What size injectors?

I have an '06 Electraglide with an S&S 100 ci
kit installed- had headwork done- 590 lift cams-S&S headers with V&H 4.5 HO slip-ons. Just bought a Performance Machine fast air forward K&N to up grade from the stock air cleaner. Also picked up a HPI 51 mm throttle body. would like to change out the stock injectors.. any recommendations on what brand and size?

The stock injectors will support 120hp. I don’t think ya need any/much bigger ones...

I forget the size, but mine are stock, 103, cam heads etc. Around 115/120 I forget now.

Do check to make sure if you had the problematic 8* injectors from 2006 that they were changed to the updated 25* injectors though.

I'd throw a set of hpi (horsepower incorporated) injectors in. Call or email and they respond quickly with an answer to your question. They have a great website too.

^^^check this first. There was a Service Bulletin on the 8 degree injectors for '06 bikes. The 25* injectors are not that expensive if you shop. My '06 has the old injectors and getting ready to change them
