Does anybody have any info. on the wr200. I heard that in theory you could put the cyl. and head off of a wr200 onto a blaster bottom end. True or false. Sounds like a cool mod.

 

very, very false...

 

Well it was worth a try, is there any way of putting a water cooled cyl. on the blaster.If not I was considering getting a 240 big bore kit, does any body have sugg. where the best place to get one and how much!

 

AlaskaTRX: Do not be so quick to judge. If you look at the Blasters right sidecase, you will notice a water pump casting. Obviously the Blasters case/bottomend/tranny was used in a water cooled bike. I'm not sure, but I belive the WR200 uses the same topend.

Check out these two pages for some more info:

It is a proven fact that the Blaster shares parts with the WR200. It is possible that the top end from that motor would bolt onto a Blaster bottom end. Keep in mind I said its possible. I *think* that the water pump would also fit, but it would require case machining, many expensive parts and a lot of time. But it would have a very large cool factor if you could make it work.

If you'd like to try, the clyinder/head off a WR200 can be had at a reasonable price from a salvge shop. Water lines are no problem, and an automotive heater core could be used as a radiator. The water pump is the problem area.

There is another solution to the water pump problem. Electric water pumps have been used on watercooled 300EXs.

 

For the 240 kit I would go with CTracing. Their upfront price looks a lot more expensive than the others but it comes with everything. Pipe, carbs, reeds, porting, headmods, airbox adaptor. The other companies onlycome with 240 sleeve piston and match stock ports.

Mine has also been very reliable.

Just a thought..

Why don't you try an oil cooler instead of the water.....water is better because the jacket is right in the head....but for ease of installation an oil cooler might work just as well to keep the motor cooler than stock. I can't say that I have ever seen one mounted on a blaster....But I bet it can be done just fine. Good luck.

 

You cannot oil cool a Blaster because it is a two stroke and the oil is mixed with the gas on two strokes. Or in the case of the Blaster oil is injected in the carb and mixes with the gas there.

Guys
Yamaha has made many variations on the 200 engines; a lot of these have never been seen in the states because of your EPA type legislation. There is a DT200 water-cooled trail bike still in production I think outside the USA, These engines are all very similar as can be seen by the redundant water pump housing in the side case. this housing also actuates the powervalve used on these watercoole rockets. If you are serious I can look through my brothers microfiche sets (he's a Suzuki and Yamaha Franchise dealer) and come up with some comparisons. If you find a water-cooled WR or DT you might as well use the radiator etc of it as well as throwing the entire engine in, sell the old air cooled relic !!! for parts.

Engine kits, check out Trinity at http://www.trinityracing.com/
They are really onto it guys.

These are all very interesting ideals. I was looking into the wr200 idea to see how much more could be had out of a blaster engine. Oil cooled is also an interesting idea. I'm also considering the big bore kit from trinity or ctracing. Like you said some come with just the sleeve done and others the whole kit. I have got a fmf pipe and silencer already and a set of boyessen reeds on my ride . Its a little more peppy then my wifes stock one. How would the 240 kit keep up to some of the bigger ones like 250r's. I think those one of the best around.

I think that the best way to cool a blaster is by cooling the fuel. I have drag raced cars for the last 10 years and my son wanted to drag his 2000 blaster, but just didn't have the power. On my drag car I have a cooling can that an aluminum fuel line is colied into that I fill with dry ice. It drops the fuel temp at the intake by almost 40 to 50 degrees. So I created a canister on the blaster that does the same thing but the dry ice is sealed in the can. The engine runs much much cooler than imaginable. Plus you can run a higher compression since the temp of the fuel is what cools the piston. Lots of work but it's worth it. Let me know what you think.
