Hi All,
    Has anyone had experience of these air filters:

I'm considering using them on a Lightning and Thunderbolt, the bikes will have side covers and generally standard around the filter area. Is there any issues I should be aware of?

Hi Brown975,
                       This is worth a read:

20W-50 traditional will be fine for the engine.

With modern advances, a gear oil for the gearbox say a 90 hydraulic oil or as Julian says 80/90 EP GL4 gear oil (gear oil between 80-90 is fine). Primary a SAE 20 seems to be the consensuses, you can use SAE 20 fork oil for its anti foaming properties.

Best wishes...

     The BSA service sheet mentioning the use of detergent oils.

   Engine - if you have a preference for synthetic 15W-50 part synthetic although 20W-50 traditional will be fine for long term use. (BSA have a service sheet discussing changing to detergent oils)
   Gearbox - 90 hydraulic oil although SAE 50 traditional will be fine.
   Forks and primary - SAE 20 fork oil (better for anti foam) or you may get away with a 46/68 hydraulic oil at a push.

Worth a read:

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....
