Review of my Hobbit's plug chop

Jessie Paull /

Just did my first plug chop and I'm a little confused by the results - I'm seeing a chocolate color but only on half (see pictures); the other half was completely white. Is that normal?

I got the bike warmed up, swapped plugs, the rode just about a mile WOT before I cut the engine.

I like my plugs a little more cooked than that. Looks like it could be on the lean side. I always like to be rich and mabye four stroke a little on the top end. Makes me feel safe.

Last thing I want to is to seize, so maybe I'll try an upjet just to see how it goes. Man are hobbit carbs such a pain to get at though..

Is it normal for only half the plug to color, though?

That's not technically a plug chop. You're supposed to cut the threads off and look at the base of the ceramic. Just saying.

I'm no expert, but lack of color on a side seems like uneven combustion. I dunno.

Usually a super lean side like that can be an indication of air leaks. That side of the cyl is getting a leaner burn. Before you rejet, take a moment t to text for air leaks. Could just be your head nuts are loose and need re-torqued.

That makes sense - thanks for the input I'll definitely check into that

I know technically we need to look way down in the plug or cut the plug in half and analyze it with a spectrum analyzer but usually we just rip the shit out of it and hit the kill switch and hope the plug isn't white. I am of the school where I jet so high the bike is so rich it wont move and soaks the plug. I would rather soak plugs with fuel than burn up my kit yo!!

Wiki says otherwise? Maybe I'm missing something.
