Plug Question

Spark plugs on the GSX1100F keep fouling on short journeys, even when
I let the bike warm up. It doesn't appear to be as bad if I use LRP.

Boss suggested using hotter plugs, so I looked into it. Now, most
sites say I should use the JR9B, but on www.suzukicycles.org it says
that *UK* model should use the JR10B, with other models using the
JR9B's. Why is this?

Would using a JR10B make much difference?

 

Wet fouling, presumably...?

Does it /have/ JR9Bs at the moment?

The advice given makes little sense... I always understood that the lower the number, the
hotter the plug...

Mmm, check this out:

and then, this:

Granted, it's the US site (the Japanese "English" one is rubbish) and they
do confirm that, for the US anyway, the JR9B is the one to use.

Therefore, the recommendation to use the /colder/ JR10B doesn't stack up...

Sorry, got it wrong in my head[1], its the 10's I have, should I
replace with 9's?

[1] I'm doing 5 projects at the moment and the Boss just gave me
another one [2]
[2] The lack of beer doesn't help either (7 days and counting)

 

In which case, I refer sir to my previous remark.
