it not good. but as long as nothing is leaking out, you should fine.

Re: cracked engine???

Yeah... You can buy "JB Weld" at pepboys or autozone. This stuff is originally a thick epoxy-like compound that becomes very hard when dried, almost as hard as metal.

On the package it says that a farmer used this stuff to fix a cracked engine head on a tractor and he still drives the tractor with jb weld on it today. Should work on a moped...

Good luck and wear some elastic band round your jeans until its fixed or it could be nasty!!!!!!!!!!

whoa i just looked at the picture again. looks like your missing half the case!

Re: cracked engine???

is it going to effect the way that i ride is what i want to know

Re: cracked engine???

Dan,

A crack anywhere is bad on the ped... But if it still runs smoothly and nothing leaks, you lucked out. But if it leaks, JB weld will do the job.

Re: cracked engine???

Dan,

The only way to find out is to fire it up and drive it. We can't tell you anything until you actually take it out and drive it.

If it starts and further damages the engine, then it doesn't matter anyway-- It would have happened one way or another. Thats how bad it could be. There is no risk in trying to start it and ride it. But you are better off keeping your legs high up just in case something metal shoots out of the engine.

Then when you see the results, share that with us. Tell us if it leaks, what color the leak is, etc... What happened, etc... If there's anything out of the ordinary.

But a crack as big as that is pretty bad.. I'd be surprised if it would run without any work.

Re: cracked engine???

Dan,

if your moped does start up and works fine, you will have to fabricate something to hold your crank to stop it from bending. It will work fine for now for testing purposes..

It does look like your engine may be history, though. It'd be a good parts engine if you got a new one. (Thats what I'd do. Save a lot of headache and b.s.)

Good luck man.

Re: cracked engine???

no like i rode it for 2 days and it runs great. I think it was just like (im gonna relate this to like a pedal bike) i think it was just like a chain gaurd like a regular bike would have so like you bant leg doesnt get caught in the chain.....but when it comes down to it you dont really need a chain gaurd. it basictly was just a shell that went around the engine sprocket like it doesnt effect the ride or anything, and EK why would it bend my crank......like do you guys get what im saying

it doesnt expose anything from inside the engine it just exposes my front sprocket

Re: cracked engine???

Dan,

I see what you are saying. The original case did cover that hole did it? That rod going out from the sprocket looks like its long. Wasn't there anything in there to assist it in staying in place?

If your moped runs fine, then you're all set, although, you'd want to watch your pants... It'd suck if you were going up a steep hill and your pants got stuck in there and you can't pedal...

EK

Re: cracked engine???

nothng held the rod in place and it would really suck if that happend.........but ya no ill take my chances lol

John Joedicke /

Is that a 31 sprocket on there? How much did or didn't you take out of the casing. Just order a new side cover from Ike or look on E_bay for a replacement. No big deal there.

Re: cracked engine???

i dont know how many teeth it has its just a stock sprocket i think.............i want to get a speed sprocket though if anyone has one for sale let me know

Dan

Re: cracked engine???

hey i got to tell you that happened to my tomos lx and it did not don any thing to it you just have to be careful if some thing you hit my get stuck and my lock the chain and if your going fast and something makes the chain lock you might flip be carful but it did not do anything to my performance had the bike like that for like a year

Re: cracked engine???
