It's one of those E3 plugs - it was just the one that Amazon said was compatible and I could get same day.
As for the rest of the questions:
* It is a carb kit, but it's a good kit that ran me $45 just for a minimal number of parts and not one of those $10 kits that included everything. For example, the air/fuel mix screw looks exactly like the original, it wasn't one of those longer ones.
* It's got a Raptor petcock on it
* Washer is on the main jet like it should be
* I did go down a size on the main and pilot
* I did take out the air box and put in a K&N style filter and rejetted it one smaller than it already was - not sure if I have to go even smaller.
* There's no fuel in the oil from what I can see.
* It's pretty much been like this since I got it.
I bought this bike for $50 not running. Whatever fuel was left in the tank leaked out and around into the crankcase. The guy I got from said he had it running for a little bit but it was really rough. I wonder if he was running it with that fuel/oil mix in the crankcase and if he did did that screw something up.
I did a carb rebuild and yes, at first I used a cheap kit from amazon but then I redid it again using an All Balls kit 26-1705 see
