Head mod squish adjustment machining USA
 
Can I get a recommendation for someone in the US to modify the stock head?
I used rb-designs for another gasgas, but he is retired.
It is for an ec200

RK-TEK my new head for my GP just showed up today in the mail! Hoping to get some testing done this weekend. 2strokeheads.com

I went with an RK-TEK head as well on my 18 300. The bike runs much better with it now. Before it was a little finicky with jetting and had some slight detonation here and there. The bike sounds different now. Super crisp.

I don't have the CDI remap done yet but plan to get it done. It feels like it added a little boost from bottom to top. I can run third where I used to downshift to 2nd. It revs out better now as well.

I just got my 84 RM 250 head back from Pro-Circuit, it looks awesome but I have not reassembled my engine yet.
