Dont' quit get your reply, but I'm assuming you think I'm "nit picking" the bike. I've had alot of cycles, and have never seen this happen on any of them. I always get alittle concerned when potential contamination of the fuel system is possible. Take a look at your Busa's fuel cap and see what I mean. The white residue is very fine, and some can be wiped off. I'm trying to determine if its just the rubber reaction to fuel in general, or maybe its the brand of fuel thats causing this. Hey, granted its not something to be too concerned about -- like snapping subrames or engines locking up at 160 mph due to camchain tensioner failure -- but its somehting that looks out of place.
