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.

I safely ran a 3 degree key on premium gas all last winter on the lake and trail, in various temp. ranges.

I would go with a 3 degree. It will give you good performance with some level of safety still available to cover variable like poor fuel, etc.

yeah, you should be able to run a 3 degree key no problem, i think anything after that you have to get the flywheel re-groved.

Thanks guys. I'll probably go with the 3* to be on the safe side. You never know when you might get some old fuel. Do efi's have more timing stock, is that why you don't see any, or very few with this much timing? Thanks again for the info.

why run more than 2 degrees in trails, & lakes, more timing will hurt your top end, on the long run ?? I would run 2.5 , .020 offset, my 2 cents.
