TT600R - loud ticking noice from cilinder head
A few days ago i posted a question for adjusting my decompression cable, i seemed a bit too loose and i wanted to adjust this. I noticed this while i was checking the valve clearance.
My TT600R is from 2003 and has done about 45000km in the last 8.5 months down form Alaska.
Well. about the valve clearance: Both right -side (exhaust side) exhaust AND inlet valve were without any play. I adjusted that and after starting it (difficult, as for a while now) there was a severe "ticking" sound. Normally you hear the valves ratling a bit but this was new to me.
After let it cool down i rechecked the valve clearance (outlet 0.15mm, inlet 0.08) which is well withing spec.
This morning i started it again and the loud ticking is still there...
So, what can be the problem? Which checks can i perform to diagnose the problem? Do i face a top end rebuild? Oil consumption is about 1ltr on 3000 km. I rode with other bike travelers a week ago and i didn't got complaints about smoking, except when engine is cold and using the choke.
Am in Copán, Honduras. Not many services around here. Nice place to hang around though.
Any tips/advise etc. are welcome!
cheers,
sander
