Hello everyone!
I am in a real need to find a good mechanic because I just had a pretty bad experience, by following Google's "expertise"... so I am hoping that one of you maybe you could guide me better based on your experience.
Just to give you a little bit of a background story. I purchased a used FZ6 Fazer (2006) in July with around 30.000 mileage. It was very well maintained by the previous owner and since then I travelled almost all Europe and 12 countries. Everything looked fine. When I came back in London and I started using it to commute to work it started to behave a bit strange when the engine was off after a small trip, and I was trying to start it again. It wouldn't start straight away.
Basically the problem got worse in 2 weeks time when the engine wouldn't start. The bike was giving me the error with number 12. With a quick search the problem seemed to be the crankshaft position sensor, which is not a big deal. It is an electrical problem and not mechanical. Yamaha dealership wouldn't accept to get it fixed since it is more than 7 years old, which I still find very strange, and even rude but that is another story. Since I couldn't start it I looked if a garage was nearby, and actually there was. When I called the guy he told me that he is not my area anymore and that he moved. But since we had a good discussion and he looked knowledgable I decided to hire a van, get some friends with me and get it to him. He was very confident that will be a quick fix. 2 days later he called me and he said that is a much bigger job since "the timing is out camchain has jumped a tooth on camshaft sprocket"
I told him to hold and that I would come over to check, cause some of the things did not make sense... 2 more weeks passed, (while the bike was out in the rain uncovered) and I went there I realised that he based his above diagnosis without even opening the engine...! Long story short he told me that he would open it and check. Almost a month is now passed... And yesterday he calls me and basically he gives me the following report...
"
Engine does not start
Firstly fuel pump, fuel pressure and injectors were checked
I suspected cam chain tensioner failure causing the timing chain to jump a tooth on the sprockets
Checked timing it was all ok, my initial diagnosis was wrong
Checked ignition coils and crank shaft position sensor
Sparks but after inspecting the actual spark plugs they were showing signs of overusage furthermore the spark was a thin light brown colour
Spark plugs were replaced but no improvement
Further investigation was required
Noticed petrol in the crank case
I suspect it is caused by low compression
Valve clearance needs to be checked as not fully closing valves are a very highly probable cause
Chances are low but also worth mentioning that worn piston rings are also not an unlikely cause of the low compression
These are purely speculations or educated guesses at best
Recommendation is to strip top end check valve clearances replace valve shims accordingly reassamble check compression if no little or no improvement replace piston rings"
As you can imagine I did not receive the service I would expect, and basically he told me that it is not worth doing the repair... but the bike overall behaved perfect apart from this, so I would not trust that it is not repairable...
So, could you recommend someone that you would trust to do a good job? I would extremely appreciate that!
Thanks in advance!!
