I read on a web site (don't recall where) that you vcan get a good idea of your jetting by looking at your diffuser disks in your silencer (if you have them)....the article said that if the disks were black or pretty carbony, you were on the rich side----if they were a brownish/tannish/goldish, you were good to go---if they were clean or didn't show much of anything then you were on the rich side........same principles as reading plugs.

I've looked at my plug which is black and my disks are black-----it's a heckuva lot easier for me to look at my disks than my plug (thanks to the design engineers at Polaris [img]i/expressions/face-icon-small-sad.gif[/img] ).

I know it's not as reliable as reading your plug but it should give you a good general idea of what the plug looks like right?

Anyone else heard of doing this?

 

You could use this method for long term A/F ratio....but short term such as adding a pipe and checking jetting it's best too go by the plug. By the time the disks change color one could have a melt down...[img]i/expressions/face-icon-small-sad.gif[/img].

 

Good point!! So is there any use in knowing the long term A/F ratio? Maybe future planning of jetting changes to go with seasonal weather changes? Or future jetting changes with additional mods?
