Re: Bottom end strip

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.
Regards,
George

Seat trim screws

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 ...

Re: Indicators

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...

Refitting bezels

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 ...

Re: Replacement Fork Tubes

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: Refurbishing carbs, what parts wear

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...

Re: Front sprocket for 3 1/2 Sport

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...

Re: Front sprocket for 3 1/2 Sport

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.

Re: Convert choke to bar mount lever

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

Re: gearing

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...

Re: A question of forks

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...

Re: oil dipstick position

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 ...

Re: Noisy clutch?

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!
