CB400/4 ENGINE STRIP, ASSESSMENT AND REBUILD BY JULIE - NOW COMPLETE
Orcade-Ian:
Hi Julie,
I'm really enjoying your regular updates and having just done my spare 400/4 I'll willingly accept the subliminal bollocking I got from you for not sharing this with the forum! Although I have written many pages on my site with bike and car rebuilds and quite a few articles in Tansha and Jaguar mags, I seem to have lost the enthusiasm for recording all this stuff - although I've taken lots of pics just in case. Might be the fact that I'm 69 next birthday and if life were just one day long, then it's nearly 23.00 hours!
Your thread has really hit the spot with old hands and newbies alike, so keep up the good work!
Very pleased that you had success with the slightly unorthodox method of stud removal - it's worked many times for me.
Many years ago I bought a knackered old BSA 150 Bantam which kind of ran but wouldn't pull when you tried letting the clutch out. Only when I stripped the engine did I find there were NO piston rings in it - so I'm not really surprised that your bike actually ran.
On the oil up the studs question, doesn't it go up the two outer ones with those rubber seals between the barrels and head?

Now, a question i cannot find the answer to in either the Workshop Manual or Haynes. I know on the CB750's, oil comes up two of the head studs, the centre rears. Does this happen on the CB400's as well?. Not necessarily the centre rears but the two end studs on this engine were not corroded in and came out very easily when I was investigating. I have looked at the oil flow diagram but can't see for sure if this happens or not. Any insight much appreciated.

just look down the stud holes for drillings going off at angles, if they have the answer is yes
Nurse Julie:
Thanks Ian, I'm pleased you are enjoying reading about my tinkerings, I'm really enjoying the hands on work and sharing it with others, it's good fun.
You have confirmed my suspicions that the oil goes up the two outer head studs, that's why they were nice and free as the oil coming up the thread has stopped any corrosion setting in !!!.
Edit....Yes, I did mutter a bollocking directed at yourself for not sharing your rebuild but I can understand why you didn't :) :) :)
