125-200cc Power Valve Drain Tube & Plug? '06 WR125

Hey guys,

What's the story with this drain tube and plug that are coming off the power valve assembly on my '06 WR125?

Are you guys removing this plug completely? I'm assuming its supposed to catch excess spooge and you would remove the plug from time to time to drain it? Is the plug supposed to prevent water and dirt from entering the tube and traveling up into the power valve assembly?

I'm referring to the bottom tube coming off the PV assembly below.



It has this plug on the bottom of the tube:



Are you guys leaving the plug in the tube, or have you ditched the plug all together?

Thanks,

Ed

Most of us leave it plugged and drain every few hours. If you leave it open you will get spooge leaking out on most everything down wind of the tube. The older cylinders had a much larger circumference power valve that lets quite a bit of spooge/gasses past into the chamber. The lower vent collects the spooge, upper vent lets the gasses escape.

Right on, thanks Walt.

I was wondering too. My other Husky motors, 125, 144 & 300, were all plugged on the engine, no hoses.
My 165 has the hoses, but no plugs After Walt's comment I ran the upper one up under the tank and plugged the lower one with a small wire nut and cable tie and stuck into the skid plate. Guess we can spray into the upper hose and catch the drainage from the lower as necessary.

I always ran mine open per FBF on the 02 model so I just continued it on the later ones

I wouldn't spray anything into the breather hoses. Some of what you spray will make it down into the exhaust port and could get into your cylinder that way. I don't think there is any real issue with plugging them off other than it is nice to collect some of the spooge that would normally make it through your pipe. Just have to remember to drain it periodically or it just fills and runs the extra through the pipe or out the upper breather and onto your bike.

What a mess! The upper tube I stuck under the tank blew spooge, so I plugged it with a little bit of old sponge. Don't like the idea of dripping and blowing spooge everywhere I go either.

Thought I read here somewhere to spray cleaner in there periodically I could be confused

I run it down and hang down similar to a carb overflow.... jetted right not really much comes out.... nothing that Mean green and the pressure washer dont clean up
