Genius idea with the copper sleeve. A lot of work on that little baby. Are going to put wheelie bars on it. Lol the weight is going to be heavy in the rear... but low to ground.
yeah, fun project, might want a guard on top of the radiator..? Also no hose clamps on those rubber mounts? IDK, look forward to the finished project, your having fun, hope it all fits together.tc ATB and rubber side down!!
Hey what if you put a temperature sensor on the block And run a temperature sensor through a reley that turns on fan and water pump so when the temperature gets too hot the temperature sensor turns on the fan and the pump and That way it works as thermostat
Totally possible. I wasn't concerned about too cool as the ski runs river water as coolant. I was only worried about too hot and with a single radiator it was definitely climbing into areas too hot for me.
@@thedutchmanandthedigger1500 even whit pump constantly runing ? am planing on doing a same build I got kawasaki 650sx motor And just looking for the right ideas for water cooling what needs to be done what kind of radiator do I need and if to run a fan or not
The pump constantly running did not bother me. Keep in mind that a ski motor basically can run too cold. You better plan on 2 radiators. Are you going to use a jack shaft or straight from the 650 crank? I had to have the sprocket for the ski crank custom threaded. I may have it in my shop still.
Yes and it injects water from that jacket into the exhaust pipe. This is what makes it an open cooling system. That particular problem was addressed in a video.
@@thedutchmanandthedigger1500 I recently accuired a 701cc Yamaha wave runner, double two stroke. It has a threaded output shaft, I've been working on a link to make a Polaris CVT compatible with it. Also just needing to pick some brains about water cooling issues.
Cooling will be an issue until you understand how the system works and find where it dumps the water into the exhaust. I do have a couple custom made sprockets that may fit the output shaft. I did buy Polaris primary and secondary drives as I too was thinking of going that direction. May even have the belt and shaft. I chose chain drive to keep it all close and tight since the Polaris system had to be a definite Lenth and I did not want to stretch my frame.
@@thedutchmanandthedigger1500 I'm trying to watch all you got on the jetkart, I'm glad I stumbled on to it. I'm not having much luck with finding a lot of info on this subject. Alot more of the snowmobile /kart builds. Any wisdom that you can send my way would be greatly appreciated.
Actually it turns out to be quite undriveable. Can't keep the front end heavy enough to make it turn. Thinking of swapping the motor out to something else.
Amazing build!
Water pump was just a Harbor freight 12v

Ended up pulling the motor and doing a 11 hp briggs.
Great work !

Hadn't thought about clamping the hose on the mount. I'll have to watch and keep that in mind.

the exhaust manifold ha a water jacket , doesn't it ?
Yes and it injects water from that jacket into the exhaust pipe. This is what makes it an open cooling system. That particular problem was addressed in a video.
@@thedutchmanandthedigger1500 Which video? I'm thinking of doing this to my jetski so it can have a closed loop cooling system.
Without going back over them I have no clue which one it was.
Hi
How hp for centrifugos clouchehts
They are rated fpr 15hp.
Looking good! Did your engine have a threaded output shaft on it ?
Yes they have a threaded output. You thinking of building one.

I've used motorcycle engines in buggy builds on a few occasions with good results .

Why 2 centrifugal clutches?
Each clutch was not rated high enough to handle the hp.
How the cart going

I was going to do the same thing I got a 440 cc jet ski engine but this week I'm getting a 250 2 stroke
Coil.....not CDI
