Sparkplugs for nitrous
Hi last question on my new setup , Im putting on a dry 40 shot and a hub and will get a dynod second map for the nitrous , Im spraying in the ram air before the filter . What plugs are best?? Im leaving the timing stock . I just had a box delivered from Schnitz , and this weekend will be installing a puig DB , PMR tether killswitch , Brocks clutch springs , sliders and stand spools , hub , extra fusebox , schnitz air filter cover. , Dynotune window switch ,and bottles , etc . While Im at it I will check out the tip over sensor I hear you guys on about.! This will complete my project except for those BST rims that my wife says are at least a year away . Thanks again for all the help over the last month , It has made choosing the right parts a lot easier . I will post some pics of the blackest 14 when its all done.

Many prefer the larger dual strap electrode of the CR10ek, and I definately would run the cooler #10 plug of either series either way.
Tighten the gap to .020 ~.025 to prevent flame out.
Your cylinder pressure increases dramatically with nitrous and increases resistance to arc across the plug.

Thanks again Dubious , got hold of those plugs today. Was a busy one , installed my bottle / solenoid / window switch / new fuse box / speedo healer and started on the hub .Another question as Im new to doing my own work , The pressure input harness supplied with the hub kit is for turbo only ? so does that mean just dont connect it to anything ??? Also is the supplied map selection switch waterproof ? Same with the speedohealer remote button , is that one waterproof? If they arent I think I will swap them out . I am an obsesive / compulsive silicone and waterproof type of guy.

I never used the pressure input harness on nitrous. It is for turbo.
The switch and speedohealer are water resistant I beleive.
I used to bag my lcd or removed it when hitting the bike with pressure washer, but never had any issues when riding it home in mild rain conditions.
Never had any problems with any of it.

Plugs too rich?
I bought a set of CR10EK's yesterday after reading this thread. I have a 50 dry system that i want to use for T&T (its to much for the 950 class).
Question is will these plugs be to cold for running without spray? Took the old plugs out today and they look awful rich already,opinions?.
bike sees only track use no street use so its at WOT most of the time.

The porcelin looks not bad.
Are you running pump fuel?
When the porcelin looks clean and the the rest of the plug looks dirty, allot of the time its due to dirty fuel (pump gas)
How many miles, what map, what afr?
I tried using Brocks Maxton map, and his pump gas track map, but went to his street map and it cleaned things up.
Are you using a second map for Nitrous, have you tuned both on the dyno or run AFR?

Pump fuel,this was dyno mapped for the Tsukigi exhaust.
I bought a used Brocks sidewinder that i will be running this year,so once i get it all together i will try one of his maps.
I would like to get it to the dyno again for a nitrous map too. I have the LCD and hub so i can switch maps(think i bought it from you?) Stu.

Yes , fine to run.
I ran mine 7000 miles at a time.
Pump fuel leaves alot of carbon on the plugs sometimes as STU is seeing.
(looks a bit rich too)
