Hi all! 2005 DRZ400S (just converted to SM), got bike with 5500km (3400mi), bike now has ~7200km (~4500mi) I ride 100% street, previous owner took the bike off road. I was looking over the bike today and noticed that the countershaft sprocket nut was loose! If it wasn't for the bent washer!... I think last time I checked the countershaft nut was like ~800km-1000km ago (500mi-600mi)... Followed instructions from FAQ for locktite fix. Flattened the washer and removed nut, washer, sprocket (which turned out to be a sunstar 14T), retainer, spacer and O ring. Cleaned the countershaft. The O ring and the spacer appear to be OK, cleaned them and reinstalled. Countershaft turns (by hand) freely, seems to be OK... Sprocket has a tiny bit of play on the countershaft, is it OK, or does it have to be tight? It looks like I need a new washer. Should I replace the nut as well? Just read this posted by E Marquez http://www.thumpertalk.com/topic/213275-another-2nd-gear-bushing-dies-in-place/?p=1674296 Is my transmission gonna lock up in future, as Eddie Sisneros mentions in that thread, even after doing loctite fix? Does it just lock up completely while riding, or it happens gradually? What symptoms should I watch for, down the road? Thanks guys! PS Will going to 15/41 from 14/41 make a difference, speed/acceleration wise?
