Idle drop vs colortune

Post by Wreckster »



My bike already runs very well, though I never set the pilot screws individually. I can do the idle drop but using a colortune looks to be a much more accurate way of setting the mixture?

I use a Colortune on all of my bikes. It's a very useful tool and sets the idle mixture perfectly. If you have access to a very accurate tacho, the idle drop method is just as accurate, but, as I don't have access to one, my PERSONAL preference is Colortune.

Got the colortune and set all cylinders as best I could. Bike runs smooth, but it was pretty smooth to begin with. I think one was a touch rich, others started off blue.

I dont think I got it right as it seems to run a good deal hotter now, too lean I'd suppose that means. I'll have to go at it again and see if I can get closer to that just off rich mixture (just before orange flame). Might be it was running cold before, but gets up near fan temp quick for what's a cooler night.

Need to note. It's a heck of a lot harder to actually see the color changes than I thought it'd be. Really cant see the blue go white, more that it just starts misfiring. It's also a bit hard to really see if the flame is going orange as it's a messy burn. Might be blue with a hot orange spot for example or alternate orange blue.
