    I've read the reviews of the maxair system off of their website. I thought i would try to get an honest opinion from some of you who may have this air system installed. Here's my set-up. 2008 vstar 1100 silverado, cobra pipes,
    (shorts) and rejetted for the pipes. I seem to have a small flat spot in the throttle sometimes after it's warmed up. Weird, but it's not always there. I want to purchase the maxair kit and install myself. Is the performance difference that noticable? Is installation a problem? (i'm pretty good with a wrench) my mpg is not that good now.....around 38-43, depending on how i drive. i read that the mpg will improve.
    Love my ride.......just want to do all i can to improve the overall performance.
    thanks in advance for any help.....

    This spring, I removed the AIS, plugged the ports, installed the Maxair kit and installed Cobra HP-Pro exhaust on what was my stock '05 1100 Classic. I don't have a dyno run to prove the difference in performance, but it's obvious to me that the bike is way, WAY quicker, and it doesn't seem like the bike needs a 6th gear any more. Sounds really nice, too.

    My gas mileage went up about 5 mpg, from 40 to 45. I have seen reports of better gas mileage for the 1100, so it must be that I hit the throttle hard.

    I don't know if you would notice such an increase in power or gas mileage, as your bike has already been rejetted and a more fee-flowing exhaust has been installed. I'd assume something has been done to the intake as well to make it flow better? If not, then you'll definitely see improvement with the Maxair setup with the 2 K&N air filters.

    As for installation, I did all of the above myself, including adjustment of the idle mix and synchronizing the carbs. Maxair provides good step-by-step instructions, all the jets you'd need for any exhaust setup (and direction on which jets to put in depending on your exhaust) and the on-line support is truly excellent. If you are handy with a wrench, it'll be a piece of cake.

    IMO, the Maxair setup rocks. If I had another 1100, I'd install a Maxair in that one too.

    You will not be disappointed in your decision about the maxxair kit. It is awesome.

    Would it do any good to install the Maxair if I was not planning on changing my exhaust anytime soon?

    If you have a stock exhaust, then probably not. Even if it did some good, you'd have to do it all over again with different jets to match your exhaust setup when you change that. I'd wait and do it all at the same time.

    I am waiting on my MaxAir kit to arrive (as well as my Cobra HP 2-1 pipe), but I am definitely very excited (and a little worried) about this project.

    G, since you are running essentially the exact same setup I am going to do (and because you seem so happy with the result), would you mind posting which jets you used and how many turns on the pilot mixture screw you used? I already have the AIS removal plugs (the "gauranteed no chirp" ones from e-bay) and I plan to install those when I have the pipes off. I've read elsewhere that some people do not like the MaxAir - saying their needles are way too rich, the float level should NOT be changed, the setup is very difficult to tune and that it is way too expensive. That they're poo-pooing on MaxAir so much seems makes me think that there is either some agenda at play or they did something wrong in their installation. I have no proof of either, but it just seems odd to me that so many others absolutely love the MaxAir system.

    I spoke to a guy who, I believe, is perhaps the owner of MaxAir. He was very helpful and direct and I felt like I could call him again if I ran into trouble. I really just want this to be right, which is why I didn't just buy the pod air filters, jets and such and just work it out myself - too much trial and error. I figure that the MaxAir (and other) kits are specifically designed for this bike and the kinks are already worked out. That makes it worth the price if the R&D is solid and reliable.

    I have heard the poo-pooing of Max-Air also, but I did the install last winter with gutted stock exhaust. Couldn't be happier with it. The response is alot better, mileage improved from 40 to 45 average. The only issue I have with it is that you can hear the bike sucking in the air when I goose it. (Maybe my install).

    If you want to see the instructions, PM me and I'll email them to you.

    Hey,

    To answer your questions above, I used the main jets that Maxair recommended for my exhaust setup and the year of my bike - 145 front, 142.5 rear. The PMS is set +- 3 turns out - I tuned them after the install (new Maxmix screws). Your bike may (and probably will) differ.

    You probably spoke to Lee on the phone. The online support at Maxair is great; you will get the help you need there if you run into trouble, and you can also call and receive assistance. Just follow the instructions to the letter and don't overthink it. Synch your carbs when you're done. I did not find this setup difficult to tune.

    You can find raves and rants on the 'net about all of your options for performance mods on this bike. All I can say is that my bike performs like a champ. Seems clear to me that Maxair's R&D is solid and reliable.

    Thanks for the reply. I spoke to Lee again today and he assured me that I would have no problem as long as I follow the instructions to the letter (which I certainly will do). I think I made the right choice going with that system. Far too many people fail to recognize and appreciate the R&D that goes into a product like this. I've read all the comments about how the parts they use are not that expensive and that one can save a ton of money just buying this stuff piecemeal. The thing is, I am not a carb expert. If I did something like that, I'd have nowhere to turn if it didn't work. Having the support network behind me IS worth something and Maxair seems to have that all sorted out. So, yeah, it might cost a lot of money but so far it is WELL worth it.

    I started this project late this afternoon - beginning with the OEM exhaust removal and the oil filter relocation kit. What a pain in tha backside that was (the ORK). Why can't these companies make those silly braided oil hoses with the fancy clamps already on them? I spent at least an hour (and half-pint of blood) trying to get those stupid clamps over the raw edge of the braided part. What's more, I am not confident that they will even seal properly. Since I have the pipes off, I didn't start the motor yet so I'll have to wait until tomorrow to see if she leaks. If it does, I think I'm going to take the stupid thing off. My Cobra pipe doesn't look like it will block the OEM oil filter housing like the OEM pipe did.

    That Cobra pipe WILL block the OEM filter housing...

    Dang it! Oh well. I guess I'll have to make sure the ORK lines don't leak then. Wish me luck. The sun is up here and I am about to begin my foray into much better motorcycling!

    Just some general information;

    If you have trouble, for custom hoses go to a hydraulic shop. they have a much better array of hoses and fittings and everything, and they can put it together for you.

    I say it is "nearly" complete because I just have to balance the carbs (which I am going to do this week). I got the bike back together last evening and took it for a test ride. Good golly miss Molly -this bike has been transformed!

    The increase in torque is fantastic - I rode some of the twisties I am used to and found that I no longer have to down-shift for a clean corner exit. The bike also feels like it would pull hard to at least 105 now (of course I didn't try it) - before Maxair, it felt like it was screaming at 70. These bikes must really be plugged up from the factory because I can just tell that it is breathing much better now.

    The Cobra HP Pro 2-into-1 pipe is a bit of an odd-looking piece (on the V-Star at least) but the sound it makes is totally intoxicating. It is not extremely loud, but it will bark when you jump on the throttle. Add to that, the resonant rumble at cruise speed and it sounds more like a mid-sixties pony car than a V-Twin cruiser. Drop-throttle sounds are amazing, too. There is no popping, backfiring and the cruise decibel level is just enough to mask the whiny drivetrain.

    I can't say enough good about the Maxair product. They include everything you will need to complete the installation, the instructions are very clear and it only took me about 3 hours from the time I took the tank off until I hit the starter button. In the unlikely event that you run into trouble, there is an absolute wealth of information on their private technical support webpage (you must be a customer to log in) and you CAN call them if you have to (though they don't come right out and invite you to do so). I am by no means a carburetor expert and I've only worked on my own motorcycles for about a year. You can't get much more novice than me when it comes to this stuff. I was VERY nervous and perhaps downright scared to tear my brand-new bike down. My wife looked on with doubt and disgust as I removed the tank, air box and carbs. She doesn't see the point of mechanical modifications, I suppose. Anyway, I followed the Maxair instruction sheet to the letter, and it seems that it was a fantastic success.

    The best part is, the ORK hoses don't leak!!!
