found this on fleebay watercooled head

anyone tried this?

All of the liquid cooling options have one downfall alike..... the water pump!

Liquid cooling isn't really rocket science.... liquid jacket around the cylinder, liquid coolant passages in the head, radiator, some hoses, and some way to push the coolant around. Nothing but the water pump need be a moving part. Everything else is relatively easy... most of the water pumps available are either small electric pumps (which eat up all of the available capacity of the lighting coil) or mechanical pumps that come mounted on other engines....
 
I just don't see a point in water cooled on a blaster, but i sandblasted my jug and left it bare without paint. This kept it allot cooler.
 
Just ordered one and a spare insert, we will see how it goes...

We can run it on Neil's DT200 bottom end and pump.
And test it out with the FLIR Gun.

His prices looked very reasonable.

Ive always wondered if the oil injection pump could be used to pump the coolant ?

i was gonna say you could setup a dt watercoolin pump..... but i dono if you can do that with the aircooled cylinder over it. the fines may cover the coolent passage.


something like this>?
Yamaha Blaster High Performance Liquid Cooling Kit

I dont see how the oil injection pump would ever flow enough fluid. It would be way to restrictive. The water would set too long in the head and boil over.

i cant wait to see what the results are iv wonderd if they made a diffrence or not

the dt and blaster side cases are exact same. the blaster has rubber plugs and a solid plug over the hole where the watercooling pump bolt in. look just above the blasters oil injecting pump and you will see what i am talking about. i havnt converted one of these to LC but i know if you had the parts its not hard.
 
It would be worth it to test the oil injection pump on the bench , run it with a drill motor and see how long it takes to move the amount of coolant that the system actually uses . you then have a baseline . at that point the pump could possibly be modified to flow more coolant , or a custom water pump housing / impeller could be adapted to run off the injector gear drive . I wish I had a Blaster engine to experiment with , it would be pretty cool to make that happen . what the blaster needs is a CNC made jug with water jackets like the Banshee has , so you could bolt on a 240 stroker thats liquid cooled . and a Head with of course the changeable domes , it would be a really sweet set up

a few years back, i remember reading up on a commercially available water cooled head for the blaster, that worked off of thermal circulation....
the head heats the water, that then becomes less dense and rises, forcing the cooled water from the radiator back down into the head, and so on and so on.
not sure how well it worked ?

same as our very old coal furnaces here were called "gravity fed" and had no pump to circulate the hot water thru the radiators
just heating the water circulated it, they worked like that for decades, and some may still even be ?

naw ? seems like painting them gold and now even powder coating them is the new "cool thing to do"
you mean that doesn't make them run cooler ??? LOL
 
Using a pump to move the liquid isn't necessarily needed. I've seen conversion systems for 3 wheelers that didn't use a pump. It's call thermosiphon, the Model T cooling system was like that.

ME TOO!!! when we get the LC head it probobly wont be long before she gos on my bike for a test. Im thinking the old man will probobly get the flar gun to test it. WE may be the only ones who ever will!!!!! Now thinking of it we should of took one of his KTMS out to get some pics of a lc 2stroke for comparassion, Both those pics are air cooled motors^^

i assure you the little oil pump would need LOTs of work to flow coolent. you are onto something about trying to use the shaft and gearing up a setup that ran off it. I do think even making the setup on the actual blasters lc spot would be more doable.
 
Honda Oddysey's back in the day had that " bubbler " thermosiphon kit available , worked pretty good . I think a DC conversion would be best and just run a electric fuel pump to move the coolant .
