1500 valve chatter

Post by vcdc »



I bought my 95 Wing in May 1995. It now has 237K+ miles. For about the last 10,000 miles the valve ticking has been getting steadily worse. Listening with a stethoscope, I found that the ticking noise is only coming from the left bank of cylinders. I had found a bad vacuum tube by the middle cylinder left bank, which I replaced. The ticking went away for like a few thousand miles but now the ticking is back again. I have always kept a strict maintenance schedule with this machine. It is now on it's 3rd timing belt with 57,000 miles. Can the valve ticking be caused by a vacuum leak some where? A stretched timing belt? I hate to give up an this motorcycle, but is it toast?

It could be another vacuum tube or the Cam belt/tensioner. Did you change the tensioner when you replaced the Cam belt? There's a great video on YouTube from Delboy's Garage that goes step by step through the process

I hope someone with more experience than me chime's in with a possible cause and solution.

Yes, I did change out the tensioners at last belt change, 57 K / 5 years ago. That does make sense if the tensioner is failing could cause the ticking. Starting the belt change this afternoon.

Let us know how things go when finished. Good luck. 👍


I'm not so sure about an inner child, but I have an inner idiot that surfaces every now and then.. :mrgreen:
