I did check the lash on the others before the kids were allowed to ride. They were very tight as well. They are now a little too loose likely, they do make noticeable valve train noise now. I would rather have them loose right now than too tight. I'll get back in there in a few days and true it up. I set as best I could with my .006 feeler, but I really have a hard time bending my gauge in there to get an accurate feel. Any tips? seems like a crap design to me with those round access plugs.

I'm going to try a couple more times to get hold of the dealer before I blow them up on here. I expect them to send a new head at least, as well as give me a good explanation as to why my 125cc quads I bought have 110cc engines. I am pretty annoyed at that.

I never got around to fixing or even looking into the FNR issue. It's not a huge deal, it does stay in gear. I'm wondering if it just needs some miles on it to loosen up.

I really appreciate the help everyone!

Bent feelers help a lot. My Honda cruiser has the same set up with the access ports. Those engines come in multiple displacements, is that one marked 110ccm?

The best $20 or so that I spent for good flexible feeler gauges is right HERE
