‘91 Superjet 6m6 to 62T/61x swap

you should change the rear exit exhaust tube, Rad Dudes sells the whole kit and get a RN waterbox. Although the season has started, I would make it a winter project

Why?? If its got a pipe then it wont matter.

Quick update - I was able to get my entire ski together in time for the 4th of July and have ridden every day since 6/28!

I got my hands on a set of clean dual 38s, had a local friend help me pull the flywheel on my 650 and swap it into the 701 with a 61x stator, and was able to align the coupler on my own.

The ski runs great but I need to fine-tune the carbs. I am running factory carb settings and jets:
-High: 130
-Low: 70
-115 gram spring
-Front High Speed Screw: 1-1/8
-Rear High Speed Screw: 1-1/2
-Low Speed Screws (both): 7/8
-Still not getting a rusty brown color...

I ran it with my 6M6 CDI, because the oem 62T CDI that I got from a guy on Facebook had no spark. I definitely feel like the ski is being held back by the lower rev limit of the 6M6.

If anyone has a working 62T CDI that I could purchase, that would be great. Thanks for all the input here, you guys helped answer a lot of my questions.

How big of a difference does this make? I have a ported and piped 61x/61x in my 95 SN. Wondering if its worth upgrading the whole exhaust system to the larger 96+.

Not a big difference. Only worth it if you are already doing glass work like footholds imo.
