Hello,

I recently purchased a MC21 here in the US. Everything was working good but now one cylinder is not working some how. I am new to working on motorcycle also.

The engine starts and runs. If i am sitting on the bike the pipe next to my right feet does not get hot. That is the side that is not running. I see one spark plug behind the front tire and I took that out and inspect it and it felt little warm so I am guessing that one is the Ok one. The other spark plug seem to be under the tank I am not sure if the tank need to be removed to get to it?? DO I need to drain the gas first to remove the tank?? Never done it before.

Any quick easy fix?? thanks.
Also I am also wondering what model I have?? Wet or dry clutch?
I will post picuture later

thanks.
Jim
