Post Aerox 50 swap
Hello guys! Im new here but decided to join to get some answers. I have a ruckus and recently picked up an aerox 50 motor with a stage6 70cc lc kit, malaguti pipe and dellorto 24mm vhst carb for $200. Hell of a damn deal! I was given a universal electric fuel pump with it because the guy says it was starving for fuel up top. Now, i know the 24mm is way too big for this setup so could that be why its starving for fuel? He had a mikuni pump on it but it wasnt given to me. My other question is - if i were to put a stage6 hpc crank can i get away with using 93 octane fuel? Only 2t i ever messed with was a chinese pocket bike 2t with a big bore that i adjusted squish and all that. How do i find what year engine it is? All i know is its a long case minarelli.

Damn, you practically stole that motor! Good deal.

So what Stage6 70 kit is on it? Streetrace, Sport Pro, Racing MkI, MkII, R/T? Depends really on the cylinder. I'd think the sport pro and racing will work just fine with the 24. A bit much for the streetrace and not nearly enough for the r/t.

Is the fuel pump electric or vacuum operated? If it's vacuum, did they tap the case or is it from the intake? Not that I know much about the vacuum operated pumps, but I remember seeing on Ruckus threads people tapping the case for vacuum for the pumps and thinking it was odd when you normally get vacuum from the intake? I assumed (because I never asked why) that you get a vacuum pulse?? Hell if I know.
Anyway, have you tried just gravity feeding the carb to see if it'll run? Just a thought...

I just took the cylinder apart to see whats going on. Doesnt seem like the guy knew what he was doing. He was running 65:1 premix...thats nuts. Anyway, he tells me its a Racing Modular kit. I cant find squat about it. Im wondering if i can keep the cylinder and just get a piston that accepts a 12mm pin and get the hpc crank. Its got a stage6 billet manifold and its got a nipple tapped into it. Just not sure if an electric pump will flood the carb. He had showed me a video of it running and it def looks like it ran but im not sure he had too much knowledge on how to tune a 2stroke.

This cylinder?
http://scootertuning.ca/en/liquid-conve ... -12mm.html

If it's this cylinder then all the other parts you have won't work with it. It's a straight up race cylinder and needs race parts.

EDIT: If this kit is in it then you already have a 12mm crank.

Nope thats not it. I took some pictures of it but ill upload them later. Looks to me like an mk1 kit. Still looks pretty new but i see some markings on the piston that dont look too good. Im just gonna redo the whole thing. Already a stage6 HPC crank. Next is a mk2 sport pro cylinder kit. Good thing this engine already comes water cooled. Not sure what pipe to get though.
