Tidying up my "\Temp" folder, found this again. Taken from a Moto Guzzi motorbike forum -
I once spent several hours looking at a Honda that refused to start.
It was a favour to settle a family argument.
Father and son were not speaking.
Father was a Senior engineer for a high tech engine company.
Son was at college studying art.
Son had filled up Honda CB175 from cans in garage, bike ran for a while then refused to run again.
Highly skilled father had reduced the machine to parts and ended up putting it all back together with new gaskets.
Still no life.
Stupid here lifts the tank cap and sniffs, Diesel fuel.
Mummys range Rover was Diesel.
Empty tank out, drain carbs.
Fill with fresh petrol.
Two sets of eyes watching me.
The bloody thing turned over spat and kicked but refused to start.
I get the impression it's all my fault.
So I check the bleeding obvious.
Know-it-all engineer had put the leads to the coil on the wrong way round, sparks 180 degrees out.
Clean and gap points, check advance retard, swap wires.
Purred into life.
I think they are laughing about it now.
Second bike, same family.
Older brother.
MZ TS250
Running perfectly, I had just delivered it to him from the seller after road testing it.
Off boy wonder goes to some smelly hippy music festival in Somerset.
On the way back, bike karks it.
All my fault as I road tested it; it ran perfectly, had an owner who paid a motorcycle mechanic to maintain it and kept it clean.
Recovered machine in my works van.
Then the admission it was smoking heavily and he thinks the crank seal has failed and that's why the owner was selling it. Know-it-all father nodding head sagely.
I walk over to bench, pull out paperwork, receipt for exchange crank + new mains and oil seals 3k miles ago.
I ask idiot if he has altered anything.
Oh I topped up the gearbox oil .
Why ??
Well it was a bit low when I looked in the filler cap !!!!
On this bike you remove a screw and check for level, he removed the filler screw.
How did you top it up?
Oh I got a container and poured it in then I shook it several times until the bubbles all came out and filled it to the top.
FFS !!!!
I drained the gearbox. 3 times as much oil as specified!
Engine out, new seals, runs like a dream.
He is a highly skilled engineer now.
Working on aircraft design, luckily a long long way from me!
Yep some people need a restraining order signed by a judge to prevent them fiddling with vehicles
