Hi guys,
I own a 2011 Suzuki RMZ 250 which I recently bought. It is virtually impossible to start by kicking it and it is very hard to start by kick when the engine is hot. If I push it down the hill, no problem starting. That’s why I decided to check the valves and adjust the clearance. One of the intake valves measured at 0 mm clearance. The shim that was in there was 1.30 mm and I put a 1.20 mm one. However I am still measuring 0 mm clearance. What do you guys think it is going on? 1.20 mm is the smallest shim in the kit I got. Does this mean that the valve is bad and needs to be replaced or even something worst is going on?
Thank you!

new valves, new seats, new springs, new valve seals, new retainers and new clips.
I would further suggest replacing the cam chain with new as well as the piston and rings.

A complete valve job would mean all four valves regardless of the condition of the rest, correct?
Also what brand parts do you recommend or should I go with OEM?
Thanks again!
When you do a valve job, it is best to do them all at one time. Be sure that the person doing the job knows his stuff for a good job.

Typically you want a shop to do this because theres special machinery required to do a good job.
Thanks again guys. This was very helpful.
Even if his valve is trashed, the seat is probably in a similar condition. The seat at minimum needs recut and valves need replaced. If youre at the point where the margin is gone and its mushroomed over you might as well do it all up right. The cost of new seats is likely the same as buying the seat cutter and guide.
