whats wrong bike runs fine shifts fine but smokes like a bug fogger is this worth 300.00 shipped i have a great running motor on mine but my 4th gear is out

 

the bike for $300? yea Id jump on that.

 

my bad just motor

 

fouled plug could make it misfire which would make it smoke. A/F ratio is wrong (which could cause a fouled plug as well).

 

shipped to you for $300 though still isnt bad. If i had the cash I would jump on it. hell worst case scenario you have to put some ring and bearings in her, and maybe a valve job. I wish I could find a spare engine to build up the way I wanted to.. She would be MEAN, some honda racing cams, head work, maybe a big bore kit. undercut gears in the tranny. I wish.
