Hi all,

I have seen a smaller oil drain plug to the left of the engine oil drain plug ( this one is positioned horizontally, and close to the Oil filter) as you are looking at the engine oil drain plug, and I was wondering what is it for. Does anyone know? I don't have a picture to show you guys

Since you don't list you bike type in you profile it would help if you said which Burgman you are talking about, 650 or 400.

I am sorry, I was multitasking (posted this at work whilst dealing with an IT crisis). I have a 2007 Burgman 650.

I don't know of any bolts that screw in horizontally in that location. There is one that screws in vertically. I don't think it holds anything on. I could not find any reference to it in the service manual. It appears to just allow access to the oil gallery leading to the oil filter housing, possibly for cleaning when doing an overhaul. No reason to remove it when doing normal maintenance.

it's next to the Oil filter. could it be a drain hole to help drain the filter itself?

I think that is the same bolt I am talking about. Maybe we have a different concept of horizontal and vertical. When I say vertical I am referring to the direction of the hole the bolt screws into. The head of the bolt would be facing the ground. It would be bolt #25 on this fiche. http://www.partshark.com/fiche_sect...ory=Scooters&make=SUZUKI&year=2006&fveh=10159

If you removed it you probably could drain the oil from the filter but you would get no more oil out than you would by just removing the filter. I generally follow the rule that if I can't get any guidance on what a bolt does I don't mess with it.

Just a guess, but it could be a casting plug. When an oil line takes a turn inside the case, the factory drills out one of the lines and then caps the end.

These the only plug that need for remove when do oil change.

No other require remove.

Just thinking it's the place to screw in an adaptor to check the oil pressure with an external gauge. I haven't had to do that on a 650 so could be wrong but that's my guess.

Yep I was reading the service manual this morning and you're right, that's where the oil pressure gauge connects.

Which section and page of the manual is that.

Check section 2, "Periodic Maintenance" on page 2-31. Nice photo there.

Thanks, looked all through the engine section but didn't think to look for it there.
