jetting

Your best bet is to put a fresh set of spark plugs in (remember to gap them correctly) and ride the bike for a hundred miles or so.  Pull the plugs out and see what they look like.  Or you could take pictures and post them on here.  Make sure you tell us which plug was from the front and which one was from the back.  Does your bike run badly? Why are you concerned with jetting?

your jetting from the factory if it has not been changed should be 42 slow and about 170 main i would put in a 45  slow if you know how  that would ricten it up a bit i run a 45 slow and a 190 main  but its a little beefed up a bit  your plugs should be a tanish brown  not white  white would mean your a little lean    im trying to think of a good colar to compare mabee like a chest nut brown   they come realy lean from the factory to make the epa happy most change the jets  the 45 and 170 is a good starting point for you good luck ride safe sporty481

Hello!
I have 45/180 on my converted 883-1200 with Andrews V2 cams. The stock jetting is usually lean, particularly if the bike has a hi flo air cleaner and pipes fitted. If you go to the sportster web site - www.sportster.org - they have a good tech section which discusses jetting, how to do it and what sort of sizes you might need.
If you want to check you plugs, do replace with new, but to get a decent reading you need to run the bike hard - wind it right out in third or fourth on a long straight and then kill the engine at max revs and coast in. This will give you a good reading for the main jet from plug colour. If it is running rich you can usually feel the engine balk and stumble when you roll on the throttle fast and hard - the cylinder gets flooded. running lean is much worse for the engine - you can sometimes hear 'pinging' and backfires on over-run.
cheers

Las Vegas is 1800 ft. above sea level. What is the altitude where you live?
