Hey guy's, I've been working on car's and motorcycles for a few years after starting on those 66CC china girl engines. I've mostly given up on them.
Tried a rebuild from hell on some badly made engines after my first one broke a few years ago and just never could get it running like the original, which had decent power and was a champ for years after many rebuilds, the bottom crank pin shattered and don't have a press to install a new one but still and over all good time.
I'm not going to go into the overall detail but I did all the normal stuff to this rebuild a year or so ago many times over but just does not work well even with all the mechanical knowledge on these boy's I've got into over the years.
I was thinking maybe someday when the price comes down on the bullet train engines to give it a go, they seem really solid and decently powerful. The problem is there is limited info on peoples experience with them other than a few videos and such so I am wondering if anyone has one and has ran it for a few years with good standing.
Hope you guys have some good things to say about them but really the problems are also important, it's a curiosity at this point but I have fond memory of riding mine on and off road and would like to build a real banger with good power sometime.
