Finished up the gearbox Thursday morning and road tested. Leaving the driveway and onto the road, could not get second gear then overran/skipped into third. Shut down and went through gears by rocking the bike. Back on the road, better this time. Put about 8 miles on her varying speeds up to about 50 MPH and copious gear shifting. Shifting did improve somewhat.
Scope of project:
Gearbox:
New Andover kit. Bearings and bushings/bushes except the gearshift bush in the inner cover. (Roller layshaft bearing shimmed to .007" end float.)
New 1st gear pinion set and 2nd gear pinion set. New sleeve gear.
New outer cover in lieu of machining for oil seals at Gearshift and K/S shafts.
Other than transferring the shift ratchet to the new cover, I left the assembly as is. The clearance at the ratchet spring looks good.
New gaskets from Andover kit.
Lucas Oil 75-90 in the gearbox.
Primary chain case:
New inner primary case.
5W 30 oil in primary case.
I did not adjust the primary chain, but it seems tight.
Any thoughts and/or direction is appreciated.
Thanks!
