Crossing plugs?

Hey all,

I am currently running a BR8ES plug in my 250.

I am also running a BR7ES plug in my 1100 Kawasaki jet ski 2 stroke

Now people say a 7 will melt the engine but the ski doesnt seem to mind the hot plug

how would the CR do with a 7?

has any ran a 7 in there CR?

did it run better or the same?

i wouldnt run that br7es probably too hot. I would go to a cooler plug before a hotter one.

I you are only putting around a 7 would be ok as long as you never put a load for a long time. Youll overheat the tip of the plug potentially causing it to fall off over time. I use a b8 and it runs very clean.
