Worked on my build a little more today, between checking the football games. Taking my time and going pretty slow and deliberate with the whole thing. Tightening the stock exhaust pipe I felt that unpleasant feeling of the nut loosening as it stripped. I wasn't even tightening that hard. What crap bolts the Chinese make for these engines!
I ordered the engine hardware kit from SBP. Then I thought what the heck I'll get a few more things. The highly rated SBP Expansion chamber exhaust, Heavy duty air filter, fuel filter, better fuel petcock, NGK iridium plug and upgraded spark plug wire. Should be improvement over stock even without flow porting, which will come later. Next weekend should be a fun one!
