Spark plug mileage, 09

what mileage are you getting out of your spark plugs?
are you using something other than the stock plug?

NGK plugs. I've replaced mine twice and have a little over 20K miles on the bike. Don't get the iridium. Just the nice cheapo NGK.

I went iridium once and was underwhelmed.

I changed out the OEM plug at around 15K miles, still looked good. I replaced it with a regular NGK. Changed that one out at about 35K, still looked good.

Spark plugs last a long time these days. If there's no visable electrode wear it's good to go.

I agree with Spec, the KLR is easy on plugs. My previous bike (a non-KLR so I won't quote a miles-per-plug number to confuse the issue) did seem to need a plug much more frequently. On my KLR, I tend to replace them about every 16-20 K and they always look good and the bike was still running just fine.

still on original piston, rings, entire top end. Just an Eagle doohickey, torsion spring and a Thermo-Bob, of course!
Ride it like you own it!

I've been replacing mine at 10K, and it's only because I have the tank off and am doing a full service to the bike anyway.. Truthfully, the plug at 10K looks darned close to new..

I agree........just did mine at 10K since I was doing the 22 cent mod. Plug looked good and ran the same after the change. Used an OEM NGK.

I just put a E3 "E3.36 plug number" in my bike. I have done a bit of reading on it so decided to give it ago. I will let you know how it works out if the snow ever stops. It's April 27th and we are getting a huge snow storm right now... Grrr. But otherwise I was just running the good old NGK plugs and they were great.
