What spark plug works best in the KLR? Stock, or some super plug like a platinum, or iridium. Why would one be better than the other, and is it good enough to justify the extra cost? Rick A17 [Non-text portions of this message have been removed]

Thanks. Any specific brand / number? Rick A17

I have seen the stock plud show significant wear at 5,000 miles.. If you are a Mudder you might consider the Champion plug with a 16mm body.

My original plug, the standard NGK, came out at about 35,000 miles. The gap had opened up quite a bit, but it was still sparking happily away. I have heard mechanics grumbling about platinum and iridium in BMW cars, and can't think of a good reason to spend the extra money, even if it is only once every three or four years.

Well, we have one vote for the iridium plug, and one for stock. Where do we go from here? Rick A17

If you were looking for more responses, then you should have asked which is the best oil to use in your bike.... I've had iridium recommended to me, but I've never tried anything other than stock plugs on all my vehicles including my KLR. I've never had a problem, but then again I'm fairly diligent with all my maintenance. I guess it also depends on what you mean as "best" for the KLR. Performance, reliability, MPG, all of the above? Since I've only used stock, I can't tell you what I'm missing with using a iridium, split-fire, or other improved plugs. As far as brands go, I stick with Bosch or NGK. I don't mean to slight other brands, it's just that I've never had a problem with those two brands and so never saw a reason to switch.

I think you may be giving the plug more thought than it deserves. My motto buy two or three plugs at a time and always have a spare handy. With plugs in the KLR. It's more about convenience. You won't gain any horsepower with one plug versus another. How often do I plan to check/change the plug? Frequently? Buy the stock NGK. Less frequently? Buy the iridium NGK. The standard NGK works well and is cheap. Around $1.49? last I bought a few. The iridium NGK if you plan longer trips or less frequent maintenance. I forget what the iridium plugs cost and didn't note the cost in the maintenance spreadsheet. So it must not have been over $5. I bought two or three of each plug several years and several decent size trips ago.. I carry spares on the bike and keep a couple in the garage. Cheap insurance and minimized hunting of parts for less than $10. Check O'Reileys, Autozone, PepBoys or equivalent. If they don't stock the plugs they can get them in less than 24 hours. Usually at a significant discount to the Kawi shop. The plugs in a good KLR engine seem to last forever. Jim What's left of an A7 after improvements

I just threw a generic question out there to see if there was any advantage to using a different plug than the stock one. You never know what you might learn. I also keep my bike maintained, so it appears that there is no advantage to an expensive plug, other than life of the plug. Might as well use stock, and put a fresh one in every couple years.

That seems to be the consensous. If i had a ZX14 i might want to spend more on a plug, but in the KLR, I will just put a stock plug, and let er eat. Rick A17

Seal the hole against compression leak 2. Conduct electricity 3. Dissipate heat That's about it. Manufactures came up with iridium, multiple electrodes, fancy names and any number of things to "market" they're products. Some late model cars do use the spark plug a little differently but that's another story. In those cases the harder compound electrode do help prevent wear facilitate good current flow. As for our KLR's - Use the OEM or brand X equivalent but be sure to try and get the heat range right when crossing over. No two manufactures have identical heat ranges and will most often direct to a colder plug vs. hotter for obvious reasons. IMO spending more money for a better mouse trap is worthless. Now if you're talking 2 strokes..................never mind. That's my own personal problem. [Non-text portions of this message have been removed]
