So i know it's just a stunt bike but one of the techs at my work said that the air box mod that i (we) have is bad for the motorcycle and could damage the engine. By putting a t valve in between the pair (pure ram air induction) valves and connecting it to the rear crankcase vent we are causing oil to dump into the exhaust ports eventually flowing into the header. Thats why when its on the 12 bar too long it smokes so much. Eventually it will damage the valves so he says. Any thoughts? Any alternatives? true or false?

look how many people have doe this mod. How many have had messed up valves. not me so thats one.

never had a problem with my pair mod.......

old man roger

he is an idiot because the alternative is dumping it into the combustion chamber and that can destroy the whole motor in a single shot, oil doesn't compress and when the motor tries to compress it the connecting rod bends or breaks and shoots out the front of the motor...

and how exactly is oil in the header gonna damage valves ???

I don't think it could but what about thru the exhaust ports? I dunno i'm not a tech guy so......

Theres threads all over this site that tell you how to do the air box mod

jstuntlocke

I don't know... maybe some of you guys have thought of this, or maybe it's ben mentioned before..... (I'm not worried about it) but it seems to me that the only other option is to put a filter on the end and cap it off like old trails guys do to their dirtbikes so the oil just goes there instead??

MY KTM had one on it when I got it for the exact same reason we do it to our bikes, except the guy said it's for if he was out on the trails and his bike tipped over, or got stuck upside down, he'd be able to still ride... but it dripped out of the filter eventually onto where??? ....the exhaust midpipe...hahaha so it just smoked from the outside instead!

Thats exactly how I use to have mine, the crank case breathers just going into small filters

BUUT someone on here told me you GAIN torque from having the clean air mod, like it SUCKS the crankcase gases out increasing low end torque or something like that

old man roger

welcome to the site and like brent said there are a ton of threads that tell you exactly how to do the mod and why , there are also pics to make it easy ...

use the search funtion and try ''clean air mod'' and then ''kleen air mod ''and then ''air box mod'' ,those three searches should give you enough results to make you an expert on the subject

old man roger

this is true , the mod creates a vacuum in the cranck case

sdfkillz

no problems on my bike 6 months in.

old man roger

had it done to mine for years

jstuntlocke

Like I said.....



.... I got the stuff to do mine the same way ya'll did a week or so ago. just ben too lazy to do it! doesn't matter since I need a couple more parts to make this thing rideable anyways.

If the Search would work would be nice, but I tried all these words a couple times this week and nothing showed up.....not even "air mod"

old man roger

heres one where every one argued about the mod for days ...lol

it's long but if you read the whole thing you wil understand how it works
