Have a carb off an '07 Big Bear 400 that sat a couple of years, probably more. Friend asked me to clean it, which I did, soaking the jets and spraying out all of the ports with carb cleaner as best I could. Replaced o-rings, needle valve & seat, tweeked float level. Bike starts and idles well but doesn't want to pick up above 1/4 throttle. That would appear to be in the slide needle range. Main jet is clean, needle is clean and straight, diaphragm good. It seems I saw (in a diagram) a port that comes into the slide needle area from the side. This would be in the carb body between the main jet and the throat of the carb. I would like to soak the carb in Gunk Carb Cleaner, the gallon paint can with a little basket. Curious what Mikuni uses for bearings and seals in the throttle shaft. I'm guessing HDPE or Delrin, or maybe brass; not sure what effect Gunk would have on the polymers. Has anyone actually soaked a carb in Gunk?? First hand knowledge, please, and what effect, if any, on the carb. Pulling the throttle shaft out would be a last resort. Getting the butterfly screws out and staked back in would seem to be a nightmare.
Thanks
Jim

I picked up a 2017 Polaris Sportsman 850. The previous owner rarely rode it and it only had 53 miles on it (10 hours). I believe the Polaris break in period is something like 250 miles / 50 hours or something like that at which point they suggest doing the first oil and fluid change. My question is should I do it sooner than that? I believe this was manufactured in fall of 2016 so that means the fluids in there are 3 years old. Maybe that isnt a big deal and it is still fine to wait until 50 hours, but just wanted to check
