Can I have clarification please, is removing the precats without removing the manifolds an accepted method. Is it easy to remove everything without any "bits" remaining in the manifolds?
6 of one and half a dozen of the other! Some say there's a chance on start up to expell any loose bits you can possibly suck some of the broken honeycombe back into the engine.
As I couldn't be sure if this would actually happen I chose to remove manifolds and do them on the bench.
It's pot luck, my o/s one came out in a few big chunks and was easy but the n/s was a pain and took a good hr to loosen and break it up enough to remove it. Hundreds of broken fragments came out.
All I'm saying is I'm glad I removed mine off the car to do it.

You drill the holes in the cats as many times as you can with a 10mm long bitUse the hose off you vacuum cleaner to help suck the dust out along the way
Then as stated by other use a long cold chisel or thin bar and hammer and prise the cats away from the manifold edges into pieces that break up and you can pull/lever out...BE PATIENT
Use the vac throughout to remove the small pieces
When out push vac hose in as far as you can,I taped a piece of thin pipe on the hose for better access into the back of the manifold
Finally I started the engine and blew any remaining fine pieces out...job done

I can see it now, I will have been at this for a few hours and the swearing it becoming more frequent only for the wife to stroll out and ask how much longer I will be.Use the hose off you vacuum cleaner to help suck the dust out along the way

you gotta stop reading them comics on the train 
My older brother who's into his 60's has suit cases full of comics from the great comic era, post war sort of thing. Must be worth a fortune. Thousands of them. He's likely to have read them all 3 or 4 times over, reads a book in hours rather than days,,, not like me then

Bet he doesn't read Haynes manuals in the bath.....unlike his brother.....
it's true. He was 22years old and I fixed his TS 250 motorbike,,, I was 12 He thought he could fix a simple throttle cable but put it together so you had to twist the throttle the other way
I was lucky as my best friend was 2 years older and we'd been fixing push bikes to race for years by then, the look of joy from my older brother that day when we got it working properly was priceless and I realised it takes all sorts 
By 1980 When I was getting into building a £20'wreck.
I had a 1972/3 version with the drum front brake but my manual covered the later bike with disc brake 75/6 ish so the manual came out later. Hahah. Re built that engine, mains/big/little end/piston and rebore, the works and it was proper quick, only the very latest and newest Suzuki AP 50 could keep with me. Gilera's left for dead. Power pipe that took power away
Saying that back then I'm sure I got most my information passed down to me as it was them days

One of the classic and dangerous errors in Haynes it seem was in the BSA C15 manual where it showed the way to fitt eh oil pump gasket so it blocked off the oil feed to the big end. Haynes of course denied any responsibilty. A young friend at the time followed the manual and required a new big end and crank rebuild shortly after. This was about 1977. Autodata used to print good manuals.
