    What spark plug are you guys running? I've been using a BR8ES in my WR250 ,stock plug is a B8EG.What plug will I get the best performance with?

    My previous bike (GasGas EC250) used the BR8EG as stock. The BR8EG is the fine electrode. The BR8ES is the standard (thicker) electrode. If you are jetted good, both worked fine on the GasGas and it sounds like the WR250 is similar.

    There is also a BR8EIX with iridium electrode. This gives a stronger, more concentrated spark. If your bike is jetted slightly rich, then the iridium plug can help some.

    On my Husky SM610, there was a steady throttle hesistation at 4000 rpm. The iridium plug on this bike made it work flawlessly with no hesistation. I guess what I'm saying is that there are better plugs out there if your bike is being finicky. If your WR250 runs fine on the BR8ES plugs, then I would just run them and save your $ for other goodies.

    I use the BR8IEX. I seem to have to change it a couple times a year or I get a miss at high rpm. I don't think the WR ignition is real powerful.

    If your bike is supposed to be running a resistor plug, run the BRES; if it's supposed to be running a non resistor plug run the B8EG. If you do a lot of trail riding at lower RPMs, some times those fine wire G and V designation plugs will foul easier than a regular thick wire S style plug.

    I run the BR8EIX iridium. I'm a big believer in them. What Matt R posted about them is correct.

    I still run the plug that was from the factory. Bought my bike in December before Christmas and hav ebeen iceracing mostly. I have the BR8EG. And the way my bike is jetted now the plug is dark grey and shiny and no spooge on it at all. Totally clean and looks perfect.:thumbsup:

    I buy mine in 4 packs on Ebay from a company called Pili-car

    Get your jetting cleaned up running a Champion N2C $2 at autozone then go to the Denso plug.
