Does anyone know of a good place to send my old shock for a rebuild and revalving? I believe it's a SHOWA?? I found a new Penske shock for about $750 w/ compression dampening, but before dropping that kind of coin, thought I'd check with you guys. Also, anyone have experience with EMULATORS?

Hi bikingreenie,

DaveM and I have all new members read the stickies above and provide a intro for the other members. Thanks
As far as rebuilding the rear shock, DaveM is the one to answer that.

BG,

There are several threads on this forum about both shocks and forks. However, the 'Search' feature is a bit of a chore.

Short answer: The Showa shock is a base-model. You can pay roughly $400 to have someone like Traxxion in Atlanta or Race-Tech in CA rebuild it, but then you'd have a freshened base-model. It would have a spring better suited to your application, though.

Ohlins does not offer a shock for the ST/RS. They used to.

The forks are also softly sprung, and are also 'base-models'. You can try springs with a higher rate, or try to put in a bigger spacer to increase pre-load. Most have found that the front seems to like 15W oil, which is a bit thicker than the 8W factory fill.

Apparently, the emulators work very well, judging from posts from those who've installed them.

Remember that the front and the back of the bike will respond to tuning of the opposite end. So, if your shock is replaced with a silky smooth, properly rated and damped unit, the front will become glaringly insufficient. And, Vicki Verki.

FWIW, I went with 15W oil, a couple of PVC spacers and had a 1000lb/in spring put on the shock. I'm not sophisticated enough to need a better suspension, but my bike seems to ride great.

HTH!

2 things:

-The stocker is a step up from base-model, as it does at least have preload & rebound adjusters.

-I was recently quoted $200 for rebuild + $100 for a spring by Traxxion. The spring is only necessary if your weight is significantly off from the (160 pound?) target weight of the stocker.

HTH!
It might not get any better for you- a lot of times "better" means "more adjustable" for forks & shocks, but if you have the stockers properly adjusted all the extra clickers in the world won't necessarily make your ride any better.

Edit: Oh, as far as emulators go... I run Parallels on my Mac. It handles all my Windows needs quite well, including TuneBoy & TuneEdit.

Cheers,

Welcome to the forum bikingreenie:)

Short answer is yes and Kit is closest to the money.

I had my Showa rear monoshock unit rebuilt here in Brisbane by a local suspension specialist called RAD shockie repairs.

Kit is right it is not the base unit and Showa suspension is quality kit it just doesn't have full adjustment like a sports bike shock does.

Mine cost $172.00AUD without replacing the spring which would have been at least another $100AUD.
RAD did a full rebuild in that the shock was cut open re valved to suit my weight and riding style , re gassed and oiled etc and put back together with a 5mm spacer on the rear spring.

For minimum outlay the result is nothing short of fantastic.
I have a firm but very compliant rear unit that sticks to the road like glue on the bumpiest of roads.
I run 15wt oil in my front forks and have them flush with the triple clamp.

My '04 Sprint ST handles and tracks through corners like a Rhino on heat:D

Please check out the tyre porn in my album links below in my sig with particular attention to the front tyre photos to prove my point.

Yes you can spend big bucks on a new fancy smancy shocker if you want but IMHO it is not necessary to produce a fine handling bike for the road.

Bottom line;
If you have that much money well good for you but you don't need to send a lot of money to make a Sprint handle brilliantly.

Let us know how you get on.

cheers,
DaveM:cool:

Rebuild

Thanks Dave.
I called a local suspension guy and he asked me to send pics of the shock. I found one on Ebay and sent him the pics to save time.
My local dealer said "it can't be done!" ...well, well, well.

I called Traxxion and they said,"of course we can". $150 rebuild, $50 revalve, $100 respring, there's $400 plus shipping.

For another $400 I can have a fully adjustable Penske. Damnit, I need to find a Penske on Ebay for $250!

Does anyone know if any of the Jap Sportbikes will interchange? Just a thought...

You are welcome mate and good luck with the hunting.

I am not aware of any Jap shockers fitting, some have said the Daytona 955 shock fits but I wouldn't be too sure about that as for some reason I thought it was longer.

I own a big D '04 and an '04 Sprint the Daytona 955 shock has a large gas resevior you would have to mount somewhere if the shock is the same length.

The Daytona 955 '04 shares the same single sided swing arm as my '04 Sprint.

Might be worth further investigation.

Good luck and let us know what you do.

cheers,
DaveM

I still get $300 there, not $400.

I happen to know that the last Penske on eBay went for $367.62. :D

I'm an idiot! Got me on the math!
Anyone need a math tudor for your kids? ...well, you know who not to call...

One thing to bear in mind is the clearance under the fuel tank for any kind of gas reservoir. I have been poking around under my tank (stupid, stupid fuel sender wiring) and there is very little extra space for anything on the Sprint.

The rebuild on the shocker sounds like a pretty good option to me. I haven't done it yet but run 15W oil in the front and I'm pretty happy with the handling.

I went down that road too- looking for a shock rebuilder for the Showa-- best I could find was a good dirt bike builder in Co. Spgs, CO who I knew would do a good job, but by the time I priced it all out, I'd found a good deal at Lindemann who just happened to have a custom built Penske for the RS and let me have it at a very good price-- as I recall around $600 with the additional compression adjuster. That meant the Penske mounted right up with everything the correct length, matching eyelets, etc. If you want to take things incrementally, it's fine-- try getting the proper spring for your weight and riding style first, then see what needs to be done to the shock, if anything. The Penske also has ride height adjustment along with the preload adjuster, etc. and its pretty easy to set or reset all of it. I'm not doing any two-up so, it makes my task a little easier-- doubt I'll ever need to readjust my preload.

Also, keep in mind the many factors that can affect ride and handling, not the least of which is your tires, pressures, etc., etc. You might want to run thru several different brands of tire before deciding how to modify your suspension.

I went with 15ml weight oil in the front with 15ml extra and it is a bit too much. I am going to visit RAD shockies in the next few months when i can get motivated to respring my sprung, :) or is that resprung my spring? :confused:

What is involved in a shock rebuild, aside from a more appropriate spring? Or is a rebuild required to replace the spring? I'm somewhat clueless when it comes to this stuff.

I'm ~270lb, frequently with a 140lb passenger. The stock suspension is... inadequate. :eek:

*edit: I have a 2007, so maybe this isn't an appropriate thread for my question?

lctrc,

You need a spring with a much higher compression rate. You can have that done rather cheaply (maybe $150), but the 'proper' fix is described above.

bikingreenie,

the Daytona shock does NOT fit the Sprint. It might fit a Speed Triple, but it is about an inch and change too long on the Sprint.

I've never done a rear shock myself, but have had them done. The rebuild consists of a cleaning, new seals, new oil, and refill of high pressure nitrogen.
Over time seals wear out and the compression dampening and rebound dampening basically quit working, thus your rear shock turns into a pogo stick.

The spring is a different matter altogether. You need to have the correct spring for your weight in order for everything else to work properly.

Your bike(s) being as new as they are may still have well working shocks, with the exception of the springs. At 270 lbs. I would imagine you need a heavier than stock spring.

I had my DR650 rear shock completely rebuilt, revalved, and resprung by Cogent Dynamics. It's a completely different motorcycle! Much smoother and stable at speed on the rough stuff. I just wish he could work his magic on my Sprint shock, but he can't.

I called Traxxion the other day and they were very helpful with information and a recommendation for what I need. I would recommend that you call them, tell them what bike you have, how much you weigh, and what type of riding you do. They can then tell you what you need.

I've finally learned that suspension trumps horsepower.

Get your suspension right, and you'll be amazed.

Any one know the length of a Daytona shock and the length of a Sprint shock?

I'm actually interested in fitting one of these up if its possible.

Length? 13.5"! "That's what she said..."

Sprint is 13.5", but don't tell your girl!
Because I hear the Daytona is longer

According to Ohlins or-http://performanceshock.com/Ohlins_mc_RT.pdf


344mm (13.5) Sprint
387.5mm(15.2") +/-12mm (.5") Daytona so, maybe 14.5"

Again, like she said "that's a big difference"

Daytona shock

I have mentioned this just recently because someone else said they were having a Daytona 955 shock re built for their Sprint.

I suggested they check first.

I am quite sure the Daytona shock is longer than the Sprint's and also has a large reservoir which might be difficult to place somewhere on a Sprint.

lctrc 270lbs + pillion you definitely need a heavier spring the stock Spring is not heavy to start with.
