tach issues

David, Still sounds like fuel starvation. I earlier suggested you need to check the carb vent hose. smile. I have not changed my mind. and you need to do the t-mod as well. Put a clean piece of tubing on the vent line and see if you can gently blow air into the carb, as well as make sure the vent line is 100% free of debris or bugs. Bugs love vent lines. eddieM suggested the inline fuel filter as a cure for that as well. I sucked a bug through my vent line and it 'parked' on the main jet. Very annoying to happen at night, 15 miles from home, but it would still pull the bike at 30mph in a 65mph road. YIKES! Another thing you could/should do is remove the carb drain plug, (right side of the bike, just below the exhaust header) drain the carb bowl (preferably on a clean white rag) and then with a rag to catch the splash, crank the bike so the vacuum petcock allows fuel to fully purge float needle and the carb bowl. NOTE: do not be looking at the drain hole when the bike is cranking; you might get an eyeful of fuel. If all this does not work, and you become patently exasperated, send me your instrument cluster. I could use the speedo head..... revmaaatin.

I tried to make the engine stall by plugging it with my finger at idle and it ran for about 30 seconds before I gave up. I guess I could try plugging it longer but I think if it's air pressures affecting it at speed in a cross wind it would be a completely different scenario. I guess I need to get a leaf blower... > > Photo: > http://i1248.photobucket.com/albums/hh482/nichodr/C360_2012-03-28-12-17-35.jpg > > > > ________________________________ > From: eddie > To: KLR650 list DSN_KLR650@yahoogroups.com> > Sent: Tuesday, May 29, 2012 1:58 PM > Subject: Re: [DSN_KLR650] High Winds and Coasting Issue > > > > > The only other thing I can think of is if you've rerouted the carb vent > line to the left side or done the T-mod and air pressure is pushing > in the hose and messing with the carburation.
