I'll be riding in the Lake Elsinore Grand Prix in November. An eight mile or so loop done over and over for 100 miles. I have a stock FC450 and I have no idea what the fuel range is. Has anyone actually tested this or have some info? I would really not want to make more than one pit stop, none preferably. If this is a problem, do you have any info on where I might get a larger tank for that bike? Finally, the seat on that thing is hardly sufficient for that type of ride. Does anyone make a replacement seat that's better than that slice of foam that comes on the bike? Thanks a ton in advance!
