No its just taken a hard hit on the hex area from a gutter or something from the previous owner. Ciao

Anyone out there have an Oil Filter cover in good shape they are willing to part with? I need one for my Daytona engine I'm putting together. Ciao

If you had Chuck you may have ended up here. I've see this race many times. Its very fast. https://www.odd-bike.com/2013/03/the-irving-vincent-anachronistic.html Ciao

Dunno. A Norvin used the repopped Vincent engine coupled to a Norton frame. It was affordable to ordinary mortals, but still expensive. Here in Australia Vincent engines were fairly cheap in the 60's. Lots were used in speedway outfits.The Norvin was an English late 60's early 70's creation in the main when old Norton wide line frames and Vincent engines were't worth a whole lot. Plenty of engineeringly talented rockers and cafe racers of the day put them together. I was chatting to a spectator at the Classic that was riding an old 850T3 same as my brothers in law rode back in the 80's. Yes 2 brothers in law each with an 850T, one a T and the other a T3. This guy has an old Vincent series C Rapide at home he inherited from his late father and also some other Vincent bits to build another bike. He was short of a crankcase half though but managed to pick up a battered second hand one for $3000au from an ex speedway outfit that needs plenty of work and machining if its going to be matched to the half he already has. Not cheap to join the Vincent world. Ciao

This one for mine.

In the pits and parking lot. A couple for the Norton boys Some people still ride them as opposed to worship them The classic Norvin. This one shows up every year. Rob North Rocket 111, Replica most likely American flat tracker? In style at the very least. For Sale apparently,in the bike public parking. Quite nice.

rich46's Guzzi. Spent some time talking to him in the pits and watching on the track. Didnt get the chance to photograph the man himself though. Bike and rider seemed to be going well. Aussi Guzzi. Short stroke engine, titanium valves looked fast. Another Aussi Guzzi racer. Beautifully prepared.

They are trying to remove the debris from the oil return before it gets back to the sump. Better than relying on the sump screen or having the rusty dust like particles go through the sump screen, scour the pump housing before being captured by the filter. Ciao

I tried that with my Daytona (same basic set up). It did not work out well, there was too much oil loss. I wanted it to work as I had issues with the spine frame leaking oil due to poor welding. So I wanted to be able to vent the motor to a catch can like a typical roadrace bike. It did not work out well due to the high amount of oil that was in the air being pumped out. I think it has the whole oil separator set up in the spine frame because it needs a way of separating out the oil from the air. Other big block Guzzi motors have also used a system that separates the oil from the air in a tank. You just need something of sufficient volume. You can also use a media like stainless steel wool to help. But you still have to provide a path for the oil to flow back into the sump. I actually like the Guzzi system, except when the frame is not welded properly and leaks / drips oil. Perhaps your results will be different. What you could use is a catch can type arrangement in the line thats designed to function as a gravity trap. Oil enters and leaves from the top of the can on its way back to the sump and all the contaminants have the time and space to settle to the bottom of the small receptacle where they can periodically be removed.

A one piece 270 degree crank would be fantastic. Its what all parallel twins need in reality. Ciao

Yes I understand that, just pointing out if you need new rods then steel is the superior way to go from an engineering perspective. Also the harsh reality is and not trying to be an ass about it is that you also can do without the oil pressure gauge if you eliminate the assembly errors. Ciao
