Been running it in street bikes for quite awhile with no issues other than the fact that they seem to run poorly
while the stuff is in the tank. If I were lacking the skill/time
to pull the carbs/injectors/fuel pump down, I don't think I would have many reservations about running it in a sled -as long as I didn't have any long, wide open runs planned while it's in use (until the next fill up). It has cleared up some problems in the bikes, but I'd like to note that some of the jets used on the bikes are much, much smaller than what you are likely to see on a sled.
Just my 2c
