Trenton Tigney Posted September 25, 2013 Author Report Share Posted September 25, 2013 What does head lights haft to do with power ratio? An the chain is stock length an gearing is bumped up one notch for more speed. Tire pressure id haft to check , but pretty sure it's standard pressure the maxxis tire calls for that's on it.

#1JUANstunna Posted September 25, 2013 Report Share Posted September 25, 2013 Yes I had a machine shop port an polish it Scares me that you had a "machine shop port and polish it". Best of luck. This thing will have between 35-95hp. Quote Link to comment Share on other sites More sharing options...
Trenton Tigney Posted September 25, 2013 Author Report Share Posted September 25, 2013 It's just not any ordinary machine shop I should have mentioned. They specialize in rebuilding porting engines for racing. They have there own engines they do an race. Quote Link to comment Share on other sites More sharing options...
