Check your Throttle cables and the Rechecking of TPS is simple with your year of Bike. When out Riding the Bike if the Bike Responds properly and doesn't rev up at any other time then Reset the TPS(Key Turn Method) for 08+Buells after the Engine has warmed up for a bit. It isn't often but I have seen a Clutch that causes that RPM Scale Slippage to go up/ but a Very Small Adjustment in the Clutch May need checked . The Easy and Small Things First. Hope this helps.*Jimi
