Ralph schreef:Why dont just put a V8 in it Sounds good, are there any other KFX's with that much HP?

Not many, there are only about 4. 2 of them are in the same city as me.

I think I could have beaten them both.. the bike pulls so hard.. if I could just keep the wheels down I could out torque them... I am working on a longer swingarm... that should help. Sooner or later I will rebuild the bike to run the other high psi pulley. that would give me aboutr 30 more HP.. the...

I am having SERIOUS problems keeping the front wheels down... the blower gives you max torque just off idle... it's like trying to launch with a 30shot of nos and a stock swing arm...LOL I really didn't want to get the longer swingarm, I kinda like how ridiculous it is to have a blower with a stock ...

Check this out, this is just for the races on Sunday. :) http://www.angelfire.com/al/metalalien/engine/blower_surprise.JPG Toegevoegd na 90 uur 20 minuten: look at this one... 117hp no nos or anything, just motor. this is me racing him... he had to give me a rolling start..

3" pulley 1/4 throttle only! I was limiting the bike to 10psi... my 4" pulley came in today... Not nearly as crazy as the 3" but it still feels like a big bore shooting NOS the whole time.

I can't get home in time to video during the day.. I will do some daylight video this weekend. Still tuning.

First ride tonight... it blew a 15psi! I still haven't reached full throttle! That means either I get a new pulley to lower the boost or change the engine to handle the power...LOL Here is the new video... remmeber I can't stay hard on the throttle until the jetting is right.. lean means bye bye mot...

I am friggen tired! I have been leaning over that bike all day... I will tell you one thing... it has INSTANT throttle response and it smells great. :lol: You can feel the pressure coming out of the exhuast, it really feels powerful... Much harder pump than a normal 730. 1) I need to reroute the thr...

It has a tension bolt, and then 2 more to hold everything tight. As the belt gets loose you tighten the tension bolt.

yamaha tri-z schreef:i thought you would make the 3rd pulley an adjustable one.
so if the belt would strech you can control its tension

I did make one, I just haven't put it on yet... waiting for the last pulley to get here.

Don't know how much torque, but it will be alot...

lots of pictures in this thread..

Sorry to link to another forum but I don't feel like reposting all of them.. it's been a long day...

omg, that's nice man :shock: how much horse power do you have on your kawie? greetz john As soon as I get that pullley I am going for 10psi (for now) which should give me about 130hp. Later on after I rework the inside of the engine I will go for 15psi which should put me at around 150hp. The great...

just waiting on the last pulley to get here...!

Of course that first picture is fake...

But this one is not!
