Muzzys has improved the 1361 kit for the ZX-12 owner who just can't get enough! This kit is now a 1375 and includes everything you need to turn your ZX-12R into a 210 horsepower monster. Like wheelies? Over 120 lbs. ft. of torque at 7500 rpm ought to provide all you need. Want low end power for those "tough" situations? How about 100 hp at 5000 rpm? It's a straight shot from there to 210 hp at 10,000 until you hit the rev limiter! This is street-able, controllable horsepower that creates a well mannered monster out of your ZX-12R. This kit contains everything you need. It is a true bolt in; no machine work is required. The forged pistons provide a 13.5:1 compression ratio. The kit contains a crankshaft with a stroke increase of 4.6 mm, special base spacer and gasket, 2.4mm oversize pistons, rings, clips, head gasket and a bored and re-plated cylinder.
There is a core charge applicable to your crankshaft and cylinder.
A Power Commander 3 (available separately) is required and an appropriate map is supplied with the kit.
