I am actually asking this for a friend. We were doing food plots yesterday and he has a like new 650 Rincon, not sure what year but can find out if it makes a difference. We would drag a homeade harrow over the food plots to smooth them out and the bike would constantly overheat and we would have to wait a while for it to cool down and then start back up again. Also, the gas in the tank would start to boil and he has a vent gas cap and it was venting fine, but the gas would still boil. What can be done to solve this? I don't want to hear the radiator was dirty either because he keeps it immaculate and if a little dust on the radiator makes them run hot there is a design flaw somewhere. The bike is geared extremely high I've noticed and I have heard of a programer chip available for this bike. Would that help? Have also heard of Engine Ice. Would this make a big enough difference? If anyone has found a way to solve the problem please let me know. I realize this bike is suited more for trail riding but would like to find a way to make it more of a work horse without him having to sell it. Thanks.:frown:
