I am rebuilding my daughters DRR DRX90. This is a 2006 model. I installed new crank bearings and seals, new cylinder, piston, rings, and gaskets. Also I picked up a high compression head. My question is, with this all togethor I have a compression reading of 210 psi. Will this motor stay togethor with a 50/50 mix of 110 race fuel and 93 octane? My premix is 32:1 with Klotz Supertechniplate. I just want to be sure the compression won't be too high. Thanks for your help.
