Best upgrade I made to my 300ex was to trade it for a Banshee

Beta-cat.. you may have got something more powerful and faster, but there not as near as reliable.

Hey RidRedRider,

I agree totally, My ol' 300 was bullet proof. I actually lost the oil plug and didn't know it and it ran dry out in the bush. I managed to get a bolt from a buddy, fill it full of 2 stroke oil and ride it home. Then I got a new drain plug, changed the oil and I didn't have a hitch with it. The guy I sold it to is loving it.

The banshee is alot faster and has alot more power, but the relibility just isn't there.
