foam triangles
I think this has been covered before, but the two little foam triangles in te air box, what do they do and how essential are they? Mine are getting a bit manky and fragile, so wondering what others use/do, or just replace - at £5 a pop seems a little steep!

I may be mistaken but I believe they filter air for the vacuum side of the carbs!macdee wrote:hi bvgBigVeeGrin wrote:I think this has been covered before, but the two little foam triangles in te air box, what do they do and how essential are they?

Re: foam triangles
there must be better price somewhere (David Silver?), even though prices in UK are higher. Reasonable price is up to 3 pounds.
For example:

e: I´ve just realized David Silver is not an option :-)

Re: foam triangles

David silver is £6.60 each inc VAT plus delivery. A Dutch site is €2 each plus €10 delivery. Think I'll pop into the honda dealer down the road, at least you wont pay delivery charges for the oem part etc etc

Re: foam triangles
just buy some air filter foam and cut it to fit, iirc its less than 5mm in thickness.
HEY YOU GUYS!!!!!!
Re: foam triangles
Yep or you can get a bit of filter foam from an aquarium shop. If you get prper filter foam from eBay (it's cheap enough) you will have loads, enough to last you 10 years.

Re: foam triangles
good stuff - wasn't sure if there is a certain 'grade' / density / type of foam that is critical, or whether I'm over complicating this!
btw £6.0 each at the honda shop

Re: foam triangles
You don't want anything too course otherwise crap will get through
They should be lightly oiled too which helps catch fine particles.
