I did a double take...260k on a monster 900...I'm on my way...Ive got 30k on my 821...22k the first year but i lost the entire summer to this valve problem the following year and only achieved 8k miles more. Now, with two engines 3 sets of heads there is little to hold me back....but its the valves...i laugh when i read about people bickering about the adjustment...frankly if it can make it another 18k miles without tripping the check engine light because of a dead valve i would be amazed...and if it didn't i would still swap in a new head anyway just to save myself from a surprise...But this is running the engine hard...I know valve jobs aren't made up but haven't found much of any mention to it...I adjusted the valves...then 5k miles later i adjusted them again and when the check engine light came back on the third time there was no more adjustment to be made...everything was in spec... and I could see by the carbon build up in the port that the exhaust valves have stopped sealing...a tear-down was the only fix...i still have the initial exhaust valves, they're pitted pretty good but might clean up with a wire wheel and lap in just fine, not sure how many times i can do this but feel comfortable they wont make it another 20k miles without trouble...It just came a lot quicker than I imagined...granted I alson tought my first set of tires could last 20k miles...I was hit with reality accordingly and have moved on since...this is the most recent slap to the face...but aside from riding it like i'm qualifying for a starting grid position...how am I alone on this....because this to me is the cost of maintenance i would expect to hear about...valve adjustments are essentially free in comparison...
