I managed to snap the entire case in half found another from a brokers £60 delivered, only down side is you will need to rebuild the entire engine as kymcos amazing design means the 2 pins that hold the case on run to the top of the engine where the valves are! I didn't need and specialist tools just a new gasket set and a lot of spare time :) the chain runs from the top to the bottom of engine just make sure you get it back on the teeth properly :)

Personally i would bin the engine just cos i couldnt be arsed with the hassle and keep trying breakers for another complete engine. Doubt i would spend out for the case cos i know i would give up half way thro building it prob once i got stuck. Surely there must be a breakers with a complete engine going reasonably cheap? For a couple of hundred quid you could prob pick up another complete scoot

Last resort is try drill and tap 4-6 holes and screw a plate on with that liquid metal stuff below the plate? It may work, may not?

thanks blue... just checked with some brakers and most 139qmb are short case at 400mm across kick start cover ours are 435mm. so i would have thought these are for the 10" wheel not 12"
will have to just wate for an engine to come along on ebay....

Do the math... Maybe its better to sale for parts and put that money in to a new scoot.Or just get a used scoot same model and use the other for parts.

+1 Good idea from streido...

I think it would really work when done properly, I would even try a liquid sealant like Curil instead of epoxy - it's guaranteed to be oil-proof and heat resistant enough for this application, and also cheaper and easier to work with...

Take care not to leave some large aluminium chips from drilling in the crankcase. Use a sharp drill bit and drill very slowly so the bit produces one continuous chip of aluminium instead of loose crumbs. Also try to stop at the exact moment the drill is coming through at the other side of the material... With a bit of luck (no pun intended ;D) you can get away with this without disassembling the cylinder etc. Drain and filter the oil afterwards, and repeat this after letting the engine idle for a short wile, just to make sure there's nothing left in there...

Update : It might even work when you use liquid sealant or epoxy to just glue an aluminium plate over the hole, without drilling and tapping for screws, it depends on the surface area that's available though... Also make sure that your crankcase ventilation isn't blocked, so there's no pressure buildup..

Its gotta be worth a try? The case is f***ed anyway and youre already lookin for a new engine so whats the worst that can happen  ::) ::)

I would def tap the plate on if i could, you would need to check the bolt heads wont hit or interfere with anything in the cvt tho, variator, belt etc if you do bolt it on. I cant see it coming off if its bolts in place and the plate with the sealant should be solid if done right. What you got to lose apart from time and a tenner for the sealant? If you need taps and drills i can prob get you some from work and post them down if you want, long as its only a quid or so for postage, i "borrow" them for free.

I would locktite in the screw/bolts too.

Maybe use like 4x or 6x small panhead screws at 4mm-6mm's. If you cut a small patch of thin steel and shape it into the contour of the case by lightly hammer it over where you need it before you gunk it up with the sealer it should work i reckon, at least for a while.

Just need to sort out the bolts/screws.....
