I did a search and found that carb sleds seem to be able to handle more timing than efi's. Some posts say they were running 4-7* on the carb and 2-2.5* on efi's, there's not much about timing for carb sleds. I have an 05 F-7 carb and want to put a key in it but I'm not sure how much I can safely go. I always run premium gas. I'm an aggressive trail rider and love to go wide open on the lakes and I don't want to hurt anything. Thanks in advance.
