To begin, I am soooo glad there is a forum like this. I already stayed up late last night reading numerous posts. My brother put together an old schwinn and cheap 66cc craigslist motor together over winter break. He can't stop talking about how much fun it is cruising around Corpus Christi, where he goes to school. Of course I want to build one now. I found this cruiser on craigslist here in town and I plan an picking up a cheap motor off CL down in phoenix next weekend. My first question is: what is the best way to get my cheapy motor to run well at 7000 ft of elevation. This is my bike and my brittany puppy in my messy kitchen. The bike is a Western Flyer.
