Reply to "Grinding noise when shifting : syncs or clutch ?"

Def you want to measure the gap a mentioned by the team notes, that is less expensive to fix

However, just a thought for further investigation..as I went through a gearbox situation..

quote:
Everything is ok when cold, but when the temperature rises (after approx. 15 or 20 miles riding), the grinding noise comes back.

The thing with the synchros is that the inside when new has a special surface which has some roughness, so when sliding during gear shifting oil is kept to speed up the destination gear to avoild grinding. If the synch is rottet like mine where there is not enough "oil hold" to provide this service. When oil is cold it appears stiffer hence it provides the service but when hot it slips to much..I replaced all 5!
