My bike has started to "stick" in gear, I'll be in 3rd/4th and will not be able to change up/down. Happening in all gears (but mostly the higher gears ie 3/4). So I had the mechanic take a look, I thought the clutch, wasn't disengaging or needed fettling. He says the clutch is fine and it's likely to be some spring or similar in the release of gears.
Anyone got an idea on this? I imagine mechanic would have the engine out to even be able to check/assess, and sure at that stage it's into big money?
Is there a simple thing to check (outside of clutch adjustment)?
Is it a big job to assess engine gear system?
Engine out?
Anything you folks can offer that I could pass on to the spanner wielder, I'd be grateful.
On restoration of my 83 Aspencade that sat for 13 years, the maiden run it got stuck in 4th at a light, uphill with cars behind me. The advice I got here was the clutch plates were sticking and to do a treatment of marvel mystery oil, drain out 1 qt oil and replace with MMO, ride @200 miles, one ride, low rpms (2500-3000), lots of shifting up and down through the lower gears first then progress upward 1 gear then back down to first a few times until that gear is smooth shifting. Then go home and change the oil and filter while its still hot to remove all the gunk that the MMO loosens up. Use Rotella or Delo 15w40 oil for smooth shifts.
It takes time to loosen it up again from a long sleep, if that is your bikes case.
This will also clean out the gunk in the cases and pickup screens for the oil pumps.
