Wotcha.
I've got the dynastart kit from Paul * - it's currently sat in
the kitchen ( and has been for months ) waiting to be fitted.
I'd best measure my existing dynamo pulley before I go much
further.
* EDIT - I think it's actually Peter.

Just a quick Dynastarter update for anyone thinking of going
down this route
I am very grateful for the great help and advice I received from
some members on the forum , and I just thought some members may
be interested in an update, some months down the line.[/quote]
That's great news Lee; glad it's worked out for you, and thanks
for posting the update!

Wotcha.
Old pulley measured - and found to be 90mm.
Smaller pulley bought, along with a 17mm taper lock coupling and
a suitable vee belt . . . £12 . . . . let the fun begin.

Yes, I've managed to start mine by hand too Randall, but not
very practical if you stall in traffic!
Great video!

That's useful LW - for the ignorant amongst us (me) can you
please point to the taper-lock and the smaller pulley.
I don't know that system

The pulley on the right hand side is the original Guzzi item.
It's 90mm diameter, and has a 15mm diameter hole in the centre.
Rather than make a new pulley, it's easier, cheaper and quicker
to buy a ready made one. They are available off the shelf and
come in a wide variety of diameters ( and belt sizes too - both
single and multiple groove ).
Now the snag with off the shelf pulleys is you need one suitable
for your shaft diameter - that's where the taper lock bush comes
in. The taper lock bush is the small item in the centre of the
picture. These have an outside diameter to suite a range of off
the shelf pulleys, and an inside diameter ( I think they range
from 10mm to about 30mm ) to suit your shaft diameter - in this
case 17mm
The pulley on the left is the new smaller item - 70mm diameter
and a large hole in the centre which takes the taper lock bush.
This bit of YouTube video shows how it all works . . . . I've
used much larger ones when I was at work - for coupling the
motor to the gearbox on passenger lift installations.

Excellent LW; my experience of belt drives goes back to the
Fenner book in the early seventies, but I've never ever had to
design one since, and things have clearly changed.
I take it the belt angle was something standard then?

Yep - standard "wedge belt" - SPZ is the prefix ( available
on eBay for £3.39 inc postage )

Thanks!
Did you note Randall's comment about the length required to fit
over the flywheel?
