    To me that seems counter-intuitive - unless I'm mis-undersanding. You put on a K&N and since it's flow more air (and hence, more dirt/dust) you put on a pre-filter -do I have that right ?

    If so...that doesn't make a whole lot of sense old bean :D

    Except that if he was going to uni filter it anyways, the K&N kinda makes up for the added uni restriction.

    I guess HT has finally released the guards. Good to see. Any fitment issues?

    My point was that if the engine draws less than either is capable of flowing, then which one CAN flow the most is moot. If the possible CFM of the filter is less than that of the engine, the engine, not the filter, is the limiting factor.

    Figure 800cc x 5,000rpm (redline RPM/2 for a 4-stroke) = 4,000,000cc/m Convert that to CFM and you get 141.25cfm. According to K&N (the "more restrictive" of the two) their filter will flow 176cfm. The air filter is not the limiting factor. It is capable of flowing more air than the engine is capable of drawing at redline.

    If you judge filtration efficiency by airflow alone, then both are worse than stock and neither should be considered. There's a lot more to it.

    Wouldn't the exhaust efficiency need to be factored in somehow?

    Well, firstly you need to read my post properly. I put in a DNA filter.
    The reasoning is that the air filter is buried under the tank and takes an hour to get at. So I put a low maintenance filter in there and put the pre-filter to take out the worst of the dirt. I never said, wrote or quoted that it was for performance. For me it's purely for ease of maintenance.

    Not sure if they have or not. I was able to get a prototype from them. No real fitment issues. They are a little difficult to install. You need two people. But they are very stout!!!

    In a perfect world you could gain a little extra effective flow from head velocity and a little precompression, but that also assumes perfect exhaust scavenge. For the filter to become the limiting factor, you're talking 20% increase in efficiency from exhaust tuning. That would be pretty impressive.

    Cut out the CAT and put in on the dyno :wink:

    That will increase the exhaust flow but not necessarily increase the volumetric efficiency of the engine beyond what the engine could otherwise pump.

    Haha, I have BMW gear for my off road riding, triumph jacket for my street riding, and currently don't own either! I think I'll stick to generic brands from now on. Anyone have experience with Klim?

    Oh boy, did I start a discussion or what? Anyway, nobody seems to dislike the DNA, although some people seem to hate the K&N. Anybody have any experience with BMC?

    A friend of mine has a Klim jacket and pants. So far he really likes them, but then he should for CAN$2,000. He hasn't had them very long and I don't think he wore them in a rain storm yet.

    I've got a Klim f4 helmet and a Klim Traverse jacket & pants. Love 'em! Great fit, great attention to detail, and they look good, too. My only issue with the Traverse suit is that it doesn't come with armor, you'll need to buy and install it. The jacket and pants have "pockets" for armor built in, but the armor isn't included.

    Interesting. I guess you and AV_Mech are the only two with prototypes out there. I don't have my tiger yet, but that day is getting closer.:D Trying to decide on options as I learn here.

    I know it seems to be the current "in thing" but at £800 for the jacket and £600 for the pants? :eek1 That's Rukka territory. And for something that might get ripped to shreds on the massive brambles we get over here. Not for me. YMMV.

    I have a couple bits of Klim gear and it's good gear but that is just ridiculous prices for stuff that, well, ain't that ground-breaking (despite what the fanbois will say).

    Some of the best tuners have been able achieve volumetric efficiencies greater that 1 in a race bike, its not not easy to achieve and those motors wouldn't last very long in a street bike.
