Could you drill where it broke, and replace stud with nut and bolt ?

Quite possibly.

Just thought I'd throw out a couple links to the absolute cheapest engines I could find. EBAY!

US SELLERS ONLY!

This is without all the goodies??? Chain / carburetor / sprocket/ bolt & nuts ???

Why would someone buy a motor without that .... ?

Because they regard those kit parts as junk which just adds to the price and to the cost of shipping, and would be replaced with decent (sick?) parts anyway.
Or they had an engine that broke, maybe it's big end bearing disintegrated.. No need to replace the whole kit.

UPDATE!!

This is now the cheapest 66cc motor I could find on eBay. The other one is SOLD OUT! Man these things are goin like hotcakes

Somebody please buy one and let us know how bad it is. Hell it might be the best engine you ever owned
Curiosity is going to get the better of me and I'm gonna buy one just for s**ts and giggles. I don't know though for about $35.00 more you can get a Skyhawk GT5a replacement engine. https://www.motorizedbicycle.com/bicycle-engine-kits/grubee-skyhawk-gt5a-66cc-replacement-motor.html

Yeah I was thinking that. You could end up needing to buy a new cylinder straight away, so a gasket kit too, and then pretty quickly if cost the same as the Grubee GT5a.. That would be great for spares that fit. Or you could also buy "Nukeproof" platform pedals for that price.

 

[Hello Moto!]

The funny thing about this is my first build had a cheap 66cc eBay kit on it. I could hit 35mph on that thing pretty easily. This new Skyhawk GT5A has a hell of a time makin it to 25mph LOL! I have the exact same set up engine wise on my new bike as I did my first build. All I ran was a jetted SHA clone carburetor and same for this new bike. The only difference being the motor. This new build is probably 5-10 lbs heavier but that's it. So unless my speedometer is off by about 10mph, I'd have to say the Skyhawk is being outperformed by heavy duty eBay metal!

I hope someone can explain this and how to "fix" it.. Is it lacking power or just will not rev higher even under no load?

 

[Frankfort MB's]

It could just have all power at the bottom of the powerband

 

[Hello Moto!]

Low end power is almost non existent but it revs just fine and performs great on a straight away. It just won't get past 25mph. It's bad when you have to avoid stop signs. That's not easy lol.

Throttle is good all the way through to wide open. Biggest problem is just gettin it goin from a stop. I can live with 25mph top speed but it just kinda floors me that the cheapo was all around better with the same set up. Perhaps I would benefit from a bigger rear sprocket. I'm afraid then my top speed might fall to about 20mph lol.
