WHICH PLUGS? CR8EK, CR9EK or CR8E
« on: April 06, 2006, 09:07:05 AM »
Hi, just a quickie this time.  WHich plugs do you use?  I used to use NGK CR8E in my '91 bandit, single ground electrode, they worked fine, and were half the price.  

I how have a '96 V/VS 4, and need to chage the plugs, they dont have NGK plugs in at the moment, i forget the make.  NGK reccomends, the CR8EK, but others say the CR9EK, which is best? Does anyone know the difference between them.  Also what is the advantage of having a twin ground electrode, apart from making you wallet lighter!!!

Oh also what gap do you run? 0.6mm?


Cheers

Ben

The number in the middle is the temp of the plug.  Lower numbers are hotter.  For the non-v US models, the 91 and 92s call for 8EKs.  The 93 for 9EKs.  The K at the end indicates the dual tip.  I run the single tips (CR9E in my 93) at gsxr400racer's suggestion.  Having said all of that, i have no idea if the v models need something different.  

Gap - I always check them against whatever the manual calls for.  They're always perfect right out of the box.

I dont think the v need anything different, a local motorcycle part dealer suggested the 8EK when i had my '91.

SERVICE MANUAL SAYS CR8E 0.7 - 0.8MM GAP for the '97 v.

Does everyone agree?

CR8E is good enough, dual tip is handy when you're pushing the bike to the limit i think, like rich mixture and heavy loads. With 2 electrodes the chance of getting a spark is twice as high, thus the risk of getting a misfire is halved. Statistically and assuming my statement is correct.  :wink:
