Te449 Timing Chain Slack

When re-assembling the cam shafts on my '13 te449, there is a considerable amount of slack on the timing chain even with the chain tensioner installed. Before disassembly of the top-end, it was very tight, so I don't think this is a worn chain on a 5k mi bike issue. I checked that the chain is still on the crankshaft sprocket and is sliding against the slider rails correctly. The tensioner piston is in the default fully extended position. Totally scratching my head...

Appreciate any thoughts you might have.

Thanks,

Hard to give a solution without having the engine here. Its not a worn chain so dont bother about that. Have you had the tensioner apart?

Thank you for your response Soderberg and I totally understand the challenge of troubleshooting over the net. I ended up figuring out the problem and I'm a bit embarassed to admit it. When I took the head and cylinder off, I must've let the timing chain slip enough that it came off the crankshaft gear, which explains the extra slack. Looking down from the head with a flashlight, it appeared to be wrapped properly around the gear. This is the first time I've ever looked inside an engine little alone take one apart. It is now back together with the proper tension on the timing chain. Thanks again.
