Hi I'm working on a 1995 Polaris explorer 400 two stroke, and I had planned to put in a new wiseco piston and rings and just hone the cylinder. I think it overheated at some point and the rings did not move freely in the old piston. The clymer manual I'm using doesn't really have much information as far as honing the cylinders on a rebuild, but I've been doing some reading and it seems that some cylinders are plated with some type of chrome or nickle plating but I'm not sure how to tell if it has been plated and if so with what. The Wiseco instructions say that their rings cannot be used in chrome plated cylinders. Any information on this topic would be greatly appreciated.

Maybe someone with more knowledge than me can comment on Polaris 2 stroke specifically, but on nickel plated cylinders in general you're fine to give it a quick hone.  Really needs a good crosshatch to seat the new rings.  The nickel plating just means you can't bore it oversized without having to plate it again.  Interesting catch on Wiseco rings though, i've never noticed any advice against chrome plated cylinders.  Probably because the rings are softer than chrome and will just eat down.  Then again, I don't think I've ever had anything with chrome a chrome plated cylinder wall.

      2022 Hisun Sector 550 Gas gauge stopped working
      By Clydaho
      2022 Sector 550, 414 miles on it and the gas gauge reads empty.  I topped off the gas and it didn't change.
      There is no fuse that I could find.  No access at the gauge cluster.
      Wiring on the top of the tank looks good, properly connected.
      Could the sending unit in the tank be stuck or broken?
      Has anybody removed the tank lid?  Any tricks?  
      Any other ideas?
      Thanks for any help,
      Clyde

      Looking to buy a new SUV
      By Gwbarm
      I have been exploring all the options available, so many, its hard to choose. I have kind of narrowed it down to the Honda Pilot, Subaru Outback, and Kind of looking at the Outlander, although its a little small,  the new one is nice looking. Just wondering if anyone has any recommendations or gripes with any of these rides. I have driven Jeeps for the past 25  years and they have been great, but their price point has gotten to high. Expieriences good or bad would be helpful. Thanks!

      1997 Yamaha Kodiak 400 fouling plugs
      By Drillbit
      Hey all,
      I need some input on a problem I'm having with my Kodiak 400 that keeps fouling plugs. First off, I've done a lot of work to this thing, most of it all in good fun. Brake work, cv joints, u joints, carb kit, checked valve lash, compression good, changed all fluids, etc... My problem is it keeps fouling plugs very quickly. I can put a new (manual recommended plug) in and it starts right up, runs great, idles great, picks up good. Doesn't stutter at all. I ride it for 1/2 a mile, it cuts off and won't start back up. I let it sit overnight thinking maybe it got to hot. Try to start it the next day, nothing. Put a new plug in, fires right up, runs great for another 1/2 mile or so, dead. The plugs come out and look carbon fouled with dry black soot on them. I don't know if this is a fuel/air mixture problem or a ignition problem. A couple of things that I noticed is I never need to pull the choke out to start it. Also, when it starts it automatically idles high like an automatic choke would do, then it comes back down to a good idle. Also I noticed that the air/fuel mixture needle valve screw does nothing when I adjust it in or out. I can screw it all the way closed and the motor still runs and idles good. Any advice would be greatly appreciated. I'm almost leaning to a ignition breaking down the plugs??
      Thanks!
