my bro has his 98 cr250 and a spare motor(hint hint)lol if the ported blaster ever blows up he said i can have the spare cr250 motor to put in the blaster.but besides the point whats the best mix for those motors?
Quick google search for a honda cr forum shows the majority of the guys still run 32:1. My girlfriends brother in law rides a CR250 and he uses the same gas in his Banshee and his CR. He mixes at 32:1.
Engines are engines. The fuel doesnt know the brand. So, you jet based on your ratio, you dont set ratio based on your jetting.
honda cd bikes are recommended to run 32:1... pro honda hp2 is sold in pint bottles and is labed 32:1 premix designed for honda cr bikes... you can run what ever you would like but i have used the pro honda hp2 in my cr bikes and they all were very happy, same with my blasters and lt250r all ran on hp2
