It was a brand new gauge, I may not have held the throttle wide open when testing though. If I get some spare time tonight, I'll compression check the other ski just for another set of numbers. I'll do it the way I did the first ski and I will test with the throttle wide open.
My garage is too small for both ski's so unfortunately it is one ski at a time. The second ski is on the trailer outside. I was planning on tearing it down regardless so both ski's are identical in service requirements and timeline.
I hope to have requested pictures to you this evening. Do I need to separate the cylinders from the crankcase for best view? I guess they will need to be removed at some point even if I just have them honed.
Have you ever rebuilt a carb?
For your carbs get MIKUNI kits ONLY. Go one at a time. Carb 1 and carb 2 are different. So one at a time mark and then slowly turn in both your high and low screws. Record how many turns on each. It may be 1/2, or 5/8 of a turn. Or could be 1.5. I mark the carb body on the edge of the screw hole with a small sharp chisel and very lite tap of hammer. Then disassemble with camera Pics for reference. And let soak in the carb cleaner.(a gallon can pre purchased from auto parts store) I know Napa carries carb cleaner in cans. I'm sure most the others do to. Soak it over night works best agitation once in a while helps but not to hard. Then rinse with hose and blow dry with air if you have it. Then use carb cleaner spray to spray through every office you see. Then follow the drilled return mod under "how to's" and clean again with spray cleaner and reassemble. Reuse your old needle/seat spring.

Short answer, No. I did just rebuild a carb on a Ryobi blower but no where near as complicated as this set. I picked up two Mikuni carb kits from Bay Area Powersports. I had to return the aftermarket set to them and just exchanged for this SET that includes genuine Mikuni kits, needles and seat.
Finally got some work in and was able to break down the cylinders and power valves. It appears the installed power valves have already been updated. I have all screws undone, do the valves lift up out of the slot to the cylinder? I cannot get mine to budge. I have attached cylinder pictures to determine if I am sleeved or not. Thanks for the help.
Location: slower lower Delaware,second home on lake Conesus in NY. keep a 93&94 vxr pro there.
Yes both jugs are sleeved.
If you've removed the screw that holds the power valve bushing in then you may have to lightly pry up on the valve to pop it loose. Cyl walls don't appear to bad may be able to hone and put in new pistons/rings.
