Hello,
I have seen some posts concerning a rough engine, but not specific to my case. Hoping for some help...
1992 Yamaha Exciter II 570
December activities: Cleaned the carbs, replaced spark plugs, new belt, cleaned sheaves...
Issue: Sled is very responsive when starting up. Runs great. Eventually, after the engine is nice and warm, the sled loses all power and idles very low. Almost to the point of dying. If I am on hard packed snow then I feather the throttle and give it a little push to get it moving, but it still runs rough. Normal idle is around 1,500 - 1,800 rpms and after warm it drops down to just barely running. I have got to believe that this is related to the no power.
Any help would be awesome.
Thanks.
Sam
