Has any body used or is using spark plug washers? Was wondering if they work or just a waste of money?
Also does anyone use the E3 plugs? And are they any good.
 

Im guessing your talking about indexing the plugs? No gain for these sleds, waste of time and money. Your best off just running the good ol BR9ES with proper gap.
 
That's what I thought it would be a waste of money and time. Seen them online and was just curious.
As for the E3 I think they are over priced. My older brother said they made a difference in his xcr 700 but I couldn't tell the difference.
Besides I can buy a box of ngk's for what i would pay for 2 E3 plugs
Thanks guys for the info on the plug indexing.
