Built and raced by Retro Rocketeer he ported the head, milled the cylinder and head some. He ran the Versys intake cams and Ninja exhaust cams in different degrees and combinations. It had great midrange acceleration. He says, “Ultimately, its still easier to build an SV motor than an EX650r motor. There’s just a lot more R&D in the SV”. I fully agree, but I feel this could change if more US guys started to run the little ninja 650. It takes a bit more work, but has proven itself in circle track, I am sure it can prove itself road racing. He chose the Ninja because He liked the chassis setup. The balance and distribution suited his riding style and preferences. He also got a smokin’ deal on it, which never hurts. The Versys/Ninja motor’s biggest weakness are the connecting rods. You need new rods at the end of every season if you don’t want to buy after-market t race rods. The other huge weakness is the radiator. Radiators on the EX are barely large enough for trackdays with a stock engine, let alone the added output of more compression and more flow.
The front wheel and discs are 08 EX650R. Forks and brakes are 06 ZX6R mounted in 04 ZX6R triples. In current form, it weighs 372lbs with 1.5gal in the tank. Unfortunately, I suffered a severe crash at the end of my last season and opted to sell the bike. I wanted to install a Versys swingarm eventually, but was always a day late on bidding.
