felix168, where in CA are you?

I'm considering replacing shocks on my 500 so it's a smoother ride going over bumps and pot holes here in LA. Just don't know where to start...
Up north, between Sacramento and San Francisco.

Based on what CubsKing99 is saying about these 14.5" - 16" shocks being oversprung, they're not going to give you much of a smooth ride. However, you can try these:

http://www.ebay.com/itm/14-Shocks-Absorbers-Eye-to-Eye-Mount-One-PAIR-Expedited-Shipping-/291031610157?pt=Motorcycles_Parts_Accessories&hash=item43c2d5f32d&vxp=mtr

By the way, the seller is down in LA and has a shop down there, so you can get some advise from him as well.

Let me know what else I can help you with.

I actually ordered a set of those last night. Whenever they get here, we'll see if they're better...

Just curious, even though the ones that you have on were over sprung, were they giving you such an over firm ride that you decided to go with the softer springs? I thought you said you didn't notice any difference in ride from your original ones.

Thanks.

No, I said I wasn't sure if they were better. After a couple thousand miles, I do think they were better than stock. But I think these other ones are closer to ideal, so we'll give them a go and see.

Oh I see. Well, if you think they're better than stock, I would sweat about the ones that I have for now. I probably will install them on the 4th when I have more time to mess with it.

I did get a set of 14" shocks. They're acting exactly the same.

LM15 is supposed to be visiting a performance shock place near his house to find out if there's a way to swap springs or otherwise adjust these shocks to perform better, but I haven't heard any progress reports from him.

Unfortunately, I don't know of any shops in my area that could do the same. I've got a co-worker who could get me a good discount on parts out of the Parts Unlimited catalog, but I don't even know where to begin without some expert guidance

Thanks - I got the 14.5" and they too seem oversprung but livable. Just wondering if the smaller ones were any better.

After a few highway rides the shocks seem pretty decent. At slower speeds you do feel the bumps a tad more, but well worth it being able to flat foot it

With all the talk on shocks I'm wondering how you know if it has to be changed. I have around 30,000km on the scoot and never thought of changing.
Also am I the only one who has never changed the adjustment from the day I bought my 250. It's on the original factory setting.

RFY Shocks
I recently got a pair of the 14" RFY gold colored shocks. After attaching them to the scoot I noticed that the one on the right side appears to be higher than the left side. Shouldn't the attachment points be level & symmetrical from side to side? I added the blue lines to show how off the two sides are.

Anyone know the reason for this asymmetrical setup and if the shocks need to be adjusted differently from each other?

OAD is right . Cannot tell from that shot but it looks like you need a new rear tire!

Those look like LED turn signals. Do they have inline resistors, do they hyper-blink, or did you find a way to replace the flasher relay?

As for the shocks being uneven, I've never noticed that. I'll take a look at mine later and see if mine is similar...

after you guys put the scoots on the center stands measure the distance from the floor to the top shock mount bolt on each side.

what you will find is the right one is a bit higher than the left, thus the offset on the lower mount.

Was hoping for you guys to figure this out before I said anything.

You can tell this by the pic that cubs is referring to on the turn signals discovery. look closely.

1. Putting the scoot on the center stand doesn't change anything.
As you can tell in the photo the lower attachment points aren't even in line with one another and if you feel up under your tail you'll discover the upper right attachment point is higher than the left.

2. I dont need a new tire, the white gravel dust may make it look like it has a flat ridge but the tread is still deep in the center of the tire.

3. Yes the blinkers blink a little faster and I think it draws more attention to the blinker which is what I want.

But back to the topic of the shocks.... Why are they asymmetrical?

noting wrong with having 1 shock mount a bit higher than the other.
make sure you adjust the shocks the same amount of turns on each.
They work in unison

I guess that explains why I have so much more trouble getting the ratchet on the right side upper shock mount...

So, I finally succeeded in finding a place around here that can do shock work. I took my bike in today to have them look at it. After a quick look, the expert thinks the springs actually don't look too strong. He thinks it might be more a problem with the oil/bladder/valving on the shocks. But even if it is the springs that are the problem, he can get replacements for me, but they'd be somewhere in the $100 to $150 range per spring. I'll need to take the shocks off the bike and bring them down to their shock shop so they can work with them sometime next week.

Oh, and for future reference, I believe these are a knock-off of the Íhlins Type 36PL...

So is a Peugeot Metropolis a knock-off of the Piaggio MP3?

I don't know. How much of the design did they lift (legally or illegally) from Piaggio? The RFY shocks are nearly exact copies of Ohlins shocks, coming from a country that shows very little respect from Intellectual Property laws...

With the day off for Labor Day yesterday, I was able to do some work on the shocks. I tried one of the things the shock expert I talked to on Saturday suggested. When I mentioned that it seemed like the spring was about twice as stiff as I thought it needed to be and that I'd thought about running it as a mono shock instead of dual, he said that it might be worth leaving both shocks on but removing the spring from one side.

With some help from my dad, I was able to get the spring compressed and unscrew the bottom on one side so I could take it off. I took it for a short spin last night and found it'd gone just a bit too far in the other direction. It was too soft. I think the sag was between 35-40mm.

As I thought about it today, I realized the preload was adjusted all the way out on the remaining spring. I could increase the spring rate by just cranking the adjustment down a bit.

After work, I worked on it some more and got it pretty well dialed in, as far as I can tell. It might still be a little too much sag, but when I went for a ride that had bottomed out the bump stop yesterday, it didn't tonight.

Since I had the spring off and easily accessible, I took some measurements with my digital caliper. Here's the vital stats:

* 8.25mm coil thickness (wire diameter)

* 45.30mm inside diameter of the spring

* 11 active coils

* 220mm tall uncompressed

* 200mm tall when mounted, from retaining ring to retaining ring (meaning it's already compressed 20mm when assembled)

* When I stopped adjusting, the spring measured at 190mm.

I'm not sure if that anybody else will care, but there's the stats. Now, with the measurements, I believe there are equations that can give the spring rate as well as determine what would need to be changed to tune the suspension.

Hope it will all work out to your liking. However, I supposed the springs are there for a reason.

That was on the 16" shocks. I hadn't done anything on the 14" ones. I did add pressure after I set the height last night, and it seems to have helped.

Sounds like it probably would. It doesn't have any load ratings listed for the springs, though. And that's assuming 335 - 380 is an adjustment range and not a measure that says 335 eye-to-eye and 380 end to end. It sure sounds like it'd be worth contacting them.

Dunno. I believe it's an M8 bolt, but I don't remember for sure. I know it has a 13mm head and a 17mm nut, and I think I replaced one with a 3/8" bolt on mine when I misplaced the proper bolt, but I don't know if that helps...
