[Nothern]

Hi Guys New here but i need help and good help.
I was on my way home from work when all of a sudden the front end started to vibrate as i gave it some more gas.
the vibration is most obvious when standing still and letting the motor rest at around 800-1300 rpm or when you have a gera in and the revs are att 1200-2200 revs.
To add som flavour there is a burnt smell to the whole thing. Smells kinda like burnt rubber or plastic.

Any suggestions??
