If your carb is coughing at steady speed, you might have an intake leak. Inspect your spark plugs to see if they are burning evenly. If not, the lightest or cleanest plug will be on the cylinder that may have a leak.
The 107 was dual vented. One line went from the bottom end breather (behind and below the oil pump) to the back of the air cleaner and both heads vented through banjo fittings into the back of the air cleaner as well.
Inside the rocker box covers there are a couple of umbrella valves (directly above where the air cleaner mounting bolts go into the heads. Sometimes those umbrella valves get stiff over time and don't seal well or sometimes one will roll and not seal at all. This will cause oil mist to transfer into the air cleaner.
Prolonged high rpm operation will result in oil carry-over into your air cleaner as well.
On a dual vented engine, you can plug off the top end breathers all together, or you can route them away from your air cleaner.
Not to sound like a serious dumbass! (Ease up with the rib shots people) Why is it o.k. to do this? DV
And if it was to bedone what would the problem be in the long run if any?

Don't block off the lower breather!
I blocked off the top end breathers on my 107 and haven't had any problems. The dual vent was a precautionary measure when the 4" engines first came available. The concern was that the increased piston diameter would create more crankcase pressure than the single case vent could handle.
Thanks DV. Question answered.
Yeah, that friggin state but did I mention I'm not stationed (as in didn't want to live there in the first place) anymore!!!!you can take the dog outta california but cant take cali outta the dog!
tree hugger!
nope... don't listen to to what I read... I read what I read.
And yes sorry about the confusion... MY BAD OH SAD!!!
beano, most of the info posted here deals with the newer SSW motors (Super Side Winder). Your 02 doesn't apply except for what sul mentioned about head breathers that are available from Wimmer.
Our new SSW motors don't have these breathers but your motor does.
Just some differences in the model years that we sometimes forget to mention.
Good luck,
Ray

Exactly... I forget too often about those differences.... need to be reminded every once and a while. Good thing Sul always gets some twisted pleasure out of reminding me of my mistake.
I have yet to meet you... but no. And maybe this year... I would like to ride down to a VA/Tenn ride. Now that the bike is done, my #1 goal is to put on as many miles as I can. I'm sure work and home will interfere but we'll see.
