Looking for a Renegade-style airfilter kit?

I know we have plans on getting the open airfilter kit from Firebolter on AF1 and D-Rider was looking into the possibility of laser-cutting... but.... I got impateint and went hunting. I'm still keen on getting the Firebolter template and building an airkit for the experience/fun but I also ordered one from this chap over on www.RSVZone.com.:

His prices are a bit much for my tastes
Being a tight arse that i am i made my own. £52

Plate £2.00
Filter £40.00
Filter oil £5.00
Carbon fiber sheet £5.00

Not as refined but still does a good job and looks reasonable

You can still get Rene Airkits new.
We have moved to Portugal, our Tel/fax is 00351289703547
Our New site is still under construction, we are sorry for the inconvinience.
For further info please email us at mail@renegade-products.com

You can obtain (i think have them fitted too) them via Southern Cross as well if you ask Don.


That does look tidy, Paddy :smt001

Agreed... and I know the chap is a mate and all, but I phoned twice to place an order and was told to phone back in 4 weeks on both occasions.

We're all getting impatient.

Decided that getting a template sent from US of A was not really going to save me much so I've been watching evilbay.

Just bought a MilleR airbox for 99p (postage is a bit of a b@@ger at £15 though).

This airbox has a higher lid than the Falco one .... I'm guessing it won't fit under the tank ..... but I'll try it and if it does, I've got a bigger volume. [BTW the base is the same part number]

However, it does give me a couple of further options:

1) Use it to create a template to sort out an evo-style airbox.
2) Use it as a template to sort out a Renegade style airbox

.... after which I'll probably flog the airbox as I'll not need it any more.

I've been mulling over the Rene and Evo designs as I'm concerned about what appear to be some weak points of each of them.

Evo Advantage:
  • Engine sucks from a big chamber of filtered air - no great restriction to mouth of TBs. This air has come from the front of the bike - not hot air from the engine
Evo concerns:
  • Well only one really ..... how can I be 100% certain that it is sealing completely against the underside of the tank - especially when the engine is sucking hard?
    The filter is only over the normal ducted air tubes so any leakage past the seal to the tank is a potential disaster.
My solution:
  • Durrrr ... don't have one ...
Rene Advantage:
  • Doesn't use a restricted sized airbox
Rene Concerns:
  • 1) Air Filter is directly over mouth of TBs - Engine always has to suck through this restriction.
    2) Filter sits on open plate - heat from engine can rise up and the engine sucks hot air that could be quite different to the measured air temp. Probably not an issue while flying along the road but would it be an issue in traffic?
    3) With the engine sucking hard through the filter mounted over the TBs, the weak point seems to be ensuring a good seal between the base of the filter and the base plate. Not sure that the mountings I've seen on the various solutions convince me that the seal is 100% guaranteed.
My solutions:
  • 1) None - feature of this approach
    2) Make the base plate as big as possible to fill the hole and minimise the problem - can't be completely solved.
    3) ...... I have a plan ..... this is my biggest concern and I think I have an answer.
Anyway, I'll let you know how things go when I get round to it.

Have you been thinking about this by any chance? :smt003

For 1), what is the risk/concern? The sucking is from the piston moving down so there is no 'strain' on the engine. Or is the concern more of a starvation issue? I think the filters in use are designed to ensure the engine gets what it needs. Any starvation would show up on dyno graphs.

I have also wondered about 2), because in the car world you get intercoolers to avoid this problem.

For 3).... I await your answer :smt002

Isn't Firebolter on the AF1 forum doing a run of his Renegade-esque carbon fibre plates again?

No.

He's making patterns from which you can fabricate your own .... that was what I was referring to at the beginning of my last post :smt002

Answers to your problems

1 Engine always sucks through a restriction regardless. It still has to pass through some ducting and angles before it gets to the filter (all restrictions)

2 Only a minor issue when at a standstill. Hot air may want to rise, but when moving forward, the hot air has no time to get up to the throttle bodies because of the rush of colder air from forward motion. A simple precaution is a few spacers under the forward mounting bracket (increases the gap between frame and tank)

3 Good quality window seal. I have two layers and it has been an effective seal in the 2 years that i have had the filter fitted. When removing filter for cleaning The plate was dirty and dusty on the outside but the plate inside the filter was as good as it was when i fitted it

Yes but usually through a big plenum that smooths things out - seems the rene scheme is a bit like breathing through a scarf.
(Though I know it does seem to work well)

Yep - I know it's not a problem when moving but what if I end up on a longish journey through a big congested city on a hot day - that would normally be bad enough - just don't want the thing to run like a dog too.

Sounds good .... but I might still pursue my plan for this ....
