I find it difficult to re-size a picture so the post accepts it.

Sorry for late reply,
Yes, all the rest for sale.

A new radiator would be usefull, as well as a new set of hoses for water.
First real test in this week-end track-course. The bike: almost perfect, top shape! except lots of water vomiting at stop. And 30W fork-oil next draining.
The pilot: too old but unfeared with Bridgestone RS10 full-angle that I would never believe!

My second CB1 now for use on road track. All what is not needed there for sales, just ask !
On the other hand, I need Front Disc, Water pump assembly, and radiator.
Question is: do I buy a third one?

Contact on. In perfect silence, I can hear the gas pump pushing for seconds, then stop when enough pressure built-up, I guess.
Then only, I push starter. After 4months winter, yes it takes time (30 sec maybe).

Hello. My CB1 has 110000km now. A love-story really...
Starting this year, rear tire (140x17) comes to touch the handle for saddle release.
I guess the 1989 spring gets depressed.
If the rod is not damaged nor rusted,
I want to investiguate a shock rebuild, including re-heat-treat the spring.

7  General Category / Tech Corner / Re: Spark plug wires/caps revisited on: September 03, 2012, 05:00:54 PM
Only now I process to change the wires.
Read on it: HITACHI 1988 (!!!) they are a little bit dry and damaged in some places...

I will keep same caps and re-use the previous crimps/olives on coil side (they stuck the hell!).
I have remounted wires n1 and 4, left side of the coils that are more accessible.
Found required to pre-tap the wires so the cap screws all along.
On coil , it's a pin (no thread no rotate) but I tapped anyways so the coil pin engages surely into the cable.

Now I go for n2 and 3, on the right side, tougher..

Everything went fine.
12mm X 1.50 is the size.
When the stripped hole is completely cleaned from broken thds, still the bottom of the pitch is printed and used as a start for re-tap. Direct with the tapered, oversize plug (12.5mm base-taper OD) Easy torque (quite a constant effort all the way) does not feel as if it cuts new threads, rather "roll" deeper.
I ratchet up to the end of plug thds, left a little gap under the hex.head, however the washer will take enough thickness. Then remove. It produced fine chip-powder but not much.
Clean with Q-tips before tilting back the bike and flush balance of the oil. Re-clean. Install washer on the plug and re-tight with...hum, some torque enough. It seals OK, I ran 25km.

No chance overheating, though: -2Centigrade outside but sunny I am afraid this was my last ride this year...
Time for me to prepare because the bike and me go to Daytona this year!

No I don't want to change the pan. Not even remove and change the gasket for better access...I disassemble the less possible allways. Change one improves...chances of leakage.!
I wait for mail: one "Piggyback" oversize plug, self-tapping gasketted bushing with inner plug...
I will keep this forum posted if I succeed of fail repair.

I plan to incline 45 degrees on the right so I can access confortably. Keep few oil not drained into pan so I am sure I remove all chips when flushing the last liter (thru hopefully well-repaired plug).

Purchased 12X1.25 oversized + 2201.
Thk-you very much. This site goes in Favorite.
11  General Category / Tech Corner / Re: Drain Plug on: November 05, 2010, 09:10:51 PM
OK. no good taper you are right, sure, I can predict 10 more oil-changes, 50000km at least more fun on the beloved CB1!
The thd is said 12mm I suppose 1.25 or 1.50 pitch. It is stripped flush.
I said "suppose" because, right now, the plug holds on one or two thds and I fill-up for a test. So i can't measure pitch now.
The smartest would be I  re-tap the closest imperial so it is easier to find plug & washer locally, no?

Thank-you for help: it helps...

Good advice (Rachet).
My fault is I want to replug and squeeze the same washer again and again (I should rather change it). Its soft aluminium washer but after so many years of service, the material mated and became harder. Consequently, I overthight to get sealed... this time for the last time!

Yes, there is plenty of meat: I will clean ID and re-tap. I would like to tap 1/4"NPT (18TPI) and use NPT plug. But maybe thread-sealing is not good enough for oil-pressure-hot.?

13  General Category / Tech Corner / Drain Plug on: November 04, 2010, 10:09:14 PM
Am i the first one to f-up the oil-drain threads stripped from aluminium carter?

Like I heard once, I am a "blond"! 50000km and ten Oil drainages after, I finally got it too much torque and the aluminium thds gave-up and now I cry...

I go now on CB1 manual to check plug thread size and solutions.
14  General Category / Tech Corner / CERAMIC BEARINGS for wheels. on: January 16, 2010, 11:17:38 AM
This year, Wheel bearings must be changed. I installed new ones 5 or 6 years ago, anyhow rear wheel plays again...
This time I'd like to switch for Ceramic bearings, full ceramic or hybride.
