Okay so here's my dilemma. I have a 2001 GL1800. The bike has been very good to me. A lot of Oil and Tires. I love it . I have over 350,000 miles on this Beast and it's been all over the place . And whether I'm riding with a group or off on my own for a couple weeks I've always felt that I have something reliable with me that will get me home or to help. Just returned from a trip to glacier Nat Park and Yellowstone. and i was going to replace the rear shock. Surprise!! this is what i found. The bike has a cracked frame in two places . on the left side. Didn't check the other side yet. Yikes!!! Thought it was a little loose in the turns ;-) The frame has been repaired once before. I'm contemplating what to do. I can have it repaired again (Welded). Or Winter's coming and it would be a good time to just swap the frame out with another one. If I decide to do the swap. Do I look for a frame that is from an 01 to 03. Or do I go with a later frame 04 and on. The later frames supposedly has beefier welds etc . Is there any problem using a later frame on an earlier GL1800. I notice the PN: are slightly different.
