SF2 Owners, Help, Please?

Mine also came w a dirty and broken air filter and the carb slides were badly scored so inspect yours. Dam Classic sells a nice billet sump cover w magnetic drain that simplifies oil changes

My experience with replacement air filters in 2 SF2s and a GTL over close to fifty years is that none of them fit as well as the original.

The K&N is a little narrow, the VW style Weber replacement is a bit wider (and can be significantly less expensive e.g. Jbugs VW filter) though still not fitting around the embossment of the back plate so my approach is to put a strip of draught excluder self adhesive door sealing foam strip around the groove in the retaining plate to fill the gaps resulting from imperfect alignment.

Yes, but the KN has a soft rubber surroynd which moulds nicely on the original mounting.

Hi,
As Paul says, the K&N filter fits well - it's part number E-3952.
Regarding the battery, I've had a MotoBat on my 1974 SF2 for several years and am really impressed with it.

My engine/frame numbers are 179xx.

Enjoy the bike!

Andrew.
 
I also fitted a K&N E3952 air filter to my SF3. I remember heating it to reshape it slightly but it fits well.
I fitted a Motobatt BTX20U about eight years ago and it still starts on the button.
 
I got my V belt from an industrial bearing/parts supplier Gates Truflex#1210.
Instead of prying the new on, I temporarily unbolted the generator clamps, fed the belt and bolted the generator back on

A little surprised you'd say it is DD'ed!

Unless it's been seriously abused in some hard to imagine way (it is in the shelter of the dry case) it's a little hard to imagine that this infrequently used, low stressed chain is really DD'ed - I have never replaced one on bikes that have done MANY miles and MANY starts. Give it a clean and examination before you assume it's DD'ed. If the starter motor briefly growls on motor shutdown that's totally normal, means the sprag is in fine shape.

Ordered one, this morning. Thanks, Teddy.
The old one has made a nice job polishing the inside of the case.
If only I could get it to do all of the outside of the cases.:unsure:IMG_8304.JPG

a bit as Paul says, but wash it in parafin and then oil it, they always look slack, there is no adjuster, its not needed, it only turns when the starter does, the belt is a Z495, that is Z section 495 mm length, online for less than a pint of Mckewans.Ot pickup from Bess at Toogoods, South Godstone.
As previoiusly said, for the chain IF YOU REALY MUST shorten an old triple cam chain. easier if you get the extractor from the club, fiddly if you dont.
