Way too slow Brad. On my Dial-a-sh&%%ts I have more compression in the hood compartment than the cylinder. From bottomed out to full rise was (and there is a reason I say was) was only 5 lbs on one side and 8 on the other. I went with Brads full setup for my wc motor. The etching brings a very nice cosmetic appeal but what I was really impressed with was the fit of all the pieces. Another thing is his desire for my product to work. You dont get that much anymore.


So my problem is too much compression 160 at 2000 feet I need to do squish but have not yet. I would like to make these work even if it is a pain I replaced all the o rings and they are not leaking yet :-)
 
I have a mechanical reverse on my new apex & it has held up to the 350 hp for 1000 miles. I cant see much of a difference between the polaris and the yamaha reverse components. So if anyone really wanted reverse on the edge 1200 they should consider the putting it on after seeing the success of the yamaha. I would never of considered it before seeing it. I had to fabricate the reverse operation to function from the ebrake lever/ cable on the bars, very handy location.

I think the main reason I strayed from polaris is more power, and reverse.
And the myth of yamaha dont break, is just a myth!! You will have greasy hands with any brand.

Yeah but theres turbo yammi's and then theres sleds like yours! The Yammi's are tough and most people that just put a turbo on or SC once dialed they dont have to touch em, when you get into the full mod category its a whole new ball game!
 
power,need more???

Well guys Im putting twin turbos on my 1160 watercraft , Im sick of Apex and M1000's on Boost ,next year there is gonna be a new sherriff in town, Ive been watching this post since Lynn started it and lots of guys enjoy these motors which in my book are totally awesome for the reliabilty and power aspect ,so Im going to try and take it a step farther with the help of some other motorheads, Ill keep everyone posted as I continue.
 
I know theres a couple turbo w/c motors but no one seems to talk about them. Are they junk or is it so top secret that they cant even talk about how cool they are.;) Its a conspiracy I tell ya.:D
 
600HO sled carb boots/900 Sled Reeds?

Will the 600HO boots and 900 Sled reeds work in a WC motor.
How well are the crankshop pipes fitted when you get them? I have an edge chassis, and since they must have built quite a few sets of these the fitment must have gotten pretty good by now.

Those boots and reeds will work.
Regarding CS pipes fittment, as of late I cannot say. A few years ago, it was a mixed bag. Talk to Brad (1200psi) he can fix you up.
 
Has anyone ever tried a complete later model mach z ignition with the RER and got it to work. I figure 1200PSI could handle the machine work pretty easy,just like to have reverse is all, not that i have it now. I think it would be awesome to have such a killer motor and then be able to maneuver it around the shop and off trailers and such.

Any Thoughts, Experiences, I'd give it a shot, be the guinea pig so to speak if someone could machine a housing and make a retapered flywheel. I guess someone else would be a better test mule, i only have a set of cases so far lol
 
SL900 W/C engine

A customer just brought in a 1996 SL900 watercraft with some ignition/wiring issues and hull damage. He also wants me to build up his 800 REV over the summer. He asked if I would be interested in trading this W/C for some of the work to be done on his sled. The W/C is basically a POS.....but I'm wondering if this bottom-end is the same as the 1050 & 1200's you guys are talking about. I looked on eBay and a few other websites I found on google and they all listed the 900, 1050, & 1200 as basically the same motor. Is this true?? If so, I'll make the guy an offer and part out the rest of the engine and hull.

Here's what I have so far:

Complete ignition system and wire harness for a 1996 Ultra RMK

'07 IQr 440

1996 SL900

Oh yeah....if the 900 engine is the one I need for my own DIY Watercraft project, this UBR600 w/CS pipes, carbs, electrical, etc is for sale!!.....and the 440 engine, too!! PM me if interested!!

I'm going to ride this sled one more time.....then the 440 and 121" track are GONE FOREVER!! Hoping I can start on a 1200 W/C project soon!!
 
I believe thats the one you want. Maybe 1200psi or 4Z can confirm this. Be sure to inspect the cases for bearing movement. 1200psi can hook you up for all your machine work to the case and other goodies you will need.
 
I will be parting out my 1200WC sled-let me know what you want or need I have 1500 PSI pipes and CPI pipes two differnt heads, 2 sets of reeds and carbs etc. etc.
you guys can have the first chance. I will put this all up in swapmeet in a few weeks It is a 50/50 fuel engine @ 3000' 250 hp 169 ft pnds torque non VES cylinders

JUSTPINIT,
the 900 bottom end will work for building a 1200. you need to remove a little more material when fly-cutting the case. you need to clearence for the piston skirts on the intake and exhaust sides. the 1050 and 1200 cases do not need clearence for the pistons, but if you get a good deal on the 900, it is also a good platform to start from. the crank journals are identical as are bolt patterens. the only real difference is piston skirt relief between the 900, 1050 and 1200. if you have Brad do the machine work, just remind him it's a 900 and he'll get you hooked up.
 
Thanks guys!! I pm'd Brad. I'll double check with him to make sure I have the right cases to start with, then try to do the deal on the complete W/C ASAP.

Euge....I'll be talkin' to you soon, I'm sure!!

Yes machine work is needed if you want space for the piston in the 900 case, the best is to copi the older 800 non ves case, this has exact the same upper case half (shape)as the W/C case.
You can also as a quick fix cut the piston skirt 3mm, dont cut to mutch, if you do you will open up the main exhaust port when piston is on top position.
No problem to run with shorter pistons.
 
Should be the same as the racer as far as mounting and pipes go. Like I said before 1200psi has done many 1200 racers and makes all the parts associated with the swap.
