Re: Newbie

Hello, good evening, and welcome. Lovely Elsie.

Z1-B is a good choice but I think you're going for the wrong colour. Pic shows the correct colour for your inspiration.

Re: Z1-B Front fork clean

Further to the above I cannot for the life of me find the torque setting for the damper cylinder bolt (44041-040). It's an M10 Allen bolt. It's not listed as a specific bolt in the shop manual and in the general torque settings M10 bolts are listed as having 1.25mm pitch in the "Fine" cate...

Z1-B Front fork clean

Can any of you kind folk confirm that I have the correct sequence of bits on this Jan 1975 build Z1-B fork damper (I believe it's a 44022-028). Also, what's the current thinking on the best oil to use in the forks. Manual just says 170ml of SAE10. I know this has been discussed before but the last r...

Re: Ignition loss

Rob and Warren...many thanks for the advice which I will put into action. I had separated the coil base from the bracket with layers of felt to reduce vibration but didn't consider the issue of heat dissipation. Will now remove the felt and check for clearance between the coil and bracket. Again, ma...

Re: Ignition loss

Fitted the OE type pattern coil yesterday and it fired up first time. Al, good call re the charging system. Now that I've got it running I'll check through the system and record the voltages and then contact Dynatek to see what they have to say. I've got both coils sitting on a felt strip to reduce ...

Re: Ignition loss

Warren...good idea in theory but I only have one original coil (the other disappeared in the passage of time). Is it OK to run one original coil and one Dyna S?

Re: Ignition loss

Got the bike home Friday and today I did a quick visual inspection of the ignition wiring...no obvious breaks or chafing on the insulation. Took both coils off for a visual inspection and then tested. My multi-meter and test lead combo registers about 0.7Ω internal resistance. Coil 2/3 looks fine wi...

Re: Ignition loss

I'm assuming it's been fitted correctly as I did it myself in 2021 and I've had no issue with it up to now. The 10A fuse is inline betyween the battery + terminal and pin 30 on the relay. Pin 87 on the relay supplies power to the coils. The 30/87 circuit in the relay is the high-voltage circuit. It'...

Re: Ignition loss

Warren...I didn't manage to get that far having only one fuse left. I will try a more exhaustive approach over the weekend when I get it back home. Many thanks to all for all the advice so far. Watch this space!

Re: Ignition loss

Update:Apologies but I actually posted some duff info in my OP. As it was dark and I was knackered after a 4 mile walk carrying my bike gear to get to the nearest Halfords for a fuse (which I thought was the only issue) I thought the fuse was intact, hence suspecting the relay. I returned to the bik...

Ignition loss

On the way to Poole Quay Bike Night last night the Z1-B decided to go bleurghhh at a set of lights in Poole (nearly 40 miles from home). I managed to get it into a side street to check and on cursory examination found a blown 10a fuse (I have the "Wired George" mod and it was the 10a fuse ...

Re: 1975 Z1B

Haydn, Fair enough. I also have a Z1-B which I've owned from new (bought May 1st 1975) although it was in pieces for 43 years. I think the general opinion is that they are the best of the Z1's to ride although not maybe the most desirable to own. Pic of mine attached (although a UK bike it's fitted ...

Re: 1975 Z1B

Just interested in why you would swap a UK Z1-A with a USA Z1-B?
