You covered it well. I could have done with this vid a bout 4 years ago when I first started pulling racing SV forks apart.

k-tech linear springs from the UK are made to match the original springs in length but in various spring rates so if you don't fit emulators you don't need to cut the spacers down.

Great video, however, the rebound damping is not influenced by the emulator so you should not weld up your rebound orifice. When you purchase valve emulators as part of a kit the usually supply the correct weight of damping oil to make the rebound damping appropriate for the supplied spring rate and preload spacer which is likely to be shorter by the depth of the emulator, mut also influenced by the length of the new spring and the preload required on it. The emulators only influence compression damping, so your rebound orifice remains vital.

im not sure that's accurate. primarily because the traxxion rods (drop in replacement) did not have the hole. also, the community has pretty much been filling those holes forever with good results. the emulator absolutely DOES have a rebound hole in it (otherwise none of this would work at all since it sits above the damper rod).

Mind me asking if the procedure is same for gen 3? Plugging up that rebound that little hole? I've got some emulators installed 15W oil 95mm oil level but no modifications to the damper rod yet.

@coastriderscc3939 4 ай бұрын

With the addition of the emulator and drilling out and plugging of the breather hole, what volume and weight of fork oil is recommended? 20w?

@mikehunt3987 Күн бұрын

You set the air gap to stock spec, but you measure it with the emulators installed, but no springs/spacers and fork fully compressed.

I have to rebuild the Showa forks on my '89 Honda that has damping rod forks. If I'm going to do that, I thought I, may as well upgrade them with progressive springs and emulators while they're apart. The thing is, while looking for parts, I found a brand new pair of Showa forks for an '04 Hornet CB600F. These are exactly the same dimensions as mine, and even use the same brake calipers, only the mudguard mounts are different.... externally. Internally they're much more modern, adjustable cartridge forks. My long-winded question is: Will the cartridge forks be much better performing than the rebuilt originals? Oddly, as they're not coming from Honda, the price for the new pair is only less than $100 more than the cost of parts to do the rebuild myself. All I'd have to do with the new ones is fit them, and get a Hornet mudguard. In light of that, I know it makes more sense to get the new pair, but I'm really curious if there would be a noticeable difference while riding?

"progressive springs": ewwww just get straight rate springs that are correct for your weight 89 honda.... hawk gt? I dont think the 599's forks are much better (still squishy and still need to be rebuilt/resprung). but then you can run the dual rotor wheel from the hornet so there's that... f3 forks might also be an option

@billjackson3642 3 жыл бұрын

if the seals are in a decent condition (not cracked etc) then you could try a seal mate (or you can make your own one out of a smooth plastic like a drink bottle and sand the edges smooth with ultra fine sandpaper) I have used these successfully in the past. but if you have heard of seal savers/shock socks they are neoprene covers that protect the seal area I now fit them to my bicycles and my SV and ever since I have had no problems with leaking forks since because no dirt can ever get in I had to open one for the annual inspection i popped the dust cap up and it was immaculate in there not a spec of dirt in just under 2 years of all weather riding.

@Mad8vCycles 3 жыл бұрын

Sitting does more damage to seals from what ive found. When they're not worked they dry out and leak

Why are my springs so much longer? My preload spacers are only about 2 inches long (2nd gen naked, stock)

@Mad8vCycles 2 ай бұрын

probably cause these are 1g?

@Mad8vCycles 2 ай бұрын

err actually, these are highter spring rate (.90) so they're different

Thanks. I thought the fork lower in the background looked like a 2nd gen. I replaced my stock springs for 9.5 and they’re also long

So is it better to get imulaters or swap with a GSXR front?

@Mad8vCycles Жыл бұрын

It's significantly cheaper and easier to do springs and emulators. Gsxr front would still need to be sprung to your weight and comes with a few annoying tradeoffs

@julieoliver8170 Жыл бұрын

That what I want to know.

@Mad8vCycles Жыл бұрын

Annoying things to deal with for gsxr: Depending on year/model you might end up with legs a bit too short, or with losing steering lock. And you will have to deal with setting up a speed sensor. And have to get a weird risered clipon of some kind (or the clipons will rub the fairing)
