carb. vent hose check valve

[john r b]

Hi Guy's, Hoping some one can direct me to finding a check valve for
the carb. vent hoses. Ive seen the PC unit & Pro Circuit ones. Any other's?
Thanks.

Why do you want a check valve for them? Air needs to be able to travel into them to assist the bowl breathe and fuel comes out of them when the bike goes upside down.
I fitted a filter from these guys http://www.7602racing.com/prod_t6cf.php
As I noticed after my last very sandy dusty ride some sand grit had made its way about halfway up the breathers.

I use the same breather system, I clean that little fiber every few months. It's away a little dirty....I would think that if the filter wasn't there that crap would end up in the crab.

I apologize for my incorrect wording,but Yes this is almost it. I've seen one very similar only it was made from Aluminum and orange of course.Thank you Nate.

IMHO the check valves on the gas tank are not a good idea.
I have been nearly stranded when one failed and caused the gas tank to be pressurized and flood the engine.
Luckily I noticed the bulging tank.
Now I just run a hose with no valve of any kind.
You can add a plug into the line if you dont want fumes venting into the garage.

Thanks Dreamer.I'm referring to the vent lines below the bowl near the linkage.
