Following on from our recent discussion about my oil system (1965 B40F), here is a photo of the gas tap which threads into the bottom of the tank (to solve the incontinence issue.) Also shown is the filter which sits on top of it. But I guess it's no good for it to be just sitting loose on the end of the tap when I screw the tap up into the tank. It looks like it might have been held in place with some kind of glue, but obviously it's come loose when I unscrewed the tap from the tank, so I guess that's not an ideal way to secure it? I think I'd like to continue with the gas tap method for now, rather than try to access the non-return valve, (though of course the external NRV suggested in the previous discussion might be worth trying). Any advice please on how I can continue with the gas tap method but also have a secure filter arrangement? Phil.
Further to my previous request for advice, just thinking about possible options: if I did away with the gas tap, and fitted the standard pipe, spigot and filter, how big a problem would the wet sumping be likely to be? Ie, if I started the bike regularly, would it be an issue (and how often would I need to start it?) Phil.
Having given this a bit of thought today, I reckon I'll do away with the gas tap, and use standard fittings. This will mean wet-sumping, but hopefully if I start the engine fairly regularly, so, say, every week or two in the winter, it won't be too bad. Fingers crossed anyway. One way to find out. Phil.
It wouldn't take much debris to block that filter then your engine would be toast anyway so id say it was pointless having it anyway . I took the gauze filter out of my gold star tank , but fitted a morgo canister filter , in my opinion it is pointless having a gauze filter in your oil tank as if it gets blocked there will be no oil going to the engine and it will be destroyed anyway .
I plan on using the standard filter, which I think is in a cylindrical shape, just inside the oil tank outlet. I'd have thought that a filter like that would allow oil to flow but at the same time might stop small pieces of debris from travelling round the engine where they might cause a problem? But then I know pretty much nothing really! Phil.
I'm in the process of fitting a spin on canister filter kit (same as the Norton Commando one) to my B40. The whole kit is about £20 And it seems to be a highly recommended mod.
