06 rm125 spark plug

[fwsteal]

Anyone know of a different spark plug for a 2006 rm125 instead of the plug that comes with the bike? The default plug seems to be a little expensive - got prices quotes for $40 and $28. A plug shouldn't cost that much.

06 is not even on NGK's site. :(

You can use a BR9EG, or a BR9EIX or other similar plugs, you do know there is a reason Suzuki and Kawasaki specs that expensive plug though right?

I called a local shop and they told me to use a BR9EVX; no, why the expensive plug? Is it because the 125 is being phased out?

Really it should not be an issue, if you have the bike jetted properly you should not need to change the plug with any regularity that effects the budget. My Son's 05 is still on the stock plug, his 03 went two seasons on the stocker as well. Cheap insurance at maybe $12 a season if you shop around.

thanks Chili; my plug fouled last Monday during practice and was a bear to get cleaned and started again.

I'd get some cheap plugs and get your jetting sorted out so you're not fouling plugs and then switch back to the stock plug.

You really need to get to know someone at the local shop and get a discount. I get many of my aftermarket RM parts at the Honda shop about 1/2 mile from my house. The parts guy there gives me pretty good discounts off most of the stuff - I bought one of the expensive plugs last year for about $20. Still expensive, but I only go through one or two plugs a year and haven't fouled one yet.

Chili - maybe you're right about the clutches now, but I haven't been particularly impressed with mine.

Love the rest of the bike, though.

it is because in some rare cases the ground on the cheap $ 2.50 plugs broke off and slammed between the piston and dome of the head which is very bad.
