Just a thought, have you tried putting the bike on the center-stand, starting it up, put it in gear, and letting the clutch lever out?
x2 but..
After some research, I guess I'm going to do an oil change with 20w50 oil...then let the bike warm up, and the rear wheel spin a bit(if I can get it off the ground, no center stand)...
Then I'll try to drive it again.
Anyone have thoughts?
So..
It rolls freely in neutral,
it will not roll freely in gear,
it will start in gear with the clutch lever pulled in,
it does not lurch when you start in gear,
it will shift into gear but stall when you try to ride off,
and there are no weird sounds except for a little rattling (normal I do believe)..
Have you tried adjusting the clutch yet? But I'm not
too sure the clutch is the issue.
If the clutch were sticking (staying engaged) it would lurch when started in gear.
If the clutch were sticking (staying disengaged) it would not stall, the engine would simply rev or the clutch would slip.
So I would think it's internal (but no weird clunks, grinding, or other sounds), or it's a fuel or ignition issue.
So maybe jack up the rear and run it through all the gears. If it does, then it's most likely not an internal trans issue.
And regardless of the the clutch safety switch wiring, it should make no difference once the bike is started. It will not inhibit you from riding or cause stalling, it would only (possibly) cause starting issues. Though my wires have been disconnected for the last three months and it starts perfectly fine.
I'm telling you though, if you have a fuel starvation issue or weak spark, the bike will idle all day long (provided you have fuel in the tank) and everything will seem fine. But, when you try to ride off under load you'll get stalling and/ or sputtering. The only thing is, is that running through the gears with the rear tire of the ground doesn't necessarily rule this out as the rear wheel is spinning freely under no load. Just more food for thought
