Thanks Tony, again! :face-icon-small-coo Forum member to the rescue yet another time. Good catch.

Got a problem? NO PROBLEM! Crank, pistons, power, weight, clutch, oil-cap, driveshaft, clutching, belt-drives, gearing, venting, YOU NAME IT! The forums will be on top of it and most likely come up with an affordable quality fix from its devoted members.

Show them the Cat rear bumper that fits on your Pro. Looks good sitting next to the new YamaCat.

Forgot about the M bumper I put on that I had laying around. haha

Any Yamaha parts that fit? Might as well go for it all.

Bought 2 one for the sled and one to dissect. Don't think the dissection is necessary because you can see how it works just by looking at the under side.

It has a lot more resistance to suction then the polaris one does when operational though.

I bought 10 today. One for every piece of equipment I have plus one for my red polaris undies. I taped it on. Have to make sure my undies are vented or I will run into big issues.

Good find TRS!!!! Thanks!!!!

This may be a good solution to a POSSIBLE problem. What amazes me is how quick guys will accept something like this. I have yet to see a post on this thread that shows how the Doo cap works better, more reliably than the Polaris cap. I guess proof of a problem and proof of a solution isn’t required before a guy will buy 5 or 10 of theses. Amazing! I need to come up with something like this to sell. It would be easy to make a buck for sure! LOL

I think I will start watching the Doo forums for a while. There could be a run on Doo oil cap sales noticed, and some one will deduce that Doo has a cap problem and many are replacing them. If that occurs I will jump in and let them know that the Polaris cap fits well and is a winner!
The internet is so much fun! LOL

Does anyone know how this vents?

and does it vent both ways just in case the tank gets warm like in the summer? also, the doo tank is not by the belt and is not subjected to as much belt dust and dirt like the POO cap.... Does this look like it can be plugged up with belt dust?

Time will tell. Time testing needs to be done. The passo does not vent both ways, it is a one way check valve.

DUCKBILL !!! QUACK QUACK.

According to this photo..the Doo cap uses a super simple Duckbill-Valve ...

So I see it working very well to vent at very low vacuum and not when rolled over. Time will tell. But it sure is an easy alternative and cheap to buy..Certainly will not be any worse than what is on there.

The only problems I could see is if the valve is not compatible with the oil you are using OR dirt gets sucked into the valve...Both unlikely.
