 Suits me next winter

Hi John
They are available as a self fit kit the instructions have step by step pictures with captions or I can fit them at my workshop but ther is a long waiting list for me to fit one in Cardiff, South Wales

This might be a question for John Chaterlea.?
Yesterday I decided to change the gearbox oil from 30 grade engine oil (as BSA recommended) to Gear Oil 80-90 (both similar in viscosity), and add some slippy stuff to quieten the 3rd gear growl and hopefully to improve shift. Nothing wrong with the 30 grade - fairly new.
However, the starter motor is in the way for access to the drain plug (You'd have thought I would have thought of this before ). I could get it out with much spanner work, but no finger access to get the thread started to reinstall the plug. I decided to leave it alone but add some slippy (Penrite Shift-eze 10%).
Next option is to remove the outer cover and tilt the bike over, or remove the gear indent plunger??
Any easy solutions?

G'day Col.
If removing the plunger gives you enough room that would be my first attempt. Just count the threads. Bike on it's side would be even better.

seen some pic of the one Pearson has installed on Goldies.. looks quite neat as its a small chain to the front sprocket on the primary drive ( must have some sort of sprag clutch )

Wotcha.

There's no sprag clutch - the starter drive sprocket spins at roughly three times the crank speed.   With two chains running side by side you can guess what's likely to happen.   Twice now mine has had the starter chain snap and fly around with the clutch.  Luckily it never locked the rear wheel.

I've removed the electric start - as far as I'm concerened it's just too dangerous to be used safely on the road.  A pity really, 'cos it's a damn useful thing.

Hi All,
Col,
I have not looked at the problem of removing the drain plug (yet)
As Muskie suggested removing the indexing plunger might be easier?

Lone Wolf,
When I looked at the Pearson Goldie set up I did wonder about the speed the driving chain and its little sprocket shaft would do? I cannot remember now or where the sprag is on the GS set up, There has to be one
The A10 starter is gear driven and the gear spinning with the crank is not spinning at anything like speed of the GS small sprocket

I have the McFarlane starter fitted for two years now and am very happy with it
I changed the primary case oil last Friday as we were going on a trip on Saturday , It must have lost some since I last checked ??? but there was no metal in the drained oil
I filled with 10/ 40 motorcycle oil and taking a quick trip around the block felt it was running quieter ?

Hi John, Thanks for the reassurance that I'm not alone and thanks Musky for you putting me on the right track.
 I have a spare gearbox which I want to go through soon. While swapping it over, I'll look at whether I can fit a 90 degree fitting to take the drain plug out to where I can access it - it would be well-protected by the starter motor. No rush yet - the Penrite Shift-eze has improved the gear changes and is a little easier to nudge it out of 1st when I stop. I took the bike out for a fast (for the BSA) 80 mile run today with the Newcastle Vintage Club. Faster than I would have normally, as there were no vintage bikes on the run - only moderns and big ones too!. It has done about 500 miles since overhaul and was a great opportunity to give it the berries and see if it would survive. It did with flying colours . AND--- the electric starter worked a treat .
