i just got to ride my Raptor for a full day after putting on my HMF and Dobeck.
The next day it wouldn't start and I noticed that the plug was fouled. It had a black tip.
Am I running to rich or lean. I'm running 4,7,8,7 on the Dobeck, should I change my settings?

You must be running fat, Try leaning it out

 

[Alex700R]

Which pot should i change on the Dobeck?

 

[sikraptor700]

Where was most of your riding, lower rpms crusing or lots of high throttle???

try 3:30, 6,7,7

you can also try what dobeck rec. 4,7,4,9 , I have had no issues with my settings so far on my bike and I do allot of slow trail riding and have also done some draging at the dunes

I do alot of trail riding...Mostly slow paced, but I do ride hard alot.

Also be sure to let yoy Raptor warm up a couple minutes before you ride. Don't touch the throttle till it's warmed up.

The iridium plugs seem to be a lot more foul resistant too. I 'just' changed my NGK Iridium that I installed in January. The plug coming out was fine, I just wanted everything tip-top for the dunes.
