Iridium Vs Copper
Hot Vs Cold
Apparently the race kit manual says to install CR10EIX plugs in an engine fitted with the race kit internals and full arrow system.
I'm running an '06 race bike in 3 different classes per meet, usually completing 20 practice, quali or race (5-7 laps) sessions per weekend plus a practice day beforehand.
When I got the bike it had CR9EIX plugs fitted. After a couple of years I fitted CR9EK plugs (when I checked valve clearances) as I couldn't see any benefit with iridium plugs.
The bike has the following engine mods -
*Stock headers with cat and ex-up removed
*09 velocity stacks
*Wheel detent kit
*Billet oil cooler
*Manual idle adjuster
*Manual cam chain tensioner
*Crankcase vents to airbox
I believe it may also have had a thinner head gasket fitted and the backlash gear removed (or modified) by the original owner.
Any sage advice would be appreciated. TIA
