    I'd like to hear from anyone else out there with this combination on their 1100.

    Last month, with some help from a buddy I replaced my stock exhaust with the Hard Krome 2.75 Big Straights, and installed the Maxair Predator Pro air kit, with the Max CSR kit.

    All I can say is WOW....

    It feels like I have different bike! Well...the same bike only BETTER. Obviously the sound is awesome, and I expected that. But really didn't expect the increased throttle response, and power increase.

    Here's what I'm wondering...am I just geekin out over my new mods? Is there anyone else here with this (or similar) setup that's perceived big performance gains?

    I put the predator pro on my bike about a month after I bought it - with a Cobra exhaust. To be honest, I was a little disappointed with the power of my V-Star when it was right out of the box. The stock intake is just too restrictive and I suspect the OEM exhaust isn't the best breather, either. Anyway, I was stunned with the improvment after the mods were done. My buddy rode my bike before and after the change and he also commented that he thought I'd picked up 30% more power. I am not sure how much power I actually gained, but the thing never pulled on my arms when it was stock.

    I did a lot of reading before I bought my predator kit and I still believe it is the best one out there - at least in the world of turn-key solutions. Being that it is a pod-style modification, I would expect similar results with the other piecemeal solutions (for less money) but I couldn't be happier with my choice. Their tech support and customer service is second-to-none. I know of at least two other people here who have predators on their 1100s and, to my knowledge, they are also extremely happy.

    Be safe out there, and enjoy your new bike

    I am still very happy with mine. Cobra Speedster Slashdowns and Maxair Pred. Pro, I love the sound and like everyone else I couldn't believe the difference after the install.

    I still remember the night that I test rode it after the install. Just after dark and a cold front had just come in and getting really cold but I couldn't stand to wait. I took it out and it was unreal the difference! Even though the wind was blowing me around pretty good and I was really cold I just couldn't get off of it. Anyway I made it back to the house and practically forced my wife to get on and take a little ride with me. She, like myself could not believe it. I was so pumped up I could hardly sleep that night! I still love it!

    That intake mod is the biggest bang for the buck that you can get out of an 1100. Whether it's a store bought version or DIY version, done correctly it's well worth the effort. With aftermarket exhaust added you'll get an easy 6-8 HP.....

    One thing that is nice is that there is a TON of setup information available no matter which way you go....

    I completed my Maxair install w/CRS about a week ago. Yes it is worth the $$ for the power you get in return. I also removed the AIS and installed a set of HK's Road Burner Double Eagles. Great sound! I am wondering just how much my mpg will be after the mods??? I used to get 44 on almost every tank.

    It'll probably drop a bit....which is usual, but hard to say how much if if it does. What jets did you put in? Where did you set your PMS?

    I just did mine with a pair of K&N RU-600 filters with pilots/main jets and bowl screws from Tim B for about $100. Went to 157.5 mains, 22.5 pilots, but I may drop the jet size to 152.5. Mine is an 06 (pollution bike) so I also drilled out the solenoid holes and ground down the jet holders. We'll see how it goes.

    I see you are from Missoula! I spent a lot of time there. Great place for riding. Have some good friends there, in Kalispell and in Helena. I really miss the fishing.... but not the winters....

    I put the Maxxair Predator Pro kit on this spring as well, and could not believe the difference. I couldn't believe I was on the same bike. Nothing but smiles. Well worth the money!

    I used 22.5 pilot, 142.5 and 145 for the mains. the pms are at 3.5 I have only been able to ride 1 day last week due to cold weather - 25degrees when I leave for work in the mornings and 50's when I ride home from work.... maybe I will have better weather this next week? I will be riding more when morning temps get in the 30's and 40's.

    Kind of an interesting set up. Stock pipes?

    I have the HK Road Burner Double Eagles and they are rather quiet until you get on it - then the pipes let out that great sound. Basicly they are like open pipes with glass packs as 2" diameter mufflers. Really a nice set of pipes.

    Those main jets just seem a little small. Most guys running similar set ups are in the 150 range for mains plus add a shim to their stock needles. I'm just curious about the mid and top range performance. You are around 4,000' above sea level?

    The Predator kit comes with the Maxair needles, though, and I think those run a fair amout richer than the stock ones. I think the main jet sizes he is using are correct for the Maxair kit and that exhaust.

    Most of the riding season, I run my PM Screws (the Maxair ones) at about 2.75 turns. I usually back them out to about 3.25 turns when the cold weather gets here so it doesn"t take forever to warm up.

    Thanks man, I forgot about having to change the needles too. I was wondering why the mains were so small. Especially at the higher altitudes.
