BSA Sloper 500 single

I am to resurrect my 1930 BSA sloper 500 which I have not ridden in a decade. When I dragged it out to it up again this year, I had concerns about the oil levels in the and the transmission. As a result, I have a of questions before I start to this old bike again.

1) The engine has a dip stick adjacent to the spout on the right hand of the engine. It is a very long marked with a 1 and a 2. There is not a indication of the full mark, and I am to recall whether the 2 means 2 low, and the 1 means 1 pint or whether 2 is low and 1 is full. Can you please the markings on the dip stick, and where the mark is?

2) Also, there is a with a fibre washer on the side of the engine casing the crank. I suspected that is a drain plug for the crankcase, but I opened it, only a small of oil ran out of it, despite the fact that the dip is still over the 1 mark, so I now that this drain is either clogged (I did fish a through there) or that it not communicate with the reservoir by the filler spout and dip stick on the side of the engine.

So, now I am confused. what did I drain out of this plug, and how and where do I replace lubricant, and how much do I add (is there a plug somewhere)?

3) There is a very small inlet that angles towards the rear, on the left of the engine, high above the that appears to have had a tab to lock a knurled wheel or (although my knob is missing). I that this is a device for the primary chain, but I am not certain this is for.

4) Could you provide a complete primer on all resevoirs and fill, level, and plugs and locations of each, for the and transmission on a 1930 BSA Sloper 500

5) I would also appreciate a for all appropriate fluids to use in each

6) Finally, there is a dial on a knurled knob on the right of the engine, close to the dip stick I suspect that this the amount of oil distributed to the crank but I would also appreciate a on how to set and adjust this meter as

7) Do you have any technical manuals, or manuals for this bike you could share with me, or a for me to acquire these manuals? I be happy to reimburse any costs with reproducing them if you (or else ) can assist.

I am really excited to ride old bike, so any and all advice that can be promptly is genuinely appreciated.

you so much.

a video clip of the bike. excuse the gear crunching as I had not yet the clutch!

1930 BSA Sloper 500 — YouTube

Thank you so for your prompt response, as I am so to finally ride this

I will try to take a photo or two to you when I am next out to my warehouse, but I do not one yet. I have sent you the voyage video in the meantime!

I made some progress I wrote these questions.

my inquiry has changed somewhat as

I have learned the following writing my original questions.

1) The appears to be marked 0, 1 2, so I suspect this references the number of that the crankcase is in need of. I found a full mark on the port, which appears to with the 0 mark on the dipstick, so I that I have solved issue.

2) The plug on the left side of the case is still confusing me. there are two plugs with washers beneath the crankshaft so I now suspect that the lower one is a plug and the upper one is a level However, I am confused as to what is by these plugs as it seems to be from the fill reservoir on the side of the engine for two reasons. a) The plug appears to be considerably on the case than the fill and dipstick full level, and b) why you need a level plug on an with a dipstick? In either what does this lubricate, and how do I fill it (through the plug?)

3) I believe that the (which is actually cast the engine case) and angled on the left side of the engine is a to adjust the amount of oil that is to the primary chain case, but I to me be missing the adjuster device as is no knob to turn, just the and a spring steel locking which I suspect is intended to against the knurled adjuster

4) I would still appreciate a on all lubrication cavities, fill, and drain locations, and recommendations of lubricants for each cavity, the primary chain, as I suspect the clutches are supposed to be wet, and I that non-hypoid is preferred for wet but I doubt that these available in 1930. I have told that a straight non 30 weight is suitable for this The primary chain case not appear to be leakproof, so I am now wondering if it is to be dry with only periodic form the oiler described as opposed to being submerged in an oil like more modern

5) I am now reasonably certian that the indicator on the right side the dipstick, is an oil pump adjuster for of the main bearings, but once I would like to confirm fact, and how to properly adjust it, so I do not damage the engine or bearings.

6) is also a plunger type on the right side of the engine pops out when the engine is I suspect that this is an for the rider to confirm that is adequate oil pressure. Please how this is used and how it is read.

the rider reset it during or would low oil pressure allow it to on its own?

7) I would be extremely if you could reproduce and send the to me.

8) proper clutch adjustment to gearbox grinding when first or second from

Thank you so much for your to help.

I also sent a request this morning regard to the serial number on a 1921 Monet Goyon Wheeled motorcycle. I cannot read the first digit, and thye bike was transferred to me a 6 as the first digit, it appears to be a g or other letter or dgit. Do you what letter or digit bikes typically had as the first on the serial number?

Thank you so for all of your help and advice. I appreciate it.

Kind regards,
