I have a great little 2 stroke here that has been running great for months now. I have had minor problems but nothing that I couldn't easily fix.... until now. I would like to keep using the engine considering the little guy runs like a thief but I just can figure this situation out so I bow down in humble genius of MotoredBikes.comm. As you can kind of see in this poorly lite picture taken with my phone the screw that attaches the engine to the bike has broken in two. It snapped right at the engine block. I have no clue how to get the broken piece out or the engine block or how I might circumvent this situation and still use the engine. Any thoughts or fixes out there that I don't know about? You have always been so good to me in the past with so much help, Thank you in advance for any help!

When are people going to learn..first the correct mounting is critical, the trash hardware the Chinese needs to be replace..with that said, since it broke off flush, you have a couple of options, search will find 100's like your problem. So the saying..it's like ,,, Have you searched for your solutions?
 
Been there Done that

I brang mine to a lawn mower place they were able to back it out with a tool.
Yey hardware is ****. I got some new stuff at Fastenal. I dont use the factory stud bolts, just goot bolts with some washers.
 
You will have to take the engine off of the bike......go to a parts house and buy a set of left=hand drill bits, also a screw extractor of the proper size...some extractors come with a drill bit the correct size...don't damage the threads when you drilling out the stud...
 
I found left hand bits very useles from my experiences haha. I used a dremel cutting disc (like a 2cm long by1mm angle grinding disc) cut a slot in shaft of screw (may have to graze engine block tho :-/ so careful. Then use a screwdriver to unscrew it from the groce u cut, after google "the jake bike" and look at his custom mounts :)
 
HOW can a left handed drill bit be useless?.....It just drills a hole when the bit turns to the left.....

And sometimes it'll even screw the stud out before you get the hole drilled all the way. BUT, It don't HAVE to be a left hand bit. Any bit of the proper size will work. I've done A LOT of these. All ya gotta do is center punch the stud so the drill bit goes down the CENTER of the stud. Ya DON'T want to mess up the threads. Then drill a hole in the stud, get the matching size easy out, (bolt extractor,) and spin it out. Then make sure you use better quality studs and replace them both. Also, Make sure the drill bit isn't too big, All ya need is a hole in the stud without hitting the threads in the case. Easy stuff. I don't see why there's even a debate on this subject. (Left or right drill bit? LOL.) IT DON'T MATTER. Drill the hole and extract it. DONE!!!

P.S. It's A LOT easier to do with the engine OFF the bike.
And Al is right, There's a LOT of posts on broken studs. Ask the question AFTER you've done a search. Just proper etiquette.

i tend to find when drilling out screw shafts less than .8mm the left bit tends to slip and it bite the thread, but mabey its just my bad luck

Did ya read the part where I said, All ya gotta do is CENTER PUNCH the stud. That will keep the bit from drifting.
