Riding Boston, MA. again this year but not on the RD400.......got a Ural cT and the wife is the monkey! :P

So got a parts bike for $600........awesome deal, everything I'll need! ;D

Doing a new build, got the rest of my buddy's RD parts: 3 frames, 2 sets of wheels, an engine and a half LOL and lots more but no forks. This one is for vintage racing so don't really want to swap front end to XS or Daytona or the like but there isn't anything I can find out there at the...

Thanks to global warming/climate change myth the 70* February day we had made for a great first ride! Front suspension feels awesome, no abrupt top out now and a lot less vague than before.

Mine looks nothing like that! :o The changes I've made have made this fork so much better, looking forward to the first ride to really feel the difference.

Nope, 34mm! Got'm all back together this weekend. A few little custom tweaks and they feel great. Once the engine is back in I'll be able to set the the sag........the fact I'll be able to set sag is revolutionary, let alone getting rid of the hard top out completely!!!

Can't get pics for awhile.....on vacation now. Both damper rods look good. I'll post pics when back.

Nope you are right. Springs have too much pre load and too stiff for my weight and possibly oil weight was too light.

It's all apart right now, including the engine, which I just got the cylinders back from USA PowerSeal with two new Wiseco pistons. ;)

At 483mm the Progressive springs were 20mm above the top of the stanchions, there is no way the stock spacer could be used as it was difficult to even thread in the top caps without them. Forks must be stock length as you can see from the picture, they almost look a little too long. I'm hoping...

My limited and sketchy knowledge is that the spacer is removed when the progressive springs are used. I cut the springs down to 444mm and I got 20W oil.........just waiting on my order with the seals to put it all back together.

They seems to measure up correctly for a '76 to '78 RD400, no idea exactly what year they are from. My buddy bought lots of parts bikes back then. I got two extra frames, 2 oil tanks, 1 gas tank, 1 triple tree and boxes and boxes of carbs and parts of oil pumps and it goes on.

Thanks for your posts, they're are always insightful. :) They are 483mm and no fork spacer.........there is no way the fork spacer would fit. I'm going to cut these down about 20mm and up the oil weight. If that doesn't make it even a little better I'll try the emulators. I've seen a few...

Good info! Measured volume of oil was about 120mL per leg and whatever was left in it would have been correct, previous owner said 15W and what came out was red, almost like Rock Shox red rum! LOL I hear what you guys are saying, I was just seeing if anyone had ever tried to update/modify or...

Guys are kinda one dimensional!!?? Just cause they say it isn't available doesn't mean it can't be done. I'll check around at some machine shops.
