Not being rude but I think that you answered your own question. Mine sits from Nov. to April or May every year. I try to start it up a few times during that period.
In my son's shop they buy power steering fluid and brake fluid in bulk, the bottles look the same. Someone put power steering fluid in the brake system in a older cadillac. The brakes worked for a day. Next day almost no brakes. They had to replace every brake part from the master through the wheel cylinders. Swelled the rubber parts. They lost some money on that mistake.
Wrong time of year. At least in the northern part of the country, most people don't want to spend $6,000 right before Christmas and let the bike sit there for 4 or 5 months.
1SDMF, just a little sensitive?
I would guess that you don't "flush the system" more than once a year, right? Removing the rear piece only takes a couple of minutes but moving the reservoir would take a lot more time than that. If you use T wrenches for the cowl bolts, it goes really fast.
I have had times like yours Joe. You know that you should stop working on them that day and do something else but you just have to beat it. You have to win. It is the simple easy stuff that really gets you, not the hard things. I'm glad you won.
