If you bolt on something different, hopefully whatever you get has exhaust that is compatible w/ your rider. Plus, do you feel you have the patience and knowledge to adapt the replacement engines wiring harness to controls to your rider? If you had a similar rider for a donor- that would be a plus.

I think you have literally "Shot yerself in the foot"!
Us guys, and a few gals, have learned how to make other engines work, when replacing a broken engine, but, we never shoot the old horse!
Simply put---possibly with experienced help, you could have made that engine could have been fixed!

No advice under the circumstances stances.
