Today I spen a few hours riding the SFC1000, bringing a few tools to take the biek partially apart and inspect spark plugs, which have had a tendency to be soothy.
So, new spark plug caps and no Castrol Valvemaster and on the the motorway. After some driving I just turned it off, went to the roadside and inspected the spark plugs, which were oaky. A Little Black and Brown on the electrodes. Seemed clean enough. So not a problem with the #118 mail jeg I suppose.
The reassemble the bike and off to the back roads, where you use a lot more the idleing, low register, acceleration, deceleratio and so on. Soothy plugs.
The non-presence of Castrol Valvemaster+ is not the cause.
Tomorrow depending on dry roads, I'll have a go with pilot jets going from standard #65, to a set of #62,5.
By the way, it takes only 4 minutes and 10 seconds (and a further 1 minute and 20 for the fairing if need be) to calmly and in good order, find the tools in a backpack and undo the 10 bolts, the tank rubberband, the seat and tank, wires and fuel hoses, plus the tank breather, to inspect the spark plugs. Not bad I think, and it's dead easy. Try that on a Honda cbr1000rr fireblade.
Does someone have experience on changing the pilot jets on a sfc1000?
Gotta' love your Laverda
