Re: 1966 250 Monza => 350 Bitsa

Three years is nothing- would rank as a 'current' project to me, but, to your 'what an unfinished project is worth?', question, the best way to find out is to put it on Ebay and see where the market values it. I expect you'll be disappointed- unfinished projects aren't highly desired- you've probabl...

Re: 28tooth cam gear dimensions

After thinking about these gears a little more, the factory only offered them as a pair, so the different part numbers were probably the different lengths of the tower shaft, and the 28t camshaft gear is probably the same in the 250/350/450 gear sets.

Re: 28tooth cam gear dimensions

Jack, I can offer some info- The attached photo shows, left to right, a round case 750 twin gear, an unknown gear, and a narrowcase single gear. The middle gear was on a narrowcase tower shaft, with the snap ring- the way I and others usually save these gears to keep gears with matching grinding mar...

Re: Manifold for Dellorto PHF 32

Jack, I'll attach a photo of a manifold that would meet your specs- the 750SS and 900SS have 58mm stud spacing- the 750GT and 750 Sport have the 52mm spacing you're looking for, but the GT and Sport front manifolds and GT rear are the elbow style, so you want a Sport rear manifold, like this: sport....

Re: 250 Monza Project, might build a mini Super Sport

An old brake with glazed, hard shoes and a rusty, out of round hub probably won't stop that great, but if rebuilt it will work fine. The 2 sided single leading shoe brake isn't that much of an improvement- the photo shows that the shoes are quite a bit narrower- the gain in friction area isn't as mu...

Re: Narrow Case AC vs DC coil

The primary coil is between the 2 battery posts- probably marked '1' and '15', and the secondary is between one end of the primary and the spark plug output. The battery '+' usually goes to '15', so measure the primary between '1' and '15' and the secondary between '15' and the spark plug output. De...

Re: Mach 1/Mark 3 front fender info

David- I'll attach a drawing of the profile of a fender I believe to be a Mach1- I didn't buy the bike new and keep an eye on it ever since, but it looks correct to me- no guarantees. Fenders I've seen all have the front edge turned- without the turned lip the edge would be really fragile- the lip g...

Re: Tweaky Beast History

You're the right owner for that motorcycle- lots of people would have ignored it as a mongrel 'bitsa'- have fun with it.

Re: Reground desmo cam

I'd say you're right to question the workmanship. They may have used a probe to digitize points on the cam, and then just drawn straight lines between the points instead of interpolating a curve, or they might have good data on the profile and their software broke the nice curve into small segments-...
