I have an 98 700sx,it has 7000 miles on the clock.Carbs have been rejetted years ago.Mods this year reedspacers,silencer mod.After ridding 300miles in munising last week.I started to get overheating on low snow condictions,This has not been a problem with this sled before.coolant comes out the overflow.Heat exchangers are warm too.I ran with 5 polaris sleds,and they were ok. in these snow condictions.Motor runs great.as long as i run in the realey deep stuff im ok.its mostly the plowed logging trails.any thoughts here

the silencer mod will lean down your jetting some, I would check the plugs at all three levels, and adjust if needed, also have you changed your coolent in 7000 miles it is most likely broken down some, and new coolent might help. you could check your water pump just to make sure it still moves freely. bad antifreeze will damage alot of stuff.
