Anyone out there that can tell me what would be a good gas to oil mix ratio for it. I just bought this trike for 850 and the guy told me that he has been running 30 to 1. it seems to be smoking more than i think it should be. he said that was a little more lean than was recommended for it. what do you think? also, what kind of coolant, how much, and is there a special mix or ratio for the coolant? It runs great but i think it would run better if it was correct. thanks!!
