Hope you have better luck with your T'NT than I have had with mine. Nothing but motor trouble with my 340. I did hear that the 440's were a less troublesome motor. I have to rebuild my motor AGAIN this summer. I gotta get it right, if nothing else I'll drop a 440 in there. I love ridin that T'NT !!! If you have video of your T'NT feel free to throw it up here, I never get tired of watching and listening to the " SKUNK " T'NTThe rotax is music .... Nice 72 TNT just got a 72 tnt 440 this year.
