Thanks to everyone. Lucky Phil is correct. It is not a dry sump engine. It is a breather box. Blow by and vapors go into the box via the lower hose (front cover) ... any liquids hit a baffle in the box and return to the crankcase. The fumes/vapors go out the upper hose to the frame and fed to the throttle bodies. The frame on this bike IS the intake. I haven't heard back from GB yet but i am completely confident that this is correct. It is an odd machine and I just wanted to make sure I wasn't missing anything. In the good old days we would just run a hose out to the chain for some extra oil. Or onto the road like the Batmobile. Thanks to everyone for their input. Problem solved. Best, Pete

Yes it is the 1064 engine though factory modified slightly, balanced,etc but the same. The oil tank is a small aluminum box mounted on the right side of the frame, high up tucked under the fuel tank. Upper hose goes to frame and lower hose to the front cover. Please bear with me as this is the first MG I have worked on and like all euro bikes they have their quirks. I have looked for these answers but some are illusive. 1) When refilling the sump with fresh oil...do you add any to the oil tank? 2) is it true that you check the oil level with the dipstick screwed all of the way in? P.S. I wish all of the bike manufacturers would just agree if it needs to be seated or screwed in!! 3) Like many dry sump bikes that have been sitting for a long time, the oil tank is empty. Plenty in the crankcase. Should I add oil to the tank before running it? I want it warm to change the oil. 4) On that same subject, if you only fill the crankcase on oil change, how does the tank find its level? Does it just fill itself ? There are no marks on the tank at all. How full does it want to be? 5) Don't want to open a can of worms but I hear horror stories about oil filters coming loose. Some say to use the hose clamp concept, what do you think? P.S. If this is such an issue and could ruin a fancy, expensive motor... Why has nobody made a filter with a safety wire hole in it? Every critical fastener on race bikes are safety wired... Makes 'em safe! And you don't have to worry about them!! As I have said , there is very little literature on this bike so I just want to be thorough. It is a flawless bike with very low miles and I want to take care of it with kidd gloves. Thank you very much!

Thank you!!! Now I know. One more question if I may.... Do the other spine framed bikes have a dry sump like this one? Thanks again. Very helpful.

Thanks for the replies. Not concerned except that it is a special bike that deserves my best care. Is it typical to leave a little oil in the cooler? If so, no problem. It just seemed strange that there is no drain for it. The air idea would work too. Do most race type guzzis have coolers like this? Do you drain them ? I know it is a lot of questions but I really appreciate your input. Thank you!!

Hello all, I am new here. Working on a Ghezzi Brian SuperTwin. I would like to know if there is a technique to drain the oil cooler when changing the oil It is mounted high up and the feed/return lines are at the top of the cooler. It is a dry sump and the tank will drain via gravity but the cooler won't. I was thinking that I could hang the entire bike upside down from a tree and shake it? Is that wrong? Many thanks for advise
