"I'am trying to troubleshoot a problem with my Enduro. It is a '91 bought from Campbell River Yamaha in '94. I will be cruising nicely at about 3000 RPM and it will completely bog down as though it is starved for gas. It is not over heating, has a good stream of piss but will only come back to life after trolling around for 10 or 15 minutes. I have changed the fuel pump diafram, bypassed the fuel system, changed plugs, cleaned carb but nothing has helped. I treat it like a kitten and have had many hours of great boating but I'am at a loss. Any help would be appreciated."
