valve procedure

Do I have to take off the gas tank, fuel line etc in order to adjust the valves? Or can I adjust them without taking anything off?

THANKS

Yup you have to take off the tank and every thing in the way of the top of the motor.

Yep, that tank is coming off if you want to adjust those valves. You will need a really smalle wrench to adjust them. Instead of spending the money on the "proper" tool to adjust the valves on the 300, I found that a deck screw that takes the square drive bit will fit perfect onto the adjuster, just put the screw into a pair of vise grips and use a wrench to loosen/tighted the lock nut. It should be a breeze.
