about every 20- 25min my bike goes throgh spark plugs. the carb is jetted rite and the gas mix isnt to rich. one of my buddys has siad that Ignition Rewinding might do the trick. any input

 

What plug are you running? What gas mis ratio? Don't overlook a dirty air filter.

 

It could be weak spark... Try gaping the plugs at 0.020.... and dont forget 2-strokes are throttle happy[img]i/expressions/face-icon-small-wink.gif[/img]

 

i'm running br9es 32 to 1 gas. Can too much oil on the air fliter cuase these problems

 

i run 40:1 on my r and it doesnt foul plugs, i dont know if too much oil will cause it to foul but i do know that a dirty air filter will and i know from experience that too much oil causes your airfilter to get dirty realy fast cause the dirt just stick real easy.

 

br9es is too cold a plug. Switch to an 8. 32:1 should be fine but I run mine a tad leaner as well. A dirty air filter will also reduce plug life.

 

thanks i'm goin to clean off the air fliter i'll tell u how it goes

 

also dont lug the bike. that'll kill spark plugs on a 2 stroke as well.

i think thats what dragracer was trying to say.

 

you should run 40:1 with a decent oil. 32:1 is ok but if your lugging around it will foul plugs. remember more oil in your gas is not richer it is accully leaner (air to fuel ratio).

i ran my bike 80:1 with redline 2 stroke oil

 

I use a br9es and run my fuel @ about 35:1.

I had similar symptoms a few years back.

Bought a new air filter and it cured right up.

The foam on the filter was coming apart and getting sucked into the chamber. I noticed burnt sooty crap all over the plug.

It was kinda old - a circa 1985 K+N...

I hope that fixes your problem.

I doubt its ignition. On 250r's - they either work or they dont.

On the oil bit - I use some left over Golden Spectro from 1990.. It works.
