Got the bearings installed in my cases tonight at George's place. We also did the bearings in a set of TR6 cases for one of his builds. I do have one little issue to address, the pin that indexes the bronze washer at the little roller bearing was sheared off, I'll have to cut a new pin and drill the case and install it before installing the transmission parts.

You got a pre OIF Bonnie and criticise CB360's? ;D
I've done a ton of ework on them over the years first shop I worked in was a Triumph/Honda dealer (I think I may have started before 1978 as I remember we sold Jubilee Bonnies and that was 77)
You can make them pretty quick and reasonably reliable (120mph 3~4000 miles between major breakdowns)
OR you can make them reliable (except the zener diode mount and wire connector
)
They are a ton of fun when running though much more torque than XS650 (at least it feels like it to me?)
Is that a T or a GT bottom end?
Looks an awful lot like the T305 I'm still messing with

Not as nice as vapor, but still good. Soda is soft enough not to altar bearing surfaces ect.
Before and after. I did some de greasing before blasting, but you get the idea.

Yep, I'm quite the glutton for punishment... (Looks like I'm getting into another '63 Bonneville too, it's just a front frame and bottom end... it'll get made into a sparsely appointed hard tail bobber.)... I love my 360 but it's infuriating too...
I did that XS650 bobber last year... that bike was fun. It was running pretty strong... over 5k rpm it pulled really good. I've got a small group of friends here that have about 10 unit twins between them.... So I've got good support for the Triumphs... plus this one is going to be 100% from the ground up refurbished... should be extremely reliable at least as much as they can be. For the 360 I've only this forum and Eric sorta locally and a plague of issues... hopefully I finally put an end to those in a week or so. That bike is a blast to ride... handles like a bicycle, you can do some serious cornering.

That's pretty much exactly how I feel about them but everyone I knew had at least 2~3 other bikes to run around on while trumpet was being rebuilt again
I still have a couple of 1950's BSA A10's, not sure when of if I'll get to them though :'(

I like BSAs... I'd like to do a Rocket sometime but the values of them are not strong enough to warrant the expense of a proper restoration. I can't stomach doing another bike that I've invested way more than it's worth into. (Like my CB360)...

Thanks, this is my first proper restoration... I'm trying to cut zero corners and make a worthy bike out of it. The machinist already had my head finished, pistons should arrive in the next day or two. I expect to have them back Monday. The build should start going pretty quickly now... I'd like to wrap it up before labor day if my paint work gets finished by then.

Not much progress the last few days... George and Garry came over tonight and we inventoried my engine parts and sorted through the bulk of the fasteners and parts that came back the plating co. and took note of the stuff I need to get on order to get the motor together. Company this weekend.. so next week more to come.

Picked up my head and cylinder front shop today... Those are ready... Parts came that I ordered too... Thanks to a discrepancy in the parts book, I had to get another order put together. I have company this weekend so Monday or Tuesday I'll get another building session.

Dang, that block is clean. How did you get it so nice? Mine, after sitting and rusting for 40 year was nowhere near that clean looking. Did you make your engine stand? Sure make working on these motors bunch easier. I need to add that lock screw nob to keep mine from turning so easily.
Got back an estimate from a vapor blaster:
$70 / hr.
1-1/2 hour for cases
1/2 hour per engine cover
1 hour for tranny box
1-1/2 hours for head
1 hour for a rockerbox
6 hours unit engine
7-1/2 hours pre-unit
If you add the shipping both ways, insurance, etc.,
$550 unit engine
$655 pre-unit
Yeah...
