Worked on top yoke to get it fitted onto Honda stem yesterday.
Spraybombed bottom yoke
Got real impatient this afternoon after work.
 Decided to fit front end and see what spacers, etc I'll need (plus, I really wanted to see what it's going to look like)  :D
 Didn't have time or inclination to empty garage so worked in the walkway (my wife would go nuts if she saw this, I've already taken over a bunch of space  :o)
It's going to need suspension travel shortened a bit (probably down to 4") and will still have a couple of inches of fork sticking through top yoke.
 I can always put bars on top if it looks too much
Here's some pics  8)

Not using the pit-bike front end??

That does look extremely nice my friend.  That shouldered wheel does it for me with that drum.  Nice nice combo.
I get not knowing, but I can't for the life of me understand not trying. It's only metal it can be fixed. Man up and risk a mistake in exchange for a lesson.

Thanks all, I knew it would look good, just didn't know how good  ;D
Now I'm deciding if I'm going to paint lowers black, leave silver or polish?   ::)

Hillsy,
 The blue forks are stock 1992 (?) GSXR 750, (one year only)
 Would be perfect length for 360 but I dont want 17" 3 spoke cast wheels and I think they may look a bit heavy?

Ahhh...so they are. I saw the blue and I thought they were pit bike forks ;D

I think you're right - USD forks would look too beefy for that front end.

Nice stuff ;)

Just a quick update while I'm cooling off and having lunch (laptop in front of TV is great   ;D
I look like I'm working under a sprinkler, sweating so much  :o
 It's a bit warm here, 91 degrees outside, 80 in garage (have to have door open)

Took a couple of painkillers this morning cos' I was hurting a bit  ;)
Anyway, took top end back off motor after checking cam timing, almost 0.080" rotation of cam relative to sprocket


Forgot to post pics of front end before/after
This is what I started with for top yoke

This is how it looks now, top radiused, hole bored to fit Honda stem still needs a bunch more work, de-seamed, polished, etc (may paint it though? thought's/comments welcome)

Still have to strip forks and lower them (going to shorten suspension movement to about 4" total instead of 5.1")
 Probably won't pull them apart until I get new seals.

Nice top clamp, what's that from? Hell...if it's smooth enough I'd polish that thing, it's so simple and clean looking, it would really stand out nicely.

stock 'Pre 98'  Katana.
 I couldn't leave it stock though, too angular, so, had to radius the top edge.
 I'd like to get some 99 GSXR 600/750 forks, they look exactly like Kat ones but are almost 2" shorter, plus, full cartridge.
 That would be total overkill though and would mean getting real good shocks to match

Made some new throttle cables this morning, hope to make some 'crescents' to fit into cam sprocket later today
I can then re-check cam timing and finish building motor.
 Ran some numbers with present cam timing, need to make front pipes 3" longer to collector and 7" shorter at tail end compared to the system I made for testing.
Numbers will change, depending on where exactly cam timing ends up.
I'm hoping to be around 47~49deg before BDC (at 1mm lift)
 Made this Saturday, MkIV tach drive block off plug.
 It's evolving every time I make another one  :D

Ever had days when nothing goes right?
 well, I did on Thursday, Friday almost as bad (doctor appointment, physical therapy)  :(
 Made several very small parts and managed to lose them, eventually made enough parts to make new throttle cables for both sets of  VM carbs, (XS800 and CB378. )

 Lost couple of sets of 'crescents' for cam sprocket holes so, after about 4hrs losing stuff, gave up and went to work

 Today though, ever had a day when everything goes right, almost by accident, it still goes right  ;D
 Wife didn't want me getting oily in garage (we had to go 'visit' people) so I only got hour and half tonight

 Made crescents for cam sprocket, took about 15 mins (from a 20mm bar.  :o)

 They fill up the space where bolt holes got filed out to slots, sprocket can't move when engine is running (read reports of CB350 sprocket bolts coming loose and/or cam timing slipping)
It's not the correct way to re-time cam but it is less work than doing it correctly and, the timing marks 'almost' line up so there is less chance of getting things wrong in future (correct way is slot one hole only, advance cam one full tooth then adjust timing to where you want it, do second hole to line up with bolt edge on cam)

 7mm outside diameter, 7mm inside diameter, 0.064" offset.  8) (this only works for my skimmed head)

 dropped cam sprocket bolt Thursday, couldn't find it anywhere, today, almost stepped on it, it was just 'there'  :D

Cam timing is now  (at checking lift)
intake opens 10 degrees before top dead center
intake closes 34.5 degrees after bottom dead center
 Total open = 224.5 degrees
Max lift 0.320"(not corrected)
 
exhaust opens 48.5 degrees before bottom dead center
exhaust closes 1 degree before top dead center
total open 229.5 degrees
 max lift 0.310" (not corrected)
Surprising, thought it would be substantially more on intake than exhaust?

I guess that's why CB360's  don't run as well as CB350's?
 Not ready to spend $400.00 on a 'race' cam though, particularly as stock 'mild' cam allows 11,500 rpm


Normally timing mark is completely level with gasket surface, this one 'lifts' to left. You can just about make out timing pin at 6:00 o clock position lining up with factory mark on oilseal housing
 How close did I set things?
this close
