You can try, might be alright since it is small. They never shafted me an did my orders good ( paypal is a must), but I hear horror stories...

I looked at those but hot damn $54. That's half way to a harbor freight welder to make your own out of old scrap laying around. I started designing a new beefier one to print on tinker cad but now that I think of it I'll just modify the one that is already done lol. It hasn't broke yet or anything but there is no reason for 1mm walls lol. I'm thinking 3mm walls should hold.

Got any 1/2" aluminum plate? You could make that adapter quite easily.

Heres a picture of the cylinder off of one of the 100cc steel sleeve engines. You notice the dark gray round part of cylinder, that's the steel sleeve part of cylinder.

Those transfers need some love.

I'd just drill some holes in flat steel and buy a cheap tap to tap them. I have a shop, so thats what I do, and I use the cheap taps. lol.

That's a spare 49mm cylinder there @Chainlube it's never been touched, got to have extras of everything!

I already have a few taps laying around and a tap and die set somewhere I can't find for like 3 years now, since I moved now that I think of it. I'll be buying a new set in a couple weeks. Work season is coming to an end! Yay!

My little Auto-Mini had a 48cc 2t, that was a fun bike. The guy I sold it to, sold it to someone else and it's still running strong.
