Hi
Bought a 90 phazer last year//has 800 miles on it//cleaned carbs //new plugs//...idles good ,works good at wide open throttle,but bogs on acceleration?? seems to be a flat spot at 1/4 throttle//run 2 or 3 tanks of fuel in it//no better or worse? plugs look good//started on 5th pull after sitting all summer//bog still there this year..
Thanks,Denis

Check the clutches. Make sure they are not sticking/binding.

Id suggest checking the TORS (throttle override sensor) as well. Its pretty common for Yamahas to act up like that when the TORS isnt working properly.

clutches seem to be working OK//not sticking good top end ect.
Will check TORS[bypass it] and let you know how it runs.
Thanks,Denis
