    WERA belly pan requirements

    Folks (wera experts)-

    Prepping Aaron's 400f for wera competition next spring and ...

    just read the rulebook and have questions about the belly pan requirements. Are two strokes required to have 5 qt. capacity? This would be seriously difficult on the Bridgestone for example. Does anyone have or know of a pre-made belly pan for the Honda cb400f ? Do most people just use fairings with a rear dam?

    Peace
    Karl

    I can't believe any of the two stroke guys are following the 5qt requirement unless their fairing with a rear dam would hold the five qts. We can try my Tanner belly pan on the cb400f to see how close it fits if you want.

    And with no WERA event at VIR in the spring we've got until April before we'll have to worry about it.

    karl,

    you know how much fluid that you have to hold? if so, then build it to hold that and some more, in a craftman like fashion, and you will be fine. hell, i don't think my tanner pan would hold five quarts.....lucky for me, since my engine only has 2 quarts in it.

    silly....imho!

    How much does the Tanner pan hold before trimming? Calculating the WERA requirement I get -

    5 quarts = 160 fl oz

    160 fl oz = 289 cu inches

    289 cu inches = this varies but it could be 12" x 12" x 2" or 10" x 14" x 2 and 1/16"

    This is roughly the size of a brownie pan. I have a Tanner pan at home (at work right now) and it's rectangular with 3 or 4 inch tall walls on it. To fit it to my Suzuki GT500, I'll make some shallow notches for the chambers and run steel strapping up the sides to bolt it to the frame. Some chicken wire on the inside bolted to the strap brackets holding in a oil absorbent pad or two and I should pass tech just fine.

    Here's a picture of Tex's CB350 with a Tannermatic pan:

    Until it comes loose and you get black flagged for something flapping around under your bike.

    That's the purpose of the chicken wire I mentioned - make a pan shaped liner out of chicken wire to sandwich the absorbent pad between the chicken wire and the pan. Secure the chicken wire at the top of the pan where it's bolted to the bike.

    dunno craig.....i think some 100% silicone jizz would work wonders in keeping it in place.

    I have a can of spray glue, I got it at the hobby shop, its for gluing Styrofoam sheet together, anyway I spray some in the pan slap an oil pad in and go, once a year or so I tear it out and put in a fresh one, works great,
    I did follow a guy once at Loudon that was losing his piece by piece it was mildly distracting,
    At mosport they would complain if you had a belly pan, made it hard for them to see if your oil drain was wired, but I understand this year they have changed there rules and now require them
    Wera seemed to like the tanner pans never had a comment from tech on it,
    They are really big on steering dampers and always check for that!
