I know no one wants to hear it again, but if you can't kick a 350x but you can kick a 250r, your not following the starting sequence for the 350x. I fought it for years until one of the members here showed me how to start a 350x.
I do have a Goki for sale now for that very reason. I no longer need it because I can now start the x with no problem once I learned how. The GOKI I have is very complete and in very good condition if anyone is interested- but it won't be cheap.
