i have a 170 main i use for summer riding should i rejet for the winter?

 

Yes, you should rejet when the temperatures drop. Cooler temps can make your quad run lean. If your bike starts to backfire out the carb thats a sign of running lean. I will have to rejet my DS as soon as the temperatures start to drop.
