Re: no one run Pirelli Phantoms?

Do the Bridgestone and/or Avons run tubeless on the older rims?

Re: no one run Pirelli Phantoms?

Thanks Tim. Phantoms were original rubber for the 81MHR from the factory and they look so good but I guess the times have changed. I can't find the same sizes I used to run on. I just peeked at the Bridgestone BT45, they look pretty good. What sizes do you run on the 750? I see you've been busy on t...

Re: Removing rear master Brembo piston - need help

Thanks Craig: I managed to get the piston moving back and forwards under its own spring pressure (sometimes) last night and left it soaking in penetrating fluid. Got to find a bigger drift! I decided to leave the cup as-is and clean around it. What is it that hold the thing in place? Just an extra f...

Removing rear master Brembo piston - need help

Hi all: I'm pulling my 81 MHR apart for an overhaul. I took the rear brakes apart today; the master cylinder piston has been jammed for years (bike's been off the road 28 years). The only parts I cannot remove is the master piston and the plastic cup! I have a flat head punch that was just the right...

Re: Neutral switch paradox

Understood norvilbob: I posted the picture for you to see what it looked like on the later models should you wish to copy it if this is even possible. Your box may not have the necessary parts to do this. I just found my redundant side stand wiring today!

Re: Neutral switch paradox

My 81 MHR has a "Side Stand" lamp that is non-functional as there's no side stand!

Re: Neutral switch paradox

Norvilbob: My old 74 GT860's neutral switch was in the right hand side rear casing where the gear selector mechanism is located. There was a small brass cam that pressed against a switch when in neutral as wdietz186 mentioned. In the picture you can see the brass cam. The switch threads into the hol...

Ducatiwerkstatt Drewitz, highly likely Georg Drewitz who I think is the guy who did the work on your bike. Worth a try calling the phone number in the link.

Re: Drewitz full flow oil filtration.

Interesting set-up; mine's only half way. I found this on the Internet, same as yours: http://anthonygodin.co.uk/car/ducati-mhr/ It looks like a really clean system. Is there a cooler somewhere? What does the filter look like inside the Drewitz casing? I'm trying to work out how it works from pictur...

kick lever crack

Bad design...

I just found this the other day; a hairline crack on the thinnest part of the kick lever. Has anyone tried a weld repair? There's not much metal to work with:

Re: 81 MHR lower fairing brackets!

Planning to do the same myself! I found some pictures on the Internet last night so I have a better idea of what to make.

no one run Pirelli Phantoms?

Hi folks: Back in the 80's, many of us used Pirelli Phantoms; mine are shot and need replacing after being in storage for way too long. I've scanned the Internet and see that Pirelli still make Phantoms but I'm interested in thoughts compared to today's tires.
