False. Use the factory recomeded plug.

.030 over will probably not get you to 1075cc unless it began at about 1074. Unless it's 30 inches over................. :silly:

b8es's are the right plug going one heat range hotter like you have won't hurt it if your just cruising but for extended high rpm use i'd go to a colder b8 or b9es plug. and no that wont be why your bike is hard to start.

Kawi factory specifies the B8ES for the fours and the B6ES for the twins. My twin will foul a plug if you go to the colder ones in city driving which (I assume) is why kawi specs the hotter ones for the twins. Some people say you can go one range colder for constant highway driving.
