2 wheels forever
Hello. I'm new to the boards. Thanks for having such a great resource.
Anyway. i just got my 1979 xs650 about a week ago. ive been doing mostly cosmetic changes to start with, since my bike is a one kick wonder.
yesterday i opened up the pipes in the back as so many have, and now it sounds like my bike is flooding if i get on the throttle hard. if i slowly roll on the power, i have no issues. its only if im revving my engine or trying to get on the throttle. its only for the first 1/4 to 1/8 of my throttle. if i can get through the rough spot it revs just fine.
ive tried messing with the idle mixture screw. (i think) the one on the side of the carb tucked under where the cable links to the carb. it is my understanding that since it is near the front of the carb it is adjusting the amount of gas/vapor that enters the engine. not actually adjusting the amount of air.
ive tried both 1/2 a turn from fully screwed in, to about 3 full turns out. all it does is slightly change where in the my 'dead spot' is.
help. do i really need to re-jet with such a minor change in back pressure? or can i use what i got and do some more adjustments.
Please help.
