Wanted to check in and see how it's going over here?

I got some aluminum tubing to up the stinger end to 2" and got my water box in, and will be slowly mocking things up as I have time. Also will...

Same here. Life keeps getting in the way...

I just ordered the same waterbox today. Looking forward to seeing how it will fit as things slowly move forward.

Ditto!

I've been checking back for any updates. I am buying the same waterbox shortly to modify mine to a 2" exhaust on my ski this winter and have been studying your pictures, my ski is a front...

You guys do realize this is a six year old post, right? :moon:

Wish I saw this sooner at least to comment, I'm running a 550 Coffman waterbox, which works well.

However, one of my winter plans is to increase to a 2" exhaust, using the same SinkDoo water box...

Man I guess I got lucky having just gotten a good used one for $260.

Got some motor mounts.

Looking for straps still, not sure what a set is worth versus just going to ebay...?

Looking for a set of motor mounts (older JS style, not SX style if they really are different).

Also looking for a complete set of straps: waterbox/tank/battery.

Thanks!

Found one...




SXI Pro, maybe others...? Has a better timing curve and RPM limit than my current one.

Found one...

Looking for a good used 3738 CDI if anyone has one! Thank you.

Looking for a good working 3738 CDI if anyone has one? Thank you!

This! I used the Watcon plate on the conversion I just completed and it was SO worth the money!

PM sent re: pump.

Edit: Sorry, I thought I was in the Vintage Skis section. If someone wants to move it, feel free to do so.


As a followup to my previous thread, 550SX Cracked Pump, I've removed and disassembled...

Looking for a good condition pump for a 550 SX, or more specifically, the shoe/wear ring and stator sextions. No impeller needed or desired, bad bearings okay as long as the parts are good shape....

That's understandable... the guy I bought it from was super anal about the ski, it is in mint shape, and he said the original owner kept it indoors in a climate controlled, heated floors garage. The...

Last question that I can think of, regarding pump bearings; when I had the pump out, the impeller seemed to turn smooth and tight.

I don't know the history of the pump but since the ski is mostly...

Thanks for the replies guys... I thought about having it welded but wasn't sure if it was a good idea. Assuming the stator vanes are good, I'll find someone who can do aluminum. Dang, my wirefeed is...

Hey guys,

Recently picked up a 92 550SX in near mint shape. I haven't ridden one since I was 9, now 20+ years later it's like learning to ride a bike again. I absolutely love it!

Anyway, I...
