I'm sure someone here can help you find a good mechanic/service tech.

The cross-plane shakes a little in the lower rpm but smooths out at 3500 - 4000 rpm. This engine is smother than most inline's. If the motor is shaking badly there is something wrong and you need to get it looked at.

I bought the bike used like this with all the work done like the new plugs and that. I'm trying to figure it out without taking it to the dealer yet as I'm not In the financials situation to be able to pay the dealer thousands I'm trouble shooting labour
I will get it figured out threw trouble shooting other people's experiences with this issue .
