Hey Key, The build looks great. Been awhile since Ive been on this site. I ended up using my 2.5 on a go kart for my girlfriends 7 yr. old. I degoverned it and it really hauls *** once up to speed. Slow on take off with me on it but thats because theres no assist. On a bike, a couple turns of the pedals will keep the clutch from wearing as fast.
Im gonna look for a mini bike wheel, I've been contimplating on which wheel to use.
Do you have a close up of the throttle linkage on the engine. I mounted the cable tab to the plastic filter cover but have to relocate because it pulls the plastic. I need to make it a more solid mount.
