Trenton Tigney Posted September 25, 2013 Author Report Posted September 25, 2013 You need all that just for horse power rating? Quote
Coupelx Posted September 25, 2013 Report Posted September 25, 2013 4mil crank in a stock stroke cylinder...... Quote
fappy'97 Posted September 25, 2013 Report Posted September 25, 2013 You need all that just for horse power rating? Yes, absolutely. Quote
Trenton Tigney Posted September 25, 2013 Author Report 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. Quote
Trenton Tigney Posted September 25, 2013 Author Report Posted September 25, 2013 4mil crank in a stock stroke cylinder...... Yes Quote

#1JUANstunna Posted September 25, 2013 Report 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
Trenton Tigney Posted September 25, 2013 Author Report 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
