I took my spark plugs out to check them today and they looked good mechanically, but were covered in a fine red dusting. Iv'e never seen this before, and it's not on any spark color chart I can find. Anybody heard or seen of this?

Might be rust in the tank ,pop the cap see if you got rust in the gas tank.also could be any thing that can contaminate the fuel i.e fuel additive or such doe sthe bike run good

That's usually from some kind of fuel additive or octane booster additive.

Sta-bil is orange....

It has sea foam in the gas right now. Starts good, except when hot. It has to cool completely first. There is some spotty rust in the tank.

I had a very nice shade of purple when I used an additive alleged to make older engines live with unleaded fuel in my '56 Chevy. So I bet its in your fuel.

Were you pulling the plugs to try to diagnose a problem? How's your bike running? I've used seafoam for years and never had a color to my plugs except for the normal light browning. Tell us more...

Maybe you guys are using the same brand of gas?

Iv'e been having hot start problems. I use exxon 87 gas. I'm just using regular autolights for the plugs. The engine does have a hickup till it's warmed up. I was told to adjust the pick-up coils, so I did that. It was alot easier than I thought it would be. But I couldn't tell a difference. Maybe my ignition coils are bad. I can't afford new ones. And i keep getting burned on ebay. i got an R/R and it was bad. JC whitney had some they said would work, but I don't if they really would or not.

Hot starts can be a multitude of things. First of all, do you have a maintenance free battery? The wet cell batteries are known for eventually giving you many problems, the least of which is hot start problems. Your plugs are also suspect. I've heard some problems with those plugs in our bikes, but that's not always reliable info. If you want to do yourself some real good, get an MF AGM battery, and invest in a set of iridium NGK plugs. Your hot start problem should be gone.
You said you were buying an R/R. Why? Have you tested your charging system? Just curious.
