  1. Today we’re going to be talking a little bit about automotive suspensions and how they work to smoothen the ride of your car. There are mainly three purposes of the automotive suspension system. First, they support the weight of the vehicle. Second, they maintain accurate tire contact with the ground. And third, they absorb any shock that you get through the road when you hit a bump. Most modern vehicles come with an independent front suspension. Which means if one wheel hits a bump it does not disturb the other wheel. Nowadays, people use Coil Spring to support the majority of weight in the car. As it has a really good characteristics for absorbing any bumps as you go up and down on the road. However Springs aren’t very good at dissipating that energy. In fact that’s why you have the shock absorber. Which is there to smoothen out the ride and make sure the tire maintains contact with the road. In modern passenger vehicles the two most popular suspensions are McPherson strut and double wishbone style of suspension. The main advantage of the McPherson strut suspension is that it’s really cheap and simple that’s why a lot of manufacturers are moving towards this design. The double wishbone design allows the wheel to stay perpendicular to the body as it navigates a corner or as it goes over a bump. And that maintains good tire contact patch no matter where the wheel is situated. Another advantage of this design is that it can be made adjustable where you can control the position of upper control arms ball Joints.

    PW80 replace/repair suspension

    Hi. I bought a Yamaha PW80 for my son (actually he bought it). It was relatively cheap and I thought everything on it is probably cheap to replace. Long before I expected it he is jumping it and the suspension is bottoming out. I was shocked when the bike shop told me it's high AU$300s for the rear suspension. There are aftermarket for AU$50 - AU$100 however I am very skeptical about the quality. Can anyone give me some advice please regarding a reliable aftermarket, whether there is a reconditioning kit, any other suggestions. I'm in Australia. Thanks Chris
  3. I'm in need of some suspension advice for my yz250f 2016. I have had it for about a season using stock springs and the settings on the clickers are stock (Forks: Rebound Dampaning 12 clicks out, Compression Dampaning 10 clicks out. Shock: Rebound Dampaning 13 clicks out, Fast Compression 1 1/4 turns out, Slow Compression 12 clicks out). I have changed them around and don't understand the concepts of what they do to much. So I put them back to stock because I have rode my bike like that the most. I Have done some research on clickers just can't figure it out. I have set my rider sag. But I feel like I could really benefit from from correct springs so I can feel clicker adjustments better. I have gone to race tech and trued there spring calculator but I don't know what they are asking when they ask for fork and shock lowered distance. But my weight will vary between 155-160 pounds. I ride lots of stuff like GNCC races, logging roads some hill climbs. I'm a shorter rider I think 5" 9' maybe less. I'm a pretty aggressive rider for only haveing a season under my belt I'm a B rider. If any other information is needed to help me I will give it. Thank you

    Second oil filter underneath shifter?

    Good day all, I am riding a new 2017 kx450f, the first four stroke i have ever owned. I am also new to actually setting up a bike for me (sag, clickers, air pressure in SFF Tac fork, etc.) I have been going through the owners manual, break in process, oil change vids on youtube etc. While on the genuine kawasaki parts site looking up part numbers, I noticed on the oil filter section that there is the regular oil filter on the right hand side of bike, and then another one on the left hand side under the shifter. The second one I have literally never changed, nor have i ever heard anyone ever mention it, or speak about changing it, and its part number is 49065A. http://www.genuinekawasakiparts.com/oemparts/a/kaw/57f5247e87a8660d6c7c9b66/oil-filter Are the engine oil, and tranny sump separated on this bike ie two different oils, one for engine, and one for tranny? Or is this just another filter entirely for the engine oil, and should it be changed frequently? Also, on the fork and shock clicker setting there is a sign that is similar to " S<--->H " for clicker adjustment. Can someone explain the basics of this? Compression=? Rebound=? Thanks!
  5. I'm a 61 yr. old woods rider with a 2003 YZ 300. Do no motocross, and little jumping because of my knees. The motor part of the bike is satisfactorily dialed.But the suspension is stone stock, and pretty brutal. I've decided to do the work myself because I,ve done bushings and seals before, and feel confident that I can do it. I have spent hours reading posts on this, but the sheer mass of it all has my head spinning. This would be easy, if I had money to throw at it. I have decided that buying One racetech kit for each end is acceptable, (Or some other viable alternative). I have read that the rebound in these forks is a major problem. Question: If I were to but one fork kit, which one would it be? What about the shock?Any input appreciated.

    Replacement options rear shock

    I've searched the forum for info on this, but can't find anything except for a shock in the TT shop. I'm in the process of rebuilding my 2005 SM, front to back. After running the engine into the ground, too little oil and stupidity, I have ordered a big bore kit. As I'm doing that, I want to get the suspension redone as well, but all the rebuilders over here refuse to service the OEM Showa rear shock, as it "will always be a poor quality shock". What are good replacement options? What is the OEM shock length eye-to-eye? Are there progressive springs for the forks? Thanks a lot!
  7. Hey guys, I've tried the big shops over the years and gotten mixed results. Now I'm thinking about trying one of the smaller guys to see if the personalized attention provides better bang for the buck. Heard great things about Cory at ProTune but can't reach him at the moment. Rode with a guy last weekend who recommended Mark at Moto-vations in Hickory, NC. I found a few good comments on-line, but hoping some of my fellow TT members can share first hand experience. Feel free to PM if you'd rather not share details for everybody to read! I have absolutely no complaints about the Xplore when I'm doing slow speed stuff or even doing high speed when it's only moderately rough. But it began to beat me up last weekend when I hit larger rocks and roots at closer to race pace.

    Stiction on WP Forks

    I would like to get my forks moving faster in order to respond to the smallbump-slowspeed chatter that bothers my ride. My valving is spot on (Race Tech Gold Valve), SKF seals are pretty fresh, and oil is at a good height. Ive come to the conclusion that im probably dealing with some stiction issues. Any tips on how to reduce this? Trying to find some low-budget solutions... (PLEASE dont suggest some kashima coating /ti-nitride fancy pantsy coating because im pennyless) Ive read some folks "polish" the inside of their fork tubes to reduce stiction. How do you polish these? Any special tools or technique?
  9. Looking for some info on suspension settings to use on my 2016 KX450 SFF Air Tac setup. I just started racing hare scrambles in Florida and its mainly sugar sand. The stock settings are way too stiff. Front tire just wants to wash out in turns so i know I have to lighten the psi a bit. Stock settings recommended are: 174 psi for INNER chamber. 14.5 psi for OUTER chamber and 203 psi for BALANCE chamber. I know thru many hours of riding I can dial it in myself but I figured there has to be someone on here who rides sand and has saved settings they use, Any help is appreciated!

    2016 Yz 250x

    First off I'm a mid pack b rider from Ohio that races hare scrambles, my weight is 170lbs. Problem I'm having on my Yz 250x is it is washing out in the mud, straight lines the front end is a sled, other wise feels great in dry conditions. Race sag at 108, was at 105,tried forks 5mm up in triple clamps, that helped alittle but then I felt like it was nose diving. So it's back flush now. Was running front compression at 10 and rebound 9. Shock 10c, 9r. I did take 20cc out of each fork leg so I can run the compression in more. I was out today and tested it multiple ways and the only way I got it to track descent in mud was forks at 7c 7r and shock 6c and 5r. That is way off from what manual states and if it's dry out those setting will fill like shit. Help please what is everyone else running there clickers at on the Yz 250x. Thanks
  11. Just got my first paycheck from my first formal job. So... if you had 800 bucks, what would you get for your 2015 KTM 300 XC-W? (I studied finance so dont tell me to save for my retirement or invest! that shit is #boring) Regards from Mexico!
  12. Hi Guys, I need to adjust (and probably do some maintenance) front and rear forks on my bike, so they can work better with my weight and height, as the previous owner was much taller than me. It is a 2015 KTM 250 XCW, and I am near Park Meadows Mall, so the closest to that area the better, but still more important to get a good, trusted mechanic, that someone has some experience with already. I thought about Fay Myers, as I assume they do that kind of work, but not sure how good they are. Any recommendations?
  13. Beta sent out an email bulletin today announcing Ohlins forks, shocks, and cartridges for all four and two stroke models (all means the XT too, I believe), excepting the 125 RR-S. RXF 48 Forks run about three grand with spring, TTX46 Flow shocks run about $1,100 bucks with spring, and TTX22 cartridge kit is about $1,300 with spring. Nothing on the web site yet. Fork manual here: http://files.constantcontact.com/546b6d10101/00096a0e-4397-4af1-8d9a-e3e9a1b84725.pdf Shock manual here: http://files.constantcontact.com/546b6d10101/51f54f39-9395-4992-881f-d357a31764b7.pdf Cartridge manual here: http://files.constantcontact.com/546b6d10101/c2f42b44-b205-4a8d-b0c7-483baee5fe04.pdf
  14. How much weight can be saved with a disc brake swap to an XT500 w drums? My front/rear weights are a staggering 138/198.
  15. I know there have been thousands of threads, etc talking about how to make the WP 4CS forks better. I have them on my 2016 KTM 350sxf and until fairly recently didn't really think they were that bad. I'm a 38yr old vet rider 165lbs...just started racing (yea I know, a little late), but have definitely put in a lot of seat time and am starting to understand the subtle nuances of the bike and the suspension. SO, naturally I looked for a way to make my forks work better. I live in San Diego, CA, so I have great access to Factory Connection, Race Tech, Pro Circuit, etc. WELL, for those of you that cannot seem to find the answer, I HAVE IT. I had a guy come recommended to me (Pete Russell) from someone at Pala...said he was hands down the best in the business. I took my forks to him and not only did he do an insane job revalving them, he had no problem walking me through every step as I watched him do it. His understanding of the inner workings was light years beyond my comprehension, and apparently superior to the big shops as well. Long story short, if you want your WP 4CS forks to be pure awesomeness, get your stuff done by Pete at NOST Suspension (www.nostsuspension.com). He has a 3-5 day turnaround time and charges waaayyy less than you'd pay for an A kit set up. EVERYTHING is custom machined parts that he developed and I could tell from the second my front tire hit the dirt that it was going to be a world of difference. I'm very very pleasantly surprised at how awesome my suspension is now...so time to start winning some races!!!!
  16. Hello, I'm looking for way to make a machine to vacuum/fill rear shock absorber. I checked, but i can not find a full topic with detailed project - making of... Does anyone have such an information, as I need to have the details and check if I'm able to make it?
  17. I have a 2014 Husaberg FE501 with 4CS suspension that was IMO mediocre compared to the open cartridge WP fork of the same generation. 1 week ago I purchased a 2018 300 XC-W and the initial feel was soft but not too shabby until I tried to dial some compression damping and NOTHING at all even at full +. I mentioned something to the dealer and they said "call KTM 1-951-600-8007" so I left a message and received a call back that went something like "Yeah they are sucky but thats the direction KTM went" and when I said I get the valving could be improved but the real issue is the adjusters should be on a keychain instead because they would do the same and be even more available to the customer, his response was "Sorry KTM hates its customers, CLICK". I had Kreft go through my 4CS and the results were stellar but this is an issue of KTM pawning off non-working garbage on its customers. Anyone else feel like the adjusters are just for show on the Xplor 48 fork and that the 4CS (as hard as this is to say) was better?
  18. Hi, I have a 2003 DRZ (actually a KLX400) and the head tube bearings are shot. I ordered a new set to install but I'm wondering if anyone has any recommendations on other parts I should replace while I have the front disassembled. I was thinking about new rubber fork protectors, but are there other things that wear out on the DRZ front ends that you can only get to when disassambled? I also broke off a replacement key that I got for the steering lock. I must have been made of cheap pot-metal. Should I just remove the whole lock mechanism? Any tips or tricks for getting the old bearings out and the new ones in would be welcome! Thanks!

    Front Fork Slack

    My question is in regards to my front forks for the second-hand bike I just purchased. I have been looking all over the internet for the last three days to find out a similar issue to mine, so I know where to start. When ever the bike is off the stand there is a excessive amount of slack in the front forks from the point where I pull the handlebars up to fully extend the forks to the point where the settled without out my weight on them. The issue is that there is virtually no tension in the process. The vertical free play/slack is far too much. Low oil, Shock springs worn, a need for spacers? I don't see any signs of leaking on the bushings. Compared to my other bike it is nowhere near the same. Im just wondering where to start and to look to help fix this because I can't find any troubleshooting that relates to this issue or has a term for this excessive vertical free play in the forks . The bike is a 2004 KX100. Any Info would be much appreciated. Thanks
  20. Hi my brother has a 2006 trx300ex and we were starting to go ride and about 3 minutes into our ride he stopped because he noticed the front right side of the quad sagging down and we looked at it and the Front right shock was snapped at the bottom where it connects to the A arm and oil was leaking out of it. Has anyone ever had this happen to them?

    Lowering a 2005 yz125

    I have 05yz125 and do mostly trail ride. I’m 5’8” and don’t ride often enough. I was considering lowering the stance of my bike to see if it make it easier to handle in tight trails. Any thought on linkage changes and how to adjust the front forks accordingly?

    2016 Kx450f

    I need help with my suspension set up, I just got a 2016 kx450f and the guy I got it from said he had it set up for him weighing 200lb. But me being only 140 its been killing me in the breaking bumps and just stiff as hell. I tried messing with everything. I went back to the stock setting for 155lb and it was still really hard. Any suggestion?
  23. I’m a DIY’fer all the way. But I’m wondering if I can change my Factory Connection springs (front: from .48 to .50, rear: from 6 to 6.7) on my 2012 YZ250 without changing other parts (other than obviously the seals for the forks) and if so what parts and where to buy them? There’s only a few parts available in the FC site that I could find. I already ordered my springs. What other type DIY service can be done? Any advice/guidance will be greatly appreciated! #yz250 #factoryconnection #doityourself #suspension #onabudget #frontforks #rearshock #spring #kyb
  24. Hey all, I have a model year 2000 drz400s that sits very low, the rear especially. It looks like all 2000s do from what google shows me. Why is this? I know so little has changed over the years and suspension is one of the things that actually has. Is the rear shock shorter? Linkage different? Anyone know?? I'd like to get the rear up to "modern" or "normal" height, the front I'm ditching for an SM front anyway. All searches I've done return only how to install lowering links to adjust height which obviously doesn't apply... Thanks!
