I'm pretty sure he has a day job. Probably something came up.

Bump

Hmm maybe he could do with some more donations so he can work on his bike instead of having work on other people's stuff.

Well, yeah, Chris has had some hard luck as of late. His car was stolen a few weeks back and wasn't covered so hard financial times probably got a lot harder and it's probably tough to do updates considering the situation. I know Chris and he's a fighter but when your ride is stolen it's a real tough pill to swallow. My motard was stolen a few years back from the same place - it just sucks.

He'll be back though - it's not the first time his car was stolen...

Thieves suck. Remind me, why did we stop hanging horse thieves?

Because the world got all "PC" and civilized. we could solve a LOT of problems if we were to go to the ancient times of "eye for an eye"

wow, its been a while

Sorry to drop off like that guys but the holidays started the diversion, then some work came in, then the universe decided to piss on my neck and tell me its raining again. Yes, car stolen always sucks. It was recovered with no tires, crash damage and no steering column so I'm not sure if I should be happy or not! the silver lining is that it is a Subaru and there is a lot of aluminum in it that I can sell to the scrap metal guy! Anyone need a 2003 WRX driveline? 68K miles runs great.

At least the work that came in is interesting, it is converting the cast crankcases of a Yamaha TZ250 GP racebike to billet because of bearing insert and general availability issues. I just put a post on the blog site but here's a couple of images. The parts are pretty damn sweet if I may say so myself. So far these 2 parts produced 1 55gallon barrel of chips in addition to some bandsaw stock removal.

The project is for Bruce Lind, a 250GP addict who still runs them all over the West Coast. He saw the V4 project somewhere on thew web and figured I could pull this off too. A couple of emails and phone calls later and I was on my way. a few months later and we're almost ready to assemble and test the first set of cases. Once they are proved out I'll make 10 or so sets for him. If anyone is in the market for a set contact Bruce and go from there. On the other hand, if anyone needs a part, engine, or bike reproduced then give me a call.

















Once I'm done with a few more machining operations and a test assembly I can shift focus to the V4 project. I think the swingarm was the last post so next one will discuss the hows and whys of the chassis design.

I definitely will not let another gap like this one happen. Sorry 'bout that.

And thanks again for all the donations. T-shirts will be shipping out shortly to all. And the blocks will be going out for Nikisil plating!

That's it for now.

whale rider,

Designing the output shaft and swingarm pivot to coincide would reduce chain tension issues but it is a serious packaging challenge to make a clean design. It also complicates sprocket and clutch plate changes, something that happens frequently on a racebike. The tension variation issue not that big these days as the use of long swingarms and short sprocket to swingarm pivot distances reduce the tension change to a small amount. On non-unit engine designs (vintage triumph and nortons, etc.) the tension variation is huge but its not so much on modern designs. Another factor is that my use of idlers to control squat behavior results in even less chain tension variation than a standard arrangement. The bottom line is that a small amount of chain tension variation is not a horrible thing so if you can easily eliminate it fine, but if it is a bear to eliminate then its not a big worry.

As far as the steering damper position goes, the steer links and pivots from the 'handlebar' pivot to the upright pivot are pretty rigid so it will do a fine job where it is. If it was on the upright it would add a small amount to the sprung weight and further crowd a small critical area.

>>I wish I was a millionaire and could get involved in this sort of thing.

That makes 2 of us! ;)

Oh, yeah? Well I changed my own brake fluid!
This is great stuff, Cosman. Thanks for sharing!
