Ultimate China Girl Engine

There exists the small possibility that I may be able to talk Jim at Creative Engineering into building a few "Re-Engineered" engines, his last words were "I will do it in a batch of 12 to keep costs down, but it will be between $350-$400. I would consider a core exchange program" "I also am not sure other than balancing & blueprinting what folks want"

So there you go, if you were getting an engine like this, no vibration, high winding, what else would you like to see Jim do to it? Maybe make it 80cc for real??Reed Cage???

I have already ordered Serial #01, so all we need is eleven more--- Walter F

wow where can i order and is total cost complete and assembled $300to$400?

I have been researching engine coatings for a while and would like to see how they would affect the Happy time engine. I am thinking about a ceramic coated piston with dry film lubricant sides and an oil shedding film underneath. There is a shop not far from me that offers coatings such as this as well as cryogenic treatment to all kinds of engine components. The shop has a patented process were they cryogenically treat gears and micro finish them to eliminate noise, vibration and increase power. I would like to see this process applied to HT gears. If you combine a balance and blueprint with these technologies you would have a HT that would be worth the extra bucks to me. Is it cost effective? I don't know. There are several coatings and cryo shops out there in every state. They are just the tightly kept secret many racers use for their edge. I tried to post the link to the shop close to me but forgot I don't have enough posts yet to do so. Google evans performance in Georgia or another coating shop by you to see the possibilities.

Sounds like you are copying Chris Hill from Canada.
If there is a market for them.
Go for it!

Now if you are going to do something unique .
Like
Aluminum. cooling fins
Brass. cylinder liner Or steel .
Chrome. cylinder coating.
With a Balanced crank.
And American bearing's.
WOW!!!!!

Jim doesn't copy anybody-don't know who or what a Chris Hill is but I don't think they do what Jim and I are talking about. Balancing the crankshaft for low vibration, fly-cut all mating surfaces,USA bearings, all hardware will be replaced, new intake with reed cage, and maybe making it a true 80cc engine plus more. The idea is to make these 12 special engines reliable, vibration free, with increased power and performance as a by-product. Don't know if your Chris Hill does all that but I never heard of Chris Hill Walter F.

Sounds like a motor I would be interested in. I like the idea of improving what is there already.

Walt,
Chris Home of the CH bicycle engine, CH80 Bicycle Engine Kits by Chris Hill, Motorized Bicycles, Bike Engine, Bike Motor, Bicycle Motor kit doesn't go to the extent that Jim and you are talking about but he builds one fine engine. I have a little over 650 miles on mine and I've never had to tighten or replace a bolt, it runs smooth, quiet and strong. You can read about the CH-80 engine here. Not trying to take any business away from Jim just letting you know there are others out there who see a need for improvements to the Chinese engines

Now I know what a Chris Hill is, thanks 2Door. Walter F.

Well robin we are just at the talking/getting buyers lined up/seeing what everybody wants stage.

To answer your question: Contact Jim Swarthout @ jswarthout@tampabay.rr.com or phone him during business hours, he likes to talk bikes. His # is 727-483-1693. To answer your other question: Yes the 12 engines will be assembled and run, possibly on a dyno!

The main thing Jim needs now is input as to what problems most need fixing to assure reliability. He's leaning now towards making a new crankshaft for a couple reasons, Increase stroke for more bottom end torque, the crank would be balanced right out of CNC machine, can be weighted properly for displacement for quicker acceleration, no or very low vibration.

Jim knows these 12 engines are not for everybody and he does not want to sell to just anybody, you see these will be like Jim's babies and he wants them to have a good home. He said something about interviewing prospective customers by phone before accepting their order.

I'll try this another way- WHAT IS THE ONE THING YOU HATE ABOUT THE CHINA GIRL ENGINE AND WOULD CHANGE IF YOU COULD??? Come on gang this is for everybody - What's the biggest gripe?

A bullet cylinder with hexed fins would be nice @80cc if the bottom end can handle it. I chopped off the front mount until it was flat and put a U bracket with two 1/4 inch bolts through the crank case. Notched the magneto cover. The bracket does not hit the magneto. Fine work but not with CNC. I would say it is bullet proof. Thinking of running 1/4 inch studs through the rear crank case and cutting them off with pipe dope on them but have not had time to see if there is enough metal in the case.
