Question about 1988 Yamaha XJ 600
Hi... if you have vacuum cabs... Have you checked to see if the vacuum on the fuel tap is working correctly.. Take the fuel pipe of the carbs, put the fuel tap to on.. If its a vacuum tap there should be no fuel coming out. Put the pipe in your mouth and suck on the pipe, if fuel comes out then stops it seems to be working. Also check the diaphragms in the top of the carbs are not split or have any pin holes in them. You can do this but holding the diaphragm up to the light.. (If they are vacuum carbs).. You can aso check to see if the carb rubbers are leaking between the carbs and the engine.. You can do this by starting the bike up and leave it ticking over. Get some carb cleaner or WD40 and spray it onto the rubbers between the carbs and engine. If the engine pics up speed (revs go higher) then the rubbers need to be changed.. Hope this helps you out...
Good luck.. Tony.
