Ditch the idler!!!
Due to a broken rear stud I had to pull my engine tonight and replace it with a spare that came with my kit. The spare was shorter so I had to remove one of my 5/16" shims and do a little fiddling with my engine placement. Went to put the chain on and lo and behold I found out I could take out a full link, ditch the idler and the fit would be perfect. Couldn't believe it, just rolling the bike around to check the rear sprocket alignment there was hardly any drag at all anymore. Had to do a little hammer and drift through the spokes clearance work to the lower frame rail to get rid of a slight chain rub though. Went out for a 20 mile right tonight and I can't believe the difference, she's quieter there's way less vibration and a little more top end.
Now if I could only get my gas cap to stop buzzing, never noticed it before but man is it annoying! lol
