Another important tip,especially if your bike sits while you wait for shims.Soak the shims in oil for a few minutes before installing them.Also dip the rocker arm shafts in fresh oil before installing them.I also poured oil over the valves,rocker arms,and cams before reassembling.I feel it helps to keep things from being to dry at start up.

Great stuff @Gills, thanks. I've a way to go before my next valve check's due, but this may just help me summon up the courage to give it a try myself ;)

Excellent guide!  :821: Is there an easy way to get those side fairings off if you have engine bars?

Thought so! Ah well, I am sure it could be worse!

I kind of dread my next projects because I am installing Hepco Becker crash bars on mine later this week.

Some people have asked why I checked my valve clearances early,at 9000 miles.My bike struggled to maintain 70 mph up moderate hills, and in strong head winds.It was also breaking up above 6000 rpm.It was like the bike couldn't get enough air,or fuel starved.At one point I thought my coils maybe dying and not providing enough spark.As I was disassembling the bike,I checked all of these things per the service manual.Everything checked out.I didn't have CEL light either.All of my valve clearances were out of spec on the tight side.They are listed else where in this thread.My clearances are now .18mm intake and .28 exhaust.Next time I will set the exhaust at .30mm,the upper limit of the spec.This will allow for a little longer times between valve clearance checks.It will take me about 30,000 miles to make sure this will work as it has on my other bikes.

So, did getting the adjustment correct fix your running problems?

I've noticed a change in the running of my bike in that I have a hard time getting up to higher speeds (speed limit 75mph) and have been chasing this for a little bit now.

My change seemed to coincide with changing the rear tire to a Shinko 705 so most of my detective work has involved making sure chain slack is correct and the wheel is in straight, however this could be just a coincidence.
