A friend bought a used KTM 400 with a Tubliss set up, front and rear. The problem with it, is that you have to air up every time you go riding. The 100 psi sealing ring leaks down after a day or so. Try finding a 100psi hose on an adventure camping ride. It's really for offroad competition IMO, to prevent tubes getting pinch flats in a race.

He took them off the bike in less than a month.

Thanks for the info on the Cogent vs PC shock. I'll go with Cogent. I'm going to send him my fork tubes too and have him do the work to them as well. Figure if the bike is gonna be down for a few weeks, might as well have both ends done.

Thumb Shocking!

All together took me about 2 hours to do including removing the shock from the bike. I still have to get it charged but will get that done tomorrow.

That is good news.
Interesting that PC doesn't list the new cushion rubber as part of the "solution".
You reused your seal head I am guessing.
I certainly like the price.

I am sure you will be glad you did.
I am always trying to save money but sometimes (too often) I end up paying twice.
Once for my cheap fix and then again for the correct fix.

Which reminds me, I am searching for a BSA B50 rear wheel if anyone has one....

We don't include it because not everyone will need one. If the shock is only a couple years old or less the bumper and seal head are probably perfectly fine. Riders with older shocks can add the seal head and bumper if they need them.

The photo above is the shaft assembly. You can see the rebound adjustment knob at the bottom. It does come with a new bumper.

That is very similar to a Cogent shock with all new parts, but YOU still get to do the rebuild.
So, looking at equals you see that a Cogent shock is less expensive, is ready to install, and is a completely new shock.
...
I thought the shaft shaft assy ($498) was complete and all that was needed was to add nitrogen, nothing to rebuild?

Ah, my mistake.
I make several each day...

I thought mrprez was saying that he had bought your $279 "Shock Solution Kit".

I wondered why the bottom of his shock looked different. Duh!

He got your "Shock Shaft Assembly" ($498) so it is very similar to a Cogent shock.

Thanks for clarifying that.

Direct from ProCycle, our favorite parts supplier:

Quote:
Shock Shaft Assembly with Rebound Adjustment

Replace the internal components in your shock with a completely updated design with adjustments for both compression and rebound damping.

The new shaft assembly has improved valving for both compressing and rebound, a thicker, stronger shaft, new seal head and bottoming bumper. Comes as a complete assembly ready to go into your shock body and includes your choice of rear spring (required). Other spring rates available by special order - call.
Unless I am wrong (again) you get all new INTERNALS but you have to take your shock apart and put it back together.

That is where mrprez helped out by saying it only took him 2 hours to do the job.

Now, back to juggling apples and oranges and bananas.

You're right.

I don't think you will regret having Rick do both ends. He did mine last year and I have been VERY satisfied with it. I could probably still see more improvement from a fork swap, but the resprung front forks with Racetech emulators are fine for me. The Cogent rebuild on the rear is outstanding.

Plus Rick and Joyce are great people!

I have the Cogent shock on my bike, and Intiminators up front. Very satisfied for my riding needs. Rick from Cogent also has a cartridge upgrade for the stock forks as another option.

Sorry my fault. I did get the entire shaft assembly not the solution kit. I used the solution kit on the front forks.

Starting problems

So, I have an interesting issue that's been plaguing me since I bought the bike. I'm having a problem getting the bike to start. I'll push the starter button with the key in and on. The clutch is in, the bike is in neutral, etc, but nothing happens. It doesn't even try to turn over. I'll press the button a few times, try turning the key on and off, and eventually, it'll start cranking and fire right up. I don't know if there's a short somewhere, but this seems fairly random. It doesn't seem to matter if the bike is really cold, been running for hours, or anything in between. It's a moderate inconvenience at this point, but if I stalled out in an intersection, it might be a bit more of an issue. Anyone else had this happen?
