Ive got an 09 900 custom, im looking at a set of v&h twin slash staggered chrome pipes for it and a k&n filter for it but I don't know what to do as far as a power pack. I saw 2 different models from Cobra and one from V&H and a local dealer said they use dyno jet. whats everybody running and how do they like it? I see a lot about the corba fi2000r and power pro... I think im leaning cobra way. thanks in advance for the help.

Guess it depends on what kind of performance you are going for. I have a 2011 classic with Cobra pipes and a K & N filter. Still get 45 - 50 mpg and have plenty of power. I had the valve check at 20K and all were still in spec. Bike is 18 months old with 29K miles and runs greeat.

I went with the cheaper cobra because I couldn't pass on the price. A budget tuner for a budget bike made the most sense for me. I saw one review where someone put the FI200r on his bike, took it to the dyno man, and it was so good they didn't even change the tune from stock. Cobra sets it before they send it to you setup for aftermarket intake and exhaust.

How do you go about dialing in the fi200r? ive seen some guy say they take and have it dnyo tuned but by the time you get done with that your gonna have the same, if not more $ than you would in a power pro right? i want it to run good, with the correct af ratio. would like to keep my milage as high as possible obivously. right now im getting between high 40s low 50s depending on how and where im riding with it stock other than drilled baffles.

I haven't actually got mine tuned on this bike yet. Its installed but the weather hasn't allowed much testing. You tune the cheaper unit like you tune a carb. It can be complicated if you let it, but any novice can tune this thing because cobra is there to help. Most likely you will not need any changes. It comes preset. I do know that cobra dyno's and extensively tests all the bikes it sells tuners for so when you get yours it is very close. The one person on this forum that I found that has an FI2000r and took their bike to the dyno, it was so spot on that no changes were made. Also if you youtube the cheaper unit, I found a video of a walkthrough where the technician mentioned the last 4 or 5 he installed were spot on and no changes were needed. This unit WILL tune your bike properly, and the extra couple times you may or may need to pop the seat off and tweak something to your liking is worth the $300 ish dollars you will save. I'll make sure and post up when I take mine out for its first spin. I have the Cobra CAI, Cobra FI2000r, and RoadRunner/Hard Krome 3" exhaust. Planning on starting with stock settings, and most likely will leave it there unless there are obvious issues.

I think the most important thing is to do things right. When you start making changes you cant expect to go half way and get good results. Don't just put a high flow filter on without exhaust and the other way around. Get a free flowing exhaust, high flow filter, and the FI2000r and you will be happy. Don't forget to do the Marble Mod. IMO that is required. If your not happy and cobra cant solve your problems, most guys say a few dyno runs are only 35 -40 dollars. I almost changed my mind and went with the more expensive unit, but from my experience I just don't think this bike needs it.

I got my exhaust for $375, tuner for $160, and I think the CAI was around $150. That's the big 3 on the cheap there and I got top end stuff that will run with anybody. If you have the money and are worried about the cheaper unit, peace of mind is nice to have. I always go top of the line, but in this case I just don't see the need.

Ahh so your in the same boat as me.right about now. I've gotta go plow snow before I can go to work in this lovely -30° wind chill! I found the instruction book online for it and looks pretty straight forward. I tuned my last bike, that had 4 carbs so I cant see this being harder! What is the marble mod?

Top right hand corner of the stock air box there is a 3/4 (might be a 1/2) hose. When you add an aftermarket exhaust without a CAT, you need to block that hose off with either a marble or I used a red wire nut. Throw a zip tie on it to choke it down on either side for piece of mind. Then you can reconnect it to the stock box or in my case with the Cobra intake they gave me a little billet filter screen to attach to the end.

What this hose does is feeds air back into the exhaust system. With a CAT you need that extra air to help the CAT burn up unspent exhaust gasses. Without a cat your not going to be burning that extra anyway so the extra air can only cause backfire. I've personally logged about 10k miles on my last bike with it blocked and no adverse effects and plenty of other folks have done this mod so its very safe. Let me know if you need a pic, but its the only hose on the top right connected to the back of the air box.

Ohhh Ok thanks for the info! Where is the cat hidden I was unaware it had one on it. Didn't notice any big spots in the pipes where it would...
