Derbi hunter/manhattan cylinder

hey guys I just paid a fortune for this 70cc kit for my derbi hunter and i broke off the skirt part of the cylinder during installation. I wasn't even using force on it I just tried to slide it down and it cracked off. I've read on here that some people cut the skirts off but the engine's intake is in the bottom end so there's a port in the skirt to let fuel and air in. Would I still be able to do that or is my cylinder toast?

If you do that^ , be sure there are no sharp edges left .

Re: Derbi hunter/manhattan cylinder

do you have any experience running motors with the skirts cut off? does it affect the reliability? and what if I just left the remaining part of the skirt on and smoothed out the cracked part? would that be okay?

Re: Derbi hunter/manhattan cylinder

Cut as little as possible off, but it should be fine.

Re: Derbi hunter/manhattan cylinder

do you have any experience running motors with cut skirts? does it affect the reliability? I'm just scared that the top end will blow up and throws shards into the case. cuz I'll never find the parts to do a bottom end on this engine.

Yes lots of experience. Maybe done this four times. All metrakits 65/74cc You’re fine. You have 8mm of skirt to work with. Give it some shape using the crack as a guide or lop it off.

There are plenty of places to buy parts for these motors.

There’s really just a crank and bearings and seals. Easiest rebuild ever!
