Pro Gear Box Gremlin

Featured Replies

Just wondering if there is a known problem with Pro G/boxes jumping into gear? Mines jumped in a couple of times now, just after starting, is it a symptom of something about to let go or 'they all do that sir'? Running recommended dextron III ATF oil.

Ta muchly.

Does the bike also shift hard in some gears as well. For instance, it hard to get into second - or maybe it upshifts into 2nd OK, but hard to down shift form 3rd?? If so, it's possible you just need to adjust the eccentric preload adjuster on the shift shaft. If you watch the engine repair video on the trials parts USA site, it will show you how to do it. There was a recent shifting thread that had the exact info on the video.

I can't say I've noticed any other symptoms thankfully. I'll have a gander at the video though.

Great vid, I didn't know that about the sharper edge on a circlip, makes complete sense. I'll check for the gear lever click thing, good stuff.
