I was wondering if anyone has installed a Holtzman Tempaflow on their touring sleds. I heard that it can really improve your fuel economy by as much as 3-5 mpg or so since it compensates for temperature differences in jetting and it tends to offer better throttle response and allows for cleaner burn with less emmisions too. I heard that the base jetting is set for 20 below Farenhite and then it leans it out based on temperature. I have really been putting on the miles on the trails this year and I came across this on the internet and was wondering if they really work well? I may be getting about 10-12 mpg (if that) on the 1996 XLT Touring and about 14mpg or so on the 1996 440 fan cooled Touring 2up. Any good or bad expiriences with them?
