I knew four valves per cylinder wasn’t a new idea, but having it in 1937 was a revelation when cars had flathead engines. I bet early hot rodders were taking these heads, porting and polishing them and sticking them on Austin 7s or Ford 8HP engines.
I can't believe I have only just found this , great to see that you are making some videos. Keep them coming. I want to carry on with my 37 Special engine overhaul. I read your valuable remedies but would appreciate some more videos too. Keep it up please if you can. Thanks for your help
Ever since I got into classic British bikes many years ago I've been an avid admirer of the Rudge Ulster. I've now been actively looking for one for a few years and at last one has become available, a tidy 1939 model with the alloy head.. I have been to look at the bike and all seems well, except a slight crack at the front of the inner primary chaincase. This seems minimal and could probably be resolved by a careful professional welder but before I went ahead and bought the bike I thought I'd look online to see if I could obtain an undamaged replacement instead. After a long trawl I could only find two sets available and strangely BOTH sets had welded repairs in almost exactly the same location as the crack in the bike's inner primary chaincase (one of these had obviously been pretty catastrophic..) Is this a known problem with the Ulster and/or Rudges in general ?..
I take it that these are the "semi-radial" heads with parallel inlet valves and radial exhaust valves. I believe that Rudge also did a full radial head and perhaps a full parallel head. I am interested in the full radial head, can you point me in the right direction to find information on this variant? I am interested in the rocker gear which I assume had six rockers although I have seen a suggestion that there were 8 rockers.
Hi yes these are semi radial. Rudges started with 4V parallel heads in 1924 with the first fully radial heads in 1930 for the works teams. Rudges moved from fully radial to semi radial in latter years due to the complexity and minimal advantage of the fully radial arrangement. There were only ever 6 rockers in the fully radial set up. Further information including overhaul information on both semi and fully radial heads can be found on my free web site www.rudge-whitworth.com

Hi Rudge Whitworth went to 4 valves in 1924 and produced 4 valve engines until their demise in 1939

Interesting video. I am trying to locate my late fathers 1937 Rudge Ulster Reg HV7825 in a view to possible buy. Many thanks for the video.
Hi thanks for the compliment. HV7825 exists on the DVLA database with a last change of log book in 2005 - so the bike is out there and has survived.
@@rudgewhitworthremedies5399 Yes waiting to hear back from the owners club, also written to the DVLA. Fingers crossed.
