Just got the bike back on the road after fitting new cams and followers did about 40 miles and removed the timing cover to check the seal on the rubbers and that everything was still OK.
Out of curiosity something I did not check when the bike was in bits were the oil feeds though the spindles.
I used a bit of 1mm copper wire to poke down the holes and found the cam spindles OK and the front cylinder through to the crankcase. The oil feed to the rear cylinder seemed to be blocked as the wire would only go in about 40mm. I thought it may be sludge but found it difficult to clean, I even put a small drill down and it was solid. I am starting to think it may have not been drilled properly or someone broke a drill down it.
I am guessing that this has been there all the time since rebuild about 9k miles ago. When I had the top end off there was a little sign of wear on the rear of both pistons but no pick up or seizure.
The question being is how critical is it to have the oil feed to the rear cylinder wall, my current thoughts are to run the bike as is this summer and maybe replace the spindle over the winter .
Any views welcome
