I was reading about additives not to long ago alsoand how they don't help that much? But i don't think they would cause the engine to spool up faster? That is controled by timing and everything right?

 

Sounds like a slipping clutch. What was the max speed in 1st before? If it was 85 then it doesnt make much difference. Have you beaten this 600 before?
If it feels slower and is running slower, your clutch is probably slipping. Get it into a higher gear and put a load on it, say at 50 in 4-5th gear.........can it and see if the RPM jumps with little or no acceleration of the bike. If so back off, go home and fix it before the clutch gets fried.

 

A no-friction additive kind of defeats the whole purpose of the clutch plates. You are probably slipping the whole way to some extent. I wouldn't use anything like that in the oil. There are plenty of threads here that recommend different types of oil, but I think everyone is in agreement that additives are not good for the clutch. You probably want to flush that out before any serious damage is done.

 

and your oil was suppose to be changed way before 1900 miles for the first time

 

Bike was hitting redline at 95 in first gear b4 and i would always destroy the 600 out of 20 times i race him i would beat him 20 times!!! gotta be the additive since this staryted happening once i but the additive on

 

If I were you, I'd drain that oil good. Put some new oil in there, WITHOUT any additives. If it still feels like it's slipping a bit, try one more change. And from now on, don't put any oil additives in lol.

 

Amen to that one lol
