I need to tap the general collective on shimming valves. I am at 15,000 miles and doing my valve adjustments. The exhaust were all at .2 so I shimmed them back to where they should be. The intake valves are all about .127, should I adjust them as well or call it good and start bolting it all back together? How likely are they to tighten and I end up wishing I had done them as well as long as I had the bike apart?
