Upholstery is complete. Like every part of this project, took longer than planned, but it looks good.

Gotta wire the tail/brake light, build a license plate bracket and wrap the wiring harness. Finally, I need to get the tinwork pinstriped and clear-coated in a reasonable amount of time as the clock is ticking to Mods & Rockers.

Hi the bike looks amazing. I was curious how is the seat vinyl attached to the seat foam? Are you running some sort of seat pan?
thanks!

Stay:

I'll take photos when it gets to me. In the meantime, Branden's thread has a seat made by the same person and some great pictures.

Do you have part numbers for your wheels? I want spoked wheels to replace the Comstars on my 78. Also what rear shocks are you using?
great build!!!

Looks good David! You better get to wrenching and tuning if you plan on June 4th as a finish date. You will be cutting it close for sure. Especially with all of the other things on your plate at the moment. Let me know if you need help with anything, I would be glad to lend a hand.

Stay,
My seat is very similiar to David's. Ginger at New Church Moto used some sort of "burly upholstery adhesive" to secure the vinyl to my seat pan. Normally I would not be satisfied without some sort of mechanical fastner holding everything down but she knows what she is doing and I am convinced it will hold over time.

Hi Branden I was lookign through your build and your bike looks great. I did notice that it was adhered by adhesive to the metal pan. Looks great. Might do something similar.

sorry to hijack!

Thanks for the offer. Might take you up on it.

I forgot to add a rear fender to my punch-list. I've got a temporary one held on with zip-ties, but have to figure out how to mount something more permanent. This is made harder by the fact that I cut down the frame and don't have many mounting options.

Thanks for stopping by. Almost all the product info is in the thread if you're curious. But, to save you a few minutes, the wheels are composed of polished stock hubs laced up with stock-size Sun alloy rims and polished stainless steel spokes. I did the polishing. Lacing, etc done by Buchanans in California. They do great work. Use them for all of my projects.

The shocks are 14.25" long Works "Billet Tracker's".

So do you just braze over your welds to smooth them out, instead of grinding them?

brandEn · « **Reply #309 on:** July 22, 2011, 04:10:24 AM »

Dave? You in there? Whats going on with your project?

lucky · « **Reply #310 on:** September 24, 2011, 05:00:13 PM »

I have never had a problem with the phillips screws. Just use a #3 phillips but on a hand impact driver.

Do not use a #2 bit or you WILL ruin the screw.

So, the new house and new job have settled just enough to allow for some work to get done.

Dyno runs were posted on the Hi-Po board a few months back, but I'll put them here too. The switch from CR29's to CR31's was uneventful. Picked up a few horses. For reference, stock 750F was about 10lbs/hp -- this one is 4.9lbs/hp. Until I have a solid weekend to play with the RS34's, 84.76 rwhp will have to suffice.

Wiring harness is complete and taped. Small, light, and simple. Lots of little changes, improvements done before it was taped up. Baja designs left-hand switch cluster does everything I need it to and more.

Rear master cylinder reservoir is installed, brakes bled, brake light switch wired up, etc.

Here's the bike, assembled and ride-able -- with one PITA exception. Excuse blurry camera-phone photos. Tins are finally pin-striped and clear-coated.

The exception has to do with my oil lines and is a self-inflicted problem. I relocated the oil-tank about an inch inboard, which made it line up nicely with the frame. Unfortunately, left the angled oil inlet pointed straight at the motor. Too tight a radius for the braided lines I had made. Working on a fix, but given my lack of time it may slow things down more than a little.

The remaining punch list is aggravatingly short:
-license plate bracket
-rear fender
-fuel line and filter
-maybe figure out how to baffle the exhaust.

Looks good. Did you remove the chainguard mounts? It gets tight in there, I currently have a 54 t rear sprocket, had to notch the guard severely..

Yes, the chain guard mount are gone. No plans for a guard.

Very Nice looking ride Dave. What happened to the RS34's mate..?

I still have them and really think they're going to be a nice addition to the project.

The reason they're not on the bike now it that my RS34's have a weird problem involving a random cylinder running cold and lean or not running at all. Thought it was the Dyna 2000, but with the CR31's on, everything works perfectly.

I'll have some time to try debugging it over the holidays. The obvious place to look is on the fuel pressure side, though all the float bowls appear to be getting fuel. Frustrating, but not insurmountable.

Doctor_D · « **Reply #319 on:** December 08, 2011, 01:08:54 PM »

Well, I think i came up with a solution to accomodate my oil lines. Hopefully I'm on the right track, because I had to make some fairly significant mods to the engine and oil tank. Pictures forthcoming.

I'll start with the parts list:

Russell 610100    Hose End -8AN 45 Deg x 2
Russell 612100   Hose End 3/8" NPT 90 Deg Swivel x2
Russell 660483 -8 AN to 3/8" NPT Adapter x2
Russell 632103    Pro Classic Hose -8AN 3 ft
3/8" NPT tap drill
19/32" drill bit

I'll leave it up to your imagination at this point.

We got it down to 420 lbs wet.

Looks good I think the anodized ends on the oil lines look great. I spy a Fan-KEWLED ducati behind it looks lika a cadet model.. neat.

420 lbs sounds pretty good.
