Default hi everyone, does anybody have any ideas for me?

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?

Try checking you intake gasket or vacuum leaks. I think you can still use the same motor but you might have to change the cylinder head...

If your plug was not tight it probably just backed out. If the threads are fine the head should be fine, however your cdi doesn't like to run w/o the plug grounded to the motor. It is possible that your cdi is damaged; typically they work or don't but there is no law that says it can't be damaged and still work poorly or intermitantly. did your plug electrode get closed/damaged. Start by checking that you have a fat spark by removing and holding against the head and rotating the motor. If you have a repeated fat spark then that is not your problem. You could also just replace the plug and see if that fixes the problem.

Sounds like your clutch is slipping. Pop off the cover, spray some brake cleaner on the pads and turn the flower nut in a couple of notches.
