Working on 3 cylinders

[Slaninar]

So, this spring my Fazer started working on three cylinders only. The leftmost one gave up the ghost - even though it's parked on centre stand.


What I've done so far:


- Checked to see if the plugs are throwing sparks. They are. Replaced with the new ones just in case.
- Cleaned the carbs.
- Checked the compression - the problematic cylinder has lower compression compared to the other ones.


Carb. intake rubbers are leaking - at least the leftomst one definitely is.


What I haven't done:


- Checked the carburator membranes.
- Checked the valves.


To make the matters more interesting, local mechanics aren't interested in the job.
I get told to bring it in during the winter, and to expect at least a $1,000 bill for the repairs.


So, I am seriously considering to give it a try myself, and see where it takes me.
Sure, this season of riding seems toast already, regardless of what I do, but with a bit of luck, I might live to see the next spring.  LOL


I can source parts from Serbian Yamaha dealer (uber-expensive and months waiting, but it's not impossible).
I can also source stuff from German Amazon, and perhaps from some German online stores (not all of them will take Serbian Visa debit card payments with a German delivery address).


Any tips or advice are welcome.
The advice from the last mechanic I talked to was to sell the bike and get a newer model.
