Having put more than 100K on 2 800 classics, the shims do not wear significantly. On all specified changes, i think I need 2 shim swaps pver all the miles. I used synth oil. Happy wrenching!

No adjusting screws unfortunately. I purchased a Hot Cams "shim kit refill pack" 9.48mm O.D. x 2.10mm - 2.35mm containing 5 of each size. It worked well for me.

6000 miles

I'm afraid I am not familiar with that motorcycle. Although there will be similarities shared amongst all OHC V-twins, the process will not match exactly, and the specifications for the 400 will almost certainly be different. Should you attempt a valve adjustment, I predict that with a little knowledge you shouldn't have too much trouble.

too low of clearance can lead to the valves staying open and letting hot combustion gasses by, which will lead to your head melting away. Too high of clearence can lead to excessive wear due to the speed of things being a sort of ramp up and ramp down thing, the bigger the gap the faster things are moving once they come into contact.

No, unless you bust them accidentally. They are very thick rubber gaskets on the head cover. Happy wrenching!

Adjusting valve clearances is periodic maintenance. There are various symptoms and consequences of improperly adjusted valves, not excluding engine damage.

For your valve cover gaskets yes. Why do yours need replacement?

@@lycogala1843 oil leak.

@@dan1769 I'd first check to make sure it's not coming from one of the lines going into the air cleaner box, that's a pretty common spot for oil to leak on these. Also make sure you've emptied the little oil catch bottle near the bottom of your rad.

@@lycogala1843 Thanks...I will.

U don't have to on many hikes u just have to be willing and mechanically inclined enough it's not too hard

He didn't pull the cams or buckets or shims. He only did about 1/2 the work, video should be named how to measure valves and shims

The bike did not come this way from the factory. The valve clearances would have been in spec. Valves open and close thousands of times per minute and slowly beat themselves further into their seats, tightening clearances. Some engines are more prone to this type of wear, the 800 being a good example. It's not uncommon to see relatively low mileage 800s with engine damage due to this. More modern valvetrain designs, including those which have been used in car and truck engines for a long time now, do not require adjustment.

@@lycogala1843 You never had an engine that was not in spec from the factory. I have had several. You are 100% correct on the rest of the statement and the video was nicely done. Thank You.
