Ok, so I've noticed a small problem..... and want to bounce some ideas around.
Ever sense I went back to stock gearing on my 9R I have noticed a problem. In 4th gear and only in 4th gear at about 6K RPM if I WOT the bike the clutch will start to slip. Not in 1,2,3,5,6, just in 4th. Everything else it's just all power.
I changed the oil and filter just as a caution. I run Amsoil Full syn 10W-40. I spoke to the head guy at a Kawasaki dealer and he said they just spoke about this with the 10R at a Kawasaki cert. class. He said it is a matter of gearing vs power.
Allow me to TRY to explain like he did. For my bike and it's gearing right now, 4th gear at that RPM and at that speed. When I go WOT the motor wants to go and go now. But with the taller gear on the rear wheel and tranny it wants to slip slightly. Add in super slippery synthetic oil and you got slipage. It doesn't do it in 3rd because the gear is shorter and doesn't do it in 5th because it's so tall or I'm going so fast by then that there just isn't enough engine power to spin it.
We both figure that when I change the gearing the problem will probably want to migrate to a higher gear...maybe 5th. But that if it gets too high it may disappear completely due to dealing with higher and higher gearing.
This is all a mizture of 14K on the bike and synthetic oil. At least that is what we figured. But I'd like to hear some of your thought on it. Some of you have dealt plenty on slipping clutchs and stuff like that... so
a guy out.
He also suggested a "clutch test"... put the front wheel to a brick wall and in 2nd gear start to let the clutch out..slowly...don't pop it cause it will just want to spin the back tire...but slowly and if it don't start to free spin the motor, the clutch is fine.... any thoughts on that?
