Need a "lean" Map

Tank69 · 03-03-2004, 10:59 AM

By 954 is running rich and i'd like to try a "leaner" map if anyone has it. All I have is 2bros. Slip-on and PCIII, no other mods. I'd like to go the custom map route, but want to experiment a little more. I know it's NOT the perfect guage for fuel mixture, but my exhuast tip is very dark, only getting 110 - 120 miles before the light comes on and the guys following notice some unburned gas coming from my exhaust, which I noticed on my bud's 929 as well, so i'm guessing that this is common.

Umm, no!

Use the buttons ON the PC and lean out the range you think is rich, how much easier can it be?

I don't want to go adjusting buttons and end up hosing it up. Maybe I should have asked this question, can anyone share their maps with me so I can do a comparison and adjust from there?

I get about 90 miles before the light comes on.

What does, "I know it's the perfect guage for fuel mixture" mean?

Thats about what I get when doing hard canyon riding or a trackday.

That was supposed to read "I know it's NOT the perfect guage for fuel mixture", I fixed it. All I meant was reading the tailpipe isn't a very accurate measurement tool for determining rich/lean conditions. Just going back to my two-stroke days.

O.K., I get it. Are you running the 2Bros. slip on map? If so, you can try the zero map that they have. Or you can ask someone on the site for a custom map for a stock bike. It might get a better response than saying you want a Lean or leaner map.

you won't hose anything up -- every map sets the lights at the center point to begin with. Lean it out to test -- if you don't like it, just put it back to the center.

Why waste your time and energy. If you're gonna get a custom map done eventually anyway, just get it done now and save the hassle. Then you KNOW it's right.

How's about someone posting how to adjust the whole map. I remember reading that there is a little trick to adjust the entire map up or down. Say, anyone want to make a guess as to how many click's (when I say click's I mean number values)would be about 10%?(thinking of making slightly richer/leaner maps for high elevation tracks?)

There is, you highlight the whole map and change it in one shot LOL

My guess would be 1 maybe 2 notches would be about 10%. Just add (or take) 1 or 2 notches to low med and high, and see how you go. (to sequence it, hold the 3 buttons down while turning on the ignition, release the buttons, and then press one , say "low" and tap it to add fuel, hold for 1 sec to lean it out) and repeat for the rest.
