My new to me pinky isn't running right, sputters for a bit then surges with the power coming back on. I'm going to cleam out the carb but would like to have some spare plugs for future problems.

So which model plug will work best with this bike, someone posted a B6ES plug cause it runs hotter, but also read somewhere the B8ES works too.

What is the stock plug #, and what should I be running with, maybe a hotter one?

Thanks Guys.

hi stench just to let you know that i run my pinky on bp6es plug without any problems although when i bought my bike it had a bp7es which did not last very long,remember to change it on regular basis it does pay,good luck and enjoy your riding

The best plug for the Yam is an Iridium BPR6EIX, the P stands for protuding nose which you can get away with, however the most important thing is that you run an R plug. R stands for resistor and is essential when using cdi ignition as it cuts out interference from the plug.

So the standard plug is a BR6ES but the the best is a BPR6EIX.

Have a look at www.sparkplugs.co.uk loads of good gen on there and cheap too!

I have always used BR8ES plugs, no problems. I would say that there is dirt in your carb, doesn't sound like a plug problem to me.

Thanks guys! totally cleaned out the carb last night, installed new plug NGK B6ES, and filled with new fuel mix.

She runs great now, except for the throttle cable seems to be sticky sometimes.

Does anybody know the part number for the throttle cable cause I don't have a manual just yet??
