The clutch leaks on the rt side. The demo sounds like a bag o' shite. The position of the vent is a recall. My transmission is silent but the valve gear is quite loud on these motors. It should still be pulling hard at 8k rpm.
Buy elsewhere. If the dealer can't be arsed to maintain his demo bike, how much care do you think he'll take with yours
I don't know which dealer your using now but Mchr HD seem to have got to grips with spannering the 1125 and I've had nothing but 1st class treatment from them. It would make sense to buy from them, even if it meant travelling.
