97 XP With ADA head and more
Got a ski with a motor out of it (got it that way) and need some sugestions. Lots of things on this ski kinda toss a red flag.
It has ADA heads, F/A's, a aftermarket pipe (can't remeber the name right now), and a carbon fiber rotory valve.
First thing I did was go through the carbs, it has stock jetting PTO 147.5 main, 65 pilot, shinny silver spring and a 1.5 needle and seat. Mag has same except 142.5 main jet. That has to be lean for the parts added. I havent checked how man turns the adjusters are but its still gotta be lean. Mikuni BN-40I (SB) carbs.
Then I pop the heads off and I notice some damage and one Wiseco piston 779M08200 on the PTO side and one 81.89 ELKO 2096 with AUS on it(Sea-Doo?) piston on the Mag. Is this OK ? I have never done that and not sure if its OK.
So lets just start there. I am not that savy on the Sea-Doos carb settings so I am sure there is a tried and true setup for jetting and I can just get those parts set it and fine tune it then be done with that. As far as the pistons I am lost on what to do.

sounds like the previous owner squeeked a piston and only bored one cylinder and replaced one piston instead of doing both. that would explain the jetting differences...I think
Its got a Carbon Fiber Rotary valve? I gotta see pix of that...never seen one.

I know it has been worked on the one cylinder for sure it has marks like a shop bored it a bit. Mabey I should match both cylinder bores?

It's better to put a stock RV in there i heard that they break and then end up ruining the engine.
