Julian Posted August 16, 2021 Share Posted August 16, 2021 I need to clean my chain soon, and this time I would also like to clean the front sprocket thoroughly. I know that I need to get the shifter lever out of the way, but I haven't found any clear instructions. If I peel back the rubber cover pictured and undo that nut, it looks like I will then have access to remove sprocket cover, is that correct? When I reaatach the shifter lever the same way, are there any adjustments needed or possible problems? Thanks. Link to comment Share on other sites More sharing options...
Triple Jim Posted August 16, 2021 Share Posted August 16, 2021 (edited) I'd take out the bolt that attaches the lever to the transmission shaft and pull the whole assembly out of the way. Mark the transmission shaft at the split in the lever to you can get it back on in the same position without fiddling. edit: I see a faint line in the end of the shaft that lines up with the split, so it appears to be pre-marked for you.

Jim, I did not understand a single word you said What is "the whole assembly" and why do I need to pull it out? I'm trying to keep things simple, won't undoing that nut do the job?

Triple Jim Posted August 16, 2021 Share Posted August 16, 2021 There is one bolt that holds the black lever to the shaft that's coming out of the transmission. If you remove that, you can move the assembly (rod, adjuster, lever, boot, etc.) out of the way, and it won't mess up any adjustments. Link to comment Share on other sites More sharing options...
klx678 Posted August 16, 2021 Share Posted August 16, 2021 Absolutely agree, loosen and remove the clamp bolt holding the shifter on the splined shaft, then slide it off and swing it out of the way. If there's no mark, get a sharpie and make one so you know exactly where it should slide back on the splined shaft. Link to comment Share on other sites More sharing options...
7fold Posted August 16, 2021 Share Posted August 16, 2021 If you're still confused, all you need to do is make a mark where the blue circle is (but it looks like it's already marked) and loosed the one bolt circled in red. Once you loosen that clamp bolt, the whole arm will slide off leaving you plenty of room to loosen the bolts holding the plastic sprocket cover on and remove it completely. 1 Link to comment Share on other sites More sharing options...
Julian Posted August 17, 2021 Author Share Posted August 17, 2021 Thank you, does that bolt need to be tightened at a certain torque after, or use common sense? Link to comment Share on other sites More sharing options...

I'm sure there's a specific torque value if you search hard enough, but I just make sure it's tight and give it maybe an extra quarter turn. I haven't had any issues with it coming loose. You can get a feel for how tight it was from the factory as you crack it loose - it wasn't super tight to begin with. 1 Link to comment Share on other sites More sharing options...

The manual says the shift arm pinch bolt torque value is 10 ft-lbs (but common sense should also work). 1 Link to comment Share on other sites More sharing options...

Julian Posted August 23, 2021 Author Share Posted August 23, 2021 I took out the lever assembly and put it back together without incident. I'm sure glad I did it, the plastic rail guide and the inside of the cover were absolutely filthy! If you haven't opened yours in a while maybe have a look Link to comment Share on other sites More sharing options...
Triple Jim Posted August 23, 2021 Share Posted August 23, 2021 Don't feel too bad... that's perfectly normal unless you clean it after every ride. 1 Link to comment Share on other sites More sharing options...
klx678 Posted August 23, 2021 Share Posted August 23, 2021 Not sure without a closer look, but that sprocket looks about due for replacement, it's losing the symmetry of the U, hooking. You may want to check how the rear and chain are. Pull the chain away from the rear sprocket at the back (3:00 o'clock). This is worn out: this is not: Link to comment Share on other sites More sharing options...

mossrider Posted August 23, 2021 Share Posted August 23, 2021 It's fine. Look at the bottom pic, it's straight on to the 3-6 o'clock portion of the teeth. Run the hell out of it. Link to comment Share on other sites More sharing options...
