The one thing that I do not understand about some of the China made engines is why put all that effort into designing and building these engine and put cheap parts that will not hold up, Such as bearings seals and so on, It would probably only cost a few more dollars to do it with good products and then they would be turning out a good product.
When I was talking to Cathrine about there engines I had no idea that had bushing instead of roller bearings, Plus there price on the engine even as a importer is not that cheap.
I am getting a custom design 100cc that I have said what I would like it to be and been working on it for about three months, The motor is now in it third week of testing and if all goes well I will have it in about two to three weeks, Plus my cost is not what RCGF wants for there engine as a importer.
The one big hurdle was the carburetor, Could not get a good one in China so had to buy here in the sates and ship over there for testing..
If this 100cc puts out anything like the 51cc it will be a stump puller. Really going to be a 102cc
