have almost 10,000 mi. for the last 1000 has had a slight fuel starvation at wot. at first thought it was the rev limiter, until I watched the tach. no problem up to like 7/8 throttle, just half the time at wot it starves enough to notice. the only filter I see is on the pump. anyone else experience this?

Have you checked your air filter lately?

no, its a snow screen, doubt its plugged, plus I blocked the inlet off with mechanics cloth when new to keep critters out and its starving, not chokingdrag123 said:sgilbert said:have almost 10,000 mi. for the last 1000 has had a slight fuel starvation at wot. at first thought it was the rev limiter, until I watched the tach. no problem up to like 7/8 throttle, just half the time at wot it starves enough to notice. the only filter I see is on the pump. anyone else experience this?

donuts are fine and have changed them before, were fine then too. just got back from 530 miles. definetly starving. either a kinked line or obstruction of some sort

interesting, came on tonite to see if anyone else has had this happen.. mine just started doing it at about 12,000 miles, I changed plugs, coils, fuel, has new donuts, still does it. it now has 13,000 miles and still bugs me as to what it is. feels like a hesitation under hard load about 3/4 to full throttle and just above 9k rpms. sounds like a misfire or stutter.. do these have rev limiters?

yes it has a rev limiter, but its 9300 or so. I will dive into it this spring and update. I figure if nothing else it may be the pump

What did you find out? I have a problem that is similar to this, just mine is happening at about 5000 rpm and is only doing it when warm, not bringing up any codes

not sure if this can help or is part of the problem ,but the stub shaft for the primary clutch ( part # 8GL-11406-00-00 SHAFT ASSY ) has a kind of a gear on the inside of this may become loose ,( this is also part of the "clutch" rattle we`ve learned to live with )
not sure what this gear all does but I believe it controls timing and pretty much tells the motor (ECU ?) what position the crankshaft is in.
