Hey guys/gals, Just finishing up a complete rebuild of a 2000 426 I bought from a friend. So far so good, as the entire project has come together very nicely. I have replaced every single bearing on the bike chasis, wheels, painted the frame. Rebuilt the forks and rear shock. New piston, rings, timing chain, completely fresh valve train, hot cams exhaust cam. While I was getting the new guides pressed, I ended up porting and polishing the head. Dismanteled and cleaned the carb, did the BK mod. So far, so good. The bike absolutely tears at any RPM range. Now this brings me to my question... When I was putting the front sprocket back on, I noticed that the drive axle was quite stiff to turn by hand once the sprocket nut was tightened down any more than hand tight. Once I put the chain on, it was fairly easy to turn by spinning the rear wheel (as you would expect), but you could still feel some tension. Is this normal? Forgive me for asking this question if it seems a little on the dumb side, but after spending 11 years on the sportbike side of the world, this is the first time I have felt any "tension" in a countershaft with the sprocket torqued properly, and bike in neutral. Thanks for your help, and thanks for having such an awesome forum that has already helped me SSSSOOOO many times on this project. I love the search feature... hence only a few posts so far.
