  • Pms screw

    I’ve recently installed a alley cat air cleaner on my 03 1600. Ais removed. V&H 2 to 1. I’m running rich. My pms is 2.5 turns out with 167.5 main and 37.5 pilot jet. To lean out a bit would I turn the pms out or in?
    thanks

      Hey Lug, I have a small amount of blue smoke at a cold start, and soot at the exhaust end. I was running very lean before i rejeted and I may be spot on now but if I knew which adjustment to make with the pms I may be able to fine tune it.

    Check your plugs before assuming.

      Blue smoke at start up means oil. Its possible you've got oil pooling in the cylinder after you shut down. Could be valve guides, though I haven't heard of anyone having that problem on a R*, but there's always a first. It's not serious as long as you keep an eye on your oil level.

      As for PMS, turning right/clockwise is leaner, opposite is richer. 2.5 turns out is a standard "best guess" for most situations but ideally you want to "tune" it by dialing in (clockwise) when the bike is HOT, until the idle drops or stumbles, then stop and turn it back out (counterclockwise) about a quarter turn. I currently have mine set to 2.25 turns, which is ideal for my set up.

      Did you change your own oil last? Have you put any oil in since 4 quarts were added? Is your air intake filter oily?

        Hey Shores, yes I changed the oil 3 weeks ago, no change in level. I have the alley cat from SSCC. I rerouted the crankcase breather to its own filter and it’s still clean
