[thomas111]

Right guys just took my airbox off and wtf was Honda thinking with the lump of plastic with a air filter stuck in it can you get a k&n for it

[lloydie]

Yes but standard is better unless you want to spend a few hundred on Dyno set up for 1-2 bhp

even the K&N and BMC filters don't use a bigger element than std, they still have a large plastic plate.

K&N has a reputation of being hard to jet for [as its so free flowing], and unless you have a good few engine mods, it wont bring you any performance benefit by its self.

BMC do a street filter which is half way between std and K&N, it works well but you need to import them

and like Lloyd says, the std filter works great with some jetting mods and race cans.

the bottle is a catch tank for the engine breather pipes at are fitted in each cam cover, many people have put filters on the breathers and removed the bottle to increase airbox volume

Thanks AMcQ listen does anyone no if I will have to jet the vtr when I put these art cans on it or should it be OK and any pics of the airbox mod were to get the air filters to remove the bottle

[lloydie]

Art cans , yes you will need to play with the jetting .
Pilots normally up to 48s .
But as always a Dyno run will show you what you need to change

Stick them on, it wont be that far out unless you go changing the air filter from standard. Jetting is not absolutely necessary and you may run a little lean, (noticeable by by popping on the overrun) but If you want perfection and max performance then carb tuning is the way to go. There's a good chance you already have 48 pilots, so shimming the needles (if standard) and a little tweak on the fuel mixture screw would most likely be all that is required.

That's the cheap option otherwise you can get ripped off and go and buy a jet kit like Dynojet or equivalent. The only benefit of an aftermarket jet kit is the adjustable needles, unless you want to go the full hog and get sucked into the whole Dynojet trip. It more important to have the carbs balanced/synced, especially after making any carb adjustments with jets/needles/mixture.

Thanks guys for advice well when I brought my bike back home from the shop with stock cans on it was doing a bit of popping I will just leave the stock air filter in and when I get round to taxing it next year I will get the art cans put on it as waiting on rob getting back to me with my high level pipes
