2nd try at it

This is my second attempt at a motorized bike. I started with a electra frame than did some body work and paint to it. I got a set of triple tree chopper forks that I cut down for the right look for ride height. Than I welded a front motor mount to frame and mounted the motor so it would be nice and solid the motor I had was used and most of the mounting holes were stripped out and we having a huge problem with vibration loosing everything up. So I drilled and tapped the front mount bolts out to 8mm and welded a plate on the top of my mount so it would sandwich the motor and hold it steady. Than on to my next problems exhaust bolts stripped, tryed everything nothing worked good ended up buying a new head from jnmotors and making a adaptor for my exhaust which is off of a rm85 and getting a mikuni vm18 carb and 40mm intake I'm just breaking the motor in but before the new cylnder I hit 43.5 mph on gps speedo app.
