New Vibration "Bad"
Good day Gentlemen.
On yesterdays ride, I noticed a slight vibration as i come off the power and as the motor comes down from the higher RPM. By the end of the ride it was very noticeable. It feels like it is coming from right under the seat??
I just a had new tires put on and I will mention this. We hit a pretty bad bump, didn't see it till we felt it, two up. There did not seam to be any visible damage after a quick inspection.
I have not had any time since last evening to even look at it but, with every's vast knowledge, I was hoping someone might give me an idea where I might start looking for the problem.
Thank you!
Wayne

Definitely take a good look at your swing arm. Especially where the axle bolt runs through it. Known weakness on these models. One side of mine cracked under the axle bolt and was allowing it to flex. My rear tire rubbed everytime I hit a pothole or bump in the road.

If you dont seen anything that was suggested here take it for a ride and when you feel the vibration pull in the clutch and see if it goes away.

I did just that. I pulled in the clutch and the vibration went away. Braked smoothly with front and rear brake. If I let the motor bring down the speed, as the rom gets lower, the vibration gets worse. I did however note that with my bride on the back, the vibration is worse.
I did a quick inspection of the rear swing arm and it seamed tight, side to side and up and down.
Looking at the front motor mount, not sure if it is bad, can't tell what to actually look for.
All nuts and bolts o checked were tight.
Where exactly is the engine to transmission bolts located?
Thanks everyone for your help!!

Seems a bit odd, but I'dd also check the belt tension based on this comment.. Also, the suggestion regarding the swingarm was more about it being broken/cracked by the axle, not necessarily loose.. Double check that if you haven't already.

Riding this last Sunday and the belt broke.
I just picked up from the shop and it was determined that the two bolts holding the front motor mount in were missing. The motor was a bit crooked and put to much pressure on the belt
When I had indicated I checked the bolts and all seamed to be tight, well, those bolts were already gone. Not ever having to check those before, I didn't even know there were supposed to be there.
The shift lever was worn pretty bad, so they replaced that while the primary was off.
Gained a tremendous amount of knowledge.
Thanks to everyone who responded to my thread!
Now, it's time to go for a ride!!
