\"must contain a maximum of two holes 25mm dia\"
 

So as I see it you don't HAVE to have ANY! But how'd you drain rainwater (or oil in a catastrophe) if you din't have any?
Makes sense to have at least one at the bellypan's lowest point!
;)

That's why I reckon its a typo and it should state "minimum" instead of "maximum".

acu regs state maximum two holes of 25mm

I've sent a question off to demodue@ducatisportingclub.com regarding this and I'll report back the results.

As Tetol says the ACU requires that you have to 25mm holes that are plugged for dry races and open for wet races and there one heck of a lot of wet races at club meetings even when its bone dry, if the clouds are threatening rain then the wet race board goes out which means they don't have to stop and restart the race if it rains.
Normally you have one hole at the front and one at the rear to get rid of water under both acceleration and braking.
The support vans in the paddock such as A&R racing carry spare grommets for plugging 25mm holes if you happen to loose yours although I have used tank tape before now, with one end folded over on it self to form a tag, this makes it easy to remove in the collecting area if need be while holding the bike up with one hand.

Ian, I think you have missed the point here mate:puzzled:

nobody is on about any cheating - its clarification of DD rules, that are not quite 'per' the ACU rules we are asking for.
Straight after the agm, we had an email in February confirming a few points, also promising a full update of the rules. We havent had this yet, and its April

Whilst we appreciate all the hard work that has gone into getting the series off the ground:) it is now very important to get clarification - we dont have long to make any changes/additions/mods with 2 weeks to go.

Here is what we could do with being confirmed:
eg:
airbox: is this a sufficient catchcan for oil breather - as holds approx a litre, or do we need additional catchcan under the airfilter housing
mudguard - to have or not, as on monsters it is incorporated into chainguard. (acu rule 5.14 Mudguards are not compulsory)
do we have to have a top chainguard - as well as the acu sharkfin underneath (acu 5.15c)
Stickers - we have sorted ours - leaving room on forks & bellypan as suggested, so not worrying unduly about them.

Not wanting to have egg on our faces in 2 weeks time.

Alan & CK :)

CAn't help on them all, but I've been informed by Mike (MW) that we definitely do not need to run a top chain guard or rear hugger. We obviously have to have the lower (shark's fin) chain guard though.

Strictly speaking that is not a fuel breather. Your fuel breather is built into the tank cap. That breath you mention serves to vent the overflow caused by overfilling the tank. This will spill over into the recess where the cap is located. It's the same as my MiniTwin racer - I don't bother routing this into a catch tank - I've had no scrutineering issues with this. You can do one of two things:

1. Remove the pipe and forget about it.
2. Route the pipe into a catch tank. Anything will do as long as it's resitant to petrol. For the non-return valve phone Alan Russell at A&R racing - he'll probably have them.

HTH.

UR welcome.

That's correct. It is. The holes should be no more than 25mm in diameter.
