Re: Changing oil with an anti-draindown valve fitted
Sludge settles in the bottom of the oil tank so I mostly remove it and shake some Kero with roofing nuts in it to dislodge the sludge . Hose out with water under pressure and dry with a hair dryer. Purging the oil lines is much less important. Plain bearing motors need a good oil filter and cranksha...

Re: Balancing individual steel flywheels
Mauled up tapers do not wear evenly. and will often settle to a worse position in use which will cause strain on the cases and vibration as well as timing gear whine. Unless you're racing it the iron wheels will be fine cheaper and easier to get. The crankpin in them is tapered and the rod eye bush ...

Re: Balancing individual steel flywheels
Sorry to say so but that taper is a real mess I wouldn't re use the main shaft either and unless you are careful the shaft will go further into the taper and the nut will bottom on the thread.. BIG angst. Nev

Re: HS Replica
I think you'd be flat out getting a good alloy barrel.. The Velocette 500's went back to iron as did the 500 twin ARIELS. Just having a good alloy head will reduce detonation but they need a complete redesign with a shallower combustion chamber and a bigger inlet than exhaust valve and properly flow...

Re: HS Replica
Had some of those but I've got the ducks disease so thought I'd go the Bartram Ht5 way and it's 132 KGs. Thanks for the reply. Nev

Re: VHA liner installed
Maybe we should go the way Velocette did. Revert to the Cast iron barrel and steel push rod cover tubes for cooling and lightness and have the fifth stud for the 500's incorporated in a new pattern. If I was a bit younger I'd probably do it. The pattern is not that complicated. The Later 500cc twin ...
