Hey everyone,

I figured this would be a good place to post updates on my little project. I'm currently refreshing my 93 JS 750 that, for this thread, I'll [endearingly] call "Betty"...you know, good old reliable, timeless.

Edit: Compiling this has got me a nostalgic scrolling through old pictures... So to your delight [or not] you also get a brief history of me and my ski - a kawi love story. Don't fret i've done you the favour of highlighting this fluff in green. It provides no real substance to the "build" but let's be honest, you're going to look anyways.... we'll call this nostalgic and/or history.

The intention is for this build to be fast and furious... well relatively. As context im expecting the birth of my son in less then a month and am fortunate to have the whole summer off with the wife... soooo I need this to be ready to ride.

This is the ski in question, a 93 SX painted a burnt orange colour (Canada eh) that I believe to be synonymous with the early - mid 2000s ..... Also that's my dog Summer, she's rad. The keen eye will also notice the sweet dolly that this thing is riding on - more on that later.

Here is the same ski moments earlier, this photo is strictly here to appease me #nostalgic

The above photos were captured at a small private lake in Quebec, this ski is the biggest hoon machine there, that's OK though :D - not necessary:

Here's an underhood shot, most of you likely have a more aware eye for these things then me but from what I can tell it has : Wet Factory Pipe, Head, Reeds , ride plate, grill and neglect.

More on that aforementioned dolly, It was one my brilliant *facepalm* solutions to move the ski around the shop and in and out of the shed at the lake. This stroke of genius came when cruising the Canadian tire and seeing a super sale on the bad boy .... For those who aren't familiar with Canadian tire think Harbor Freight x Lowes x Pep Boys, it's a place of glory and mass identity confusion.

A more completed look, this is the straightest these wheels ever were destined to be..... More on that shortly.

One weekend while riding I broke ( well re-broke) the handle pole while riding on the Ottawa River. *insert unnecessary but nostalgic shot here:
20180804_092454~2.jpg

The re-broken pole was, to me, a catastrophic issue as I vacation the following week, it was on a large lake i've never ridden. With no options in the local classified i had to act fast... Synopsis of the repair.

To be fair this repair still stands but it's too much of a liability if it decides to let go mid summer... plus the pole on this 750's seem too long to properly get your weight forward.

In the above picture you can see that there is some tin riveted to the top of the pole (typically hidden by the pad) this is note worthy as it's witness to a previous repair, done by the last owner.

****** Here's where things get both historic and nostalgic for a moment.... and generally unnecessary******

Circa 2010, the day the poles broke. Also the first day I ever seen or rode a stand up. Pictures below is my self and the original owner being general degenerates.... Later that day I broke the pole, a later irony in my life *facepalm*.

After I became thoroughly addicted to standups, Chris, the other above, left his old 550sx for us to play withfr the next few years. I rode the 550 weekend after weekend for years, never gave me trouble.

It did the deed no doubt, Factory pipe and aftermarket pump..... also had a custom 2.5 Gallon fuel tank ;):

****** End of Unnecessary Tangents ******

All that to segway into the handle poles... I got it in my mind that I need to build a pair, once I get an idea I can't shake it ..... so here's the plan:
20190306_104905~2.jpg
For the more detailed oriented users: I did do a quick mock up in Solidworks to confirm the weight,in 6061 it should weigh between 9-10 lbs. To my understanding that's less then stock so that's AOK by me.

Look that damn cart again!

Version 1.0 collapsed after it met a flight of stairs...... So i beefed it up and added a pair of amazon wheels., it's hugely improved but a massive waste of time and energy.

I blew the Ski apart and took it over to a local car wash to blast out all the years of neglect, quite humorous granted we have at least 3' of snow still on the ground:

I started going over the hull, found one previous impact i wasn't aware about but generally . It's in great shape!

Last month I tossed around a few livery ideas for pole on my IG, clear winner was 1B.

Originally I was bent on doing a vintage inspired livery (such as 3) but decided to do a retro + contemporary homage instead. The plan as it stands is do option 1B and use white turf for the tray and bumpers, the pole with most likely be white as well.

I happen to have some blue paint in my inventory but am torn if it's going to look good or cheap, my inclination is to just use what's on hand but am open for comments?

Finally got a moment to look at this again, previous weekend was a wash.

Photos tell all:

Took a moment to get the design sorted but i think I'm in track now, slight deviation from my sketchy sketch.

Utilises the stock bushings and pole limit contraption.

Why not.

I hope to advance this pretty quickly now that I got my direction settled. Also in the interim I ordered a care package from @JetManiac .

Pole looks good but you sure its not worth buying something already built? Might be worth cruising the X/PWC Today/Kijiji and Craigslist for something you can drop in. Not certain of 750sx bracket size but modding some bushings would be way easier than creating a new product. That would let you run most poles available (Assuming the base is larger than a SJ, not smaller)

Anyways, excited to follow along

For almost every pragmatic reason you're probably right. Ive seen others elude to using SJ poles, I've taken (albeit not very thorough) look around and have only found a stock pair of sxr pole.

That being said I enjoy building my own stuff, if it fails, I accept that as a learning experience. Time will tell on this one lol.

Had a few more hours to look at this tonight, fairly pleased with how the pole is turning out. A keen eye will notice a splash of the colour to be.

Had some time to move this along today:
20190324_123857~2.jpg
The current paint had some wicked blisters in it so I worked on getting those areas flat. I then layed some fiberglass in a couple damages areas, cleaned the engine while waiting for it to cure.

20190324_152925.jpg
A local fabricator got the poles welded up today so I was stoked to run out and grab them.... I've never welded aluminum and this wasn't going to be the project to learn on.

Preview of welds:

Overall I'm super pleased with the new poles. They are -2 in length so I'm eager to see how they effect the feel of the ski.
