Dear diary: After a really nice ride of 40 miles yesterday I pulled the plugs to find them black and carboned.
This leads me to believe that my air filter is blocked, its the one thing I had neglected when rebuilding the bike cos I knew it would be rather expensive but now it seems a small price to pay to get the old girl to breath right.
Just got a call from the Honda guys to say they have found me a CB650Z filter at another shop and it should be in tomorrow $80.
Another call from the Suzuki guys to say they have found me a front tire for Jaffas' 400, I can either have an ARC (which is a cheap tire) for $180 or a better Michellin for $180....um now let me see!?
I also belong to a site for 650 Hondas and the guy that set the site up reccomended that owners remove the stock plastic air filter cover and just use two oversized washers to hold the air filter in as the stock cover restricts air intake too much.
I'll wait to get my new fliter and try both ways, last night I removed the filter altogether and ran the bike, she don't like not having a filter eh!

Dear diary: Picked up the new filter from Honda, they reckon the old one I showed them could be the original? 30 years of service now that's what I call dedication!
It may have been actually cos it stunk my car out on the short trip, it smelled like I nad an open can of petrol in the car.
Have yet to try the bike as some idiot let the Aussies send us some perfectly horrible weather, very unsuitable for riding with storm force winds and lots of rain (cancelled the cricket).

Have to pick up Jaffas' new front tire for her 400 tomorrow as well and must remember rattle can of white for the ticket box and base that arrived this week, have figured out the wiring for the wee blue light (why blue?) and note that the MOT made a damn fine job of fitting the tiny bolts and screws that hold it all together.
All ends of screws ( stainless steel screws) have been neatly micropened over so I can't remove them for painting, probably so they didn't rattle out while bike was on duty, ah well I got lots of electrical tape to mask them with.

Dear diary: New air filter makes big difference to the bike, she has some real grunt finally but unfortunately has also developed a slight miss, pulled plugs after ride and all nice brown colour except number 4 which was carboned up.
Now digging into bike to sort problem.

Dear diary:

well what promised to be a good day turned to custard pretty quick, dropped the carb bowl on #4 and there was my problem, dirt/rust/water/paint?.......

With a heavy heart I dropped the other 3 bowls and sure enough rubbish everywhere!
I'm picking this happened when I ran out of gas when the tank was newly painted.

Cleaned all and replaced bowls, ah now for a nice ride to check if that annoying miss has gone.....but nooo gas everywhere the gaskets are not seating!!
Honda dealer tells me that gasket set is $100 per carb...damn must be gold plated?
Old Honda guy at the dealer told me that he uses standard "O" ring rubbers from a local bearing shop, just glue them in place and when set bolt em up.

guess I'm going shopping tomorrow.

keyster makes decent carb kits for the 650z. somehow they're just slightly different from the 650 in the states, but they're alright, just don't use the brass pieces. Having bought the gold-plated honda model to test it out, I can confirm they're ab out the same as the keyster one to be found at half price.

Hush · « **Reply #405 on:** March 09, 2009, 12:39:01 PM »

I'll see if Keyster have an outlet here in NZ.

Hello Hush, I haven't been around for awhile

Congrats on BOTM nomination!
Bikes looking good

when I rebuilt my carbs the bowl gaskets looked like the originals, they where kind of
hard but not brittle and in one piece
when i put them back I use some "Yamabond 5" on the mating surfaces.
(had a tube laying around from my atv)

It's like a thin contact cement,glue made for mating surfaces
have run about 1.5 gl of gas through them just trying to get timing ,idle and charging squared away
seem to work well, have no leaking at any of the carbs

would be a cheap attempt if it didn't work,($4 or $5 for a tube i think) pretty sure Honda makes something like it, but can't remember what it's called

good luck with all the gremlins

Mike

Frankenkit · « **Reply #407 on:** March 09, 2009, 04:27:38 PM »

+1 with yamabond, and my suggestion would actually be just a touch here and there to hold the rubber gaskets in... but it's always worth it to replace the old gaskets for reliability.

Hush · « **Reply #408 on:** March 09, 2009, 10:27:55 PM »

Damn it diary: Am soooo annoyed at not being able to ride that I dropped in on my old mate the bike wrecker and asked him if he would part with that rack of carbs he had when he sold me a float last year.
$50 later and I got me some old carbs to play with, he also sold me the smallest gas filter I have ever seen, check this out!

fishman_Phil · « **Reply #409 on:** March 09, 2009, 11:05:40 PM »

Those little fuel filters work well Hush. I have one on my latest creation. Just get the orientation right though. Normally have a flow arrow on the side of them. They can be tucked away discreetly. The only other thing when adding one to the existing hose is to ensure you don't get the hose kinked when tucking it away and slow the flow down. Keyster carb kits are a good way to go. Cheers

Hush · « **Reply #410 on:** March 10, 2009, 01:57:01 AM »

Yeah $10 each and when they are full of cr*p you just toss them and fit another.

MickeyX · « **Reply #411 on:** March 10, 2009, 06:13:10 AM »

Good deal on the carbs. Now get that puppy running.

Hush · « **Reply #412 on:** March 10, 2009, 04:26:29 PM »

I wish Mickey, aparently today is the delayed International Womens Day...well according to Jaffa anyway and she has me waterblasting the back sundeck!
But tomorrow is all mine cos she's back at work ha ha.

Hush · « **Reply #413 on:** March 11, 2009, 12:21:57 AM »

Dear diary: Well while Jaffa was using the waterblaster I sneaked into the garage and removed one of the carb bowls off the rack I bought yesterday, I took one float and it's bowl (cos the bowl gasket was gone on mine) and replaced #1 on the bike.
I can't believe it was so easy to fix, no leaks no overflows nothing!?

$50 well spent in my case.
Only drawback is that we are having some unseasonal weather and tonight I nearly lit the fire to stay warm.

Hush · « **Reply #414 on:** March 12, 2009, 02:56:24 AM »

Dear diary: A little progress today, had a look at fitting the new ticket box and bracket to the bike.
Strangely the bracket seems not to fit the bike where it should, after much fiddling about I think I have it right but have found that I need to remove the whole rear pannier bag frames just to get it on.

Getting back to the float problem I had, this is the second float I have had to replace within a few months and on checking out the bowl it appears that Honda in thier wisdom moulded a wee sticky-out sharp shelf thing just where the tip of the float would hit it when the bowl was empty.
I realised that I could/should remove this (and wondered why it was even there) but I don't own a dremil which would have been perfect for the job as the little alloy ledge is in quite a narrow area.
Then I had a EUREKA moment and stole Jaffas' toe grinder thingy, its got like 10 different sanding heads and made short work of the alloy in the bowl.

Yes I'm so dead if she finds out eh!

Hush · « **Reply #415 on:** March 12, 2009, 11:34:03 PM »

Dear diary: got quite a bit done today, fitted ticket box and bracket, manufactured the aerial bracket and wired in the ticket blue light.
Even had time to fix Jaffas' registration holder on her scooter!

Had a quick ride, minor backfiring from somewhere, pulled both outside plugs but they were fine.
Gas tap was behaving its self all day and then i noticed some bleeding down the engine casing, ah well I'm used to switching off the gas now anyway.

fishman_Phil · « **Reply #416 on:** March 12, 2009, 11:51:23 PM »

Hush, if the tap is the same as that used in the CB350F, Econohonda have the Petrol Tap Gasket Valve for $13.07 in stock. Will stop the drips. Cheers ...

Hush · « **Reply #417 on:** March 13, 2009, 01:39:30 AM »

Sorry Phil, my bad, meant I should have turned the gas tap off, dripping was from carbs overfilling.

Hush · « **Reply #418 on:** March 13, 2009, 07:45:20 PM »

Dear diary: had one of those "change of undies" moments today after a long (blissful) ride I was heading home when at a set of lights the front end came up as if cellibrating that i had finally got her running right.
Still have that annoying battery discharge issue, might be my next big mission to sort the charging system out.
But just woderful to be able to start and ride.....and ride....and just keep riding as long as I wanted to.
Top end speed has improved and even though she seems happiest at between 50 and 60 mph, there is no hessitation (more like a boot in the butt) if you want to take her up to 70 or 80.
Cross winds seem to worry the handling more than anything and that is probably because of the pannier bags, extra lights, siren and screen.....the old cops that rode these machines earned their money!
She is quite light in the front at speed (something the old cops told me they were known for) and cornering is an art form I'm learning as I go.
But this bike is one heck of a head turner ha ha ha

...............love it, just love it.

Frankenkit · « **Reply #419 on:** March 13, 2009, 08:28:27 PM »

describe this discharge issue- is it just not quite charging up to par during rides, or what?

Soos · « **Reply #420 on:** March 13, 2009, 08:39:49 PM »

Good to hear that everything is running good for you!
You should get her out to that track you mentioned earlier and see if they will let you run the lights and mabey the siren.

Yeah... the kick in the pants at the higher RPM's (6K+) is NICE....
I have found with the way my bike is setup I hit around 45+mph in 1st gear. Great for light to light runs.
(kinda mean on the poor beastie... but Life is short)
Right around 5000/5500 rpm it gets noticably more pull, but (for my motor) right around 6750/7000 rpm it gets another kick in the pants, and the front end gets real light.
Adjusted the clutch recently and got rid of my slipping problem at high RPM in 4th and 5th gear I was having as well, THATS a kick in the pants as well.... 9k-10k rpm in 4th gear....

I wonder if my MPG will go up?

So you got a camera?
Any pic's of the scenery along the riding areas you got?
The pictures of NZ I have seen are quite beautiful.

Hush · « **Reply #421 on:** March 13, 2009, 11:21:30 PM »

Soos, still scratching around for a camera to do the ride along film.

Kit, bike starts at home fine, I do ride with my headlight on all the time (old habit, that's how I became an old biker

).
Even after a good long ride at high revs, when I stop like I did at Jaffa's gas station today the battery lets me down, had to crash start it, only takes a few feet and works everytime.
Just damn annoying and because these older bikes have batteries that slide (make that wrestle) in from the side it's a royal PITA to pull it every few days to recharge.
I raised this point with my old Honda mechanic and he insists that Honda electrics and charging circuits were the better ones the japs made, in fact Yamaha were so impressed they started using Honda rectifiers when theirs turned out to be less than reliable?
None of the two strokes I have had ever developed this problem and two strokes aren't as reliant on a well charged battery as four strokes.

fishman_Phil · « **Reply #422 on:** March 13, 2009, 11:37:06 PM »

Hush ... To make charging easier, fit a small electrical socket somewhere handy to get at, without removing sidecovers etc, so that the positive connection of the battery charger can go to this and ground out the other lead on any good earthing point of the bike. At least that way you can keep a trickle charge going in when you want to. Many classic bikers do this especially when they have several bikes to tend to and use.
My CBX400F was doing much what you say your bike is doing and I ended up replacing the battery. The "old" battery was not old but I suspected it was not doing what it should. Now my CBX400F has the charge it wants every time for starting which I really needed as there is no kick starter to use on it and push start is a real mission with it when cold.
I run with my headlight on with any bike I ride as just like you say, we are still around and people grossly under estimate our a bike's stopping ability easpecially in the wet.
Two-Strokes can suffer with one problem that I have found in the past. A twin will start on one cylinder and after a few minutes the other cyl will try and kick in when starting with a flat battery. But this is only if the charging circuit is working fine and the battery can get feed some juice pretty quick for the second to work. The same fault must happen with 4-strokes as well. Cheers ...

About 1 year ago I bought a (?crafstman?) battery tender.
It came with leads that mount on the battery permanently, allowing the charger to plug into the cord mounted to the battery.
And the need to remove the battery is completely eliminated.

I'm all about ease of maintenance.
I haven't removed mine to charge it since owning the battery tender.

I'll take a pic if I remember tonight.

Hush · « **Reply #424 on:** March 14, 2009, 12:18:09 AM »

Yeah but don't you have to take the tops off the battery to allow gas to escape and disconnect the positive from the circuit?
