Some oil in the exhaust when the engine is idleing is normal but if it is fouling the plugs it sounds more like the oil pump is set to rich

It is fouling the plugs,but only when i try and start it.When i do get it started the oil dos clean out and the z runs great,but i have to kill my self to get it started.The 700 twin has alot of compresion when cold and is a bear to pull over,but cant beet the perfomance.Thanks for the info.

Are the plugs getting fuel fouled? There shouldn't be that much oil while just pulling it over. At least not enouph to foul the plugs. Look at the oil pump. There should be a line on the lever where the cable attaches to and a line on the pump housing. Those should lined up with the sled off and no pressure on the throttle. At least there were lines on my 97 670. Or you could be dumpin too much fuel into it. It will come out the exhaust looking black cause its cleanin all the soot out of the pipe good luck!

Did you just buy this sled?
Perhaps the old owner put too much oil in the engine when storing it for summer?

Not the Muffler bearing. It's the whoozit valve!! JK It is loading up with fuel! you have Carb problems! stuck chokes or floats, maybe needle valves, take apart, clean, change needle valves they are cheap, Doo a choke adjustment according to manual specs clean the choke plungers etc.

Your floats could be stuck. I had a sled that unless i shut the fuel valve it would flood the carbs when I went to start it. Also look at the sync of the carbs not sure if it would help but it won't hurt anything. And the fuel pump is wicked simple. Take it apart and check it out. Could be toast. Should be able to find one on ebay for cheap. With it being warm out probably don't even have to choke it.
