I have a 2000 model yamaha c60tlry. the engine runs fine at idle has a good
smooth run up to about 4200 rpm after a few seconds the engine loads up then runs rough at around 3100 with no change in throttle position. Putting
the throttle in neutral for a few seconds (maybe 10) the situation repeats. Good run up to around 4200 then bogs down to about 3100. I thought it might be water in the fuel so changed the fuel/water filter, checked and emptied the internal filter and same results. Have had some issues with
fouled plugs so even changed them with same results. Any ideas
