I have a old 81 DR 500 and I love it! I live on Vancouver Island, BC. There is lots of hill cimbing......
Recently I have developed a strange shifting issue. If the bike is in 1st, then i can get 2nd. But if shift into 3rd, I am now stuck with only 2nd and 3rd. I can't go back to first. If I upshift to 4th, then I'm stuck in 3rd and 4th and cannot go back down to 2nd.
I do get back down, intermitently, eventually. But it's not there when I want it.
Basically I get a 2 gear range out of 5 at any one time. So to finish my last ride just kept in the 2nd and 3rd gear range to get home. If I upshift, I'm stuck.
I hope I've explained this ok. Thanks in advance.
