951 in my 750sx freestyle buildup

Whats the deal with the shaft lengths with sx, sxi, and sxipro?

SX and SXi should be the same but the SXi Pro is a bit shorter I believe.

I need to give up about an inch and a half off of my stock shaft. looks easy, cut and re thread the end?

I think a 650 driveshaft is shorter than a SX. I think that's what I used in my carbon sxi pro to set the motor back. Then you could use a 550 or sx coupler to get it to the right length.

So, I dropped off my crank at the machine shop. I supplied the rebuild kit and he said it wont be more than 300.00 rebuilt, trued and welded. Sound like a good deal? Im also looking for a sea doo 3 wire rectifier so I can have a charging system.

Three wire rectifier? I think even the old 587 rectifiers have four wires.

He needs to finish that!!! im on him everyday he was tellin me to finish my superjet and i did get on him!!!!!!

Fred, after reading your post it sounds pretty ghey that you were "on me" But I laughed anyway.

Time to shift my attention back to this project. I should have the crank back within a week or 2. Im also looking at a billet R&D intake with reed stuffers to make life easy, and found a micro touch programmable ignition for 99-01 sea doo 951. Im wondering if the micro touch is a "full standalone" or do I still need the other Sea-Doo electrics to make it run? Its either that or go with the Advent system. The price is right on the micro touch, I just want to be sure it will work by itself.

go with the advent

Brian great work you will get it this year! Won't you ? lol

as long as my car dosent blow up again I will be able to finish it this winter. I just got used to driving an all wheel drive monster that barely gets traction on a dry road... Looking forward to learning to ride an equally overpowered ski this summer.

 

[the WaTeRhAwK]

wow, a friggin GP 750sx...lol

 

[Brian_216]

Im just doing this for fun. Not really worried about racing, or getting the max speed out of the ski. just a rec rider. and that brings me to my next question- since Im not going to be out racing, should I spend all the money on the advent ignition or get an MPEM and front ebox and do it cheap?

 

[Waternut]

What's an MPEM?

 

[WFO Speedracer]

Multi Purpose Electrical Module

Im back to working at this. Motor is back form the machine shop and will be put together this weekend. I just bought a decent TIG welder so Ill be able to do all the exhaust fab myself (after some practice on aluminum) I still need to purchase a splined 951 PTO hub and a sea doo shaft to fit it, and have it welded to my shaft on a lathe so she turns true. Glass in the front mount and then its a weekend full of wiring and plumbing hopefully this summer it will be alive!

 

[snowxr]

Don't bother with the shaft welding. Use a kaw coupler and XPdi pto. They use the same kaw rubber damper.

 

[Brian_216]

exact fit? I have the one from a 99 xpl and its close but not quite a perfect fit. This could make things easy!

 

[snowxr]

XPltd uses a different pto. Use the pto from a XPdi.

 

[Brian_216]

anybody want to sell me an xpdi coupler?
