New from SoCal working on 3rd build in 2 weeks

Hello, New here from Hemet Ca. Just wanted to say hi and share a few builds.
We bought a new Echo weed wacker a few weeks ago and I had the old homelite just needing a purpose. It would hardly run. I found the stupid spark arrestor (small screen over exhaust holes) was clogged. Removed the screen and it fired right up. So after a few hours of research we went to work. I haven't spent any money so far.
We used fish tank air tubing for fuel lines and a Craftsman socket for the drive spindle. I was skeptical if it would work much less stay together. Man this thing rips. Maybe 20 plus MPH. We have run 2 tanks of gas through it so far with very little adjustments.
The pull starter has to be scrapped to attatch the drive so starting is a snap. Just get on and give it a few spins on the pedals and it fires up and accelerates. We still need a longer throttle cable but for zero dollars we have a Motorcycle. Lol. Too much fun!

The girls bike above is the one I am trying to fit the chainsaw motor to. So far I am stuck. The weedeater motors were easy. The exhaust is facing forward on this one. Considering scrapping the clutch and going direct.

Cool, looks good. Can you route the exhaust around, down and back or is there no space to work it out that way?

I dunno. Do you mean like a pipe?

Yeah, that's what I was thinking.. Granted, I know nothing about the layout you're working with on the motor or the bike, but there's bound to be a way to work it out. What have you got on the motor's exhaust port in terms of mounting hardware? (studs/bolts, or...?)
