Dave, are you going to have New Church make your seat?

Yep, I'm going to have Ginger do my upholstery. Bringing the seat down next week while I'm in PDX on business.

Cool, glad to hear it. What are you doing for a seat pan?

Whatever she recommends. I'm the furthest thing from an expert in this matter.

I'll have video soon, but we had a few moments of sun in Seattle today - so I took it out on the road. It handles and brakes really well, and when it gets on the cam... it lofts the front wheel and races toward red-line. It's also luggable, uphill at 3500rpm in 3rd gear with no complaints. No, you can't whack the throttle open at that rpm, but a quick shift to 2nd and you're off to the races.

Things that need work include the position of the shifter and the figuring out why it's so hard to find neutral. The GP shift pattern takes getting used to as well. At virtually every stop sign I upshifted (pedal down with GP shift) instead of downshifting. At least once I downshifted when I meant to upshift.

More to come...

looking foward to seeing her out on the road
great build

The seat is now officially in Ginger's hands (New Church Moto) and should be done by the time I leave Portland on Wednesday. One more thing to cross off the punch list.

Pics of that asap, I can't wait to see what she does for ya. What did she say about a seat pan?

Glass from the Past is doing a fiberglass (shocker!) seat pan. As for what it's going to look like, I told her to do whatever she did for you (inch and a half quilting) as yours looks great.

A couple of new photos. Waiting for the upholstery and tidying up wiring. Also doing some little post ride adjustments.

The shifter and rear brake lever were both too low. Raised them, much better. Also the shifter is a bit too far in and a bit too long. We'll fab a new shift lever to deal with that.

20 weight suspension fluid was too much after welding shut the rebound holes in the damper, but compression and rebound damping were pretty balanced. In went 10 wt fluid, now it's much more supple, but could probably use a bit more preload. Rear shocks are perfectly valved.

The bike really feels small, light and agile underneath me. Big difference from how it looks and feels rolling it around the shop.

Somewhere north of 5k rpms, power does come on a bit like a two-stroke. It takes getting used to.

Welcome to the build and thank you to you both.

I guess a quick update is in order.

She's now carbless as I've gotten rid of my CR29's and am waiting on larger carbs. There's a set of CR31's headed my way and we might be on the dyno again middle of next week. Fingers crossed. I'll try the RS34's after that.

Pulled some more wire, but can't go any further until Ginger gets back from Mexico and finishes my seat.

As the seat is still in Portland, my pinstriper is at a standstill. (bah)

I did get around to ordering my brake lines from Spiegler. It'll be nice to button those up for good.

Painted the center of the rear brake rotor, and took that opportunity to make sure the install the final fasteners for the torque-link, exhaust, etc. Found a much nicer axle as well, as the one that came with the bike looked like someone had use it to hammer tent pegs for Ringling Bros.

That's all for now.

Dave

Great thread and I just spent last hour looking through last 4 pages - amazing information and attention to detail - really like the orange metalflake - very very cool. I checked but couldnt see it but what shocks are you running on the rear and do you like them?

thanks and good luck
Andy

Andy,

Thanks for stopping by.

The shocks are billet-trackers from Works Shocks http://www.worksperformance.com/html/street.html They're custom valved for each application, and I had them made an inch longer than stock at 14.25".

Combined with the standard swingarm upgrades, the shocks are doing their job very well and I'd recommend them to anyone.

Doctor_D · « **Reply #291 on:** May 22, 2011, 08:53:16 PM »

RS34's are installed, but not without drama... Boiled carb boots in wintergreen for a couple of hours, chamfered the edges of the carb side and it still took three men, a two-by-four, and a goat to get them on.

OK, not a goat but a strap, grease and some not-so-gentle persuasion.

Anyway, they're on. Fired it up before I had to run home. Different sound and starting sequence than the CR's. If I didn't know better, I would say it was quieter.

Finally, think I need a warning sticker on the bike, "warning: birds and small children keep back five-feet." Why? Look at those velocity stacks... one could easily lose a pet in there.

Hoping to get a dyno session in this week, but busy with a new job and a new house at the same time... We'll see.

jaguar · « **Reply #292 on:** May 22, 2011, 09:07:49 PM »

really want to see some numbers from the dyno.
those carbs are HUGE!

Wow I didn't think it would be that hard. I.am curious to see some numbers!

What's up with your seat?

My seat's on it's way back from Portland any day now. Seat pan and foam are done.

Shooting for Mods and Rockers to officially debut this thing. Clock is ticking...

tweakin · « **Reply #295 on:** May 23, 2011, 07:00:23 AM »

Looks great Dave! I am strongly leaning towards those carbs for my 915 build. I look forward to hearing your results. You better have that thing ready for the mods vs. rockers ride, should be a great time.
