Wet Sumping

Spot on Tiglet, fire away with the answer, looking at the wall in the background it looks like you took the photo opposite Governors Dip, although I can't be sure.

 

Rob North frame IIRC.

To be honest I didn’t take the photo and now a days my hands are to shaky to even think about taking a photo

 

Hi Tiglet, Robin North who is known as "Rob" trained in engineering in Coventry, a very highly skilled welder and machinist working "freelance", he first got into frames by modifying a Manx Norton frame to make a sidecar racing outfit running a Triumph engine, fast forward and he was approached by Douge Hele (Triumph Experimental Department) in my humble opinion Mr Hele should have received a Knighthood for his services to Motorcycling, he passed away in 2001 an exceptionally talented man. Rob was given a Trident engine to build a frame, he used T45 this is carbon-manganese, seamless and certified for aviation. Frames for the Factory Triples were made in two forms the 1970 frame had the oil cooler inside the frame ahead of the cylinders, the 1971 type frame was lower and the oil cooler placed in the fairing nose, known as Lowboy and Highboy, he also made the yokes and hubs to suit disc brakes. Rob was always known to be his own "boss" , he received £145 a race frame. Rob also made a few semi official race frames for individual racers. Unfortunately for Rob a former business associate {Stuart Ashford} and shame on him, allocated the frame design rights to Boyer of Bromley, who then passed the rights to Norman Miles. Rob North emigrated to America in 1973 were he set up at National City in Southern California, he worked with Don Vesco the two stroke genius, he also made frames for the BMW F750 Racers. The Race Trident at the time clocked 164 MPH. The list of hugely talented engineers working in the experimental department is very humbling such people as Norman Hyde, Les Williams, Jack Shemans, Percy Tait, Bill Fanon, Bob Haines and many more. I could go on and on with bits of history. The frame however in the photograph is not a true Rob North frame but a Miles Engineering.

 

I know we’re going off the OP thread Iceman and yes I knew a fare bit of your post.

Funny how the old grey matter gets activated,,,,,I thought bloody hell it’s 50 years this year since the first Anglo American Match Races later to be called the Trans Atlantic Match Races. Although some of the triples we’re a little tired by the time they came to Oulton they still sounded good.
Following on I’ve just spent an hour looking for my race programme for that event and all to no avail

My trip down memory lane came to a holt

 

Or it could just be that you've overfilled the oil

 

Hi Tiglet like you I have very fond memories of Oulton Park, coincidently I was looking at some archive photographs I have taken from that era, these included Barry Sheene, Randy Mamola, Cork Ballington, Ron Haslam etc etc, I also came across one of Steve Tonkin (TT winner amongst other accolades) and e mailed him a copy, he is racing Dennis Pratt's Suzuki RG500, tragically it was this machine that ended Steve's racing career whist racing at the TT.

 

Great picture mate at Deers Leap.

I’ve always lived within about 5 miles of Oulton and the first race meeting I went to was 3rd August 1964 (Bank holiday Monday)still got that programme.
Used to go on push bike with a friend in those days, leave it behind the Egerton Arms pub and walk across the field opposite to sneak in opposite the start line

 

Or maybe the breather is too short...

 

Hi Guys / Gals, I just picked up a 1977 Bonneville T140v that has the wet sumping issue. After running for less 5 or 10 minutes in the garage it deposits >500ml into the sump. Based on this forum and others I have ordered a new Morgo oil pump and currently awaiting the parts to arrive. Is there something I should look at or do in the interim on the off chance it's not the pump? Curious whether the PRV (pressure release valve) could cause this too?
