Hi All,
Newbie here and this is my 1st time opening up a motorcyle cylinder head cover to do a valve clearance check and fixing the oil leak at the cover's rubber gasket. In the process one of my head cover bolt snapped broken into 2, with part of it's stud embedded inside the camshaft cap. I have since took out the camshaft cap and remove the broken stud and reinstalled everything back. There's few question I would like to ask.
1) Why the camshaft cap is not available as a spare part? Spartparts manual show its consider as cylinder head assembly. I can't seems to find part number just for the camshaft cap. (But camshaft is available as spare part. ) Aren't the turning of camshaft will soon wear out camshaft cap??
2) I torque the camshaft cap locking bolt to about 9nm only, afraid that I might broke another bolt. Will this cause the cap to loosen during high engine rev?
3) All my valve clearance are on the loose end. could these wear be due to engine oil weight i have been using? I had been using 15W-50 weight oil because I ride in 34-39 Celsius weather ( about 90-100 Fahrenheit) all the time. And on a hot day it could be 40 Celsius.
4) The tread on the camshaft cap have been damage abit, due to this, i have reduce the locking torque on the head cover. any risk other than leaky top or missing bolt?
5) For the 4 small connector wires at the back of the ignition coil, how do we identify which goes to where if we forgot to label them?
