Re: Alaska preparation
Well, flushed the control circuits today and had an unpleasant surprise. The front master cylinder has gained enough drag so that the spring alone only slowly returns the piston. It works fine with pressure against it, but during the flush it was sluggish returning, mainly the last 1/4” or so of travel when it would almost snap back. Looks like the seals have swelled a little or there is some corrosion or gunk in the cylinder. I can’t believe it is gunk as the fluid looked almost new. At most a light amber color.
I decided to flush the clutch since I had all the stuff out and it also looked almost new. And the clutch seemed to have a little more drag than normal also. I suspect it is just the seals aging. I assume BMW sells rebuild kits, but I haven’t looked into that yet. I suspect my next flush will also include a master cylinder rebuild.
I started assembly and hit a snag putting the gas tank on. I had not used long enough hose on the fuel lines coming out of the tank so the QDs were too far rearward to mate with the ones on the bike. So, took the tank back off and have to do a little more fuel line work. It does look like things will be a little more congested with the clamps and such for the SS elbows. Looking back on it, I would probably just pay the money next time for the gold plated OEM lines. Not sure the effort required to use regular unformed fuel line is worth it.
And I forgot how much of a pain it was to install that blasted air box and tighten those clamps with no room to get hands or tools in there.
Well, got 5 days of travel and board meetings so get a few days “off” before getting back into the LT.
