5th gear jumping

<< < (4/5) > >>

Steris:
Ive had the engine out and stripped, selector forks aren't worn at all but the 3 dogs on the 4th/5th gear are, i have now fitted the gear train out of the CB350 twin. This has 5 dogs and looks much more robust and the dogs engage fully. Its all back up and running now and I've done a few hundred miles without any issues, so fingers crossed this has fixed the problem.  :D

McCabe-Thiele (Ted):
Wow pleased you sorted it interesting that you could fit CB350 twin parts.

florence:
yes, the gearboxes are almost identical and much easier to find.

Bryanj:
The centre selector is the same part number,
Did you use 350 outer selectors or 500 and is it just ratios yhat are different?

Steris:
Hi Bryanj

The outer selectors are as good as new so they are the original 500 ones. The centre fork is 350 as is the 4th/5th gear. The ratios are the same just the needle bearings on the ends are different.
