careful what you say!

I've always wanted to go visit Burt Munroes house in NZ....
If it's still there.

make sure you bring your swimming gear, Napier is a wee way from Burts place

+1 on the bar end weights, there to eliminate vibrations

Dear diary: today I refitted the wiring loom that I removed all that tacky red tape from.
I am very pleased with the result and if I could just remember where all those figgen wires in the headlight bucket went or stop the brake light flashing on and off for no good reason I would count it a success.
Tomorrow is another day..............

[troppo]

Well done hush..
The wires are pretty easy really, honda was kind enough to  colour code them for us.
Connect the same colours together and you cant go too far wrong

[Hush]

Yeah but why did Poppa Honda make most of them green?
Actually I think my main problem is the wiring I repaired from the PO and he didn't seem to care what colour hooked up to which.
Once the frost gets off the grass I may venture out to the shed and have another go at them.

[Hush]

OK so some wires definately don't colour code, I got it all hooked back up but have no front head lights now!
Trawling through my Clymers manual I find that a #$%* load of wires on my pz are not covered.
Ah well "suck and see" as my old electrics tutor used to say.

[Hush]

Dear diary: Today I finally got all the wiring back into headlight bucket, ran wiring to the back for the red light (why didn't the PO leave it where it was?) and ran wires across to the front crash bars for the siren.
Siren back from panelbeater mate (freebee's I love em) so bolted that onto crash bars, repaired back bracket for the red light and hooked the whole thing up.
Works like a friggen charm.....siren give 4 different tones, NZ Police, USA police, UK Police and the last one I think is for warning other motorists as you crash through red lights!
Bike started easily, engine noise still there and definately the carbs are out of tune.
Am considering getting my friendly bike wrecker who was trained as a Honda apprentice to do a complete tune just so I know it's as good as it gets.
Am yet to source 2 red lights for the front crash bars, 2 small orange reflectors for the forks, new front tire at least, re-vin and register/licence, WOF.
That just leaves a new helmet and finding out the cost of freighting Soos 2 into 1's from states.
But you get the idea from my photos that it is coming together, and very soon it will all come apart as I get tank, chain guard, front guard, siren repainted.
I'm leaving the screen till last as we don't use them much in NZ and I'm thinking it could be a bit of a search getting one of the right shape for the era I'm trying to replicate.
Even my wee terrier Berley agrees

[Hush]

Nuts new camera makes them too big, oh well use your imagination until I figure out how to resize them.

[troppo]

G`day hush
Your doing a police bike, why not do a little research and try to find a helmet that looks just like the ones the cops that rode those bikes wore.

As for your fairing, check your local yellow pages, theres bound to be someone who works with perspex that could duplicate it if its damaged. It would probably be cheaper than trying to track down a replacement that actually fits and looks right
Glad to hear you got the wiring sorted mate, always a headache when someone else has made  a mess of it
Cheers
Troppo

[Hush]

White open face with clip on sun visor and mirror glasses for staunch appeal, "no smint no kiss" ha ha
I'll get an open face for doing promotional stuff but seen too many bad scars from not wearing a full face at speed so I want one of those just for hacking about.
This model has just a screen, if you look at my avatar you can see the original is a simple screen mounted in front of handle bars, I actually have the original mounts so hopefully I can get something that fits.

[Hush]

OK resized piccys, here is CB650PZ all back together and about ready for paint, a few cosmetic items to add as I get them but you get the general idea.

[Hush]

Damn I hate those 4 into 1's.

[fishman_Phil]

I would have to agree with you on those pipes Rick. They do nothing for the bike. Something must turn up somewhere sometime. Is there anyone over in the Napier area that can manufacture headers for you. I am going to get some headers made in Christchurch later this year for one of my 1936 James bikes, but I have got a pattern for them to copy off another bike. Cheers ... Phil in NZ

[Hush]

Dear diary:  OK so new problem arises, I have discovered that those damn 4 into 1 pipes make the bike unridable, they lower the centre stand so low that cornering on the left hand side is impossible!
Hopefully will find out soon the cost of freighting original set of exhausts "Soos" has offered me for free in U.S..
Have recieved list of requirements from my brother in-law bike painter, quite extensive and costly but will make old bike look a million $$.
Still in the back of my mind is the fact that the engine may have to come out again and be stripped down to bare bones to get rid of that deep knocking noise which is probably cam chain past being tensioned or even worse the primary drive chain.
Ah well I'll just look upon it as a massive learning curve and the weather aint good for riding until about October anyway.
May pick up smaller bike for restoration for the G/F in mean time.

[Hush]

Dear diary: while testing the bike today carb 1 and 4 both at different times developed flooding.
Have ordered new set of float valves $45.
Steering head seems to have a mind of its' own and am told it probably needs new bearings and after 29 years probably very true.
Noticed front twin disk brakes are different on application, will remove both and check them out, no point getting bike running well and steering in right direction if I can't brake it!

[Hush]

Cheers Canuck, yes I fiddled with the mixture screws today and the rattle is a lot less now, I'm guessing that if I get them professionally synced the noise will be almost gone!
Will google "spitfire" and check screens out ta for that.

[Soos]

For the cost you will endure having someone else synch your carbs, you should be able to get a synch tool for the same of less $$.

I paid around $50 US for the one I use.
It is one of the simple mercury ones.
Works amazing well IMO however.

I was quoted shop rate for 1 1/2 hours at the local honda shop(60.00/hr), and 45.00 for the job at various other bike shops.
So the extra 5 bucks plus whatever shipping was was worth it.

I have since then made me money back(and then some) on the tool itself by selling it's uses to other local riders who have 2 or 4 cylinder older bikes.
Most of them jumped at it when I told them it will only cost them 15.00 to synch a 2 carb setup, and 25 for a bank of four carbs.

Oh, I looked over those exhausts really good yesterday, and the rust area on both exhausts(4-2) is about 1/2 to 1"(15-25mm) behind where the muffler is welded on to the rest of the exhaust. It has caused the chrome to start lifting. I can't press a nail through anywhere, but it is noticable when on the bike(ok, I notice it really quick). They are a good set of 50/50 pipes.
50mph, or 50 ft away, and they lool NICE...
They do sound good though.
2 of the collector pipes are slightly dented(scratched&dented, no rust, chrome still on there) is on the 2 collector pipes that are removable.

This is one LONG box!!! Seeing as only 2 of the 4 collector pipes are removable from the mufflers!!!!

P.S. The guy at work who will know about the international shipping was on vacation from work yesterday, and SHOULD be there to answer my Q.'s today.
And just how SAFE and SECURE do you want the package they are shipped in?
I can make a custom crate for shipment if interested.
Or I can stick with the box I have got going(cardboard). Either way, i'm Pretty darned sure that they will be undamaged upon arrival considering the packaging going in there with the exhaust.
I have access to a really nice expanding foam made specifically for shipping large/heavy items. My work uses it when they ship anything over 5 ton.

[750K2]

hush - you've got a real gem on your hands, no doubt about that.  certainly a character bike if there ever were one.  and a +1 on buying a carb synch.  i borrowed one and did my own for the first time and i find the added comprehension to be well worth the learning curve involved.  good luck in your efforts and thanks for the great posts!
frank

[Hush]

Hey Soos, I'll go with your efforts mate, way above the call of duty lol, cardboard will probably be lighter than a crate too.
Right now I'd stick 50cc step thru pea shooter pipes on the bike, anything but those God awful street racer things.
I've been testing the siren lately and I think there is probably no drugs left in my street anymore, all flushed "like man the pigs are coming"!
Hi 750K2, yeah I kinda like the strange and different, it's given me extra headaches too along the way as no one has schematics or electical diagrams for all the extra wiring these bikes have but I know it all now ha ha.
I don't expect it to be the fastest thing on the road either as with all that Police stuff it must weigh a ton and is certainly not aerodynamic, how they ever caught any speeders on these things amazes me.
Ex traffic Officers I work with tell me horror stories of getting near the ton and the screen parting company with the bracket and them getting knocked off the bike!

[Hush]

Dear diary: today I bit the bullet and ripped the front of the bike apart, new steering bearings are required and so with trepidation I attacked the problem.
Last bike I had to do this on was a 1965 Suzi t250 and that was a piece of pie.
Anyhow the new ALL BALLZ bearings wont be here for a few days but I thought I'd get the prep done.
Front brakes mystery may be solved while I've got it all torn down.
Should get new front tire on while the wheel is off, we'll see.
Not sure how much grease I will need to coat the new bearings in, hopefully the instructions will come with them.

[Hush]

Dear diary: today I tackled (with considerable help from the forum members) the removal of the bottom bearing race on steering shaft.
What initially looked like a solid part of the shaft was actually a seperate bearing race and came off with some brute strength and pig ignorance, cold chisel and hammer.
Also removed siezed speedo cable screw on front wheel hub.
Awaiting new bearings, hope they are on their way.

[mystic_1]

Save the stock spacer, and races.  Stack them together on the workbench with a few balls between the races.  When the new bearings arrive, you'll need to match this "stack height" using the spacers usually supplied with these kits.

What you're really going for is to have the steering stem in the proper relation to the neck tube.  As long as you have adequate clearance between the lower tree and the steering head, you should be ok.

Bike is looking great.  That siren gives me horn envy!

Edit:  Now's the time to hit that lower tree with a bit of touch up paint.    -M

[Hush]

Ah I get it now Mystic1, the height of the top and bottom races plus the height of the old bearings will be the height I need to set the new tapered bearings at.
I was getting round to asking that of someone but was waiting to see if the new bearings came with clear instructions.
Cheers for that, also take your point on the painting and will do some touch-ups.
Am getting some major parts like tank, front guard and chain guard done shortly.
Am mainly concentraiting on getting bike street legal and ridable so I can get some miles under my seat, steering bearings became a must do when I realised (thanks again forum) that they were coozed.
Paper war to follow with re-vin/wof/registration/insurance and bulk $$$ that NZ government demand to be lawfully ridden.

[Hush]

Took apart the front twin disc brakes today as well.
Can't find anything wrong with them so gave them a good clean up and will reassemble tomorrow.
One thing, the 4 axles that the disk pads swing from (look like 6 inch nails) all had wear spots, shone them up with a steelo pad and that should be OK for the next 30 years.
The PO had set the handle bars too far forwards (no idea why) and consequently the brake reservoir did not read correctly.
Fingers crossed for some steering head bearings tomorrow.

[Hush]

Dear diary: unfortunately no bearings via courier so that's that till Monday at least.
Not to be idle I have removed the top and bottom inner races, bottom one took a lot of hammering and came out in pieces.
Took some time to find all the bits in the shed.
Top one was like finger tight and a quick tap with special tool no# eye bolt removed it cleanly.
I will rebuild the disk brakes and that's it for the week end I reckon........bugga........Hush.

New photos of removed bearings, tank requiring repaint, forks removed, my baby looking very un road worthy.

[Hush]

Adendum: cleaned and reassembled front disks, they look real good and am satisfied braking won't be a problem if I ever get on the road.
That wobbly side is nothing either, just little rubber dust boots that protect the moveable part of the disk so it can adjust as the pads wear, I can live with that.
Tomorrow I shall attack the engine side covers with fine wet'n dry paper to remove horrible paint urg how could he do that to her?
