All right I have spent the last week reading a whole lot of messages on this forum. I recently bought a 80cc motor from a guy in the local area. I initially found these motors on Ebay by mistake and was very intriqued. So I searched craigslist and found a local guy selling these motors. He seemed a little shady at first, but he showd me a bike that he installed a motor on (a classic beach cruiser) I was able to ride the guy's bike and I fell instantly in love. The misses won't let me get a motorcycle, so this is the next best thing and she is ok with it. I mounted my new motor on my old Nishiki Colorado that I purchased when I was in High School. This thing is a joke - Bright yellow and blue. It took me about 3 full hours to install this, the hardest part was the stupid sprocket on the rear wheel. Once I got it all together added the fuel(the whole mixing thing was extremely confusing, but I think I finally have it figured out) I broke the motor in according to how my salesman told me to do it, which is different than what anyone else here has posted so far that I have read. Well, to make a long story longer, I recently bought some new cruiser style handlebars to replace my flat bar mountain bike handlebars so that I can sit more upright, I took everthing off my bike, sanded her down and painted her primer black. The new handlebars required me to replace all the cables and outer covers which needed to be done anyhow. I bought a big comfy seat, which is sooo much better by the way, my "A" was killing me after a while on that old thin piece of crud. When I took the motor off the initial install, I put it on it's side and after an hour or so I noticed fuel pooled under it so i laid it upright then reinstalled it. after reinstallation, the bike all of a sudden wouldn't go up hill, Just took the intake off and notice it had 1/2 of the gasket. I cut a new one out of the thick hard cardboard everyone has been talking about and used some sealant that I bought at Pepboys. I also bought some gasket material but elected not to use it because I remembered reading something about not using ruberized gasket material(I wished I had read that before I bought it) Oh well, I should have it put together in the morning to test out my new cardboard gasket. If you are still reading this, you are a better person that I am. When I get some time, I will try to post a Pick of my new ride. It is a blast! Hopefully this makes sense, because I am not going to go back and proofread this one for errors.
