just to get this straight.. when setting oil pump stroke, more stroke means more oil?? factory specs are .0080-.01" i beleive. ive seen a rebuild spec card from ed toomey showing a rd400 pump set to .012" is that what i should set mine to?? im fine with a bit more oil

How much longer were the DG swingarms over stock? +1" on the rd350 and also +1 on the rd400? And how long is a stock rd400 swingarm from center of pivot bolt to center of adjuster? Im in the process of getting a replica DG arm made up and it appears that a previous owner had mounted the stock 350 swingarm on my 400. trying to confirm this.

I'm looking at buying some rd400 cylinders here in Canada. The guy selling doesn't know what he is looking at. He has a few daytona parts in his collection. How do I tell what year the cylinders are from?  Also I know the euro 2r9 cylinders are sought after. Are the Canadian 3j7 cylinders simular? Can I run them on my 77?

Grew a pair and removed the goodridge banjo pressure switch. Yup was the wrong pitch. Great. Rear shock nut threads on fine. Found an email from nick and he gave me the wrong part number for the switch. Pbl992-32ch. Oh well it doesn't leak so I will keep it like this until it does. Just for future reference these brembo masters take m10x1.0 thread pitch

Shopping around at economy cycle and noticed they list a throttle grip washer. Mine was missing so I will try one of those and new repro throttle cable this spring and see how that feels

Here's the damper. It's steel and it's 17mm around the tube. Reason I ask is because previous owner bought the bike crashed. He replaced the forks so I just want to confirm what year they are from.

I read an old article on rd suspension recently that stated the early 76 rd400 came with a 13mm damper rod and the later ones had the improved 17mm ones. Is this accurate? Where am I measuring mine to find out what I have? The center shank I assume. Thanks

I have the vintage smoke rear sets for the rd400 c/d/e models. I remember a couple years ago when I installed them having the banjo bolt thread in with difficulty. I used the supplied banjo/ brake light switch from VS. Did I get the wrong pitch one, and can anybody confirm what brembo master is used for this? Google images show it looks similar to a 2007-2008 yamaha r1 rear master. Intimidated to take the bolt out without having the correct parts on hand. Haven't been able to get a reply from Nick at VS for a couple years

I'm planning on cleaning up my dash on my rd400 and would like to relocate an ignition switch. I've seen it done in the frame gusset by the horn or in the headlight. I'd like to use a yamaha switch but I've come across a Honda cb750 switch that looks like it would mount easier into a hole. What switches have you guys used in the past for this type of thing. I've noticed varying numbers of wires out the back on diffrent ones

I've got a daytona head I would like to get cut in half at a local machine shop. The plan is to send it to John ritter to get turned on his lathe but he can't cut it in house. I've seen them cut 2 ways. Offset on the middle fin with a hole drilled in the center and chucks way which is dead straight down the center splitting the middle fin. Does anyone know which way is better? I like the offset way better but chuck must do his centered for a good reason. Any input?

Was browsing the web and came across this xs650 speedo eliminator. I know there's lots of similarities in these front wheels with the rd350's and rd400's. I emailed the owner of HHB and he stated he believes they will fit on the rd's aswell. Anyone here know forsure?

Not mine. They were exactly as shown in the second picture

Did some more digging with your guys help and stumbled across these. They look correct.

The parts counter guy pulled out HD handle bar bushings and they were not close to the same size.

I've had my vintage smoke rear sets for my rd400 for a couple seasons now and really like them. The only issue I have with them is the exhaust hanger bushings. They wear out super quick if you take the pipes off a couple times. What are you guys doing as a replacement for these. I've tried countless times to reach out to nick at vintage smoke with no reply. Someone on here mentioned it was possibly a Harley Davidson part. Went to the HD parts counter today and nobody there recognized them let alone seen clear parts on a Harley. I know I'm not the only one with this issue. How do I replace these bushings!
