The engine has loosened up nicely, and she slips eagerly and effortlessly up to sixty on the straight, and seems quite keen for a bit more. I'm way more relaxed on this bike now, leaning faster into the curves and nicely in control of the slow stuff.I had a look at the plug before I left and cleaned it up. It was pretty sooty, which surprised me. This is a lean burn engine, no? A little bit of black smoke when she starts, not much, and the inside of the tail pie is sooty too. Is this your experience?
Singh, yes it is the original Bosch plug, with the two contacts instead of the old type single adjustable contact. It is black but not clogged up. I checked it because the tickover was occasionally a little hesitant, and was racing a bit I thought when I returned from my evening ride on saturday. When the loan bike conked out it was because the plug was very sooty and clogged, but that bike had been started every day, run round from the back to the front of the showroom, and switched off, so only really run on choke. This is definitely not the case with my bike, which runs for a minimum of thirty miles but often for over one hundred, except for occasional startups in the garage to impress visiting friends!
