i have a 97 scrambler, and it has not ran right in 4 or 5 years. the original tiers look new, its that bad. anyways it keeps overheating and it has been in the shop 5 times but they say its fix and when i get it back it just overheats again. It started when the rings burnt up, so they replaced them and bored it out. Ever since then it has overheated. It has been so long sometimes i forget i even have a quad.

 

well first off welcome

Now when your engine gets hot, does your rad fan turn on... is your water pump bad? do you have enough coolant

 

also, since they bored it, its displacement is larger, did they rejet to larger jets to accomodate, is the machine running lean? do a plug check....

also, does it have a thermostat, I assume the scramblers are water cooled, replacement thermostat...
