Anyone experimented w/ different spark plugs?

[Quinton]

I am wondering if anyone is using a different plug than what the factory calls for my 92 cr250 and your machine is running better? I don't think it will run "better", but you know what I mean. Just curious about Splitfires or Bosch platinums, etc.

Thanks

IMO the Splitfires are a waste of money. My kx seems to run about the same whether I run a BR8 or a BR8EVX

Splitfires make excellent plumb bobs

Ditto!



If you want any change, pipe, jetting, and a # of other changes. I would start off with reeds and a topend re-build along with(Erick's rebuild kit which includes all)

About all I can say is take a real close look at this site. You will find sooooooo Much info it will make your mind explode! :thumb:

I have run 3 different plugs in my 02 YZ250.

NGK BR8EV
NGK BR8EG
and Splitfire tripple platinum plugs

When I bought the bike new it had the BR8EG in it, the plug fouled after the 1st hour on it. The BR8EV was alittle better plug. It did not foul as quiclky I could get about 3 rides out of it. But once I started to race I was basicly i was changing them after every race day. I then started to use the Splitfire TP as it was alittle cheaper then the NGK. I did not really notice any real performance difference except the NGK EG was really prone to fouling. My local yamha dealer also confirmed this when I went to buy some spare plug. They told m to either buy the EV or a splitfire.

I have been using the splitfire up until this weekend and it has been ok to me.

... or you could have bought the correct jets :)

I've had my bike for almost a year now, i'm on my 2nd plug and i ride about 4 days a month.. Been running br8evx's, i never liked spiltfires.. Try jetting your bike..

denso plugs sold at autozone are the plugs that i run in hare scrambles and i have never fouled one on my 1998 or 2001 cr125's pluse they are about $1.50 good luck

You could also try going to a hotter plug, if you find yourself fouling alot. In my 2000 YZ 250, if I am running in the woods, lots of low RPM, I run a BR7ES.

Personally I can't tell the difference between the standard NGK plugs and the "Racing" G plugs, but that is just me.

My CR250 doesn't know the difference between plug types. Just go by the Honda manual for recommended or alternate plugs. I've only had one plug foul on me, when it was jetted too rich. I always carry a spare plug when I go on a long (1 hr+) trail rides through the woods, but never needed it.

Glad I read through. I was about to post the same thing :scream:
scsary now I'm thinkin like Rich. The last time we had this debate we were on opposite ends of the spectrum.

As long as its sparkin, a spark is a spark.. I've been running $1.50 Champion plugs from autozone w/out a problem in my '88 RM250..

 

[MikeT]

I find the plugs that run the best in my bike are the ES plugs..... Because they are cheap! :) :)

lol, Rich :thumb:

You can have any of my spare plugs laying around that I've never had the chance to use, since I've never fouled one (although I threw the break-in plug away for good measure). I've even got a splitfire you can have--looked at it a while back and was horrified by the obvious lack of quality. It's special "V" strap looked to have been cast over a campfire by a drunk cowboy with a pair of grappling pliers. ;)

I find an Autolite 404 works good in my 88 KTM and my 01 CR. If the mixture is set right there is little difference to an NGK but if it is rich or slow riding, the 404 will run better without blubbering. The heat range for the 404 is about the same as an NGK 6 but I have yet to burn or foul one.

Splitfire plugs make for good sinkers when you go fishing .

I just sold my 92cr250 2 weeks ago and I found that the ngk br7es worked great.It never fouled and seemed to give the bike a little more snap off the bottom. In fact Eric Gorr recommended this plug back in 92 in dirtrider magazine for the cr along with some other mods to increase low-end power.I live in british columbia so it is usually damp and cool here and the plug was clean and tan in color.I don't know if he'd recommend it for heat and sand dunes.

If the bike is jetted right for the gas/oil combo and weather condutions & if the reeds are good, the bike should never foul a plug, no mater the kind. I'll let you know when I get there.
