Has anyone played around with compression heights on their engines? my rtr 8ight came with .014" worth of shims making the compression height .040" i removed one shim bringing it down to .031" I will be testing it as soon as my new clutch bell comes in. i feel like the stock gearing is way too tall at 17/52. most race buggies seem to 13/48 ish range it seems like to me. i ordered a 15tooth bell so my new ratio will be 3.71:1 which is a lot closer to the 3.69:1 a 13/48 set up would give you. Anyway, any experiences anyone has had with changing compression height of your engines would be greatly helpful and interesting to read
