    Removing it won't improve a thing. It's a tank vent. Nothing more. Has no effect on performance.



    I can explain it to you, but I can't understand it for you.

    Powdercoated '87 frame, extended swingarm, YZ fork legs, ATV tire, 14/55, XT350 tank, spliced quick-release seat, disc brake conversion, beeg headlight, beeger rack, Lizrdcooler, Lizrdventz and bunch of other stuff all covered in invisible ink.

    If you are talking about the round cannister on the right front frame, it is a charocoal accummulator for the fuel evaporation and vent for the carbureter and fuel tank. NO effect on performance at all.

    So many myths about the canister that they've become accepted as fact. I gotta do a writeup on how the thing REALLY works.



    It's one of those rare instances in which a picture isn't worth a thousand words, but a simple diagram with couple of arrows, is.

    Thanks, Rich. A lot of folks don't fully understand tank venting. If I were a better draftsman it would be pretty easy to show how a Cali system ultimately functions identically to a vented cap and nothing more.



    Well maybe a little more. It also helps keep your garage from smelling like a refinery storage tank.



    I giggle at the claims on certain other bike-specific websites of magical power increases after "DeCalifornicating" the canister. Prolly the most common bewlchit indicator of who really knows what in all of motorcycling.

    Remove it and you have an excellant mounting area for one of lizrdbrth's oil cooler kits.

    LOL. I miss my canister. I often hug it.



    I'm looking into some really lightweight, compact scooter units which anyone else who hugs their canister can install in a different location on the bike.

    The day will no doubt come when motorcycles will be checked for smog, if not every other year then at least when the bike is sold. Hopefully the older ones will be grandfathered in and exempted.
    Long live the internal combustion engine!
