Re: Can't get the cylinder head cover off...

The charred look is just a carbon build up. Yup, the head looks some warped. Let the machine shop at er.

Alright, hopefully they fix it! and hopefully they can check the valves too because it's like 2 days work to take the thing apart! So I don't want to have to redo anything haha

We have our fingers crossed for a successful fix.

Is the carbon build up bad?

I don't know how this is happening either... especially wrenching from a supposed industry "mechanic".

I just pulled the top end off my wife's GZ to replace the valve seals, and setting the valve clearences a fairly straight forward procedure. Suzuki is one of the most user friendly valvetrains to set valve lash. Most other mfg's use precision shims under the cam to adjust, and this shim method is expensive and a PIA !

1. you nead to remove the head gasket to check the head
2. is better to use a metal straight edge

Only time I ever seen this is when the valves sink into the seats & you can't get any clearance to adjust.This is not common & was a problem on Kawasaki twin's from not adjusting the valves & they just keep getting tighter & tighter till the bike wouldn't start.

Re: Can't get the cylinder head cover off...

I took off the head gasket and used the wooden end of the ruler, and apparently the metal end isn't that straight because the wooden end seemed to be pretty flush with the head all the way around

They will check it before they plane it,so they know how much to remove to make it flat.
