SRM Clutch etc.

SRM cush nut and clutch pressure plate fitted - looks fantastic - just a shame that nobody will see it!

Certainly looks impressive, any noticeable difference to clutch operation? I'm pondering over getting this set up myself.

I have the same set up on my Flash including plates cups and springs. The action is as light as a japanese clutch, doesn't drag, now has nice clean gear changes. I'm really pleased with it.

Its a shame SRM don't do some improved set up for the six spring clutch, but then, with the six spring plate being much thicker I wonder if an alloy plate would be of very much improvement?

Yes it is a big improvement.
Buy the top hat adjuster , the radial roller bearing and the mushroom lifter.
Knock the pushrod cup out of your existing pressure plate and the top hat adjuster will just slip in from the inside.
You can slop a bit of Davcon on it if you feel you must but it will happily sit in there .
Use the adjustment nut to bolt it in tight, slip the rest of the bits in, remove the adjusting bolt from the gearbox and measure how much to chop off the end of the clutch pushrod ( should be around 1" to 1.5" ).
Some one in the USA does a 6 spring pressure platee I think it is Britcycle or British Bike Supply Co but their kit make the SRM kit look cheap.
Bill ( now deceased ) used to sell a similar bearing set up for the steel pressure plates and they made a big difference.

Yep! The SRM clutch stuff does exactly what it says on the tin. Really precise control (how often have you heard the word "precise" and BSA in the same sentence?) smooth action and it looks like it's made to last. The weather is due to warm up later in the week so I'll give it a longer run then - but right now I'm very pleased.

Yup! worth the money. Smooth, light and long lasting providing you buy the radial top hat at the same time.

Yes I have an early one (without holes) - one finger clutch operation
To be fair I also have a Lyford Classics one that works well also though does not have the little needle bearing
All the best - Bill
