Air cooled starter issues

[Ageing Rotarian]

Gents, sorry if I am going over old ground but I am having some issues with the starter on a classic replica.
When you press the button the solenoid clicks and it is switching the current to the starter but the engine does not turn over. If you turn the engine over by rocking the bike backwards and forwards a few times the starter will fire into life and start the engine. Do you think this is starter motor or sprag (or something else)?
Any help will be appreciated.
Regards
Roy

sounds like the starter sprag,I had a similar experience with my Classic,J.B.

Are we talking big job/relatively simple job John? Anything to look out for when stripping the clutch (I guess you can access the sprag once the clutch is removed)?
Cheers

I have renewed and cleaned the sprag on my Commander a few times, I have a how to provided by RN I can send it to you if you wish, the first time is a bit fiddley and you do need some special tools.

Tony, .
drain primary oil .
remove brake pedal.
remove clutch cable & lift plate.
remove cover.
remove chain tensioner .
remove clutch spring .
undo clutch nut & sprocket nut (both should be VERY tight!) .
pull off primary drive .
remove spiral circlip from back of clutch drum .
remove sprag - Seemples! One hour's work. BUT almost impossible without the appropriate tools .clutch spring compressor (same as Commando but with M8 x 1.25 thread up the end of the 1/2" UNF bolt .slimmed 19 A/F socket to get to the clutch nut .clutch locking tool (or use the rear brake in 5th to hold the mainshaft) .balance weight holding tool (or flywheel restrainer tool - and that means removing the water pump to get to the flywheel) .30 A/F socket and breaker bar for the eccentric shaft nut Two hours to clean/inspect/re-assemble in reverse order, with the tools. 100 ft.lbs clutch nut, 150 ecc. shaft nut, both with Loctite 270. 250 cc cheap SAE 5W-30 Without the tools, how close are you to A&E?
Slower, slower! Now the fear of even more points overcomes the thrill of speed.
