what choice of spark plugs are there for fuel injection r1.

Bought my Carbed R1 plugs from this lot.
Good service,
f you go through the menues
they will list the correct plug for your engine.

The information regarding spark plugs is best obtained from the manufacturer - not a third party database.

Course I'm bound to say:

NGK SPARK PLUGS

are your best choice.

Don't know exactly why you're asking, but I'm running ZX10 engines (old ZX10, I'm not that rich!) & went 2 heat ranges hotter to stop plug fouling in the winter months when moving the car around, ran the same plugs thro' the summer with no ill effects.
