hi there. I need some help.i have two problems with my bike. My 2009 street triple 675 wich i bought 3 days ago has a sticky rev counter. the needle sticks at 14000 all the time even the ignition is off. sometimes the needle unsticks and the rev counter works as usual. the other problem witch i have is that the bike under acceleration hesitates or has hick ups and lucks power after 7000 rbm. at low rpms bike is quick and smooth. I bought the bike from a moto dealer and no one used it for 2 years. the only thing i did is an oil and filter change and new battery. the bike has sport filter and two zard slip ons. every help and opinion will be very helpful. thank you.
