Timing on a GL1500 Goldwing - help

Postby vtfarma » Mon Apr 19, 2010 4:23 pm



We did the timing on our 1988 Honda Goldwing GL 1500. We had the repair manual, followed everything through and it would not start. We took it all back apart and redid it. When we started it this time it idles fine but seems to pop when you give it gas. the lines all line up. Everything seems to be where it should be. Do you think it jumped, and have we damaged anything?

It idles fine but pops at about 3500 rpms. To rule out engine damage should we do a compression check on it before we do anything else?

Perhaps you accidently disconnected a vacuum line somewhere? There's a couple of them on the left side of the bike, above the valve cover.

If it "pops" when you close the throttle (at 3,500 rpm) then it's probably a disconnected vacuum line.

Personally, for a bike of that age (1988) I'd replace all the vacuum lines as soon as you diagnose this problem... They're probably starting to crack by now, and you'll likely further encounter this issue. Just buy a 30ft length of vacuum tubing from any auto parts store, and start replacing all the lines until you find the problem one... This way you'll both diagnose the potential vacuum problem, and simultaneously do this necessary maintenance item at the same time. As you diagnose, look not just for a broken line, but also for a Pinched one... In particular, there's one on the left side (above valve cover) that has a 180-deg bend in it, which can easily pinch.

Okay, that's today's project once he is back from his calls. I was just looking at it and it does look like one is kinked. Thanks a bunch.
