Hi Caulky,

Help you decide here's my thoughts:

Mine (A65) are fitted on the return, because the supplier said so, no problems so far. Normally a pressure differential indicator or bypass system is used for filters in the suction side. The best position is directly after the oil pump if that's possible.

Be aware some filters have a inbuilt non-return, an over pressure (bypass) system and will need careful installation for obvious reasons.

An air to oil cooler, the  cooler will only work when air is passing through the fins, so there's a need to be moving at speed. That's why they are normally fitted in front of the water radiator in the fan air stream.

Best wishes...

Hi hubcap,
                   He may have knowledge or be concerned with the use of modern ethanol based fuels.  Amal have worked to provide components resistant to them, this maybe worth a read:

I had to buy new carbs, my project never had them in the first place, so I opted for the Premier specification which resists the ethanol effects. You may consider whether you want the expense of replacing/rebuilding them or continue with what you have until there is an issue.

Electronic ignition is a better option. That may provoke many comments, but if it wasn't, all vehicles will still have points etc. (broke my dwell meter awhile back so I'm biased :)). Again you may consider the expense at this stage or ask for it as a Birthday present  ;).

Best wishes...........

Hi Drummie,
                     I have attached SRM's 2016 price list, they probably have the most experience and it will give some idea.

The issues you are describing sound like an ignition problem. As you've no idea of its history I would temporary add cable to isolate the ignition system to help with fault finding. I have attached a wiring diagram to help.

Best wishes....

Hi Drummie,
                    If the conversion has been carried out it would have been done professionally probably SRM. They would have highly recommended the sludge trap be opened and cleaned, I would expect any person stripping down the engine in the past to clean the trap as a matter of course. It is there to centrifuge the solids ensuring a clean oil feed to the shells, its not to be feared. My guess is that the bike is okay. When you get it home drain the oil, clean out the oil tank, oil tank gauze filter and PRV gauze. Put a pint of oil in the crankcase to ensure oil gets to the top end quickly, the remainder in the tank and restart the engine. Check in the top of oil tank to ensure the oil is returning.

I have recently stripped down 2 engines and found the traps to be in the region of 50% full which would not be detrimental to the oil feed. One of the cranks was original so I expect it contained 50 years of muck.

After the rebuilds I have added an oil filter to the system and use modern oils see:-

There has been plenty of discussion on these subjects a quick trawl through the forums should help further.

I have had a number of BSA's over the years and enjoyed every moment of them, they have been a worthwhile hobby. Take the plunge and enjoy.

Best wishes....

Have you tried this website for ideas?

Hi Old Biker,
                   I have a Boyer Bransden system on my A50 and I'm using a Boyer MKIV on my A65's.

I have completely redesigned the wiring to -ve earth (see attachment) so I can use quality LED's (headlight still QH). I also use quality modern components rather than the copies of the OM stuff on the market.

I wanted to use a Digital Lighting/Ignition Alternator Kit but the alternator only generates 65W. I considered using LED's, but I'm not convinced with the LED headlight quality.

Kit link for information:

I would say do it. I have and never had an issue.

    Acid level will not be a factor.

I believe you have had electronic ignition fitted recently. If I have issues I always migrate to the last item altered, so I would suggest the timing is too far advanced.

If you list all the things you have changed recently and the circumstances of the issues, this forum can help further with a solution.

Best wishes.....

Singles / Re: B31 Timing Side Roller Bearing
« on: 02 April, 2017, 08:44:52 »
     Which bearing manufacturer did Simply Bearings supply? If you are concerned it's worth phoning them.

I purchase 4 needle rollers from them and the quoted loading wasn't what they supplied, they gladly replaced them for me (next day and with the free postage, I had to pay for the return postage though).

Best of luck........

Hi Mike,
             Bikerbob is correct.

The Roy Bacon book states A50 side covers - 1962-1965, Metallic green (39) with round winged BSA badges.

You might find Stirling is a supplier of bearings not a manufacturer, maybe repackaging in some instances similar to Simply Bearings?

Hi Mike,
             Hows the contemplating going?

I found this image, it might help with ideas.....

      I've used valanced alloy or when looking for an original look, stainless, both with success. The stainless, I have further polished with mops before building to get the best finish possible.

I am in the middle of a restoration using a wider rear rim (see image). As Julian said, plus check the chain travel and chain guard. I had to move the guard about 1/4" as it was fouling the tyre. I feel the bigger rim and tyre does look good, when I have it running I'll let you know how it handles.

I use new stainless spokes and nipples. Whenever I've taken out the old they were chromed with corrosion around the threads.

I build my own wheels, it's easier than you think although Central Wheel Components built the rear wheel of the bike in the image. They have supplied parts for me in the past and I have never had a complaint.

Best wishes...
