High all. Just bought the Mrs. a 250r.

The two lower engine mounts are broken so the engine is already out after just one hours riding with massive vibration.:(

I was given a PJ38 Carb that appears to be in good condition.

Please can you guys advise me on the correct jetting for the carb and fuel mixture.

The 250r has the following

K&N (in Air Box)
Lee Noble MX ported cylinder
After Market Pipe (not sure on the brand see photo)
Not sure about bore but think it around standard

As I am fairly new to quading I still have a lot to learn so to save any expensive problems with the engine I am hoping that you can be patient with me and help out.

thanks in advance for any help
