i was lucky, the silencer came with the bike and cleaned up ok, the headers i took a risk and got them from america, they were reasonable price but postage and customs charges added a lot. thankfully was in good nick so worth it.

well this project has been on hold mainly due to lockdown, as i am a self employed driving instructor had no income except the government handouts. Back at work now so returned to sorting the cylinder head. As a stopgap measure i had got another head but turned out not good so have taken my original head to Trigger to have the exhaust guides fitted and valve seats recut. Meanwhile i am looking at the seat which is solid with no big rips but looks a bit tatty on the lower edge due to the chrome trim being missing. It is not a U shaped rubber mounted item like the 500/ early 550 but is mounted onto the seat with little pins and clips. I can fabricate some mountings but the trims are missing and not available as separate items so a bit of lateral thinking was needed. I remembered that old 1960s Jags had a similar trim on their bodywork so got a piece off ebay, ( was actually off a daimler limo!) and will attempt to fit it. Main problem is i need to bend it slightly without kinking it so a bit more head scratching.

So fetched the rebuilt head from Graham a few weeks ago, he was good enough to build it up ready to fit so went on easily. When i started it up after rebuild it did seem to smoke so today i took it out for a ride. It is running fine, pulls away with no flat spots and revs as it should although not going mad as running in after its rebore. Result is no smoke! I am back on lockdown for a few weeks so might have a sneaky ride or two although i am a fair weather rider only! today was ok but a bit cold so hope it stays fine.

have been chasing an oil leak from the cam end bolt area which seems to be a common fault with the 500/550. I had replaced the sealing washers but still leaked so checked out the l shaped  bracket that hods the end cap on. This proved to be bent and misshapen so replaced it with a spare i had. not now leaking but for good measure i am doing a modification which Trigger uses to make sure it stays oil tight. Have been out a couple of times when it has been a bit milder and running well, handles great and sounds great.

What’s the modification? I’m rebuilding my top end over the winter.

instead of using the lower washer use a o ring, a countersink is needed in the cam cover to receive it, Nurse Julie can supply the parts required and Trigger can give you the expert knowledge.
