If you take those silly chrome covers off the head, and throw them down the deepest hole you can find,... maintenance becomes much easier...
... and swapping to a Raptor petcock (see Tech section, "Test your petcock")... the tank comes off in 2 minutes... (it's even easy with the stock pet, once you master just where, when, and what, needs to wiggle)... (first time, 45 minutes, busted knuckles and and some frame scratches.... second time, 30 seconds...
...and, probably still one frame scratch)...
...
4k miles valve adjustment... (I go 6 or 8k)...
... and my spark plug may be 20k old... (I only changed it once, because I was bored)...
This an easy bike to care for... maybe the easiest one made in the past 25 years...
...(that's one of the main reasons I bought one,... I'm a lazy, forgetful, no good, maintainer)...
