this one is small but i odnt think it has a tranny so this one is out i think. http://pensacola.craigslist.org/mcy/1766602327.html

this one is my choice, it just needs an ignition, which i can get the whole thing harness and ignition for 100$

Bit worried that the KZ doesn't have air filters on it. If it's been run like that it will be knackered.

Not sure on the specs for the nighthawk, I think it's either a 650cc or a 700cc. This is a seriously powerful engine and nearly everything on the kart will need to be REALLY strong. I wouldn't want to drive a kart with either of these engines unless it had front brakes.

im using a race kart frame, what kind of frame work would I be looking at?

 

[kazkepox]

as far as the quality of this engine do you think its worth the buy?

 

[modelengineer]

Not sure how you'd modify the frame, others here would know more about that than I would, but if I was making it from scratch I'd probably use 40x40x1.6 tube for the main frame rails and 25x25x1.6 for the bracing.

I think you will need to modify the frame a hell of a lot just to fit the engine on there. It might be worth making a frame from scratch for it, and get a Yamaha KT100 2-stroke engine for the racing frame so you can race it in competitions.

yeah thats why i said put a briggs 5 horse or GENUINE honda on there... its a easy bolt in and on your way no horrible frame modifications to fit it..

The kz400 is too big for a race kart frame, and for the record mines newer haha.

The 125 would be your best bet as far as space, and it does have a tranny.

contrary to beleif, I am going to be buying the knighthawk and build a super kart. sinc emy purpose was for drag racing anyways, i think it will do fine...and there are tons of websites that shows how to mod a racing frame for alarge bike motor. I left for a while so thatI could regain my thoughts. and this is what im going to do, and im going to stick wtih it. I also know more about motors than when I was last on here.

my other choice was to buy it and save it for a buggy project
