Also no need to grind down a good wrench. You can unscrew the cover mounting stud, that will give you plenty of working room. Just dont over tighten when you put it back on.
If you warm up your engine, then adjust your pushrods until they are difficult to turn with your fingers you will have quiet valves. I got this little tip from a RE website (I forget which one) and my bike has run quietly for the last 3700 miles with no need for an adjustment. The bike usually starts first kick, without choke, and runs great getting 100 MPG. Dew.
That website that tells a great deal about setting the valves is Cybersteering.com..........its and India site is is great to read the indepth stuff about our bikes.........dg
That Cybersteering.com covers a lot of territory. Could you refer me to the specific section that explains the valve adjustment?
