I have a sport engine and I have a tuned head and button can someone tell me the correct size head shims I should be using. The tuned engine I got the head from had a copper .11 and a silver .36 is this correct. The instructions just show 1 shim. Thanks in advance

The copper shim is 0.1mm and the aluminum shim is 0.3mm, If you want to play it safe you use 1 copper and 1 alu shim, however the engine will have a little more punch when using 1 alu shim of 0.3mm

I have a GRP tuned .21 with the GRP exhaust that has maybe 2 gallons through it. If I were to Sell it. What is a price that some of you would take a grab at

Can someone give me the needle settings for the grp when raced tuned. I know they won't be exactly the same but it should be in the ball park. Thanks for any info.

LSN .045 above flush
Idle .030 from flush
