I have a 2007 sv650s and although top speed for the bike it supposed to be around 145 I cannot reach even 100 mph on it when I got the bike it was wired for race but I have since replaced the wiring harness, the air box, and got a new keyed ignition. The bike accelerated amazingly to 80 mph but after 4-5 gear it starts losing its umph and 85 it about all it has got. I've tried playing around with the throttle bodys set screws recently and the butterfly's do not open at the exact same time. A buddy of mine thinks I may be running on one cylinder? Opinions? Also I want to wheelie and it's just not possible with whatever issue I'm having here I can't even clutch up in first gear higher than a foot.
