Do i really need an air-filter !!!!!!!!!!!!!!!!!!!!!!!!!!!!!

autofetish · Post by **autofetish** » Tue Jul 21, 15 6:48 pm

Firstly Fuel is injected at the blue line so the filter has to be above the line.

I have order muti filters. The best i got is the oval K&N filter.

Q. Does it look to small ?

Q. you got a better idea

They are never gonna flow enough air to fill those cylinders ............even if I they were UNDER the blower

You only need to stop large airborne particles & any poss debris, like a dust cloud, I would spray some light oil on a foam element gauze & be done with it Will.

Will, drop an Email to Nelson Race Engines or someone like that and ask what they do. Nearly every video I watch if theirs they are running FI.

All that work you've done and no filter.........first time you drive past you neighbours dog you'll wreck the engine!

Ask in a bike shop mate, there's a million different shapes and sizes of filter to fit inside airboxes. K&N type, oiled foam, etc.

I have buddy and the VF700F bike filter pictures above is the biggest that will fit in the hat. (Which I don't feel will let enough air past it)

Think I will go with Adrian's ideal and make something to hold the corse foam.

Will have to be strong to not get sucked down the blower

Will,
Just be careful about how much suction is created from the blower. I could virtually hold a yellow pages on the scoop...

If the filters not well secured, it will be gone/ eaten

I never ran a filter, but did run a blower filter

Do you have a gauze filter over the blower inlet, they sell them at Good Vibrations.

inlet gasket G-2014 or similar

autofetish · Post by **autofetish** » Thu Jul 23, 15 2:01 pm

Yes I'm Running 2 x blower gasket gause

Mark what's you view on all this filter stuff?

I'm really stumped and spend hours just staring at it

If it was me, I think I'd just use the gauze, that'll stop anything chunky.

Filters pretty much just make your bores last longer... Now I don't want to sound negative, but is long-term wear likely to come into play before catastrophic failure?

autofetish · Post by **autofetish** » Thu Jul 23, 15 9:46 pm

Now I'm not intending on doing any desert rally stages

It is a mild engine running low boost

How long will an engine last with no air filter ?

Come on everyone what do you all think

Dave81 · Post by **Dave81** » Thu Jul 23, 15 9:57 pm

Think you'll be okay with what you have.

You've got the throttle blades plus the gauze, so bar dust, you should be okay.

Just don't tail gate........

You could always put some fine stretchable material ( like tights but not prone to combustion), over the metal gauze for fine particle filtering.......it'll be a PITA though to do checks for blockages/clogging!

Mossy68 · Post by **Mossy68** » Thu Jul 23, 15 10:06 pm

Will. I think as soon as you introduce any foam/material type filter you will cause problems. That thing is gonna SUCK !!!

I ran bell mouth carbs on my bike for years. Firstly with a mesh gauze like you have , but later with nowt. On the road and strip.
Must say I was paranoid without the gauze though.

I personally would stick with what you have.

Roger · Post by **Roger** » Fri Jul 24, 15 3:29 pm

Apart for the "offical" answer, i cant see any practical way you can run any decent filtration in that Will.

Gauze it will have to be.

like the others said, and thing more restrictive will likely get sucked in. That would do your engine and blower much more harm!
