Exclamation Loud engine Click on firing

Help! I have a 99 VStar 1100. Was running on the highway and downshifted to pass a car, when I shifted up again I started to hear a very loud click sound in the rear jug on firing. Sound is there all the time, louder under a load, no so much at idle. Bike runs fine, and I am at a loss.

I am about to tear into it to try to ID and fix the problem, but have no idea what it might be. Valve? head gasket?

I have done lots of "easy" mods myself like carbs and hypercharger, but this will be my first time tearing down an engine this far.

Thanks!

"Click" usually means an out of adjustment valve, followed by a "Clank" that usually means the valve has impacted the piston, followed by the whooshing sound of air through your helmet.

I had an '82 Virago 750 that made the same noise when the exhaust valves were badly out of adjustment.

Get out the feeler gauge and get to it!

I'm guessing a blown head gasket. Maybe a loose exhaust pipe flange.

Next?

Cool

Compression test it and go from there, if it is valve contact when was the last time the valves where adjusted? How many miles? Remember loose valves make power, so set em up on the loose side.

Ken, did you not make sure the quantity you ordered was 'each' and not 'case'?

So you have, what, 23 cans to unload?

If it was a Harley it would be a clank or a thud, that would usually mean another part fell off

If you hear a loud "click" on firing, it usually means it's time to reload.
