I just saw where your from and had to toss this lil tidbit in here Evel Knievel was my brothers and my Idol growing up as kids.
When my parents bought me a pleather Evel Knievel jacket. I was jumping every kids Big Wheel & Green Machine in the neighbor hood on my 1970's Huffy All-Pro Muscle Bike with a Banana Seat & a sissy bar and a 10' fiber glass pole with a neon orange flag on it
Here is a similar bike to my huffy
One other issue I had with my bike i9n the beginning was my gas tank was not venting properly & it wouldn't start or run after a while. However it would run at first then die out & thats not what your dealing with >
I haVE A QUESTION DID YOUR MOTOR COME COMPLETELY BUILT OR DID YOU HAVE TO PUT THE HEAD ON YOURSELF?
