I only have problems when I'm sitting on an incline pointed up hill when the bike is warm.
I have not tried to adjust the clutch cable yet.
My driveway in front of the garage is a small incline, not much at really, I get neutral no problem riding the bike around town, even at the red light about 4 blocks from the house (where the road is level). But when I pull up to the garage door (on the slight incline) and try to get neutral to keep from turning the motor off while I get off and open the garage door, I can’t get it for anything. Revving the motor, rolling forward or back, easing out on the clutch till it grabs a little or a lot, no dice, I ALWAYS have to turn it off then crank it again for the 15 foot drive into the garage.
