Hello Angus. Post 1972, no modifications required on the install of the Charlie’s style filter. I’ve been running them in all my OIFs for 16 years and are very pleased. Thanks again for all your hard work!

Thanks Mick for the advice and kind comment.

There's something very satisfying about watching the chain slowly sink into the tin of wax as it warms up on the stove. If you did want to return the filter to original spec, it shouldn't be as difficult as you think (although I wouldn't personally, because I prefer the paper filter). I think the pipe through the top of the strainer was on earlier versions of the OIF. My 78 originally had the top hat strainer without a hole in the top, with the pick up on the front of the base plate, the same as the Charlie's conversion, so you should be able to just buy and fit the original spec parts if you want to. You could even use the Charlie's baseplate with the stud cut down to fit inside a new top hat strainer (or remove the stud and replace it with a short 1/4" UNF blanking screw).

Thanks again Rick I didn’t appreciate that the oil pickup changed on later OIF models; however, we’re keeping the Charlie’s anyhow.

Will the coils need to be replaced by 6V versions to suit the mentioned electronic ignition?

Good point - yes indeed they may well have to be and I haven’t checked that yet until I start reading up on the pazon kit we have for it.
