Re: 350 crankshaft question

Hi Nigel, I've seen at least one NC single with the pin bore not fully cleaned up by the final machining operation. It came with an oversize pin marked "+3" from the factory and the pin bore was 27.3mm. Guess Ducati didn't want to reject the flywheels. I've seen these oversize pins as repl...

Re: 350 crankshaft question

Another caution: Flywheels have a countersink on the inside so the flywheel can be turned between centers. Check the countersink on the inside of the timing side flywheel for being drilled too deep and penetrating the oil galley. Found this on a Mototrans, probably loosing a little oil pressure ther...

Re: 350 crankshaft question

I agree that, to a certain extent, a pressed up crankshaft is a pressed up crankshaft. However, there is a distinction between two stroke cranks (which is what most shops who accept presswork will be dealing with) and four stroke crankshafts. Two strokes are typically solid, straight big end pins. L...

Re: 350 crankshaft question

On the east coast, there's Falicon and Syd's Cycles who have experience with Ducati single crankshafts but they're both in Florida. There must be someplace in the Northeast but nothing comes immediately to mind.

Re: Tom Bailey Singles Masterbook

Adam, it sounds like you’re referring to the masterbook/workshop manual. The factory manual being un-copyrighted material, Tom Bailey has issued a reprint in the masterbook. Probably 90% of the publication is the factory manual, wiring diagrams, specifications, a KLG spark plug cross reference, spec...

Re: 350 crankshaft question

Ducati crankshafts are not difficult to disassemble but do require some specialized knowledge and tools. If your machine shop does not possess these, I can understand their consternation.

What corner of the world are you posting from?

Re: GM Desmo Camshaft

Apparently, fitting this cam required opening up the cam bore in the head. Whomever did the machining went a little too far and had to weld up the hole for the head bolt. This head also has a modification to the valve guide. A short guide, something like a Pantah arrangement is installed (I've remov...

Re: Looking for a set of triple trees

170mm are the road race type Ceriani clamps. Most off-road Ceriani clamps are 180mm as are Betor clamps from Can-Am dirt bikes and many Spanish models that use Betor forks. The Betor clamps are, if not exactly 60mm offset, then within a couple millimeters. Ceriani off-road 180mm clamps have many dif...

Re: 175TS in UK

Parker Hannefin product, known as “Stat-O-Seal” in the US. But I‘m not aware of one narrow enough for use in this application. But could trim one down to fit if necessary.
