Just interested in what others are fitting to Oil Cooled GSXR1100 1992 Engine (1127cc twin lobe)
I have used JR9B single & dual, D8EA and always use only NGK.
NGK list a plug noted as NGK7082 and on the plug from what I can see in brochure has FR5EG printed on it.
they appear to be Iridium style of plug, does anyone use these?
Oh............ engine runs STD cams but around 12.5/1 Compression, 40MM Carbs with K & N Pods and 4 in to 1 and is bored to 1216cc.
Dyno'd at 148 RWHP & 92 ft/lb torque.
any suggestions or thoughts would be appreciated.
