valve adjustment

[trx400exat05]

is a valve adjusting a hard maintance thing or would it be better to take to like a local shop and have it done?? is it expensive?? and also how do u know if a 400ex needs it?? mine is ticking very loudly

Valve adjustments are very easy. Grab a manual and have at it. It takes longer to remove the gas tank than to adjust the valves.

they make a speical tool to do adjustment not sure were you can get it

There's not a special tool needed. Once the covers are off and the engine is at TDC, a 10mm wrench, flat head screw driver, and feeler gauges are the only tools needed.

What's the needle nose for?

The flathead screw driver is used for the actual adjustment.

you need allen wrneches to get the 2 covers off 2...i think one is a 5 mm and the other is a 10 mm or 8 mm not sure which...

this is what i used to do it the first time..pretty simple really...
