Talked to a couple of other busa owners and they seem to think its the ecu
Instead of wasting time talking and guessing with other gearheads,go get yer hands dirty. Start with the least expensive and work yer way up. Half these tests are free to do. If you thinks its a fuel prob,get on it. Ecu,get on it. Talking to the gearheads at work is fine and all,but unless they are gonna come over and fix it,yer wasting yer time. It may be a simple as some shid gas,but the keyboard in front of you isn't gonna magically fix it for ya.
I'd get a siphon hose and drain the tank into a WHITE plastic bucket,then you can see whats foating around easier.(plastic syphon hose pump, 5 bucks)
Toss about 1 gallon of that gas into a clear jug.Gas rises to the top,water sinks to the bottom.(I got 10% water once at a fill up)
Shine a flashlite into tank and look for debris.
Test the pump or move on.
Lift the tank. 2 bolts at the front.lift slowly looking for a kinked line.
Use the prop stick to hold tank up.You'll fine it under the hump/pillion seat in cargo area on the clutch side sitting in pinch points.
Remove the pump,being carefull not to wreck anything like seals etc.
Get the filter out and clean it. Pour good gas thru it backwards,its called back flushing.Same as an' air cleaner.Never blow compressed air into it,always out.
How much shi7 came out of the filter? Lots,that might be yer prob. Nothing? Move on.
If it was dirty,re-assemble and go for a ride.if its better,but maybe not perfect,prob solved.(dont dump the dirty gas back in yer tank unless its minty clean.)
Bike is still fugged? and "The Gearheads" have suggest ECU.Find a busa buddy and swap a known working one in.
Go get yer hands dirty and spend 5 bucks. You'll learn alot as you go,and can maybe avoid big shop bills in the future.
