ct265R spark plug

[dustinb]

i have a CT pro cross 265 cylinder and i dont know what spark plug to run. riht now i have a BR8ES from my blasters but im not so sure that is the plug to run in this bike. it hasnt given me any problems, but i dont want it to either so if you could help me out it would be appreciated

BR8ES and BR9ES are the most comon R plugs. im the only person ive ever met that runs anything like the BPR5EIX in an R. (actually i run the bpr5eix in a blaster too)

yah i run one of the 3... b8es, br8es, or bre8eix i think... one of those iridium plugs...

I run a BR9es, but most of the time I run the BR9eya, and I've had good luck with that one.

I just wanted to ad to this . alot of people think that the heat range is how hot the plug sparks . That is false The heat range is the plugs ability to dissapate heat off the insulator. and may give false jetting readings . a rich motor with a hot plug will read leaner . or a cold plug with lean bike will read richer . so i would stay in the 8-9 heat range . i hope this helps

yeah he is right. a hotter plug resists fouling more and once it gets up to temperature it does make it apear lean.... the best feature is making it so i can put around all day with the four stroke guys and not foul a plug.
