Iridium spark plugs?

[BajaRon]

I pulled the plug back out before i saw your post about the vaccum... the dirt was stuck in the thermal compound torward the bottom on the hole where the threads were i tried it wipe it out with a qtip which seemed to work alot of it came out... pretty sure nothing fell in, did the best i could. i did notice some dirt on the last thread by the plug tip so i was sure to wipe it off... it was very small deposits.

A little dirt sitting on top of the piston isn't the end of the world. It will get spit out the first time you fire it up. Shouldn't hurt a thing.

Not saying that you shouldn't try to keep dirt out but just saying I wouldn't worry about it.

thats what i read on the net.... these were like rocks or anything i made sure to blow it out very good with a can of compressed air as i didnt have an air compressor. my old plugs were straight black no white no gray just blackkkkk

0.76 mm .030 sae Just me but i have about 200 miles on them now, this Saturday I'll be going on a 180 mile trip, If there still running the way there running now they will be coming out and new stock ones going in.
It seems like i lost a little snap when i open it up. Slight hesitation on full throttle. Will know more in a few days.

Well i have 1250+ miles on the Iridium plugs, Still have a slight hesitation from a standing start, Replaced them today with new stock plugs. The hesitation is GONE. Guess they don't work for my Spyder.?:dontknow:
