KX500 shifter kart build

[Motorrad]

didnt we used to have a member that had a kx500 outlaw kart?   I remember stewart building a motor for him?

I also fabricated a new J-arm. The CR arm is almost identical to the KX, but the CR  has a finer spline count than the KX.  So I bought a Moose steel KX500 shifter and cut off the shaft mount, then fabbed everything else. KX's are notorious for hard shifting so I added about 5/16" of length to the KX arm to get more leverage on the shift shaft. The shifting feels excellent. Here's a few pics.  The std CR arm is on the right, and the KX500 extended arm is on the left

I was able to get a few more accesories fitted up. I have the lower rad hose routed, I also fabbed a new hanger strut for the air filter. I'm now working on getting the clutch cable to work. I need to machine a special bushing to adapt the shifter kart clutch cable to the KX500's mount at the base of the cyl. Once I gave the parts machined i'll add more pics.

 

Here's a pic with the nerf pod installed :

I think it was Flyin9

is he still alive or was it a fireball/pearly gates interface type thing?

I certainly don't need extra hp, if anything i'm focused on delivering smooth power. I wish I had the clearance to run the FWW,  but a FWW will rub against the seat. I might be able to get a smaller seat to gain some clearance. First we will see how the power is .

See how the power is??? You're kidding, right?

More progress on component bolt ups. Got the engine mount alll finalized and in place. It fits perfect !  I have to fit one more brace at the rear of the mount. There is a "jack" bolt that runs from the axle block and fits against the back of the engine mount. The jack bolt keeps the engine mount from possibly sliding rearward from chain drive torque.

Here's a pic of the carb, and air filter bolted on. Everything is fitting pretty smooth, it's just that space is now very tight !



Here's a pic of the fuel pump pulse line installed:

How friggin' radical would that be pulling out on to the local kart track with a mega-tweaked KX500 shifter that pulls 10K down the front straight ? That engine sound would be NASTY !!! I surely think the 125 guys would be drooling. (and I would end up putting the kart in the safety barrier at the end of the front straight... i'm not the best driver.... yet  LOL
I do have a local outdoor road course F1 outdoors  http://www.f1outdoors.com/ ,  i'm not sure if they would let me take my kart out on the track for a "fun" beat down...

That track looks sweet. I want to try it out now too. If 10K could be done I think everyone would be drooling. It would make 1400cc crotch rockets sound like mosquitoes lol.

Well coming down the home stretch ! I have all the coolant lines routed, and Got both the throttle cable , and clutch cable all done as well. Seem everything functions as it should. Got the engine electronics all routed (hell I even have spark !  )
Here's a few pics of the final assembly. The pipe in the pic is not the correct pipe. The pipe is actually the CR125 pipe, but just gives you a rough idea. The KX500 pipe i'm sure will be much larger. I'm just waiting on the pipe fabricator, They are booked solid with drag race pipe builds for the next month..
