Up-Tite carb filter

[gasgasman]

I looked at the 7602 filter, but you need tools to access the filter.
The Up-Tite has a scew on cap.

For the guys concerned about water crossings.
Here's a set up with one way check valves on the breather hoses.

Girard,

I've used that setup and its fine. All the filters and check valves get a little bulky when tied up in back of the carb though. For average water crossings up here(river maybe 30 ft across) you don't seem to need the check valves if you split the lines and run a pair high. I never got water in the carb that way, but I can see the check valves being a good thing for more extreme water.

I wouldn't worry about the routing for water crossings. We get some deep water and mud up here and the stock routing (out the linkage) works just fine, just keep the throttle open! I've been in some water above the airbox with no issues other than wet boots.

I do like that filter idea though, looks cool!

Have to disagree on that one. Its the length of the water crossing, or the time the lines are submerged rather than the depth. The carb will draw water (and dirt) if it has enough time to generate a sufficient vacuum. Beleive me I've been down this road and the result was a jamed needle/stuck throttle from sandy water drawn up the vent lines. I've been splitting my lines and routing a pair up since with no problems.

The "trick" in regards to the vent hose routing for water crossings is, to put a vertical loop in the hose so there's an air space in the hose that blocks water.

Splitting the hose ends keeps mud from plugging the hose.
The splits ends vibrate while riding, shaking the mud loose.

Like GMP said, eventually water will get into the float bowl.

The reason the bike stalls out in water is because the vent hoses are blocked off by the water.
The float chamber has to have atmospheric pressure to "push" the fuel through the jets. No fuel-no run.

I use the one-way valves from Kevin's on my lower tubes, I don't see any need for the filter on there since it is one way. The white filters work well on the upper tubes when put in the airbox.
I occasionally use small lawnmower gas filters on the airbox routed tubes when I don't feel like waiting for yet another small order. I don't split the ends, I cut them at an angle, the old school method.

I'll answer my own question...

While I see a button for the product line, it doesn't launch any such page.

After "extensive testing", I had to relocate the filter to the air box.

Two things were happening.
1)The filter was getting saturated with fuel,due to the mounting position lower that the carb.
2) The filter clamp kept vibrating loose.

I have mine mounted betwixt the swingarms.

No problems thus far.
