It got me thinking to the last issue bike had when it stopped working at the end of Octiber. The starter relay did that thing where it stopped on and wouldn't switch off without battery disconnection. It did this when it was in a garage getting an MOT so may well have been doing it for a while and damaged the brushes before the mechanic noticed it. He replaced the relay for a better one and I ran it for about a week during which it got harder to start and finally wouldn't.
I got the battery checked at a workshop and it has enough amps.
So I am now thinking the starter motor is damaged and only able to turn weakly and not generate enough sparks. I had a damaged floor polisher which still span but wouldn't polish floors, as it was too slow and weak, which is kind of the same thing!
I have connected my battery to the post on the starter to rule out a bad wire from the starter and still same slow crank.
Yesterday I got a universal joint socket adapter so I can try and get the starter out without getting the exhaust off. I dont want to risk getting the exhaust studs out.
Will let you know next couple of days.
Hope this makes sense.

well you didnt do the check on the coil manually, if you get fat spark when on/off on batt you know problem. Anyway good to have an extra TCI for later..Btw there is no easy way out on the starter motor remove, oilpipe line must out too and exhaust, motor is propably stuck too. Take your time and do this correct and remove carb for a clean when you are doing this. Order new seals gasket oilpipe and gasket starter motor. The 3tb starter runs much faster than the 4pt, sounds almost wrong but seems ok on the ones i have tried.
