So my son just traded his 250r for a 99 banshee today...rode it around a field for a bit and it ran good...wouldnt idle very well but started right up just had to give it some gas to keep it running. So my son took it down to the woods to ride it for a few after the guy left and 5 mins later he was calling me to come get him. Bike bogged down and stalled, and now the kickstart wont move. I drained the fluids and pulled the side cover. Everything looks fine in there from what i can tell. Pulled the plugs and they were dark but didnt look too bad. Need help on what to do next. Im laid off and my son is bummed but i dont have money to take it anywhere, going to have to do it ourselves. Where should i start, i have automotive experience but not atv's...
