  1. The bike specs say there is up to 130 mm of travel in the forks. Since the inside diameter of the forks is about 36 mm (or a radius of 18 mm), we must have at least of "air" inside of the forks to prevent hydraulic lock (aka, "hydro-lock"). So, with that in mind, the manual states the oil level in the forks should be 162 mm as measured with the forks fully compressed and no springs/spacers/washers inside. But, does that mean that all those components (spring, washer, spacer, plus fork cap!) really take up of space inside of the fork? This seems rather much, and I was also thinking of raising the fork oil level to get less nose-dive during braking (an effect similar perhaps to getting stiffer springs, for example). But, do all those components really take up 165 cc of space inside the forks? What's the highest fork oil level that the FZ-07 forks can safely (i.e., hydrolock-free) handle?
  2. Last Season I changed my fork springs to some by Sonic[.90] and changed over to 15w oil. Sonic included some pvc to make new spacers and by their instructions the preload seemed to equate to the fork cap sticking up about 16mm(0.5in). Over the winter I bought some preload adjusters[MCMoto] and wanted to know if I should cut down the original Yamaha 10mm like he states and then use the spacer or some other suggestion. To be honest Sonics instruction of about 16mm(pvc sticking out beyond the fork) makes the forks pretty stiff (I have not measured my riding sag/sag while on it I plan on doing it soon though). The preload adjusters seem to come with by their description "Initial Preload Adjustment begins at 10 mm past stock" and "Maximum Preload Adjustment finishes at 20mm past stock". So it doesn't make sense to me to cut the original spacer only 10mm because that would make it stock again. What do you guys think? I'm also kind of confused on why it is that Dave Moss states to cut the original spacer down, where spring manufactures want us to make longer/bigger ones.
