Have not heard about a YZ85 (47.5 bore) grafted to a BWS 52 stroke crank..I tried a BWS 52mm crank in Mina cases with an RM125 top end,sadly the cases failed at the track (too thin)...My next try was splicing an '82 YZ125 case crank and top end to a Mina block,went much better!It was spooky to ride due to the strong starts even in a drag frame...Here is a bit of info on it; 49ccscoot.proboards.com/thread/7119/snoopy-dragscooter-build?page=1Working on the Mark 3 now,hope to post some pics when it gets a bit further along... There's some super secret Honda tech that involves preheating the engine cases and building up layers of weld around the crankcase web area to allow larger cranks to be installed after machining, however you didn't hear that from me.

The green Aerox is a german guy who did it all by himself.. It isn't even that hard to build.. Making it run right is a different story.
There used to be a guy here over 10 years ago who actually made a "billet" engine block himself, using a 250cc dirt bike cylinder and Piaggio CVT etc (at first he used a piaggio maxi engine block, which broke pretty quickly though).. That was the craziest project back then. He actually destroyed a dyno with it ( I think the screws for front wheel mount of the dyno just broke off) in a video (couldn't run again that day obviously, but it wasn't even starting to get to rpm).

So I'm not crazy! I found it! But this guy went the twin route Okay, so I got in contact with the person who produces the plate. He couple's it with a 54mm crankshaft and it uses a rs125 cylinder. The crank and plate go together for 300 usd. I shouldn't have dug deep in this rabbit hole Can you get me one or the guys contact I nfo??? please?
