mi wilderness 250 from puerto rico...this is my bby, 250cc engine chinesse 4,stroke..soon come with a drag style ...question? these engines can be modified?A friend said, buy a racing cdi, exhaust, carburetor and piston racing but do not know if it works ..

 

I have the same atv engine that I put in a racing mower, I had to redo the wiring harness and replace the cdi cause they were both all messed up. I did find a performance cdi at redcat online product #cd270-32. My only problem is the plug that goes into the cdi was broken and now I dont know where the wires go. If you could possibly take a picture of your cdi plug showing where the wires go it would be great. Mine has five wires. My email is rcpilot4@gmail.com.
Thanks,
Cole
