Im going to buy the vance and hines short shots and a roland sands air cleaner and was wondering if anyone knows what i should be using for jets??

 

Use a 45 or 48 idle jet, stick a spacer under the slide needle (not just any lump of iron but a proper one, most Indies have them left over from Dyno Jet kits) and go to a 190 main for starters. See how it perfoms and look at the plugs, they should run grey with a darker ring around the edge of the plug at the end of the threads.

I run 48 and 195 but Kiwi gas is different to yours.

 

I have a dynojet kit installed, and using a 46 pilot jet and a 185 main, with fuel air screw turned out 3 full turns, bike runs like a champ, installed is an S&S air cleaner with Vance & Hines big shots, no other mods to the motor.

 

Just re-read an article in American Iron (May 2011) on this very subject. The author, Joe Minton, suggest staying as close to the standard slow jet if you can, a #45. If you must go up go to a #46. Not available at HD. The main jet is fine. The idle mix screw is turned out from lightly seated to 2 turns as a start. The needle is changed out to a HD part number 27094-88 ('88 Sportster). He used to recommend using two #4 washers to raise the needle but has since shyed aware from the shims in favor of the Sportster needle. This is a good article if you can find the magazine somewhere.

 

I like 48 and 190
