I'm at about 7.2 k miles - not even broken in yet. Hardly any visible wear on the cam chain sprocket.jorgeno wrote:That was not so bad, how many mileage does your bike have?
Mine makes a knocking noise too when it's hot (and only at idle). In my case, I don't think it's carbon; through the sparkplug holes, I can still see aluminum on my piston domes. I was originally worried about it as I had a KZ1300 and it made a similar, but louder, knocking noise just before I spun a main bearing (the KZ was making a knocking noise all the time, not just when it was hot). But, I've looked at some YouTube videos of running ZN's and they were making the same knocking noise too so maybe it's normal.jorgeno wrote: It makes a bit engine knocking noises when it’s hot. The manual suggests carbon buildups. Maybe becaus long time without adjusting the valves?
Not sure but someone here will have notions on that.jorgeno wrote:That was not so bad, how many mileage does your bike have? I’m wondering if the cam chain sprocket can estimate the mileage? And how far does Voyagers-bikers travel before it’s necessary to do some engine overhaul?
