About two weeks ago I started getting a noise from my gearbox/ clutch. It only happens in gear 1 when I pull off from a complete stop. It sounds like a midget with a sledgehammer knocking the inside of the gearbox once and only once. It doesn't happen ever time I pull off but probably about 50% of the time. I have not heard this switching gears or at any other time when riding.
Any ideas what it might be? Is it worth me opening her up and taking a good look around the clutch/gearbox?
Sounds like a tight spot in the chain and adjustment, worn front sproket, worn slider at the outside.
So that noise could be caused by the chain?! I'll have to check it as I already think I do have a tight area in my chain. So it probably isn't anything on the inside of her then. Any tips on how to reduce the wear on the chain slider on the rear swing arm? I'm on my second one in like 20000 miles. The one on there now could use being replaced soon.
