Bike back end vibration over 115kph
Took the bike out for a ride yesterday and noticed at speeds over 115kph that there's a distinct vibration from the rear of the bike. At 120 - 130kph it's almost getting to to the point where it feels maxed out - although there's more power in the bike the vibration makes it feel pretty uncomfortable.
I bought my 1100 V Star Custom in the spring, but due to a lack of license here in Quebec I was unable to ride it until I passed my test last week. Over the months I was unable to ride it I switched out the stock exhaust to Cobra Speedster Longs, and switched out the baffles to their quite Quiet Core baffles. I never rode the bike with the stock exhaust so have nothing to compare to.
Any ideas? I'm thinking the vibration may have something to do with the exhaust or baffles, but I really don't know. Anyone else experience vibration like this?
Many thanks as always,
