What plugs and gaps are you guys with FCR's and Dynacoils running? Are there any real noticeable benefits of running anything other than the stock plugs/gaps?

Most go up from the 024" to 030" on gap. Can't say it makes a big difference but it makes sense to me to run a bigger gap with this set up. Same plug NGK DPR8 works but one range cooler if you've got hi-comps and such.

i found a bigger gap on my 600 gave the same cold running issues with the dyna coils that it does with the std coils. don't have fcr tho. altho i have green coils (5 ohm?) which may not be 100% correct for the application.

you can get some dual ground electrode plugs that may help - there's a DCPR8EKC which i nominally have for bmw 1200's and there's JR8C or something like that too from memory. also ngk make a v groove ground electrode plug that's meant to work a bit better in "dodgy" combinations for want of the better term (high demand?).

Brad,

Everything is running fine with the stock gaps, no starting or running issues at all. I was just curious if going with a wider gap would provide any benefits.

I have Dyna Coils but stock everything else (carbs, airbox, paper filter, exhaust) and my gap is 034 with Iridium plugs. I went with this after reading some other posts with guys going as high as 040. The bike runs better than ever! I will eventually go to FCRs but just adding information to this thread.

i was using std style dpr8ea-9 plugs. with them they run better with 0.6mm gap compared to 0.9mm ime. but the iridiums have much better spark concentration.
