TRX70 bogging down
I just bought an 86 trx 70 for my daughter and it doesnt run very well. It starts and drives but if I get somewhat aggressive with the throttle, it boggs down and dies. I replaced the carb with new and still runs the same way. I replaced the plug, checked for exhaust leaks, replaced the fuel lines and still the same thing. any suggestions?

some bikes have a rubber boot that connects the carb to the engine. they can get a hair line crack that you cant see. you might try taking it off and squeezing it to see a crack. also if you have a oiled air filter it might have to much oil on it. the first time i cleaned my sons crf50 air filter i put to much oil on it, and it did the same thing. i recleaned it and it worked fine.

I have the same ATV for my son, and had the exact same problem. I got mine dialed in by the correct combination of the pilot screw and needle jet. The manual calls for the pilot to be 1 3/4 turns out and the needle in the 4th groove, but. that didn't seem quite right (I do live at 6000 ft. altitude). I can't remember what I set the pilot screw at, but I put the needle in the 3rd groove.
