2004 ZR120, excellent condition, with upgrades. I bypassed the governor the CORRECT way by separating the engine casing and plucking the plastic governor out, which would otherwise come undone at the higher RPMs. I put a lower geared chain and sprocket upgrade on to dovetail nicely with the higher RPM range, along with the static, mechanical chain tensioner to replace the crap spring loaded one from the manufacturer. Air box delete kit with the adjustable carb mod rounds out tye performance upgrades. I also installed the replacement patch for the flawed gas petcock design from Arric Cat. Needs nothing, runs great. Takes about 5 minutes to warn up but flies after that. 17 mph max from dealer, this goes almost 30. Price is firm.
