Case in point.
When I had my YZ250, I went out and bought those 10+ dollar iridium plugs. Every fricken time that I ran that bike for more than 5 or ten minutes at half or quarter throttle, (due to trail conditions), the damn things would foul up.
Went to Kmart, got a 99 cent copper tip Champion plug and ran that SOB for over a year with no fouling issues whatsoever. That bike started on the first or second kick every time and I had no performance problems whatsoever. |
Good ol' Champion plugs!! I'm not surprised they lasted so long and performed so well. Sometimes I think the new plugs are overengineered and overhyped. You've got the Splitfire, the Platinum and the Iridium, etc. Just keep it simple. Heres the NGK's my bike uses:

Theyre not platinum or iridium...just the standard model with two posts instead of the traditional single. Problem is...I cant find the gap tool online that would be used to evenly bend both posts for accurate gapping. Or is it done another way? Anybody use this type and gap them?
