Hi Grimly,
most likely equal to the number of screws that were left a part-turn loose.

Yeah, it's been done several times before. Got a specific one in mind?Jim, it looks like someone has beat you to the punch on the Speed Twin build
I thought that too but somehow I think Jim's build will be more Go and less Show.
Not really part of the speed twin look, but I just love those fishtails...
Yeah... will be 750 kit with prolly an early 256 cam.... maybe more, but I'm hopin' for a daily rider as well as the old school look. I'll have the hardtail look... with a softail suspension.I thought that too but somehow I think Jim's build will be more Go and less Show.

While I was reading up on swapping in the 256 cam I ran across a thread talking about an adjustable sprocket.I wonder if anyone makes an adjustable sprocket for the XS cam? I assume so, but never looked.
Thanks.Enjoying reading this Jim and looking forward to more.
Um... been a day or two....
I've read from several knowledgeable folk here that the XS-1 cam gives a fair bit more mid-range grunt than the 447 cam. Not quiet a Shell#1, but pretty good none the less. Of course, I've no personal experience... but I do have a locked up XS-1 motor I been meanin' to tear down. Hmmm....
Turns out the cam is almost pristine.

Forum member @MrBultaco was kind enough to supply me with a 36T 447 cam that was a bit nicked up. Thanks Tom!!
Needed to press the 34T off the XS-1 cam and 36T off the 447 cam and swap 'em. So... Tool(ing) Time!
Drilled a half in. hole in a half in. steel plate and pressed in a half in. steel rod. Had to dress the rod a bit, but a nice press fit.

Made for a nice stable holder for the cams.
The teeth on the XS-1 sprocket split the TDC groove on the cam. The 447 sprocket lined up on a tooth. There's my reference point.

Time to press.

Both separated.

The backside of the sprocket has the punch mark for referencing against the head face. Counted 9 teeth from there and marked the tooth on the face up side.
With the aluminum tube sitting on the steel plate, I could rest the sprocket on it and slide the cam down the rod. This allowed me to see the pertinent marks for alignment. Once I was satisfied, I set a block of wood on the cam and gave it a few solid whacks with a hammer. Seated it "just enough" to flip it over and set it back in the Great Orange Beast.

Near as I can tell, I missed by about a degree. No worries, there's too many variables at this point.... head gasket thickness, cam chain length... and I still haven't compared the aftermarket 750 jugs with the stock ones to see if the height's the same. Once I get the motor back together I'll index the cam and see where I'm at. Might get lucky and hit it dead on the first time, but I suspect this is just try number one.
Ready to install... Into the box with the 750 jugs for now until I decide which motor I'm gonna tear down.

This whole year has been nothing but remodeling the house (keep Sue happy ), winding rotors and painting tins... with the odd bit done to the DT. Was nice to get back to the speed twin, even if it was just a simple job and an hour spent... I'm happy
