Re: Ariel singles speed vs. ratio calculator

Yes I see the error in my ways would need to work out the K81 profile and put that dimension not the rim size in the spreadsheet also my tacho only goes to 8000 and vibration was something fierce so although the needle looked like it was around 8000 it could have been 7900 also the streamlining was ...

Re: Ariel singles speed vs. ratio calculator

My VCH with a 23 t primary and 18" rear wheel recorded 108 mph at 8000 RPM through the speed traps on conrod straight at Bathurst race track, maybe a little streamlining and Shell A running through a big GP carby and tuned length megaphone makes a difference to a factory machine? On the calcula...

Handlebar Liner

After a few years of searching for a second Handlebar liner I decided to make my own. Turned down some 32mm dia Aluminium bar, turned out the groove with a home made form tool, cut with slitting saw an finally parted off. The thickness of the web between the groove and the hole for the bar is only 0...

Re: Oil line position on VCH or alloy VH

Thanks Adrie, makes sense, I will run it over the rocker cover along the frame and in between the cylinder and the magneto then around to the outlet from the timing cover. Makes it clear now why none of the photos I have looked at show the pipe, it is cleverly hidden by the petrol tank and oil tank ...

Re: Oil line position on VCH or alloy VH

Re: Oil line position on VCH or alloy VH

Thanks Simon, I will take it around the back.. Drags supplied a length of zinc coated tube and either front or back of the engine it still looks dodgy as it descends down the barrel to the side of the spark plug or the rocker boxes. Maybe someone can take a photo from the the chaincase side that wil...

Re: Oil line position on VCH or alloy VH
