I have recently bought a 2007 NORGE (2 valve) with 18,000 miles on the clock. Â The engine runs well but when accelerating or going up hill at motorway speeds the engine appears to 'pink (suffers detonation) on anything less than full throttle.
I have only used one tank of fuel thus far which was regular unleaded. Â Should I be using a higher grade of fuel or does something else cause this problem
I’ed try fuel with a with a higher octane rating first and see if it makes a difference. My Quota pinks on load using ordinary unleaded but is okay using Shell V Power. (Other brands available!)
My 2006 Norge does this. It used to bother me, but seems restricted to hot days when I can’t be bothered to change down a gear when I need to wind it up.
Personally, I DO think Super Unleaded makes the whole bike better.
It’s a Guzzi, it’s teaching you how it wants you to ride it.
