I have to decide which disc to put on the front of the 2C/375. One possibility is this weird item which came with the Forgotten Error donor bike. It's drilled. Never seen that on a Morini before. Also pretty rusty. Rusty beyond re-use? http://www.ps-fisher.demon.co.uk/pickchurs/disc1.jpg -- +-------------------------------------------------------------------+ | Pete Fisher at Home: | | Voxan Roadster Yamaha WR250Z/Supermoto "Old Gimmer's Hillclimber" | | Gilera GFR * 2 Moto Morini 2C/375 Morini 350 "Forgotten Error" | +-------------------------------------------------------------------+
I doubt it. only way to be sure is fit it, use the brakes a few times to clean off the surface rust and test the effectiveness, and take it from there.
I've seen the rusty part before, mainly when someone machined the chrome off the friction surface to improve the brakes. Not sure why they thought it clever to cross drill the rotor though, given that this tends to lead to more problems... I've seen disks that were a lot worse (Guzzi csst iron ones, for example) that cleaned up pretty nicely after the brakes were applied a few times.
Looks a tad pitted to me but no obvious cracks. It should clean up with a bit of effort but the braking will not be quite as good as a nice flat one. A few thousand miles with sintered pads should wear it a bit flatter.
Someone on the Morini list pointed out that the holes were not only probably too small to be of much use, but as arranged likely to cause grooves in the pads. Might give it a go though as it would save having to drop the front wheel out of the Forgotten Error to retrieve the disk from that. -- +-------------------------------------------------------------------+ | Pete Fisher at Home: | | Voxan Roadster Yamaha WR250Z/Supermoto "Old Gimmer's Hillclimber" | | Gilera GFR * 2 Moto Morini 2C/375 Morini 350 "Forgotten Error" | +-------------------------------------------------------------------+
