Hi all, just wondering where i can buy some Pipercross foam to mod my standard filter element - looked in the demon tweeks catalog but can't find any???

The usual answer is not to bother - the std OE filter is the danglies.

You can get pukka HRC foam for a fiver a sheet but it only filters things bigger than shrews...

Yeah, the standard filter is great at what it's supposed to do; the PiperX mod works well and can be cleaned/washed & re-used; in saying that, some might say that it's actually a bit more restrictive than standard.?
My personal experience of it for the past 4 years (I think), is that it works fine with both the standard can, as well as with a Yamamoto half system + can! I've not rejeted my bike as yet since fitting this foam, nor after fitting the Yamamoto pipes, as advised by Dyno man!

Have you tried contacting Pipercross directly? http://www.pipercross.net/" onclick="window.open(this.href);return false;
I think the foam we need comes in 1 square foot bits?

ah - i was under the impression that the standard filter might be holding my bike back a bit but i'll stick with it if u guys don't think it is? i've got a tiger full system with carb slides drilled and standard jets oh and its an nc30, thanks for the advice, Martin

It may be the standard jets that are holding your bike back a bit, not the air filter; my feeling regarding the PiperCross one, is that it performs just as well as the OE one, with the benefit of allowing it to be cleaned/washed.
Best thing to do is to get the bike on the Dyno for a power run (about £15), to see what the fuel mix is like. Does the engine rev cleanly from say around 4000rpm to redline?

hi - the bike runs well from 2000 to the redline. When i'm in 6th at between 5 and 6krpm and i roll on the throttle it does splutter a bit but not that much - the rest of the time its fine, dyno time is the next thing on my list but the nearest dyno is 70 miles away!! bit of a pain eh?! i'll get some bigger mains and see if there's any power difference, thanks for the advice
