Brooks and Wemoto advertise Tarozzi fork tubes - I got mine through Wemoto. Morini may well not be listed, but Ducati Pantah probably are, and they will fit. I have these on my Strada. Just beware, in my case I found differences between my '78 fork internals and top caps when compared to the later (...

Re Flat Spot. Firstly, the Sport is significantly worse for this than a Strada due to the cam overlap. I can't recall my sport having a flat spot when it was new, perhaps it was the way it got ridden I never noticed? Fast forward 20 years and unleaded fuel, and perhaps a more relaxed riding style in...

Hi Ross, If you go the '520' route, you would need a new rear sprocket as well. For your info, the numbers for the chain refer to the pitch (distance between rivets) and width (where rollers are) in units of 1/8inch. E.g. a'530' Is a 5/8" pitch, 3/8" wide chain. A 520, being a 14" wid...

Yes. Standard is a 530 chain.
Your choice, but a '520' chain is a sensible option- means you can run o-ring chain.
You probably found out, but the rear sprocket standard is 38 teeth.
Regards.

Never done this 'mod' and personally haven't seen the need to, but others have felt the need and have done this.
My understanding was that Guzzi V50 (which had VHB carbs and a handlebar mounted choke) parts were used, so someone like Gutzibits might be able to help you.
Hope that this helps,
George

Hi, While acceleration in top is nothing to write home about, it should be a usable gear. I had a similar problem a few years ago, and it turned out to be that the rear cylinder ignition was not advancing. To check this, you will need to add a "PMS2" mark on the flywheel - measure distance...

There is no setting as far as I know. Have always assumed that it acted as a one way valve such as let's air out when forks compress, but stops air going back in. In 45 years ownership, I've never even thought of 'why' until your post, but I suppose it might have a technical benefit of keeping oil i...

Hi, Can I put in a 'plug' for a 'fork oil seal removing tool? The alloy at the slider tops is rather thin and can easily break/chip if you aren't very careful. I use one like this. https://www.ebay.co.uk/itm/174486346138?var=0&mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338990947...

Hi Fully in is the way I've always done it. Top mark on my bikes corresponds to measured 3.0L oil put in after an oil change. Mine are 1978 bikes with the overstamped bit in the riders handbook saying 3 litres instead of 2.5, so it was many years later (probably after 20 years!) that I saw that the ...

Should you take the spring retaining screws out, when you reassemble, add some copperslip/neverseez onto the threads. Don't overtighten them, whatever you do or they may never unscrew again! If anything, it is better to leave then 1/4 -1/2 turn from fully home. They do stay put, honest!

It is normal. 350 and 500's run dry clutches so are much noisier than a comparable Japanese bike. Try listening to a dry clutch Ducati or a 1970's Yamaha TZ if you still think it is loud. The clutch is noisier when disengaged as the plates have room to move around. As long as a/ it doesnt slip, and ...

Hi,
I think you will need a 6 wire one. From memory the switch connects the side lights for normal riding as well as parking.
Have known to be wrong though.
George

Try cleaning all connections on the green wire between generator and transducers and try it. Leave it off the ignition switch as an extra measure. I will say 9v sounds very low, so am wondering if your rotor needs remagnetising? Other things to check: Resistor plug caps? Resistor plugs? Either/both ...

Tom,
Have sent you a pm.
