Have a Honda 300trxfw 4x4
Carburetor is good.
I know this because I swapped it with a bike that is running good. My carb had no problems on my friends bike and ran great. And his carb in my bike, the same problems occured.
Coil is good.
At 1/4, 1/2 and 3/4 throttle when it reaches steady rpm it continuesly drops and raises rpm like if I were to be tapping the throttle
At wot it runs fine.
It did this before I snorkeled it. It did this before the gear reduction.
Im at a lost. My friend says timing chain?
Anything else u think it could be?
