Spoke wheels on a 1981 900SS

I’ve managed to get gather most of the bits to put some spoke wheels on my 1981 900SS. I I have a complete front wheel with 4 bolt discs fitted. The mags are FPS, I have found a hub online that appears capable to accept either a 4 or 6 bolt disc for the rear. Has anyone out there done this? Does the ...

Re: Borrani rims

Alright alright I get the message..........haha. Thanks for the reply Baddean, not sure what happened there. I have that exact same issue if I send a friend an article off Quora via SMS. It will replicate it 3 times every time but only to him.
The wheel has long since sold. It was on FleaBay, was a ...

Borrani rims

Does anybody out there know the significance of the 4777 stamped on Borrani rims? I’ve got access to a Guzzi rim that has all the same numbers as. Ducati rim except instead of 4777 it’s stamped 4845. Is that just a number denoting the marque it’s going to be fitted to?

Re: Marzocchi damping rod Race Tech emulator

I did this modification about a year back on an 860GTS with Marzocchi forks but mine were assembled differently.
The piston on mine was pressed onto the top of the rod.
Basically all I did to mine was remove the piston and machine the centre out and sit the emulator on top of the piston. The rod ...

Re: Hesitation on throttle opening

Many, like about 30 years ago, I had an acceleration issue with my 860GTS. If memory serves, and it often doesn't these days the issue was the same as you speak of with a hesitation when the throttle was opened. I`m pretty sure I put it right by putting slides with a different cut away in them that ...

Re: 78 Darmah Silentium vs Conti mufflers

Although I have never heard Silentiums myself I believe thats the whole point of them. They are quiter and might might cost you a bit of power too. However I, and many others, have always found a bevel drive singing through a set of Coti`s to be a beautiful sound. Change your neighbours not your ...

Re: Removing spokes from front hub - 750 Gt

Apply a bit of heat perhaps. If you have heat gun, hold it nice and close to the alloy next to the spoke. When the ally is to hot to touch tap the end of the spoke with a hammer. If your not re-using the spokes cut them fairly short so you can tap the a little harder.

Re: Clutch Grabs Violently on Fresh Engine

Did you get this issue sorted Herbg? Interested to know the outcome as I will be fitting a new clutch to my 860 in the future and was thinking of the 1425 Surflex upgrade. Still wondering if to re-use my metal plates and just put new fibre plates in.

Re: Hi from Switzerland!

That my friend, is the offending cap screw. I was about 2 hours from home and began to get gear shifting issues. Finally I got it into 3rd gear but I could not shift it further. I rode about 15 kms like that to a service station and managed to shift it into 5th gear while on the centre stand. I was ...

Re: Hi from Switzerland!

Not sure of the time line of the selector mechanism`s of bevel drive Ducati`s. What I do know is that the selector mechanism on my 82 SS is nestled behind the the clutch drum. I had an instance when the cap screw (from memory it was counter sunk) that held the fork had come loose. It caused the gear ...

Your a little short on info regarding poor running. Someone once said to me that most carb problems start in the ignition. That is, carbs are often blamed for ignition issues. Have you checked carb balance? Comprehensive run down here: http://forum.bevelheaven.com/viewtopic.php?f=26&t=10

Re: So close, 81 MHR

I`m building a bit of a cafe racer special based on my old 860. So far I`m only at the parts collection phase which has been going on for some years now. I`ve set myself a goal that I have to finish an old 1952 Panther that I`ve had for some time. It`s been a very difficult Reso. Parts for her were ...
