New engine for my 1978 125 wr

bought my husky this summer, and now it looks like I didnt do a very good buy. I find a lot of faults with the engine, cracks, screwholes without thread etc. I think it could be less work and less money to buy a new engine.

Does anyone know whitch engines that can bolt on this frame? How new engine can I put on this?

Thanks alot

Joniver,
There is usually 125 parts on ebay. Cases, tranny's, etc....
But a lot of that stuff has issues as well.
Striped threads, you can drill out and redo with thread inserts.
Cracks can be taken care of by a good magnesium welder.
If it is cracked around old chain cover lugs. You can thread bolt in what is left and he can weld it back up.
I struggled for long time trying to find cases better than what I had to work with.
Someone on here might have a good set of cases as well.
Keep going and you will get it done. If I run into any, I will let you know as well.

Husky never made special frames for the 125 so any engine within an engine type of any size that came in that frame ('74-'81 250, '75-'77 360, '77-'80 390) will fit with the right motor mounts and pipe. If you want a 125 engine, they are all the same '77-'83 except '82-'83 had a different top end, but the cases are the same so those will fit right into your frame too.
