Welcome Phil, when you can be good to see a photo of your 650.
There is a qualifying period before you can post pics.

Project Board / Re: The rebirth of Lazarus
« Last post by mickwinf on May 28, 2024, 11:21:03 PM »
Lazarus continues to frustrate me and resist his rebirth.started running on 3 cyls, and after swapping plugs etc with no effect I decided it must be a blockage in no 2 carb. So carbs off again and pilot jet had a blockage, then after cleaning carbs back on. Now running on two cyls! Turns out the low tension wire has broken off the coil. A member of our fine forum Simon has offered to do the Ash fix on some spare coils for me so hope to be back running soon.

Anorak's Corner / Re: Anatomy of a 400/4 Horn (also CB250/360 G5)

Update on this.

I found a couple of Honda CB400F style Genuine horns in my stash  the other day that were totally dead. My rig to inject EHT to arc across the contacts in order to revive them....  as described on here previously ...  was at work. So I tried removing the M4 adjuster screw/lock-nut completely and with 12v connected across the terminals I repeatedly pushed down inside the hole with a thin crosshead screwdriver to physically move the contacts apart and together again. After quite a few makes and breaks there was eventually a bit of a squeak and the horn started to conduct current, so I carried on making and breaking the contacts and the current gradually increased until the horn worked perfectly, after adjusting the large centre screw and the M4 'tuning' screw. Worked on both horns eventually and worth a try if you have dead horns.

Hi Phil, welcome aboard! Not so many 650’s that I’m aware of plenty of 400, 500, 550’s. All nice machines of course.

New Member Introductions / Hi from South Wales
« Last post by philoaks on May 28, 2024, 09:56:38 PM »
Hi all.  I'm Phil from Bridgend in South Wales.  I've been riding since I was 16 and now a lot closer to 70 than I really want to be  ;)  Currently have an R1200GS, a Honda CX500 that I renovated a couple of years ago and a more recently purchased CB650Z.  The CB is relatively tidy but low on compression so top end is off at the moment waiting on the arrival of new rings.  Block and head have been vapour blasted to tidy them up and carbs have been stripped and cleaned in an ultrasound bath.  Hopefully it will all go back together again but I may well be back here asking questions if it doesn't.

I plain bought one of these very pretty aftermarket items for my CB400F2. https://www.ebay.co.uk/itm/292633661096
However at least in my case I found the tie rod, that bar between the joint and lever was too long and I needed to use the one from my original, so don't throw away!  ;D

I guess the lithium ion batteries life is dependant on number of charges? We have an old iPad here that the grand kids use now and it is 13 year old now! Battery seems good still. Couldn’t tell you how many times it’s been charged though!🤣🤣 There is likely other factors that determine the life. We don’t usually keep vehicles for too long before we need a change.😜

If it helps I'm pretty sure I have my original one that I replaced with a less than perfect aftermarket one. Yours for the cost of postage if it helps as a practice part. PM me if this is of any use.(Yes it is sloppy).

There is a wire circlip you need to winkle out with a fine pick.

Wow, I didn't know that Ash :o. Well done. Is the bit that suffers the wear the ball or the socket (sounds like a hip joint!)?
