The throttle is a modified ARC type. Note the two return springs - safety first!
Speaking of safety, even though the governor has been removed, it was done to improve throttle response, not to over-rev the engine.
The ARC light-weight flywheel increases rpm and horsepower...at least that's the claim.
So here's the big question. With the governor removed, light-weight flywheel, advanced timing, improved air intake, etc., I should be getting more like 10 hp. Given that the Comet 30 is rated for up to 8 hp I could have a problem. We'll find out son enough.
One of the major problems I saw in the original Scat Cat SC214B is that the triple tree can crash into the tank. The tanks had huge creases from this happening over the years. What you can see in these next two shot are bumpers created to provide an offset. This increases the turning circle slightly, but it prevents the triple tree from hitting the tank.
You can see that the bumper hits the frame before the triple tree hits the tank.

I chose some plastic fenders because they fit very well, but unfortunately it took a great deal of time to get them smooth. Now if I can just get a warm day in Michigan to paint them!
Chipper provided an exact replacement pipe, but I chose not to use it as it would have to be modified for the Predator engine. I kept the original pipe in the event that I decide to retrofit with a vintage engine. But I did find a pipe that went with a Scat Cat equipped with a Hodaka engine and I was OK modifying that one. Seems to be working.
The tripe tree standoffs work - no more creases in the tank!
Still to do:
Fender painting
Wheel alignment and installation
Front fender bracket
handlebars and grips, brakes, etc.
Almost done!

Looks great! Loving the color combination. The scat cat I built is a lot of the same as yours, I dropped a predator in it too. I had to add a chain tensioner because it kept throwing the chain when done, I used the tav plate though. Hopefully you will be fine since you didn't use the plate. Very cool build!

Starting point
Almost done. We finally got a break in the weather and I can get out of the basement!
The pipe came out good - not exactly like it would be on a Tecumseh, but changes were required for the Predator.
The seat worked out well too. I found a really great source if anyone needs a seat.
The paint took forever because I haven't had the weather. So after 11 or so attempts it came out close enough! I just need some brake return springs, a handlebar mounted kill switch and some gas! I'll post the video as soon as I have it running.
