Tuning 2001 ultra

[SharpeFan84]

I have a 2001 ultra that is fuel injected. I put Big Louie slip ons on and now it is running lean. What is best option to fix it? Heard horror stories about M M injection but there has to be something I can do. Looking at Cobra Fi2000 hope that works.

Check your basics including intake seals. Adding just pipes shouldn't make the bike lean with a stock air filter and air cleaner canister.

Everything stock but slip ons. So I will check intake.

Looks like they don't go back as far as 2001.

I had problems with my 2000 ultra classic being very inconsistent when I first got it also. It had a 95" kit with se 203 cams and stock header, V&H mufflers , and a power commander. I spent hours at the local indie shop on the dyno and couldnt get it to quit being a tempramental b@#ch. I ended up getting a S&S VFI ecm and after installing it and finding the right map I was happy. I am still happy with the tunability of it and am still using it even after putting high comp pistons, ported heads, 2 into 1 header, and flora cams in it .
