airbox, where does it breath ???

How does a VTR breath with a snorkel without any hole down ?
Does the VTR takes warm air thats flows between the engine and airbox ?



Is this a normal configuration ?

Re: airbox, where does it breath ???

Yeah its a normal configuration...believe it or not.

I guess the developers at honda discovered something that we dont quite know. And I think that was those 2 huge carbs sitting underneath the air box require a **** load of fuel to make the hawk run the way she does, so why give it any more air when all that would have to happen is to give it more fuel.

****...stock settings on the hawk are only good for 130 miles a tank. can you imagine what mileage would be if they developed ram air induction for the hawk?

What honda needs to do is develop the fuel injection for the bike finally! Move towards the light honda!

I removed the same piece and also the one on the right side (this one is crossed by throttle cables).
I think that without this two pieces the engine can breath cooler air only with a little bit more of noise.

Re: airbox, where does it breath ???

It makes sense breathing cooler air but why honda techs decided to not open these plastics ?
venturi effect ?
how do you remove the right piece ?

I think that those plastics are usefull to low down induction noise and to avoid that dirt can enter the airbox.

how do you remove the right piece ?
I don't remember exactly, but I think that it was as easy to remove as the left one.

Seems that some australian models has a different configuration.... no plastic plate under the snorkel ...

Could you please tell me your configuration with your Year/Country model ?

Re: airbox, where does it breath ???

have got an email from a canadian guy... He removed the two pieces but he replaced them because the performance was worse.
He tells me that these plastics are 'Heat Guard' that prevents to suck warm air !
Which is just the opposite we thought before ....

It seems very very strange!!!! Quite impossible!!!
I can't see any way from wich hot air can enter the way opened by absent plastics. Probably a little bit of warm air could be sucked at very low speed or at stationary bike, but in motion I think it's impossible.
My VTR runs fine without those plastics.

Re: airbox, where does it breath ???

Maybe it helps not to suck warm air at idle or low speeds (engine stalls ?)
Note that Honda part's name is "Heat guard" ....

I haven't noticed any worsening in engine stalls after the removal of the plastics.

Well....let's draw a curtain over Honda's translations!! ;-)
