Wire colours from memory. Blue = ground/earth Grey = tacho signal feed Brown = switched 12v Green/yellow = light feed for smaller lights ( speedo/tacho illumination, side light and tail light. It would be worth your while getting a copy of the wiring diagram . There are good colour versions on the m...

Sounds correct. It suggests yours is one of the earlier style with a red light to tell you that the ignition was on. Not unusual to have no bulb as the red could be annoying when riding at night. If there are a pair of wires "loose" near the socket (brown=switched 12v, blue=ground) that wo...

Hi, Pantah ones can fit straight on, but it depends on what year your bike was built. My '78 Strada has them (Tarozzi) and they are good now, but I had to make up various spacers to make them work. Others have fitted them without issue as they were the same as their old ones. To me, they are well ma...

Hi. Alternator output on earlier (pre electric start) 350's was only given as 100W - and no data was ever given as to how many revs were required to achieve that. Add in age, demagnetised flywheels, poorer connections, ridiculously thin wires in the switches etc, then they will struggle. For what it...

Hi Oli,
In answer to 1/, you need to undo the two cap head screws in the clutch side of the crankcases.
2 and 3 are as Mickey says.

Hi All. Does anyone know of a cheaper source of the tiny screws that hold the aluminium trims to the sides of the seats on pre 1980 bikes? The nearest I've found is from BMW - see pic- SeatBolt319-2T.jpg and they charge £2.40 each for them! That's a lot for an M3x15 screw to me, especially when you ...

Hi Paul, I have these indicators on my Norton They are well known for earthing issues if using the casing/stem only. You should find that there is enough room to feed a second wire down the stems on them. Terminate the end inside the indicator with a small ring and fix to by one of the bulb holder s...

Hi Mike, I have had my Norton's 'Smiths' rev counter rebuilt and when refitting the bezel, the guy doing it used a lathe! Very cleverly mind you. He held the speedo body in a fixture in the chuck, a large 'pad' in/on the tailstock was used to hold the bezel in place, and a tool with a small bearing ...

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...
