Really a great bang for buck! it even has 49.9cc on the side so you can confuse and amaze your homies.. I suggest one of the metal hobbit spacers for the base.. I went with .8mm spacer, and 2 paper gaskets.. everything lines up nice.. running stock head, she rips! UPDATE: SHE REALLY F'n RIPS!! If you bolt on with stock or jammy pipe and stock carb, yea is great bang for buck, itll rip... But if you empty that duct tape wallet and splurge on the VM20 carb party, along with a proma pipe, and dremel the crap outta your stock reed block/intake block thing that attaches to the MLM intake, you will be ripping PAST THE RIPPERS! YOU WILL DOUBLE THE RIPPAGE FOR ONLY 4X THE PRICE! Just friggin do it. Dont be a scaredy cat. Who cares about water bills?... Wheelie life sucka.

This doesn’t plug and play. Fins have to be cut. Piston hits head. Will update if I get it to work.

This kit definitely got me ripping nearly 45 mph with the honda hobbit "jammy" performance exhaust pipe. Required a bit of air/ fuel mix adjustment from the stock cylinder using the 16mm-ish honda hobbit pa50 clone carb. Used two head gaskets to give a little extra thickness as was suggested in other comments.
Con: went so fast my speedometer died after an hour of riding. Did not come with M6 studs for exhaust mounting, and seemed to need longer studs than what was on the stock cylinder.

Needs thicker base gasket

Piston hit the head with the linked to gasket set. Adding two more head gaskets was enough to fix that problem, but of course it leaked, so just go with a thicker base gasket.

Installed with stock carb with a 85 jet and stock exhaust. I did put an extra gasket at the case as the piston was very tight @ the head gasket. Trimmed 3 fins with a dremmel to drain the trans oil. Picked up 3 mph and better uphill speed.
