Jim's Speed Twin Build

Not really part of the speed twin look, but I just love those fishtails... :heart:


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.
A question I have been meaning to ask. Are any factory cams hotter than others? More lift, more duration?
 
Picking and choosing engine components from various years is "true" hotrodding and old skool kool!
A close ratio early gear set would fit that bill also. First gear is higher in the 70 tranny, while late model shift drum cam followers should offer easier shifting. No idear how well you can mix match some of those parts. There is an early/late gear/shaft incompatibility with the change over somewhere around 75?
 
Interesting cam work and nice to see pics of it. It's something I'd like to try. You said you researched the operation but did you see this post by mrriggs? Yes, he presses the sprockets off but doesn't recommend pressing them back on because you can damage the cam, run the risk of cracking it. Instead, he uses heat on the sprocket and that allows it to drop right on. You even get a few seconds to adjust it so it's aligned just right before it cools. See post #5 here .....

The crack in his pic looks to me like it was caused by too much force when it was pressed back together... and I suppose that would happen pretty easily if you were to give the press an "extra" pump after it seated. My process was to keep a close eye on the gap. As soon as the pump pressure changed (increase), I stopped and looked closely all around the sprocket to make sure it was seated. Satisfied it was I stopped and called it good. I'm 100% confident I didn't cause any cracking.
Having said all that, I like the idea of heating the sprocket and having a few seconds to fine tune the alignment. I think I'll give that a try if (when) I have to move the sprocket.

It's a little odd that thread never turned up in my searches... or maybe I overlooked it.... dunno. :umm:
 
One other option would be to use dry ice or liquid nitrogen to cool the camshaft.

But if heating gear or cooling cam I would still be temped to use a press of clamp of some fashion to hold the two in position while the two parts equalize temperatures.

Used to assemble planetaries for off road transmissions using one or the other method, cool pins or heat housing. As long as no one interrupted you in the middle it was a easy and fast method!
 
The SG build is winding down. The only major item left is making the the forward pegs and controls... and I'm still ponderin' on how to do that. I'll get it legal this coming week and put some miles on it while ponderin'. So.... time to start the next one. Here's what I'm starting with....

It's an eighty something special frame with a seventy something engine. The engine even has compression on both cylinders. I've got 2 more engines so, this may not be the one I go with. Still working out the details.
I've had these down in the shed for the past 6-8yrs....

XS1 wheels and brakes that are in pretty good shape... very little rust on the chrome.

During the SG build I made a rotisserie frame jig. It made painting the frame a lot easier.... but I was always building the jig for this project... and the next...:rolleyes:

So.... drum roll please.... here's what I'm going for... a late 40's early 50' Triumph Speed Twin look.

Or maybe even this.....

After a year and a half of a restoration and all the detail work that goes with it, I'm ready for a build project that allows me a little more latitude on where to go. Should be an interesting journey.
I had a 55 Speed Twin, nice bike. Loved it with the Amorath Red paint job. Keep us poster on how it goes.
 
Dad had an Evinrude Speeditwin 15 HP :cool:

Did bit of research and I lied, it was a 14HP Fasttwin.
Zactly like this one
OK sorry to interrupt this fine thread.

OMG. You guys make me laugh. Looks like that Corvair (1960 or '61? ) had a trailer hitch! A pretty elusive installed option for a Corvair for sure.
I'm laughing because for at least a year I had my wife carry around a hammer to get the starter going on her 1988 VOLVO 240. She had that car from 2002 (when we sold our '63 Corvair Monza coupe because she would not drive the stick) to 2012. The hammer trick was not well received around 2006 when she was carting around our 3 and 6 year old boys. It does make a great story now though!
 
What's that in the garage? Corvair?
My mother drove a 1961 baby s*** green corvair. She hated that car she despised it. As Houston was designed to do after a big rain our street flooded and as a 6 year old I was up to my tits in stormwater out in the street. Saw my mother pull up at the end of the block looked at the water backed up a little bit and gunned it. She had a new car the next day.
