View Full Version : Jet size help

03-14-2014, 6:08 PM
My 75 ironhead was having a problem idling so I pulled the bowl and cleaned it and now she's running great. Long story short I finally got a chance to check my jet sizes. Am I special needs or am I reading the wrong. Main is .064 and intermediate is .265. Does that sound right or do I have the decimal in the wrong spot. Bike runs great. Plugs look fine. 75 IH, some pipes that look like at some point it was a thunder header someone loped the part that it comes into one pipe. And oh yea it's a super e. Thanks

Sounds about right, intermed. Might be a bit small, but if it works for you, don't change

If the plugs look good your ready to fly.
