08-09 Rear Wheel Spins At 8-9MPH, Even With Clutch Pulled In?
So I have two of the same gen R6 in my garage that I'm working on. One's a Orange 09, the other is a Silver 08, identical other than the color basically.
I did a chain replacement and post lowside quick inspection on the 09, afterwards ran the rear in 1st on a rear stand to check and make sure it was good. Right off the bat the wheel was spinning at 8-9mph on the speedo in first or second, even with the clutch pulled in. Thinking this might be due to clutch cable maladjustment as it usually is, I check it since that was the side that lowsided. Other than some rash marks on the cable bracket, nothing was off, tried releasing all tension, putting it full tension, no change.
Weird thing is, it doesn't die when put in gear on the ground, which normally when it's a maladjusted clutch cable this far gone (I mean normally if there's any clutch drag I can stop the wheel by hand, but in this case it's spinning at 8-9mph) kills the bike when thrown in gear.
Having two of the same bike basically at the same time, I was able to check it against a far better maintained and never downed one. Turns out, it does the exact same thing, and is in far better shape.
Is this just something this generation of R6 does? I've never had a bike in that does that. A little bit maybe from clutch stiction, but nowhere this fast. The fact that two of the same bike from two different people doing the exact same thing leads me leads me to believe this is just the design of the 08/09 R6.
