Here I am back so soon , just started the engine rebuild on my srx 600 and found the alloy bearings machined in the head and the rocker cover have had it , looks like it has been starved of oil , or a bit of crap got in ,and has picked up some metal on the one nearest the cog , anyone out there no where I can get a top end , been trying all over the place but no luck yet . or can it be repaired without costing the earth , any help would be appreciated many thanks ....nev
