I notice the same thing from new to now, as my 2009 get more mileage it started to vibate a little bit, one problem is I need 2 new spark plug.
Hi Guys,Terry Dill said:Another thing that can cause vibration is having bad gas. If your octane is too low you are not getting an even fire for a good clean engine rev. Most of the time this can be heard as a pinging in the engine. But if it is really bad, the engine will vibrate causing the whole bike to shutter.
I would put some good gas from a reputable station with new tanks in the ground. Maybe go up one grade and see if that doesn't solve some of the problem. If it does, then maybe your timing is off. I remember my father would run his engines a little bit further advanced that what the specs called for. But, to make up for it, he had to run higher octane gas. It could be your engine computer is off a bit for perfect engine timing.
You said the problem is getting progressively worse. Could what good gas you had is getting more and more diluted with bad gas.
I note that you have 15600 miles on the clock I take it that all filters and oils have been changed recently along with the CVT filters and oilsSttarbuck said:That’s exactly the way it feels to me only I’m in drive in the automatic mode. Changing to manual mode goes to forth needing third.
I would say either is not needed, I would just work a few tanks through. Usually any contaminates are at the bottom of the tank, so they will be the 1st thing out as the tank empties.Coffee Cup said:I may use an additive to disperse the contamination or have the tank drained if needed.
