2004 Sportsman 600 bogging at 1/2 throttle
Hey everyone, I've been researching this for days and can not for the life of me figure this one out. Thanks in advance.
2004 Sportsman 600, Not the Ducati coil and carbureted, 880 miles
Bike will start perfectly, idle and rev until 1/2 throttle where it starts to bog and spit. This happens both in park or under load.
I can maintain about 20-25 mph by feathering the throttle but anything above that and it starts sputtering.
So I did the following maintenance and repairs:
New spark plugs as the old ones were black so running rich
Cleaned carb
Did a Carb rebuild kit
Checked the emulsion tube / needle jet and seems fine at position 3
Diaphragm and slide looked good from what I could tell
Choke seems fine and not stuck open
New air filter
New air box to carb boot (it was split)
Float height is at 14mm
Jetted to 152.5 as I'm always at higher altitude, stock is 155
Tried with the air box removed and the same result as when its fully sealed up.
