Default Fouled and rusty spark plugs?

I was wondering if anyone could tell me what might have caused these spark plugs to end up looking like this? I just bought my hammer a month ago and just now put fresh plugs in it.

I was also wondering how long I should wait to pull out the new spark plugs and check them to see if there is any fouling?

When washing your bike, be certain to dry out the plug wells. I use a leaf blower. Appears as tho you are running rich and/or not using high enough revs for clean burning. Grab higher revs and don't lug.

I don't think they look all that bad.
The rust was probably caused by washing the bike just before parking it. I always take my bike out for a spin after I wash it to evaporate the water that sits in places like that.

Thanks Ricz and Rwilly,

I do feel like I don't rev my bike's engine high enough before shifting up sometimes.

I kind of thought the rust was from the previous owner letting water sit in there too long. I'm just hoping they didn't let the bike sit outside in the rain too many times!

You can not rev your engine too high (there are built in rev limiters) but you can rev it too low. Keeping revs UP gives you more speed control, you'll use the brakes less and you will have far more control in curves. Use that lever down by your left foot.

I discovered the same thing on the used Vegas that I bought earlier this year. The first time I washed it and then road it the spark plug holes dripped brown rust water all over the engine. I freaked because it was my first time riding the bike and I thought my engine was leaking something. Once I discovered the caused I used a wire brush to clean the rust off of the plugs and now I stuff some rags around the holes whenever I wash the bike.

+1 on that Ric!
