what do i need to hit 100 whp?

Baldy, is that your bike? If so thats not fair lol. Its so nice. And to mark, thanks for the knowledge. Id like to re spring the front forks, to keep them looking somewhat, "old" per say. Also to get 530 sprockets for my bike, im guessing i cant just go to my local bike shop and say, hey i need 530 sprockets for my 83' Kz. Should i go on Z1 enterprize or are there specific part #s i need?

Now for the exhaust, im guessing a 4-2-1 is like the factory duel exhaust? Ive been looking at 4-1 exhausts and they are damn expensive. I found a company that has pre made 4-1 collectors (i could probably make my own but it would take a while and be made by hand) 40 bucks is faster. I am a welder, fabricator, and machinist. I know there is a a lot of math involved in making your own pipes, but if i got general measurements off a 4-1, do you think it would be benaficial to make my own exhaust? Id love to learn how to do it.

Cheers
Jason

Well actually you can, and at 211 mph there aren't too many zx14's going to run away from you (but it ain't cheap). :laugh:

gonna get me one of them fancy lerned cfm calculators.... find out how many horsepowers i get from my tire airspace multiplicated by bore size divided by performance sticker to the third powers hahahaha

Yep, all mine it has been a long term project started about 15 years ago, it is scary fast. 0 to pooh your pants in about 2.5 seconds.
I also did the 530 swap on it. Used the rear sprocket off a KZ650 bolts right on and then used a JT conversion sprocket for the front. You can buy the sprockets at Z1 enterprize.

Would the front sprocket from a 650 work also? Some parts on my bike say 650 and 750. I really like that bike baldy. Did you paint the engine? If so what did you use?

No, hes talking about torque. Please read his post #561649.

But, like it was said earlier, what does the rules allow. Them little 750's can make some good power and I don't think 100 HP is beyond reach but maybe just not practical or fiscal.

No the front sprocket from a KZ650 will not work different spline count. I had Joe at PitStop performance paint it while he had it for machine work. Didn't cost much more so I just let him do it.
I have used PJ1 satin black case paint in the past with really good results.

Ok,changed horses/names in mid stream! :laugh:

Ah Les, i figured you would be in here sooner or later. Glad you came to add to my build planning of sorts.

Ok so in all seriousness, no turbos, no NOS. How can i build good street/track power?
So far i have:
1: 4-1 exhaust. Should i take a go at building my own?
2: pod filters
3: mild port and polish
4: cams. Idk what kind.
5: GPz head. Is it even worth it?
6: Ignition. Dayns S?

Thats all i can think of without going crazy in depth and expensive build.
