I've got a couple of issues, first I've been driving my bike all over the city. I've probably put 2000 miles on my first motor, but one day, one of the motor mounts broke. When I drilled it out and re-tapped it, it is just running like crap. but after I got the hole thing put back together I forgot to put the spark plug all the way in, and after a couple times around the block it shot out of the motor. Then I put it back right and now it definitely does not have the same pick up as it did. Any ideas? Second, I just got a jesse james chopper with a new motor on the way, any ideas how to mount the motor? I saw that motor mount on ebay for the schwinn chopper, do you think that will work?
