It was very easy to do. I also removed the sparky and air box lid.
I havent ran it yet, other than a short idle to make sure everything was ok.
It sounds alittle quiter, as far as valve noise goes, and it started just as good as before.
I will put some seat time on her tommorow night to see how it feels!!!

I am not the most comfortable person with taking the head off of a 4-stroke so do you think you could do a walk through on it that is a little more LAYMAN-oriented than Laz's?
I really want to do the mod this saturday when I get my quad but I dont feel comfortable with doing using laz's description.

Sure, no problem. I thought about it after I did it, I should have took pictures so I could do a step by step tech artical on it.

Its actually VERY easy to do.

Check back later tonight, and Ill have one writing up. Ill try to get some pictures of the more detailed things that need to be done.

I would really appreciate it if you could do that. Like I said I am bringing mine home tomorrow morning so I figure I can get the re-jet and the pea-shooter out and the cam mod all done before I take it out to run it on Sunday.

is this the correct MAIN jet? It is a Keihin 170 hex jet. It is 16.5mm long.
