I have similar problems. My Honda trx 420 starts great and runs until it gets warm (hot). Then it runs at an idle but when I try to throttle up it bogs out. If I shut it off and let it cool down (maybe 5 minutes) it will start and run great. May run 1/2 an hour at 60 degrees and moving at 15 mph. We have cleaned air filter, changed the oil, washed entire machine especially the CDI unit. Any suggestions?
