  thanks for that!

Bitchin' cool Mark 

Oh, hell yes!

I stopped into my favorite local bike shop today...



Not something you see very often anymore!

So cool, Colin! That bike has turned out so well...you're a hand grip away from being done! Anxious to hear the first ride report.

Had the opportunity to buy one for a song 20 years ago, but I was young and foolish and passed. I feel old and foolish now. Beautiful bike!

That's good livin', keep it up

Seems like it would lengthen the intake tract...

  great graphics, and your front disc looks ferocious! Very nicely done.

Finally ready to ride! Trued the rear wheel this afternoon and we took some shakedown laps this evening. For a diesel, it rips! Lacks low end compared to my KTM, but likes to eat from midrange on up. Scared the youngest boy a little, which is my fault for letting him ride a quad for so long.



Forks were harsh at 16 clicks of compression; I liked 12 so much better that I set them at 10. Dunlops are rounded and both ends slipped around a little on the grass track (pasture), so some new rubber is on the agenda sometime soon.
But first, the boys and I are taking it to the Gifford Pinchot nat'l forest/Saturday for some easy trails. Buddy Ron, with whom I rode last weekend, is coming along and may bring his brother. I'll try to get more pictures this time!

$800? If you love it, I say road trip, Czakky!

I'll be corrected if I'm wrong, but it's about sag, "static" and "race". Surely there are othe terms, but static sag is how much the suspension compresses under the weight of the bike, such as when you take it off a stand. Fully extended-off the stand but supported from falling over=static sag.
Then sit your fully geared butt on the bike and have a helper keep it from falling over. This amount of compression is race sag. Static sag-rider on the bike compression=race sag. Fork compression easily measured by putting a zip-tie around the tube and letting the dust wiper push it. To measure the rear sag, pick two fixed points such as the rear axle and a seat bolt. Here's where you might need a 2nd helper, as you're occupied sitting on the bike sweating in your riding gear and helper #1 is keeping you and the bike from falling over.
How much? Well, I've seen 25% of fully extended length recommended for race sag, and different linear measurements listed for specific models. I think Fox said 1.25" for their shock on an RZ350. What you're trying to do is achieve both your target static sag AND race sag. If you can't, you need a different spring, like if changing spring preload to get the desired race sag screws up your desired static sag.
That's all good fun and a nice exercise, but alternately, you can weigh yourself in full riding gear and call Race Tech or another reputable spring vendor and they'll recommend a spring weight. They're probably most forthcoming if you make it clear that you're calling to place an order!

I've got a chainsaw engine that's doing a whole lot of nothing at the moment...and a go-cart chassis. Wait, that's four wheels...I'm out!

I'd love to meet the owner, stand in his driveway while perhaps nursing a beer and look down at that compelling thing to hear his story. And then yes, once down the airstrip! Maybe twice. Probably should make that a celebratory beer afterwards.
