125-200cc iridium plug or competition plug for 125?

Hi everyone, just a quick question of which type of plug you prefer? which 2T machine you have and why????

I like the Irridium in a WR just because the ignition seems kind of weak. I don't know if I would still run them if I had a CR.

Iridiums are very cheap when you consider their longevity, better spark- equals better ignition, on a 2 stroke the faster operating temp means less fouling. Better ignition means less pollution. I am convinced mpg is marginally better. BUT most of all they start better esp. when its very cold. No issue really. I have used them from onset on my 4T and 2T and will never go back to a standard type plug.

Where are the Roost Boost and iCat options?

I just tried a E3 plug, seem to give it more bottom end throttle response and it was only 7 bucks cdn, the BR9EIX iridium cost me around 12.
Plus E3 sponsor the Endurocross

Im running on this and my bike need only one kick to start every morning. i change the plug every 5000km or so.

interesting Mr_X, how is the top end of yours in that combo???

Basically i have a SM125s so it mainly runs on road, i found for everyday uses iridium does a great job esp. on starting, low end and mid range
however its lacks a bit of top end compare to comp. racing plug

the racing plug does well from mid to top end but starting and pulling off is bit weak, its really good for friday night ride, have fun and high speed etc.

theres always give and take but let me know what you think and prefer

hey,

Im using Arrow full system and rear Ohlins shock (prefit from Honda CR125), NGK race cable, Denso Iridium spark plug, 47T rear sprocket, Maxima castor 927 2T (10ml to one litre of RON98 petrol). My bike can hit 157km/hr max. You should try some of the parts stae above, especially the Arrow system, which is road legal.

Icat and Roost boost are worthless gimmicks. Good oil is not a gimmick. I am not sure what Kelly is calling Fancy Oil ? But there are plenty of bearly passable oils out there that I see being pushed on the KTM sites . Iridium plugs are supposed to be better and last longer. I can't swear to it but I don't see a downside if they last longer even if they do cost more at the beginning.

Anyone used the BR9EIX irridium and BR8EIX irridium ?
Is the 8 better for woods as described in 125 tuning index?

Iv e heard reports that Irridium performance gain only short lived - 1 - 2 hours
from a Kart racer

I believe in the advantages of the iridium plugs but haven't found a need for one yet. They helped with a plug fouling issue I had on the KX250 but I am still on the original standard plug on my WR144. That plug has lasted through two break-in (125 and 144) and 25 hours of riding. If there is a need I'll pay more for the iridium but for now the standard $3 NGK is working fine.

I just haven't had a problem with plugs to bother swapping out. I got 70 hours out of my first plug and swapped it when I put my 144 kit in just because it seemed like a good idea.
