just wondering on my 07 yfz i've probably put 50-70 hours on it so far and i've pulled the top off and checked my cam and tappet clearence and it has not changed at all and i was told that it would have to be adjusted but i was just wondering if anyone has had to adjust your right away or no...... thanks

 

I have a service for my '05... doubt its different for your '07.

intake = 0.1-0.15 mm
exh = 0.2-0.25 mm

it recommends first month... then every 6months after that... not sure what that means in hrs. but they recommend the same for the engine oil and i change every 20hrs.

I've heard that you don't need to check the timing as often as they recommend as well
