Gearbox pitting advice

Post by mserifov » Sun Jan 20, 2019 4:59 am

Hello to all,

I am in process of restoring Yamaha XT600 34L 1983 and upgrade on the level of good bike for TET travel and some trips on midle East.

My big issue is gear box of 34L. So I post question what is best solution for durable strong 34L transmison.

I know that separate oil feed to 5th gear help and 3AJ oil pump. And I did make that upgrades.

But I still need to change 5th gears, and by reading online forums some people recomend XTZ 660 gearbox upgrade.

Any advice is more then welcome.
