Nice bike looks like its coming along great! I have made a few adjustments on my bike but my bike runs strong with original 5hp Tecumseh motor. I have original plastics and had governor adjusted. I'm 5'5 140lbs and can do about 30+mph
I painted the engine. Used engine enamel for the primer and paint. Forgot to get a picture of the painted engine, but here it is during the priming.
I went with white for the engine paint. I think it looks decent; just can't let anyone look at it too close or they will see the paint runs! :doah: I need more patience.

Almost ready to fire it up! I am pleased with how the rear sprocket turned out. Although its so large the that sprocket will hit curbs if I drop it at too sharp of an angle (from riding it briefly before I started to tear it down).
The black cover over the clutch is an old kitchen pot I am in the process of turning into a clutch cover. Thinking white with a pink ring around it.
Now to craft a throttle linkage . . .

Well, I haven't done much with my project for a while, but I did take it around the block a few times today. (Still does not have a throttle hooked up yet, but I made it work.)

The good news is that it was the funnest 15 minutes I've had in a long time. The bad news is that it grenade'd. I haven't torn into it yet, but the hole punched into the case is a pretty good indicator. :doah:
Now I've got to read up on the forum on the Harbor Freight engines to see if I can make one work for this application. :censure:

I decided to mount it on the angled mounting plate without making a bracket for it. It seems to run fine with no carburetion issues. It has so much more torque than the old Tech did. The good news is that for my purposes (a bike for my wife) it has plenty of power without having to do any upgrades. I will have to make a custom muffler, though.
Sure, it might take a few days as I only have time to play with the bike on weekends. I can say this, though. The Predator 6.5 is actually a lot of engine for the bike. The vibration is crazy- tingly hands and feet after 5 minutes. Also, the physical size is big; the starter/blower housing sticks pretty far out on the right side of the bike (one picture shows this pretty well). And as you can see, an aftermarket/custom exhaust is absolutely necessary. The plus side is there is plenty of power stock out of the box for my purposes and it has two throttle hook-ups which made for easy work.
Finally, the bike is so light, and the wheel-base is so narrow, that even the stock engine can pull wheelies, even at moving speeds. Now I see why this one has a wheelie-bar added: http://www.oldminibikes.com/forum/project-logs/33510-my-bird-nighthawk-build-6.html
