My 81 cb750f isnt running so well at high speeds. When I'm in 5th gear on the freeway it seems to lose power around 90mph.. an i have to let the rpms back down and baby the throttle, it seems to catch and bucks a little bit, like there's too much air comming in as opposed to fuel. For a minute or two i cant go over 65mph before it catches again... then i have full power. Any ideas? thx.
