Ticking on engine startup, goes away when warm but audible @ 4000-6000rpm
Im getting a tick on startup, goes away after a minute or two. Similar ticking occurs between 4000-6000 rpm, kinda like before I had the Krieger cam chain tensioner, but not as loud
I've tried fine-tuning the adjuster, and there is no tick at idle once it's warm, just after the first start of the day.
Bike just hit 10,000km- noise started in the last 500km
Loose cam chain? Valves?

loose cam chain would be noisey all the time?
I'm trying to troubleshoot a technical issue...And no one has an opinion on the matter? I wish I could post something that gets replies like a ride report or a question about vapor displays but until then it would be nice to get some friendly advice before I have a catastrophic failure

Its interesting that it goes away when it warms up??? Ive noticed some noise which i believe is the cam chain. while riding about a week ago I noticed the rattling noise getting louder...I was about to pull over to check the oil level...when I herd and felt a dull bang through the left side peg. The rattling noise was insantly gone!!
After reading many post about the auto cam chain tensioner, I believe this is my problem. I see you have the manual one maybe some more fiddling will fix it. I agree with ahnh check the cam chain and valve adjustment. Good luck!!

IIRC, Krieger has said that when properly adjusted, or maybe a little on the lose end, it's normal to hear a little cam chain when cold but should go away as it warms and things expand.
Mike - I think OP has Krieger manual tensioner so can't be auto one.
ahnh - Agree. Check valves, and not only check to see that the cam chain is on correctly and everything timed right, but also check the cam chain for elongation. I think TNC had a problem where is auto tensioner wasn't working properly for long enough that the cam chain stretched and caused problems. There's a spec in the shop manual for chain length.

You can also either reset the tensioner cold to make sure it isn't some play in the cam drive. If you don't have instructions hit my website, they're there, or call me Krieger Cam Chain Tensioners
But before anything else, listen carefully when you start the bike up. Where exactly is the sound coming from. If you have a mechanic's stethoscope or even a long handle screwdriver putting the tip around on the tensioner, then the cam cover in various places to find where the noise is loudest. I have two valves .001" out of spec on my Zephyr and with a mechanic's stethoscope I can locate them easily with this method.

Krieger you are a paragon
When you say reset the tension cold do you mean as done initially when installing the manual tensioner? Or make the fine adjustment (finger tighten) when bike is cold..
Thanks
