big bore plugs?

[jas250r]

breaking in new ct 350pv. they say to br8es to break in, then switch to a few different plugs. i forget what the other 2 are. why do you need to run a cooler plug? and why not just stick with the br8es the whole time?

Stay with the BR8ES plug gapped at .018. Set up the carb to be on the rich side for at least the first tank full.

I'm running a stock cylinder with Boysen RAD valve and a Lectron carb, my bike seems to sputter with a BR8. Runs perfectly with a BR9. I do believe different the years called for different plugs, but obviously if your running a different motor then it wont make a difference.
