I'm curious if the race book set-up for this sled is reasonably accurate. In particular, the 54-40 cam in the secondary and the 18 tooth top sprocket. My personal feeling is that race book specs are usually geared too low to work in the real world. I haven't worked with this small of a sled before and will have to buy some new parts, so I don't want to spend money on items that don't work. I know the 440F is underpowered but my daughter wants to try grass drags and my sled is too big to learn on. Buying red or green is not an option in this house so the old 440F will have to doo. Tips from anyone who has raced this sled before would be greatly appreciated. Thank You.
