Members' Gallery / Just a little more tweaking required

It's a rough old test rig, but it's saved a lot of leg work over the years.  The Z1 still needs some tweaking but it sounds fine. Too loud for cruising around Tuross Head  on a Sunday morning.The muffler has nothing inside, just a straight through pipe and it sounds loud in the shed. Finding a choke lever for the Carburettor might be difficult and the correct Magdyno is being refurbished and will be fitted before I put the engine in the frame.  It's idling a bit high, but I figure it's better initially to keep the oil pressure up.  I am amazed at how smooth it is.....some of the old Harley engines I have run on this rig have shaken the spanners of the wall.

Thanks Steve, Yes I have been following that stuff. Mostly earlier parts than my 1934. So far nothing of use to me.  If you need anything posted to the UK let me know. We have an Auspost contract and may be able to get a much better shipping price than you would get from an ebay seller. One of the strings to  my bow is I run the 3PL contract for Hobbyking.com in Australia and New Zealand.

Hi Doug,

Thanks for the reply. Did the 60.5 stroke ring any bells? I'm guessing on this model they used something that was already to hand.

I'm going to attempt my fix and use that to measure the exact stroke. Should the fix not hold up, then I think making a new central web will have to be considered. Luckily I don't need the oil ways!

Cheers for now
Doug

Hi thanks for the quick replies, unfortunately although I have a collection of gearboxes from the thirties, two rack and pinion selector and three level and slider selection, none of them have that pinion gear either fitted or in the box of parts which came with them.
I have been trying to find a pinion gear for quite some time but without any success so if it comes to it I'll have to see if I can get one made if you could let me have the details Ian.

As far as the timing is concerned Doug I at first wondered what you meant, on reflection of course the pinion and rack have to be set up to synchronies with the gear selector lever and tank plate. I haven't actually got that far yet but now see it's something I'll have to deal with when the time comes.

Thanks again
Chris

Chris,

Are you trying to time it? Is it missing?

Thanks Steve,
That is the bike I bought from HandH Auctions 12 months ago.  It's now in my workshop in Australia in a lot of pieces.  There are a lot of parts missing from the gear box and rubber buffers are just 2 of the missing parts. All the springs are missing too. I suppose someone needed them, The gearbox has been apart some time ago and not re assembled correctly.  Not to hard to work out the assembly.

Hi Chris,
I have my gearbox apart at the moment. What information do you need. Here are some photo's which might help.  I am missing the kickstart return spring which I have ordered from the Douglas Spares guy Alan.  I am having difficulty with identifying the model of gearbox without pulling it completely apart. I can identify it a a 4 speed box by the number of detents in the selector shaft but when I attach the foot change I can only select 3 speeds. i guess I will need to pull it apart for a positive ID.
Tell me if you need dimensions and specs for the gear. I can pull it out and give you spme close up pics and measurements that a gear cutter will understand.

What a lovely "thing". Can't really think of a use for it - which is a great shame!
