FH - shaking down

 Well, the Huntmaster is back on the road and very lovely she is too. When I last rode her a couple of days ago I sensed that she wasn't starting quite as easily as normal and back in the workshop I had a look at the points - they were a little bit closed up and on adjusting them back to 12 thou, her usual immediate starting returned. I'd also weakened the idle a little bit and speeded up the tick over. 

Today she's back on form, going really well, starting very easily and on arrival at my destination showing no oil leaks other than a slight weep around the base gasket and the usual drip from the chain case.

Back at the workshop, I tightened up the base gasket and it occurred to me that maybe I could thicken up the felt pad in the oil tank to reduce the oil going to the chain case. 

Looking around the bike I noticed there was a slight weep from the oil feed to the inlet rocker box. 


It turned out that the acorn nut on the other side was very loose. 


What you have to do is slacken the banjo nut completely and then tighten the acorn nut such that the rocker shaft is tight against the inside of the rocker box and then when that's done tighten the banjo bolt.

I have some 3 mm felt sheet that I bought for the W/NG air filter - I'll see if I can roll up a bit of that into a cylinder of about 12 mm diameter and cram it into the Huntmaster oil tank chain case feed. Maybe I'll wait until I change the running-in oil (SAE30) to the normal oil (SAE40) - that might make a difference.

More later.
