Mine has more issues than the image , so not really interested in restoration.
Bought one recently.Motor is in good shape but has a funky rewind kick starter.50ccs and needs lots of work on the bike itself.
Planning on buying a 90cc and replacing all electrical and the front end due to damage.
Couple of options on the front end , I can go with a MTN Bike forkset and use the original Honda rim after having it relaced and using a new rear hub for the Express and having it relaced as well to fit the new engine .
I have a question that I need answered 1st though.

1) What is the diameter of the GY6 rear assembly with drum brakes?

Any opinions on this and please give me your thoughts on this swap.

Do you mean on the engine? I would say about 6" maybe a little less
5-7/8

The rear wheel hub on the GY6 13" wheel is 6" O.D.

Hey, whazzup? I was working on one of my engines this morning and thought I'd take a couple pics of the rear end since you were asking about it. Hey! Not THAT rear end! Anyway, I can take more measurements if you need them, just let me know. By outer rim I mean on the outside of the metal case, the red dots are on the inside of the case rim.

It's a long case if that matters. Rich

Thanks. That is for the 150cc? I am going to try and post some pics of the Honda I have.

That 150cc is too big to utilize the spoked rim from the Express.
