Hi all! I have just picked up an 88 sportster 883 that was converted to a 1200. I checked the plugs and found it to be way lean. So I checked the jets and it had the original 883 jets in it.


the main jet is a 170 and the pilot is a 35. Curious to see what I should up the jetting to without buying 10 different jets

 

I would suggest the same jets that a 1200 shovel ran. Like 180 and 45.
Also I called 883-1200 and got a busy signal.

 

Everything you need to know about CV Carb jetting is here, enjoy the read and knowledge:

You will find a chart in this link that shows the stock carb & jetting for specific years of the Sportster 883 & 1200, probably should go with the stock configuration for a 1200 of your model year:

You bike is also running lean it your drag pipes so not have baffles.

 

The number has been changed to 867-5309....ask for Jenny.

 

thank you for those we ended dup going with a 190 and it is running perfect. At first it was a little shaky but cleared out and ran great
