Whats up OldMiniBikes, just got into go-karts thanks to one of my buddies and the speed urge has hit. i currently have a predator hemi 6.5 on my kart and wanted to bump up the power to gain top speed which is rpm bases some what and gain some more punch or power. Currently only has the governor removed, OldMiniBikes "stage 2 kit", and an arc billet flywheel. I need some advice/opinions on the rest of the build. I want to run the black mamba cam with 26 lb springs, mill the head and run a billet rod. this is where it gets iffy because i can deck it a bunch and run alky/meth or deck it less and run pump gas, and I need to take off the head to take pop out measurements to make sure i dont run any valve to piston issues. im new to this whole small engine game and could use some advice. Thanks again
