Yep I suggest you machine it to suit the split bush as standard.

Hello,
That was the instructions I gave to my son.
I shall have it machined and ready tonight.
Good to have kids !

Excellent!

Yesterday assembled one fork leg and installed in the bike (no puller).Looks promising.
When I get it on wheels will be easier to setup timing.

Will have almost 2 weeks off but November shall be first ride.

Quote from: Steve.S on 04 Aug, 2024, 17:47 My dear Fellow,
As I suggested in a previous post, your half time pinion is shagged out. Also, from the photo, there is insufficient clearance between the inlet pinion and the idler pinion. You seem not to be concerned about this.
Does anyone else agree?

At this point I have to thank to Steve. You are ⭐! I have replaced half time pinion with second hand good condition.
I have replaced key and half time wheel as well.

At first hearing (just kicking) I do not have that clicking noise anymore .
To be confirmed when I start machine again.

Could have listened to that advice sooner...thanks again Steve .

Very glad to be of help. You're doing a fine job, made more difficult by having to source parts from overseas. I admire your perseverance.
Make sure there is a very small amount of clearance between the teeth of the inlet cam and the idler gear. If there is no movement, you need to investigate further.
Powodzenia.

Hello,
I'm back in the game ( been off for almost 2 weeks).
I set ignition timing yesterday. Not overthinking it too much. Motorcycle started second kick.

Huge difference! No noise from timing gears nor from pushrods! Feels good 👍.

Now will close primary chain cover using cork gasket. Shall I smear one side with some sealant?

This all sounds very promising! Like Steve S. I admire your perserverence. Please post some photos of the bike when it's all finished and back on the road; I'd love to see it, and I'm sure that all the other bods who have commented on this epic tale would like to see it too.

Sealant isn't really needed, but it does help installation if the gasket is stuck to the cover with something; you could even use a little grease. I poke three or four cover screws through the cover and gasket before I offer it up; this helps to keep the gasket properly located.

Good hint Rog!
I will take that advice.

I will try to make some video or ask my son to make one for his Instagram and will share the link.

It won't be that soon as he got girlfriend and leaving independently hard to get him home this days.

Short term plan for BSA:
- sort it primary chain case(put oil)
- install tank
- get the first ride

Long term (before next summer):
- sort out wheels (might need new spokes)
- new tyres
- make new electric installation (DVR2P already at home)
-prepare all for registration as Veteran
- ride into the setting sun

Grease the cork gasket and don't over tighten the chain case screws, just nipped up.
Small amount of oil so the primary chain just touches it when kicked over.
Mine is completely oil tight after following those rules.

Hello,
Some news today.

I have taken BSA for a first ride.
Clutch works fine .
All gears engage no problem.
Advance system ok with timing. Easy start.
Suspension finally works as designed.

Some failure!
Piston is catching after 10-15 minutes ride.

I think piston is too tight...or the materials used for it's production are wrong.

Few minutes for cooling and all goes again ok for couple of minutes.

Need to take camera to check the inside of a barrel....or strip it again.

Need to call the guy who made barrel and piston for me...

I had similar issue with an Italian `Gandini' piston (can't remember if B31 or B33) IIRC I simply dressed the high spots off, glaze busted the bore and fitted new rings, seemed ok after that  but memory is hazy and it was over 30 years ago when my main steeds were Triumph Daytona 500s!

Maybe not bored to correct clearance?

Dan_B33

Looks like too tight fit. So if Im right that won't go away wit a time and taking off head and barrel again is needed.
Luckily it is before winter otherwise I would go mental.

My son promised to drop short video to his Instagram. I will share the link as soon as I have it.
