If it is possible could you tell me all the mods for a z that will make it go as fast as possible-pipes jetting,filters etc. thanks

 

trinity racing has a 465 big bore kit. almost every company has a big bore 440kit. i wood get a bigbore,porting,oversized crank,oversized valves, aftermarket cam, bigger carb, aluminium airbox, k&n air filter, an exhaust system. ttry these companies below.
1. trinity racing.com 2.ct racing.com 3. powroll racing.com 4.alba action.com 5.pro design racing.com 6. um racing.com 7. moto-joe.com . there are a billion exhaust places. but i would stick with the company's pipe to make it match the performance. try 1,2, and 3 1st.

 

How fast do you want to go?

 

I want to go about 80-90 mph

 

You need to gusset the frame before you do anything.

 

Cams , exhaust , filter , jet kit , big bore , CDI and a big hill

 

I think you should get a real quad before make suggestions for a Z

 

also Craycraft racing has a kit out..

 

id say get exhaust, intake and ehxaust cams, sprockets, K&N air filter, and 440 kit if u want to spend the money

 

These guys appear to have done some serious testing:
GT Thunder

Experience with DRZ and LTZ down under indicates that cam changes whilst staying with 400cc kills midrange torque. Upgrades: Pipe, Airfilter/Carb (39 FCR), 436 kit, then cams /CDI.
