I have a '94 400L 4x4 2 stroke. It has run good for the past 10 years but am now experiencing some little bug-a-boos.

1. Started to be difficult to get into hi-gear. Seems like it idles faster and won't kick in. Low gear works fine but after riding a bit it won't shift (or is difficult to shift) into high or reverse.

2. Was riding the other weekend and the engine started to bog down like it was starving for gas. It would idle fine but giving it gas would make it sputter and die. I replaced the fuel line filter, cleaned the fuel line, cleaned out the tank and in tank fuel screens, put in new gas, checked the bowl and needle settings. It ran a bit better but then started doing it again.
