Upgrades

[mo1200]

I was thinking of installing the SE Stage 1 Air and SE performance Slip on muffs on my new 1200C Sportster. Now I got to tell you I like the sound of it now and it runs great. My question is, am I going to notice enough performance boost to make the expense worth it? I only ride 2 up from time to time, most of the time it's just me and my little rocket. Do I really need more HPs and Torque? It will already go faster than I'm brave enough to try. Any advise would be greatly appreciated.

The benefit of Stage I is between 10 to 15 HP...which amounts to 15% Horsepower and torque increase whether on the dyno or "seat of the pants" measurement to be sure if all three items are done. You have stated two of them, SE Stage 1 Air Intake, SE Performance Slip-Ons Exhausts, but this will run your bike dangerously lean unless you should add some type of EFI Fuel Air/Fuel Ratio Upgrade Device such as TFI to complete the upgrade:

When you do your upgrade, save all your HD OEM parts, as government and local ordinances are starting to clamp down on modifications that richen EPA mandated regulations (SMOG) or modifications to the exhaust system (NOISE). If you have the dealer do it, make sure you get them back they are your parts! JMHO

You wanna pay the "Harley Tax". Best bang for the buck performance upgrade. Used to be a freeflow breather and pipes and a couple of jets. Now the jets are replaced with fuel management.
Here's a list of them to compare different ones(thanks glider) the TFI is quite popular

I don't know much about the 1200s ,but with my 96ci the stage1,TFI and slip ons brought it to life and cooled it down.I wish it was the first thing I had done when I bought it,not waited a year to do it.

They just run so much better with the stage 1 and some slipons with added fuel.

Ok, thanks everybody. I have read about about a fed crack down on noise and pollution. Anybody have an idea what the TFI a/f device cost along what my dealer may charge me to do the work? It's starting to sound more expensive than I thought. Does the old saying apply here? Why fix it if it aint broke? That money would go along way toward a set of bags, windshield engine guard etc.

The TFI will run about $250 and you can actually do it yourself. It's not difficult at all.

There's videos and other posts on the TFI here.
