Salut! Merci beaucoup pour les infos - et c'est super d'avoir contact d'un fana de falcone de l'autre cote de l'eau qui nous separe! Je pense qu'obtenir un 70mm pulley sera la chose la plus difficile et a ce moment le plan le plus possible c'est de demander a un ami de fair un pulley pour moi! Seulement un des joix d'obtenir un tel unique motorcycle. Merci encore une fois de prendre le temps de me repondre.
Meilluers voeux, Lee

Yes. Some great advice offered. I was unable to purchase a 70mm pulley anywhere and ended up having a friend of a friend machine one for me. Fitted the pulley and smaller belt  on Friday and it's working a treat.

I used to dislike kickstarting the NF, particularly since I injured my leg trying to kickstart a very recalcitrant Royal Enfield before Christmas, and the dynastarter has transformed the bike .

Thanks everyone

Just a quick Dynastarter update for anyone thinking of going down this route .........I've been using for a few months now  and I have to say that I'm finding that the benefits really do significantly outweigh the problems I had setting it up - kickstarting the bike was a big chore for me - 'wrong' side kickstarter plus a bit of pereneal nerve damage in my right leg from overenthusisatically trying to kick start a very reluctant Royal Enfield a few years ago makes kickstarting anything more than  a few kicks a little uncomfortable  , so I used to hate kickstarting the NF.

All the parts are pretty easy to purchase - I'd say that the biggest hassle was the pulley, as I seemed to need a smaller pulley than I had anticipated, to ensure adequate charge.

Having to kickstart the bike was a major downside of the bike for me -I used to particularly dread stalling it lights or junctions- as this entailed pushing to the side of the road, putting it on the main stand and then kicking it over - these days , apart from trying to not to stall the bike , if I do , now it's not a problem .

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.

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.

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

Wotcha.

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?
