Funny - I checked my plug gap during the first service and guess what...they were gapped at 0.9 mm from the factory. Lol
Yep, and you'll have to also change the plugs from CPR8EB-9 to CPR8EA-9.Another thing to consider is that for both plugs, the "-9" indicates that they come pre-gapped at 0.9 mm. Although the Moto Guzzi owner's and service manuals state that the spark gaps should be 0.6-0.7 mm, I have found that 0.9 mm works better, on both my previous '13 V7 Stone and my current '16 V7II Stone.
I have some questions for iridium plug users. If you chose these because you want them to last a long time, don't you still have to remove them every time you adjust the valves? Eventually, the metal gaskets will flatten and you'll have to replace them. Are they even available separately? How hard is it to remove a flattened gasket from a spark plug and put on a new one? Thanks, just curious.
Hi Sib, I got the point but I' don't know how to answer...Simply because I use iridium spark plugs just for a performance (and not for long lasting..) purpose, and so I usually replace them every time I adjust the valves....Yes, I'm crazy ;-)
Before I replaced the plug caps on my V7II, the plugs were sooty. Having replaced the plug caps with NGK WD05F -R the plugs have been running pretty clean. Were the OEM plug caps misfiring? I didn't detect that while riding. Perhaps a bit of a mystery.CheersBrian C
Curious about why you selected the red caps (signified by the "-R" suffix) instead of the black ones. Hotter spark?
I wasn't having any issues on mine - only 8000 km on the clock. But heading down to Staunton, Virginia for a 5 day ride in the area (about 3000km), so doing some preventative work. I did the all-metal fuel filter also, although the jury is out on that one. I guess it depends more on where you live, and the gas available there. In any case, it's one less thing to worry about. And yes, the tank rubber bumper guides were not very tight, so fixed that also.
Or the CR9EK plugs (factory gaps) with the XD05F caps my V7S seems quite happy with for the last 80,000 km.Copper core wire is recommended.
NWNGK Racing have HT cable & caps in a pretty shade of red. Check them out in their Racing section.
Did you ask them to update the map to a crappy factory one? I would be pissed if they did that and I lost the Guzzitech one.
Hamlin takes fantastic care of us when needed.I feel for those who don't have a shop like his.I don't ride 400 miles for nothing!
KOF and I both had our ECU's re-flashed way before Todd's new map tool was available. I have no reason to be "pissed" about losing the guzzitech map.
Perhaps you should had backed up the map using Guzzidiag. Not for distributing to others, but only for the situation that you have just encountered.
