Pulling to the right and a new vibration
I have an '03 LT that I've had for 2 years in November (purchased new) and has 36,400 miles on the odometer. The bike has developed a serious pulling to the right problem. I have to constantly keep pressure on the left grip to keep the bike tracking straight. The best way to really see the magnitude of the problem is to set the cruise at just about any highway speed and take your hands off the grips. In less than 3 seconds you have to grab the grips to maintain positive control. It will pull itself up and over the crown of the road. I am running fairly new Metzler 880s. I can't say that I can connect the problem to the installation of the new tires, but of course it is a possibility. It is not a difference in load in the side bags. I've played with that too. My dealer says that they don't notice this problem when they take it out for a test ride.
The other problem is a new high frequency vibration or buzzing that runs through the entire bike at just about any rpm. It is very noticeable in the foot pegs and grips. The bike was running beautifully and as smooth as butter until I took it into the dealership for the 36,000 mile inspection. My bike would run at 5000 rpm and you could feel almost nothing from the engine. Now it puts a tingle in my feet within a few miles and nearly to sleep if I continue to ride. In neutral the engine runs with a constant popping sound from 3000 rpm up. The dealer doesn't feel the buzz when they take it out for a test ride.
After 36,000 miles of wonderful 600 to 800 miles in a day trips, I know what an LT rides like, and this ain't it. Suggestions on what might be happening with either problem.
Thanks for the help!
