Pulsation at speeds of 115KM plus. Also seems slugish

[spydertrike]

2012 RT-S 1000KM OR 600 Miles.

I'm having an issue with my Roadster.

When I'm driving in fifth gear and the RPM is around 5200 to 6000 and the speed is anywhere between 115Km to 125KM I experiance a pulsation feeling through the handle bars and foot pegs. Even the engine has a strange pulsation sound. It's almost like the bike does not want to go over 115KM. It comes and goes.
The dealer thought it was an update required to the computer system which they did but I still have the problem.

Any ideas? It is going in for the 600 mile inspection next week.

I also find the bike to be slugish when starting off or when giving it throttle to speed up. Perhaps this is normal for the Roadster as I'm use to driving a two wheel with a 1600cc engine. Any thought ?


Thank you

Sorry, I got nothing. It might be an indication of possible throttle body or vacuum line issues. My RT-S loves that rev range, sometimes my wife doesn't though. As your going in for service soon I suspect that if there is an update required to the system, your dealer will do that.
