I don't have an "S" mines an "EVO" though and Hypers are the most fun you can have on the street without burning pre-mix!! It's undergone quite a transformation this winter too. I gutted the mufflers and made them a perforated core through flow like dirt bike silencers, Got rid of mid pipe ehxaust flapper valve and control servo, put on A Leo Vince
cat eliminator, Swapped the 4.5 lb fly wheel
for a 2lb fly wheel, lightened clutch pressure plate and Carbon open cover, Scrapped the airbox in favor of velocity stacks and pod filters, And installed a Power Commander V with auto tune and a Lcd200 screen for extra gauges and motor monitoring. Still got way too much snow on the ground to see how it'll do but man does it sound mean sitting on the bikelift in the garage.
I soooooo Can't wait for summer!!!
