Hi Mitchell,

Sorry for the delay in replying. I've had criminal trial all week and the usual long hours at my other career as a Deputy Sheriff/Evidence Technician.

Q:  "...i own a zzr600 e4 and i want to speed it up i have a k and n filter and jet kit it will top out at 150 mph at about 11.000 rpm how can i release more power from the engine

A:  There's numerous things to do to the engine to increase performance. Change pistons/stroke, performance con rods, Falicon crankshaft, porting, cams, degree cams, performance ignition, valves and 5 angle seats, the list goes on.

It would be easier to change final drive gearing to gain top speed. Change gearing for the various TRACKS in which you plan to release all that power. : )

I believe begins at 140, but so does jail time and restitution. Ride safely and responsibly on the street or I may process YOUR crash scene.



Q:  "...also i was looking at a set of race cans on ebay but they are not for my bike will they work because im sure race cans are straight through pipes"

A:  I cannot say if they will work or not. There's not enough information provided about the parts. I recommend buying parts designed for your MC.
