125-200cc CR 125 & WR125 Spooge

Took our 2012 CR125 and WR125 to the power wash after our first couple of hours on them and noticed a great deal of spooge on the tail pipe and rear fender - is this common or are we running too rich?

Also, do the 2012s require an adjustment of the Powervalve?

Thanks in advance -

Yes.

I no longer have spooge running, and the silencer is pretty clean (for a two stroke)) at the tip, but the white plastic gets blackened pretty good. Don't think there's much that can be done there.....

Magic eraser works great to clean white plastic.

Our CR 150 spooges a lot when putting around trails. After an MX race or MX practice runs... no spooge. Ever.

Mine will spooge up if I'm riding the tight stuff and don't have enough sections to run it it up on the pipe for long stretches... I can always tell how hard I got to ride if the bike comes back with very little spooge on the rear fender or the back of the exhaust...

Spooge is generally a result of too rich a pilot jet. I suggest a 35 pilot. A step richer slide. If you can start the bike in cold weather without the choke or immediately take the choke off on cold morning then you are too rich down low. That is where the spooge comes from. I use Maxima K2 at 40:1, very clean burning. Use Race gas or a mixture of Avgas and Non Ethanol Premium.
Do not use E10.

It's an exhaust-gas temperature thing. With proper jetting When reving hard with the PV's open and the engine scavenging optimally the oil pretty much all gets burned before reaching the silencer junction or tailpipe. On-and-off the throttle at lower RPM's and there's going to be unburned oil left. Not much you can do about it but clean it!

You can jet it properly. Don't think you can't greatly reduce the problem.

Went for a ride the other day but as there was a large frost about I raised the needle one and went up one on the main, never touched the pilot !
Boy was I upset with the drool I had to clean off as the day warmed up

Just look at this mess

Where do you ride that thing, up and down the road? Does anyone on this site ride their bikes in the dirt?

Yep ride it down the roads and lanes to my local riding spot often
Use it for as many enduros H&H I can fit in during the year but always clean it back to the best I can get it as I do all my other bikes lol
Looks like this once I get there

It is quite simple, if it isn't burned, it ends up in liquid form in the pipe. It is an exhaust-gas temperature issue. Rich jetting results in low exhaust-gas temps and incomplete combustion! Good jetting can reduce the problem. But I think it is misleading to suggest it can be jetted away by doing this or that, when it has a lot to do with how and where an individual rides.

Same here..... My bike gets filthy when I ride it, but it always goes back in the garage as clean as I can get it........ I do it because it's new and want to make sure I can see if anything came loose during a ride.... If it's full of mud I might miss something...
