hello i am from saskachewan and am looking at getting a turbo pro rmk. i ride mostly at 1500 to 2500 elavation (90 percent of the time) and in the mountains 10 percent of the time. I would like to buy a used turbo pro with either a boondocker or silber turbo on it. with the low boost blow of valve actuater. i only have access to 91 octane pumpgas. how would i be for reliabilty and longivity? and is there anything i can do other than higher octane fuel?
