Can anyone advise please?
I bought my tr1 few weeks back and began to investigate the source of the many rattly noises from the top end.  Valve clearance seems ok- I have followed the instructions in manual, but should the specified clearance become greater as the camshaft rotates past the timing marks?
I removed the camshaft tensioners to find the ratchet mechanism past the end of it's travel - is it possible for the chains to have stretched to this degree?   Removing the cam sprocket covers the chains seem to be quite slack.
The engine spits and bangs when I close the throttle, and when I hit 5000rpm the power dies - carb sync?
The inlet manifold stubs seem to be slightly perished - tiny bubbles are visible with soapy water.   Could this cause a weak mix and the misfire?
The exhaust note on one side is quite smooth, whilst the other gives a pronounced "thump"
On the subject of starter problems, my bike appears to be fitted with a Lucas, UK manufactured, solenoid which doesn't seem original Yamaha.
If anyone is interested I can get more info on this as a route to curing what seem to be common starting problems.
Thanks guys
