running lean

[Bucket]

i run mine on metho Bex, if i run out, distilled water.

its normal for the exhaust pipe to be black inside on unleaded
does anyone know if the exhaust can be read to show whether its running rich or lean?

BTW, on LRP the exhaust should be a dark mottled grey

Go down to a dyno shop. they stick a sensor up the pipe and test it at different rev ranges. its how i found out mine is running lean at full throttle.

lean as opposed to other normal VL's they have run on the Dyno stock or... If they told you it was running lean, did they have some explanation to back it up? Can you tell us what the reading was at all. I haven't Dyno'd my crapper so i dont know what it would be.

Was it constant every time they ran it, maybe injectors dont flow full range due to blockage... maybe fuel pump not working to best it can but was this an issue that made you take it to them, did you notice a lack of power at warp acceleration?

they said it MIGHT be the AFM. they didn't want to adjust the AFM as it would then run rich the rest of the rev range. the fuel flow is good. i wonder if its cos i took both mesh out of AFM? no idea!

Test your AFM

1. Grab a multimeter.
2. set it to ohms Ω
3. unplug the cable that goes to your AFM
4. hold the multimeter probes on pin 1 and 6 of AFM
5. turn the adjusting screw on your AFM until you get a reading of 382 ohm (this is factory default setting).
6. plug your AFM back in.
