[TR] Valve train noise

[Bob]

Give http://triumphrescue.com/ a call or email. They did a wonderful job 
on my 3 engine awhile back. Located in PA. I am sure you could ship your 
rocker shaft to them and get a fast return.

If the noise is not from the rocker, maybe your chain tension-er is broken.
