    Does anybody make a single cone air filter that doesn't make the 117 motor run lean .

    No matter what intake you switch to you may need to rejet or at least readjust carb settings.

    I no expert, but from what I have learned from John Sachs cone filters can reduce power. You end with with too much velocity through the throttle body. You might want to bore it out to slow down the air. Talk to Sachs. I have been told to stick with the stock air cleaner. I have a John Sachs bored out G Carb with Thunderjet and the difference over the E Carb is amazing. I also think it tunes easier allowing a smaller main jet, filling in the top end with the Thunderjet. For the price of a cone filter setup you can get Sachs to do your carb and unleash a lot of power and it just runs smoother through all RPM.

    Problem with that is I have a Triple XXX that is chrome, and after spending that kind of money on it I would kind of like to show it off.

    It would be nice to find a cone filter with a chrome cover over it so the filter does not see high speed air and pulls air from the back of the cone cover opening.

    Less vibration, more power? I may have to call John.

    We put the Mikuni and the cone air filter on, dynoed before and after and gained 10HP. The Mikuni woke the 107 up! E19635C4-B8E3-4243-BE36-6E1064F98B5A.png

    Vernon I don't have a problem with mine and I run it facing forward. I think I had to remove a bowl vent screw. It wanted to surge when I just cracked the throttle a little. It would almost throw you off the bike, real touchy. The idle circuit was rich and when the throttle was cracked it allowed the extra air to lean it and it would jump. I adjusted it out with the idle mixture screw. Go for it.

    I use a D&M cone spike. I did not feel any seat of pants loss of hp when I installed it 6 years ago. I think the problems with this type of air cleaner is the 90 Deg elbow. Any time air makes a turn it tend to compress or collect on the long turn radius or outside of the turn. It does not fully expand and fill the pipe until it has traveled about 5 or six pipe diameters past the turn. This all is relative to the airs velocity. This means that the air is not going through the carb evenly. More air velocity on the left if it is facing forward and more velocity on the bottom when they are installed facing up. I don't know how that affects a XXX carb. Maybe someone who has one installed on a XXX will chime in and maybe someone would offer to sell you one.

    I ran the single spike on my pitbull forward and now wimmer dual runner spike forward on my k9 forward with no issues as stated the bowl vent needs to be removed and simple tuning will be required no need to run it pointing straight up it looks better forward anyways

    I know this isn't a spike but maybe this is why S&S has the dual runner to obviously increase the air volume and it is a dyno proven power adder but not a huge gain.

    Same with wimmer Ryan designed all his intakes to increase performance and even supplies an extra kit for better tunining capabilities with the standard s&s carbs which was not required in my case as I have the xxx carb, check out his website or contact him wimmer.com great guy

    Maybe John Sachs could verify the difference in velocities in the long and short side turn radii in a cylinder head. My experience is more elated to 60,000 cfm and 600 fpm air flow measurements. I am assuming it is very similar on a smaller scale. I have never calculated the air velocity@ 15" vacuum.
