Yesterday I rode about an hour with no problems. I put a new chain on and threaded it by cutting the old one and zip tying the new one to it and feeding it on.
This morning when I started my bike the neutral light did not come on and the bike made a slight clicking as I backed her out of the garage. She clicked down into first no problem but as I headed out I could not shift into second no matter how I worked the clutch or shifter and the neutral light never came on.
No, infact I didn't change the sprockets as they are in good shape (2nd countershaft and 3rd rear). When I fed the new chain through could the zip tie have hit and disconnected something near the countershaft sprocket?
When I get home the first thing I'll do is recheck the chain slack and pull the cover.
Hmm... I don't think a disconnected/dirty/faulty neutral sensor or speed sensor would affect it that way.
Is your shifter operating normally without sticking? You probably have a bent or broken shift fork.
