Hi everyone. I built my first gas bike and joined the site about 3 months ago - minimal problems so far, and people here have been very helpful. Not really looking for help this time since I solved the problem myself and was able to cannibalize a working coil off one of my roommate's spare motors. Just wanted to say hi and relate my observations. The old (working) coil I put in was grimy and oily, while there was nothing visibly wrong with mine (which was officially declared dead by a voltage meter) all the connections were solid. The first time I started her with the new (old) one, she started with such power and IMMEDIATELY started to hum. I cranked the throttle and she squealed! What is notable about this was that prior to this, she took a bit more effort to start, and would perform sluggishly for the first block or so. I could rev the throttle to warm her up quicker, but if I did it too hard too soon she'd die. And now she's performing better than ever, right off the driveway! I guess it does make me curious though, does a condition like that cause performance/efficiency issues the whole time the bike is running, or just when it's 'warming up'? Was I wasting fuel before? It's a very noticeable difference in how it runs now; should I notice my tank taking me further? I guess I'll find out over the next week but I'd love to hear any input! Cheers!
