Might not suit you since I'm guessing you're in UK but... Stadium Suspensions in Quebec, Canada do rebuild the Oll

How dead it is ? If a seal blew up, it might be possible to have it rebuilt. I had one leaking and had it rebuilt in a suspension shop. As for a choice of replacement, depending on what year model you have, you could buy another Oll

Some photos are popping out right now on some french websites. At the first look, the frame seem unchanged but it is said the geometry has changed (some mention about a rake angle change, nothing clear of the other changes?) A new frame is said to be due but only for the 2010 model. More official details from the factory should soon follow...

I will be there this year and have to decide what difficulty level I'll ride. Can anyone that went there previously describe the typical S2 vs S3 lines ? Is S3 only turns, no steps, no "hopping" at all ? And is S2 much more difficult than S3 ? I did watch a few videos to make up my mind but sometimes videos don't give you the right idea... also 1 section might look easy but then 4 days of it is a probably a different story.. Anyone going this year ? Thanks. Hugo

Check on the ATAQ photo museum page, there is a Honda section and a few of them are posted there. (on page 3) http://www.ataq.qc.ca/galerie/index.php?fo.../Mus%E9e/Honda/

Hi copemech, I think you're right, can't be simpler than that.For those who want to picture it, see fig. 14 of this diagram: http://www.dellorto.co.uk/editor/uploads/i.../floatlevel.pdf "hold the carburettor upside down and check that the float is parallel to the carburettor surface" According to this document however the technique described would give a 24mm float height. Now why Sherco mentions 18.5mm ? I guess it's time to take the carb off and figure it out / validate all this. Hugo

Here's the link to RYP regarding the 2006 forks information: http://www.shercousa.com/pdfs/2006fork.pdf (The document was posted for the 2006 models at the time but I believe the same would be applicable to 2007 as well.) Now for the oil weight, the document specifies "OJ RACING TYPE 01" - If you're interested in comparing this "OJ racing oil" with other brands, the folllowing chart gets useful: http://www.gasgasrider.org/html/susp-oil.htm Interesting to see that differents oils marketed under the same "weight number" don't actually have the same viscosity at all.

If you read the posts in this thread, you'll see people use various mixing ratios, ranging from 50:1 to 100:1 Sherco recommends 50:1 (2%), this is a "safe" number. I think the majority of users go with a little less oil, resulting in less build up in the exhaust system and no plug fouling. It depends on the use you are doing with your machine. If you do 100% trial with spending most of the time at idle speed, you could use a ratio of 100:1. If on the opposite, if you do more trail riding, then 50:1 would be more suitable. I personnally mix at 90:1 Now, since you seem to be looking for exact quantities. 50:1 means 50 parts of fuel for 1 part of oil, so 20ml of oil for 1 litre of fuel. 75:1 = 13.3 ml oil / 1 litre fuel 90:1 = 11.1 ml oil / 1 litre fuel 100:1 = 10 ml oil / 1 litre fuel etc. Hugo

For sure the oil qty for a 250 vs a 290 is the same. For this specific year (2000), I have never seen any documentation but since all other years are 450ml and that the base of the 2000 looks very similar, I doubt the required qty would be anything different.

As dibdab mentionned, 450ml is the correct quantity. The oil you were using in your GG transmission should work fine. Both GG and Sherco recommend SAE 10w40 oil but many riders run thinner oil such as 5w30 or even ATF transmission oil. Take note that all the basic maintenance info can be found on the one-page manual for you bike.

Hi Neo, If you want to swap the spring, think of removing it from the top instead of the bottom. No need to unscrew the bottom end at all. If I remember well : Once you loosen the allen of the spring compression ring, unscrew that compression ring completely so it falls on the bottom end. Your spring will then be loose so you can access the top of the unit, where is a kind of circlip holding the top ring. Once you undo the circlip, the top ring will be removable and then you can pull out the spring this way. Hugo

They're rebuildable if the suspension shop you deal with is willing to spend some time on it... In it's stock form, there is no valve to re-pressurize it, making people say "it's not rebuildable" but there is room to install a valve. That's what Stadium suspensions did on mine. Since you're in Maine, not to far from Quebec, you might consider sending it to them. (www.stadiumsuspension.com Phone : 450.464.4730 talk to Thierry.)

Not that I want to push the thread off-topic but regarding that little sticker asking you to fill the bike with “98” fuel… It’s good to know that Europe uses RON (Research Octane Number), while USA & Canada, for example, use an average of the RON and MON (Motor Octane Number). So for the same fuel, the numbers appearing on the pump at the gas station will differ depending on where in the world you are… Example: Regular fuel rated 87 in the USA would be the same as the 91-92 in Europe. Premium 93 in US would be similar to the 98 in Europe. Hugo

The screws on the top of your 2003 forks are intended to release the air from them. As the manual says: "The exclusive Paioli front fork includes an air exhaust valve located on the blue plastic cap on top of the fork leg. We strongly recommend to remove all the extra air inside the front fork to have the best performances and smoothness every 5 hours of function." If you don't have that manual, I suggest you download it. Here's the link from Sherco: http://www.sherco-moto.com/downloads/service/03_manual.pdf Hugo

No, the one straight from the GG won't fit the Sherco. (Maybe you can have it modified. Not sure of what would be involved exactly...) By the way I finally had mine (my Oll

Hi Teamsteevo, Since the time you've posted this, have you seen any other cases of Shercos equipped with a Montesa wheel ? Can you give us an update as for fitting the 4RT wheel on it ? I would be interested in getting a 4RT wheel (32 spokes) as opposed to the older Montesa wheel (36 spokes) and would like to confirm if the spacer-swap trick as you described here works well with that wheel (Sherco spacer on the disc side, Monty spacer on the sprocket side) - Anybody tried it ? I want to have a 2nd wheel, would keep the current wheel as a spare/practice wheel with a not-so-new tire and use the Monty wheel for events (and gain confidence against spoke/rimband leaks) Thanks. Hugo Sherco 2.9 2006

Thanks for the hints… Maybe I was too quick to call it a leaking shock… As per motofire’s comment about the breather hose, I decided to check for any outside source of fluid… After removing the shock unit from the bike and even removing the spring, I noticed that some fluid was actually retained in the center of the bumper/cushion (that yellow mushy pad fitted on top of the shock’s shaft), so the actual fluid I was referring to was maybe not coming from the seal/shock itself (?) Not sure yet how fluid could be spilled over in that area (the breather hose is not in the way). Anyway, I’ve cleaned everything, bounced the bike a few times and it stays clean so far. Will give the bike a real ride soon and check again.

Hello Sherco riders, The rear shock started to leak on my 2006 Sherco 2.9. In owning 3 other trial bikes previously, (and some of them much older than this one), I never faced this problem. The shaft has no dent or mark whatsoever. It gets wet from oil just by hopping the bike. I clean it, hop on the bike and you see it gets messy again. Not a major leak, but there should be none at all. I guess it’s a matter of replacing a defective seal, but I know it’s not something you can do without the proper tools and expertise… - Do you think any suspension shop would be able to work on it or I need to find someone that works specifically on that brand (Olle), in which case it might be difficult to find one locally. - If the price is OK, upgrading for the 07 (adjustable shock) would be another option… would someone happen to know if the 07 shock will fit the 06 frame ? I know they changed the swingarm in 07 so I’m not sure of the compatibility. Thanks. Hugo

common plug gapping for trials application is 0.5-0.6 mm (around 0.020 inches)

I was looking for the same information and I see that your post stayed without any replies for a few months... Well, here's what I found on the sherco USA website, concerning all full size 06 models, not just the 125. Oil types and levels for the 2006 trials models Paioli front forks Oil level on right leg: 60mm With forks at bottom Quantity: 370 +/- 4 ml Oil level on left leg: 110mm With forks at bottom and without spring Quantity: 385+/- 4 ml It's a bit more oil than in the previous Shercos (my 2004 required 330ml if I remember correctly). In case you want to download the pdf, here's the link: http://www.shercousa.com/pdfs/2006fork.pdf Hugo

Two of the numerous posts on the topic can be found here: http://www.trialscentral.com/forums/index.php?showtopic=9171 http://www.trialscentral.com/forums/index.php?showtopic=9049 (mainly at the end of the thread) I had this issue, tried different stuff. I think the main point causing this problem is the rim tape not sealing well near the valve. If your rim tape does not fit well tight around the valve, the air finds its way there and then goes out trough each spoke. So if the rim tape fits loosely around the valve, try to seal it (many suggestions from grease to "silicon grease" to straight silicon, etc.). Also make sure the hole for the valve on the rim tape is not being pulled on one side or another, make sure it's perfectly in the center over the valve. I don't think trying to seal each spoke is a good solution, if the air reaches that point, then the rim tape is not doing its job in the first place. A new rim tape fitted on a clean rim without any chemical product at all might in fact be the solution

Topfun (Spain) also offers a spring for heavier riders, it is a Oll

I am also looking into doing this modification. About getting the 07 parts, I am concerned by the fact that the steering shaft is now a separate part (is it the same diameter as on the 06?) and that the ring nut (just under the upper tripple clamp) has a new part #. (not to mention the frame also changed, not sure if the steering tube ara is affected?). My point is, having not seen an 07 close enough, I'm not sure one can order only an upper triple clamp of the 07 to fit a "fat bar": there might be more parts involved. So if anyone makes the conversion using Sherco 07 parts it would be nice to hear some feedback. The V-Mar option for sure looks like easy, just swap the clamp and you're set. Same for the RYP, only it is more expensive. Thanks. Hugo
