Tried the 'Grambo' trick

Greetings to all.

I finally got my VN a couple of weeks ago, (US import apparently from 'The Montgomeryville Cycle Center'), 12300 miles on the clock, Jardine fishtail pipes, missing tool box cover and a host of little problems (which I shall enjoy correcting), and have done all that has been suggested by one and all when getting one. You know silicone on the swing arm caps etc. One thing that had been bugging me was a ticking noise coming from the front cylinder

Anyway, I decided that this could be the ACCT and proceeded to carry out the ‘Grambo’ trick. It didn’t make any difference, so I’d thought I’d try it with the engine running. There it was, idling away merrily and I undid the little bolt on the end of the ACCT. As I did, the ticking stopped! So, I tightened it back up again, and it came back! I did this several times, just to make sure that my drug fuelled hippy days weren’t flashing back, but every time I repeated it, the same thing happened.

When I took the bolt right out, I noticed that the end of it wasn’t square and ended with a slight point to it. I figured that when the bolt was fully tightened, this little point was going into the end of the screw slot on the plunger and slackening it off, allowing the cam chain have more free play, hence the noise.

So I used my small angle grinder to take off the little point and made the end of the bolt square. I did this without getting down to the threads I might add, perhaps a total of 0.5-1.5 mm. Put the bolt back in, tightened it up and all was well.

Has anyone else come up against this?


PS I tried to use a copper washer on the bolt first but it wouldn’t let the bolt go in far enough to tighten up
