All
I am starting a new project. A full restore of a 79 rd400f. I had bought one of these bikes new in 79, loved it. I found a basket case on ebay (5 baskets full). Its now in my garage and I am setting up the shop and researching the internet to get prepared for my first restore
 
Questions to all
Any advice on where to look for parts and info? I found HVC cycle, looked good. Also found a site with all the microfish(sp?);helpful. You get the idea... Any help or suggestions would be greatly appreciated.
Current focus areas:
1 Brake systems
2 Painting tank, fender, etc
3 Carbs (basically dont have any)
4 pipes: I like to get stock, but the old dg style is fine. Not into super loud anymore
5 Oil pump
 
I am not looking to get back to all original, just a good decent restore from the frame up
 
Thanks!

HVC is a good source.  I used SpecII for VM30 carbs, intake, chambers, and new brake lines.

I also have and like the Spec II "Classics" (2010 version).  I ran 1972 R5 carbs...HVC sells the cable to them.  But 30mm carbs are relatively cheap if you do your homework.

I wrote down some of what the top guys recommended for tuning a 30mm VM carb:

Supertune:  45 pilot, 210 main, 159-P2, 6DH3-2, 40:1 premix and slide cut to 2.7

Lyn G:  220 main, 45 pilot, 6F4-3 needle, 2.5 slide...assuming 159-P2 needle jet

MBSteve:  250 main, 6DH3-4, 159-P2, 2.0 turns airscrews, #30-35, 25:1 premix, slide cutaway 2.5~2.7 (he had a set of Gary Shumake/Spec II cut slides).

so this is a good selectin for a baseline.

on my R5 carbs:  1mm offset, oval / taper bored, 220 mains, 169-P2 needle jet, 5DP7-5, 55 pilots @ 1.5 turns airscrews, 2.0 slides (stock R5 slides), 1.7mm airjet, premix at 32:1, timing 1.75 mm BTDC, Spec II expansion chambers, Y-boot with tall uni filter, TDR "yellow" one piece reeds, RB Designs Dyna-S electronic ignition, 93? octane pump gas (non-ethanol when all possible).

Where are you located?  I know a fellow in Tennessee that paints bikes for a living.  Does a very nice job and vintage races a Yamaha DS 7.  His prices are reasonable and he knows all the original colors, markings, etc. 
 
I may have a set of Daytona carbs, I'll have a look.  I had a Daytona once and really liked it as a street bike.  I took the butterflys off the exhaust headers and the other emission nonsense and the bike ran quite well.  I think I put on a set of the regular 28mm Mikuni RD carbs, but that was a lot of years ago and I can't remember.  I'll look to see if I have the Daytona carbs and assess their condition.

I do have a pair of Daytona carbs.  They are complete, with the bracket that connect the pair, with the exception of the caps, springs, and slides.  I need to research the throttle cable/slide control device because as I recall, it is very different from the separate carbs and I don't know if I have those parts.  I almost certainly have every slide and jet needle that Mikuni put in the 28mm carbs so that wouldn't be a problem.  Let me know if you want me to look...

Do yourself a favor.  Buy the Zedder Yamaha part number  cross reference CD on EBay.  That online fiche is a good start but the Zedder x-ref allows you to find other bikes that share the parts, by P/N.  Thats especially important when you start getting away from the 278- or 360- type of pn's and you are looking at the 10 digit pn's. 

Also if you pick up a part you dont know what it is you can look it up by pn.  The fiche doesnt do that.

I aint Zedder, I just like his product:

Thanks to all. Great info. I am blown away by the collective knowledge!! Keep it coming; much appreciated!
 
Current thoughts: I will buy the spec 2 pipes and 30 VM carbs; seems like a good match (and proven). what should I expect to pay for the pipes, carbs, hardware, cables, etc.
 
Also the Zender database. cool stuff
 
Coincidentally I spoke to a friend this week who I had not seen in 20 plus years. We took a road trip in 79 to Nova Scocia on our RD's. Turns out that he does custom paint on bikes so I think I found my guy to paint the tanks. I now need to find the part number for the paint color, where to buy the paint (the white with the flakes in it), and a good place to buy the quality decals
 
Also, he knows where my old bike is that I bought new in 79!! (it's behind a shed, but left out in the weather)
 
Thanks!

here is a list of everyone on my favorits list for parts, most have already been mentioned
HVC cycle, i have ordered from them, and talked to them on the phone and email, they are very pleasant to deal with. economy cycle, reproduction decals, spec II, Flanders, Cedar Grove, Mikes XS, Parts N more, Motorcycle Superstore, Ebay, Dennis Kirk, Z1 enterprises, Speed and sport(i guess everyone says they suck, but i just use their website to look up part numbers, it works great)
also check out the forum's for sale and wanted posts, most of the people on here are hoarders of rd parts...LOL...they will give you a fair deal to help you out with a resto.

Awesome!
