Both engines have a little over a gallon in them. SHOULD I LOSE ANY OF THE HEAD SHIMS? WHAT ARE YOUR THOUGHTS ON THE CARB INSERTS?

Thanks ahead of time for your help with this.

You could even go to a 6.5 in the buggy and would still have plenty of poke i found the 7 in my old agama to much and truggy i've only ran a 7 and it's got plenty of talk and top end and fuel economy is great with both
