Which Champion plug do you use please? I looked on the European Champion website and RE isn't listed.

Currently in my 2005 Bullet 500ES "Iron Barrel" I'm using a Champion N4C instead of the "NGK BR 8 ES" suggested in the Owners Manual. It seems to be running sweetly enough, as shown below after over 4,000 miles (about 6,500 km)--maybe just a tad "rich". However, if you are riding an AVL, Electra or later UCE, you may well need a another grade of plug. There is no shortage of spark plug cross-references online to help you find the right one.

As I have mentioned previously in these Forums several times, I've never had much luck with NGKs. For some reason my Norton twins never failed to kill them dead, usually in just a matter of weeks.

Thanks, I'll have a search on one of those sites you linked to.

           I know this isn't a spark plug thread so I'll keep this short.

           Just let me suggest that either your mixture is way too rich OR that heat range of 4 isn't right. And no, I don't know.

            The condition of your plug would not make me happy

The recommended NGK for mune is NGK BP6E. That site said "There are 360 replacement spark plugs for NGK BP6ES"

Sorry - don't believe that!

Well, you're forgetting the whole Chinese Bongo Dongo and Hung Far Low multi-brand families of quality spark plugs, drill bits and 2-stroke "Pink Dragon" marital aids, putting the bang in your wang or a tune in your poon since "The Four Great Strokes" reforms of 1988.

           Why do you find that so hard to believe ?

           Why do you find that so hard to believe ?

I cannot see why Champion, for instance would manufacture this range:

Champion 300, 8415, 9FYSR, N10Y, N11YC, N281YC, N66Y, N79Y, N89GY, N8Y, N9Y, N9YC, N9YCC, N9YCX, N9YX, OE001, OE001/R04, OE001/T10, OE22, OE22/T10, OE109, RN11YC4, UN79Y, stk300, stck302, stk322.

If they were all exactly the same.
And they are not all exactly the same, then they are not all an exact replacement for a NGK BP6E, are they?

EDIT:
Got word back from Champion.eu, they say they have no details of Royal Enfield EFI bikes but by cross referencing, they have come up with Champion OE081/T10

Yup...Lotta crapola to unpack there from the good folks at Champion--mostly part number codes for OEM equivalents, variant materials used (copper, platinum, etc.), with or without resistor, and slightly different heat ranges. Despite the ultra-exotic one Champion recommended (i.e., expensive special order), unless you're insisting on uncompromising originality in your restoration of the very last running Romanian-built Dacia Loogie, what you should probably try is Champion's humble N9Y or N9YC (for copper), either or both of which should be readily available from your local auto bits shop for about the price of a pint. Here's a cross-reference of the N9Y TO  other brands listing the NGK BP6ES you mentioned. Just screw one in for a couple-few hundred miles, and then check how it looks. If she's been running well enough and the plug looks good (maybe not quite as dark as mine, but not too white and "melty" either), then there you go. If you're wise, you'll then get a spare for the tool pouch too.

Just a little tip from your Uncle Bilgey: Whenever you're screwing in a spark plug, give its threads a little dab of oil, just a drop or two of kindness from the dipstick is fine, and go REAL EASY on the torque. Nice and easy does it!

I remember in the old days 'everything' used an N9Y

             It is no great earth shattering revelation here about the fact that there may be dozens if not hundreds of plugs that are an exact or almost exact replacement for any given plug out there plus the fact that there may be (for example) a plug out there that has Kawasaki's name and part number on it that is exactly the same as some (or even Manufactured by) NGK or Autolite plug you may be cross referencing. There is a lot of homework which must be done nowadays to figure out ANYTHING.

             One of the big advantages of these (and other cross references) is that if you're stuck for plugs in Bumfuque, Tajjerkistan (or Someotherstan) you may find "something" that will work perfectly fine and be OK no matter whose Name or Part Number is on the bloomin' thing.   

              Now I am getting off this thread which is supposed to be about an oil leak.
