June 2020 - More misdeeds by Royal Yamaha Service
After sorting out all the misfits and missing parts by Royal Yamaha at time of drive shaft replacement, was going fine, but bike wasn't doing any mile since lock down 1.0. Had to got to wife's house, took my boy instead of Dio since there wasn't anything to haul. While waiting at signal, there was suffocating smell of burning oil and was looking at other two wheelers in vicinity to see who is the unfortunate one with blown engine. Next morning, while taking bike, there was pool of oil below and gave a shock.
Checked for the source and it was the drain bolt. That garage was infamous for ruining the threads in the engine. Feared mine had the same fate. On closer look, the crush washer was missing. 50:50 chance of thread damage.
Fresh drop 5 minutes after parking.
Then I saw the bolt half out. Immediately tightened up all the bolts. Could have paid more and transported the bike to regular mech than the crap shop.
I was doubtful about the oil from the beginning. He said it was Motul 3000, but I knew it was gold in color. This was silver. One of my friend stays across this garage, said some unbranded oil bought in barrel was used there. Bike clocked just 300 km since the work there and gear was super hard and bike was vibrating very much and there was smell of burning oil from exhaust. Checked the oil and it was murky green in color with a bad odor like mixed with coolant. Didn't want to take any more risk and wanted to change it then.
Another thing noticed was choke was not engaging and lever moving freely. Knowing this guy was allergic to choke, checked and as expected, the cable was disconnected.
Installed it back.
Bought new drain bolt with crush washer, in case there is damage in there.
