Here it is. Yamaha X2.

[ADDict]

I just got Rag's old engine lined up in my hull. Here are a few pics of the install. This baby is bolted in and aligned like it's time to rip!
I'm installing my engine tonight, and hopefully will be taking a test ride soon.

WTF, call me.

[shawn_NJ]

Oh s h i t!!!! VERY IMPRESSIVE!! You made it look way too easy!

[cattledog]

you two are a great team, so you used the stock engine mounts, and custom bedplate, x2 driveshaft?

[cattledog]

you guys will have to sell a kit become rich and famous, just think i knew them when they had kawasakis

Where the hell has this bedplate been hiding at?

[ADDict]

Where the hell has this bedplate been hiding at?

I used a jet ski haven plate I had been running with my 780. Just took some cutting and grinding to make it line up the way I wanted.

[ADDict]

OK we got it lined up, then went head first into it.
Here it is with my 650 out of my SJ and a stock 650 pipe. I'm going to water test tomorrow, then put my factory pipe, and a 46SBN on it. Hopefully it will run good enough to keep me happy for long enough to put something nice in it.
:love:

[madscientist]

you rock will, nice use of john's hard work

[ADDict]

you rock will, nice use of john's hard work
I agree. Best use I could imagine of Johns hard work. I would like to thank him personally. I would also like to thank Thong Bandit for winning it, and flipping it immediately. Also thank you for holding the freeride that allowed us to get a bed plate.
Now that I've kissed everyones ass possible, I'd to thank Matt and I. I haven't tested this yet, but I'm pretty damn sure it's going to work great. John put a lot of hard work into it, and so did I. Can't wait to try it.

[w-nut]

nice work , ill have to keep on eye on this thread and see how it goes.
i think ill stay with kawasaki . i heard a rumor today that someone will be bringing out a billiot kawi pv cylinder up 1000cc next year . they are testing them at the moment

[crab]

sweet guy's

[ADDict]

That would be killer man!
I just didn't have the cash to rebuild the 780 right now, and I DID have a 650 SJ in the driveway. Plus, I just really wanted a yamaha driveline. Hopefully it will work out for me.

[ADDict]

have you tried an fpp headpipe in there yet? thats the snag that put this project on hold for us last year

[shawn_NJ]

It fits in mine, but you cannot remove the headpipe without taking the motor out....its that close. Headpipe must be installed when you slide the motor back onto the mounts.

[crab]

Thanks Crab! Get that e-mail?
yea, thanks

[dbrutherford]

I kept saying it wasn't that hard to do...

Now would someone please donate one of those pillet powervalve cylinder SJ engines for me to use?

I'll be trying it out tonight. Just wanted to put this setup in that I know works to try it out. I'll try and set the FPP in there tonight after a test run, and I'll let you guys know.

Patience young grasshopper. I'm about to head to the lake. I was up until around 4:30AM this morning working on, so I had to get a LITTLE rest. I'll let you know shortly!

I didn't think it would be that bad, and it wasn't. Just took some thinking. Seriously, I started out yesterday morning going damn, I'd like to get that engine in there sometime soon. It took me from about 11:00AM to 6:00PM to get the idea worked out, by 9:00PM the plate was modified to work and I spent the rest of the night installing it.
I never thought I would hear the brap before the night was over, but I did! I'm on the way to the lake to give it a try now.

It is. The idea was that ANY Yamaha engine will now bolt right it. I blew up my 780, so I decided I would go ahead and get it ready for the Yamaha.
As soon as I can I'll be putting a 701 top end on the ski, and a few other tricks I have planned.
The 650SJ motor will hit hard with the right mods. Compression, timing, larger carb, FPP, etc.. I think I can get plenty out of it, then as I said I'll go to the 701 as soon as I get the chance.

[RAGS]

still a lot better then a kawi 650 :poke:

[ADDict]

The word is good. I rode about an hour on the X2 this afternoon with no problems. Everything stayed exactly where I put it.
No vibrations, etc.. It's SMOOTH. Of course it's lacking in the power department, which I knew when I was doing it. Like I just posted, the 650 will hit hard with a few more mods, and power wasn't the main goal of this test. Now that it's ripping with the 650, I'll concentrate on getting a bigger engine, and atleast more power out of the current engine.
I'm running way to much impeller, and not enough ass to turn it right now. Unfortunately I don't have any other impellers to try out. I think it will spin it good though with my fpp/46SBN and a little more tuning. This thing is going to be SWEET before long.
Here are a few pics for the haters!
BTW it sounds pretty good with just that stock 650SX pipe in it. Can't wait to try a B-pipe.

Proof and point, the kawi pump is just fine, no need to change it out just get the right prop for the power delivery.

Now children! No fighting in my thread!
However I will agree that in stock form, the 650SJ is WAY snappier and has more torque than the 650 kaw. I know if you can get your 650 kaw to hit good, that this 650SJ engine will slam. No doubt about it.
There are a lot of guys rocking the 650's in there SN's and they will scream. I'll probably end up buying some cylinders and just putting a 701 top end on it and have a fakie-701.

What about pass out first and then shiat my pants in my slumber?

I am going to go test ride some guys CR500 tomorrow. He wants too much for it but I figured I could weasle a ride on it. I am guessing the lamey is got some power like a 500 MXer then huh?

[cattledog]

Pretty damn close. I never imagined it could make the WPS seem like a kids toy. You got that SXR motor in yet...or have you sold all your crap? I would love to ride an X2 with a Lamey stroker in it. That would be badass!

All you need is one coupler, as it mates up to the yamaha. Stock motor mounts, drive shaft and pump.
Ski was great to ride, no problems. Just needs more power. As soon as I can afford it I'll be picking up some 61X cases and a FPP manifold. I was hoping I could use this Coffman mani I have, but it doesn't work. I hate to cut it up, but I think I can clearance it to fit. Just hate to ruin a BRAND NEW coffman manifold.
The fpp headpipe DOES fit in the hull with this setup. It's in there now, but it lacks about 1/8" to tighten completely down to the manifold. The back of the headpipe rubs it, and won't let it seat completely. Again I think I can clearence it a little and make it work. I just can't decide if I want to yet. I need to just sell ALL of my kawi stuff and buy the parts to make the 701, and a fpp mani for it. I'm just a little too broke now as I haven't worked in almost a month. Just went back out to work yesterday, so we'll see what happens.

[X2guy]

Was trying to figure out how to mount mine tonight. I was going to build this engine for a SJ but after I build the engine there will be no more $$$ for the part that floats. Might as well break it in in the X2 next year. Did you make spacers to mount the cases to the bed plate?

[WB1994]

Did you make spacers to mount the cases to the bed plate?

I was thinking about this a while ago. If the coupler height is too low and spacers are needed to get it to the correct height , instead of stacking washers , I was going to use aluminum handlebar tubing cut up to make the correct size spacers.

[WFO Speedracer]

I strongly suggest that whatever you do you replace those four case bolts with studs,they are only 8mm bolts,they are not going to take a lot abuse,the stock Kawi engine mounting bolts are 10mm and so are the stock Yamahas.Remember most of us are beating the crap out of these hulls ,yes even me!

[crab]

Fairly certain Will just bolted the cases to the plate with longer bolts and no spacers.

[WFO Speedracer]

From my dealings with this the case bottom mounting to crankshaft centers on both were damn near identical,I will know a little more tomorrow if the bedplate shows up then.

Your no fun.

[WFO Speedracer]

Your no fun.

No you can't go to 10mm thats why I said use studs they give you 30% more clamping force than a bolt,proven fact!

[X2guy]

Yeikes!...I was thinking that the case bolts could be used. The only thing I thought could cause a problem is that all the engine torque would be transfered to these bolts.
WFO why do studs give you 30% more clamping force. I'd also be concerned about warping the cases by tightening the bolts enough to secure it to the bedplate.

[Kaveman]

I will give you two dollars then.

If he paypals you $2 then send him a pic of a pile of dog sh it.

Good idea. I'll look into that. This isn't the ultimate solution. I'll be grinding the ribs out, and glassing in some plates for the yamaha mounts. I know that will work, and will be plenty strong for me. Just not a bolt in solution, like the plate I'm using.
As for now I just used longer bolts, no spacers but I've got spacers being made and on the way shortly to fill the gap. Also keep in mind I'm using a 650 for testing purposes, not the most torque, haha.
Also, does anyone know if a 650SX or any other driveshaft is a little bit shorter..? I was thinking the X2 shaft doesn't fir other ski's for some reason. I want the engine about an inch further back. I'm having issues getting the FPP chamber in there because of length..

[ADDict]

Sx is 6 inches shorter, move the pump back perhaps.

Well thats shorter than I had hoped! I need to save up the bucks and get a fpp manifold. I had been using a couple different ones (not fpp,) on the 780, and hoped I could modify my 650 coffman to fit but it's just not going to happen. Not without damaging it possibly beyond repair, for something I don't even know will work for sure.
I need a 701 FPP mani in a bad way. Just can't cough it up right now. Hopefully I can have one soon, until then the X2 is parked. I can't stand riding it with no power. I'd rather watch video's of my good times.

[crab]

They are around, I am picking one up at Pismo as well, they get good money.

[ADDict]

They are around, I am picking one up at Pismo as well, they get good money.

Yeah thats the ticket. No way without major mod's to make it fit the coffman.. I had hoped it would, I guess since it fit my coffman Kawi mani as well as others I thought I had a chance.
Looks like I'm going shopping. Have to need parts when I'm BROKE..

Will, if you use a shorter drive shaft I think the head pipe will hit the hull brace/hull.

Get another Puddlepuzzy coupler and have it bored and rethreaded to fit the Yamaha crankshaft,that should give you your inch you are looking for ,you may have to use a spacer between it and the crankshaft though.

[yamanube]

What about an adapter plate to bolt a kawasaki pipe to a yamaha cylinder?

[dbrutherford]

No need, just use a FPP Yamaha manifold. Then you just use any three bolt head pipe (Kawasaki style) and it will bolt right up to the manifold.

[yamanube]

Yeah but shlt you can get kawasaki exhaust (generally) much cheaper and much more abundant. Ive got a plate to put a kawasaki 750 manifold onto 61x/701 cylinders and would probably be pretty easy to recreate...just thinking out loud, it seems 750 pipes are easier to find and fit into an X2 than B pipes.

[dbrutherford]

You can still use 750 pipes. You just need the FPP Yamaha manifold that makes the head pipe to exhaust manifold the 3 bolt pattern.


Post a pic of your adapter plate. I have only seen ones that made it where you could use Yamaha exhaust manifolds on Kawasaki cylinders.

[shawn_NJ]

Will, hopefully I'll be able to get the motor out of my lightweight this weekend. If I do, I'll snap some pics for you and take a few measurements.

[dbrutherford]

Here is the plate that lets you use Yamaha exhaust manifolds on a Kawasaki cylinder.


He is claiming he has the opposite.

That there is a plate to use a Kawasaki exhaust manifold on a Yamaha cylinder.

I just don't see the point when all of the FPP Yamaha exhaust manifolds have the Kawasaki three bolt top pattern anyways. Then you just use a FPP head pipe and any chamber of your choice.

Because "just getting" an FPP manifold is not always as easy as it sounds and buying a complete 750 can sometime be just as cheap/expensive.

[ADDict]

I agree on the ease of finding a cheap Kawasaki pipe. As for the adapter plate, in something like an X2, you want all the room you can get. With the 701 in the hull, I'm having to smash the side in a little of my chamber to get it back to the headpipe. I think I would just buy the FPP manifold. They are $205 brand new. Then if you decide to go with a factory pipe, it will work. Otherwise if you get tired of switching around pipes, and want to get a Factory headpipe and chamber, you absolutely cannot get the headpipe to fit. The FP manifold is just universal.
On my old 780, I ran a Coffman Kawasaki manifold, with the Factory headpipe. I tried to fit a Factory headpipe onto my Yamaha 650 Coffman manifold, and it wasn't happening. If your sure you don't ever want to go with the Factory pipe, you can get a 650 Coffman manifold. It uses the exact same 3 bolt pattern all the Kawasaki's do. I was able to pick one up brand new from Coffman recently at a VERY nice price. I bought two actually.

Thank's db I have never seen that adapter plate option before.

[dbrutherford]

I agree sometimes parts are tough to come by. The adapter plate I posted a pic of is for sale by Blowsion. I thought of getting one for my 800 SXR engine and then using a Power Factor pipe. But being I already have a nice FPP setup, I will just use that.

I would still like to see the pic of the adapter plate you have. I also believe EME uses an adapter plate on their 777 Polaris engines to use the Power Factor pipe.


I know exactly what X2Addict is talking about though. I saw a mariner 650 manifold once used on an X2 and it wouldn't let the FPP B pipe head pipe mount onto the engine because the head pipe hit the side of the hull. However with a stock Kawasaki 650 exhaust manifold, it fit fine. The Mariner spaced the head pipe too far out from the engine. And it wasn't the wacky Mariner/FPP 750 rotated manifold for the 750 wet pipe.

You might be able to make the bed plate angle the yamaha engine slightly for more clearance. Yet then you run into problems with the flame arrestors hitting the other side of the hull.
