Well, I got some nice Tygon tubing and replaced the cracked lines from and to the tank and separator. It took a little struggle routing the lines away from hot areas and then getting everything attached...fingers are too large, but we got that part done.
Went to reattach the cooling system expansion tank and discovered that I could not get it into place...also, the line coming out of the top of the expansion tank next to the fill spout appeared to have become detached from wherever it was attached to...my recollection is that that is a drain line which is routed to dump overflow onto the ground under the bike...does that sound right? If so, I can't seem to route it properly, as it impinges on the rear cylinder as it loops over and down and I know that's not right. If it's not a drain line, where does it attach? If it is a drain line, how is it routed?
Also, what's the trick to getting the expansion tank into proper orientation so I can bolt it up?
You all have been very helpful and I'm learning a bunch...Thanks in advance for your assistance!!
