Had to get my speed fix today so I finally installed my K&N airfilter, fired up the beast and after warming it up to temp I pushed that throttle as far as it would go and didn't stop till I hit 160 mph.
at 2600 rpm
at 2000 ft above the ground.
If anyone is interested, with the K&N installed instead of the stock filter, I gained about 100 rpm climbing with WOT at 95 mph. Also gained about 100 fpm. I'll have to wait for a better day to do more testing.
