My First Motorized Bike ( Friction Driven )

Here is my friction driven bike me and my dad built over the course of a week, all info can be found in the General Discussion Section under "Motorized Bike Build". The Engine is 30CC Ryobi Weed Wacker engine and it goes so well, about 25-30mph. The spindle is 1 1/4 inches in diameter and was made on the lathe by a friend of my dads. So here's the pics, enjoy!

First Run!!!!

haha, well i gave it a test run and it goes pretty good, i have to tune the High on the carby a bit more but it was a lil wet so the spindle was slipping so i didnt get it to top speed, with the spindle wet i got it to about 40km/h which is like 25mph so wen its dry it should go pretty darn quick I no ur not suppose to ride in the wet as it wrecks the tyre but my dad said if it stuffs up he will buy me a new one so im like ok and rode it haha. It sounds awesome and is such a cool feeling to ride around the place, like a mini motor bike.

Here's the link to the video:

u can raise and lower the mount but i never do. When i want to ride normally i take the spark plug out so its not hard to pedal.
