"A spark plug for use with internal combustion engines includes a metallic shell housing having a semi-cylindrical shroud partially surrounding the insulator and the center electrode and to which the ground electrode is joined. The semi-cylindrical shroud promotes improved heat dissipation from the ground electrode to the shell housing."Sonreir said:Plug aren't there to remove heat from the chamber. You've got an aluminum head and plugs are steel. They will almost always be hotter than the rest of the chamber (except maybe the valves).
I like the NGKs because the side electrode doesn't protrude as much.
As far as platinum vs iridium, the main difference is that the iridium lasts longer. Similar performance.
If you can find a set with multiple side electrodes, go with that, though.

kinda like everybody calling a wheel a rim nowadays, we can thank the goddam lowriders for that
GET OFF MY LAWN !!!!!!!!!

a hex key makes so much more sense. What do you think about Denso's claim to their newest iridium plug? Did the bikes they built it for the xr250 and cb400 have heat related issues?teazer said:Rockers vary quite a bit in weight, so I sort through them all and select the lightest and then start lightening them some more.
Those adjusting screws are even lighter after they are drilled and broached to take a hex key (Allen wrench) and there are Ti or Al nuts but watch that they don't come lose. A touch of blue Loctite is needed with Al nuts.
Use Iridium plugs if you can get them in the size you need and start one grade cooler than you think you'll need and then start reading the center electrode and side strap (electrode) for signs of heat.
FYI different fuels burn differently and you need a hotter plug (lower number in NGK series) to burn off the carbon with unleaded fuel. With race gas we use D10 and with street unleaded we use D8s. Check plug length and index the plugs and check for plug to piston clearance. We have to fire notch our pistons to clear the plug.
