Identify Bike from motoscrubs photo page

Now the next question. I realize some people use the narrow and widecase as daily drivers and each has there own issues.

In terms of reliablities other than the kickstarting issue on the engine case is there anything other than the increased oil capicity that makes the wide case better for a possibly daily rider? Or should there be known issues that I look for/reference to a seller?

the bike Phil photographed is a SCD . the riding testbed for the Desmo engines

D'oh! That's what I get for not paying attention, He clearly labels it as an SCD too.

As for the build numbers, Frank also thinks there were only 6 350 SC's built, the rest were 250s.

What is the clear line off the tach drive for?

Looks like an automatic chain oiler to me. Takes oil from the tach drive and lets it drip onto the countershaft sprocket

There is one of the six 1965 350 sc factory race bikes posted on ebay UK...wish I could attach the photos - can somebody catch the pics, as well the description is quite informative. Magnifico !!! pr

Thanks for the photos Bob. That 350SC is to be auctioned next week at Brooklands - the bike seems to have also been auctioned there a few years ago. Would that paint scheme have been the original colours ? Not sure what the chrome link under the left swing-arm to the rear hub is... The bike has some fine features-some of which are probably not so apparent to me, and some aspects like the oil returns require further understanding. I am intrigued by the dual-spark set-up as my favorite bike is a 06-SS1000DS, it has excessive grunt! Opinions on dual - spark including Nigels' testimonials suggest some low-end torque increase but some issues at revs ? pr

The linkage under the left side swing arm is the brake backing plate anchor link. On production Ducati singles the backing plate has a slot that is engaged by a steel block welded to the swing arm.

This is a cheap way of stopping the brake backing plate rotating, but has the disadvantage of feeding the braking torque into the swing arm and causing the rear suspension to squat when the brake is applied.

The (near) parallel linkage shown in the photo acts as a tension member taking the torque induced by the braking and transferring it to the frame, without having much effect on the suspension action. This is a better setup for a racing bike where the slight extra cost is not important, but handling is paramount.

I have just had a look at the second photo and I must retract the bit about transferring it to the frame; but only in this case. It can be seen in the second photo that the link is actually attached to brackets off the bottom of the swing arm, and not the frame as I assumed (from just looking at the first photo).

The machine in this photo still 'has the disadvantage of feeding the braking torque into the swing arm and causing the rear suspension to squat when the brake is applied.' It has the slight advantage that a bending moment is not applied to the left swing arm member by the direct 'keying' of brake backing plate to the swing arm though.

My last two sentences should be amended thus:

''A better design is to have a linkage parallel to the swing arm, that acts as a tension member, taking the torque induced by the braking and transferring it to the frame. This design does not have much effect on the suspension action. This is a better setup for a racing bike where the slight extra cost is not important, but handling is paramount."

I probably should add:

The brake backing plate and both ends of the link should be allowed to rotate as the suspension movement will cause the swing arm/link geometry to vary between rectangular and parallelogram.

I started in the same spot (sort of). I had my dads scrambler in need of restoration. I was going to go stock as I have every single original piece and doc's to match. Then I saw Carl Liebolds Mach 1 restoration and I was going to go that direction. THEN I saw the grey bike from this site and the orange racer on the site as well. I had to go Café after that. I really like the style and it was / is a good project. Being as I did not alter any original parts, I can always go back to 100% stock scrambler if I needed. For now I like the Café style. Scrounging parts for a 450 Corsa replica now. Talk to Malcomle at Syds Cycles once you locate a bike. He was really great help on my motor work and is a good source of information as well. Good luck on your search.
