Re: went one hotter on plug is this ok

One heat range hotter probably will not cause any harm, but its a case of treating the symptom rather than solving the problem. If plugs are fouling, something is wrong. It could be carb setup/adjustment and tuning, a low voltage or electrical component, or it could be an oil leak or a compression and gasket problem. I would try to determine what is causing the fouling.

I'll be very surprised if champion plugs will perform as well or as long as the NGKs 8O As Earl stated...something else is going on if you're fouling B8's and should be checked out and corrected.
 
NGK B8-ES spark plugs have been conclusively and definitively proven to easily last at least 12,000 miles on a properly running GS. Most of us change them once a year, but only because we need something to do. Heck, they're only $1.79 each at Advance Auto.

Anyway, the NGK plugs definitely ain't the problem. They're simply collecting the evidence of the problem for you. Changing the heat range won't make the least bit of difference with fouling.

If you know it's just running a little rich or burning a little oil and you'd rather just ride the bike and screw in new plugs every so often, that's definitely understandable and reasonable.

But if you don't know why the plugs are fouling, it would be best to track the problem down ASAP in case it's something more serious.
 
I've got over 20,000 on my NGK B8ES plugs since my rebuild 6 years ago. They look fine. Something else as stated above is causing the problem.
 
IMHO, the only thing that champions work well in is chrysler products. Ive been an auto-tech since the late 80s and have found over the years that engines like the plugs they were designed for. so your GM product gets ac-delcos, german cars typically get Bosch, ford gets autolite, and your GS need NGKs or Nippondensos. The engineers that designed the ignition system did so with the plugs that got used in the car, and any changing brands usually leads to decreased performance of the system.

Secondly, the heat range of the plug is one of the most misunderstood aspects of tuning IMO. it is not a hotter spark as many people believe, its simply a measure of how fast the center electrode can transfer its heat to the cylinder head. alot of times screwing in a hotter plug will just lead to preignition as the electrode runs too hot. the hotter plug is usually only adviseable for use in extreme cold conditions.

go back to stock plugs, or the ND equivelant, and remedy the initial problem. I can't tell you how many times taking the wrong plugs out and putting the correct plugs in have fixed minor driveability issues in a vehicle, but enough times Im willingto follow manufacturers recommendations on the matter.

to echo earlier comments, if you are fouling plugs, something else is wrong with your bike. otherwise you should only haveta replace the plugs when the electrodes are burnt down to the point they are out of spec. many thousands of miles for certain.
