    Speed Wobble!

    Guys, I finally figured out what was going on with my static sag. I had been measuring it while the bike was on it's kick stand. I tried measuring with the bike upright and I'm at 39mm static sag, on the stiffer end of the scale but still no need to change springs.

    **Update: I just checked rider sag and static sag and I'm at 102mm and only 2mm static sag! Last time I checked rider sag was after my first ride a month and a half ago. The weird part is that I checked the static sag just yesterday and it was at 11mm. I haven't touched the spring or ridden the bike in between now and yesterday either. And I am bumping the shock before checking so that's not the problem. The process I am using to check is exactly the same as before. At this point idk what the heck is going on lol

    When I set my rider sag I was sitting directly over the pegs with my feet barely touching the ground in front of the pegs. I had all my gear on including my hydration backpack (~170lb total). Shouldn't I be fully geared up when I set the sag? I followed all the directions online. I can try checking it again I guess.

    Thanks for explaining. That makes sense! I should mention that the spring lock-nut is right were the middle of the threading is. Wouldn't it be closer to the top or bottom if I needed a different spring?

    From what I've read on static sag set up, it's apparently the other way around. And according to those sites my spring is too soft (11mm static sag after setting rider sag at 103mm). Which doesn't make sense to me either because the bike's suspension feels a bit stiff for my preference (my IT200 had wayyyy too soft suspension so that's probably why). There is no way I'm getting a stiffer spring lol. The stock spring is supposed to support ~160-180 lb. riders, and I weigh about 170 fully loaded with gear.

    Oh hey Jason! haha yeah the speed wobble usually happens not far from Becker Lake. Are you sure 10psi isn't too low? What psi do you run in the front? The singletrack at Noble has a lot of roots and sharp rocks so I am hesitant. I have got pinched tubes at 10psi before on less rugged terrain.

    To answer your questions: -The steering bearings are just perfect, not loose enough to flop side to side on a stand, but still smoothly moves on its own if you flick the bars gently. -My rider sag for the rear shock is ~103mm. -My YZ250X reaches 144km/h quite fast (I rarely use 5th gear), were as the IT200 hit 135km/h but had slow acceleration in 5th and 6th. With the YZ the engine still has plenty of pop left in 5th gear, so possibly the sharper variations in power could also be factoring into the head shake? -My tire pressure is always around 12-13 front, and 14 rear. I risk pinching a tube if I go lower. -Rims, Tires, and forks are all aligned. ***I was riding with some buddies today at the same place and we were ripping along the dirt road on our way back, I was following a WR250 2-Stroke and suddenly he got violent head shake and careened off a 10 ft drop into a ditch on the side of the road. Somehow he landed it and had enough room to recover. I thought he would go down HARD. He was practically in shock and said that was the first time he had ever got head shake. We went over what happened and he had gone over some shallow small pot holes and the front end started skipping side to side. There was like 10ft. between each tire track!! Too bad I had the GoPro off. I didn't get head shake at all today, I think it's because I know what to avoid doing for high speed. I keep my weight at the back, elbows out, smooth on the throttle, and be careful going over potholes.

    My forks in the triple clamps look just like the ones in the picture.

    Yeah I'm talkin' head shake. idk if tightening the steering bearings is a good idea because I've read that if they're too tight that will also cause head shake.

    Thank you all for the input! I have checked it all over, and I already had set the rider sag for my weight (155lbs). I also had softened the forks 3 clicks because the stock setting was too stiff for me. I do a wide variety of riding with the bike from tight singletrack to gravel pits to high-speed, so I need to keep a bit of a balance in performance. If I keep my weight towards the back hopefully it won't get speed wobble.

    That is how the bike was brand new.

    Speed Wobble!

    Hey all! I recently bought a brand new Yamaha YZ250X. Sometimes when I'm in 4rth or 5th gear I get speed wobble (on dirt roads). Last time I went riding I got really bad speed wobble but managed to straighten her out. I don't want that to happen again! I have done some research but everything checks out ok on the bike. I have had several bikes, but speed wobble has never come into play before. The front end on this bike doesn't feel as stable as my previous IT200 and KDX200 (but then again, newer bikes feel totally different). My forks are already dropped all the way in the triple clamps, the front tire is aligned perfectly, the bearings are all good, and I have adjusted the suspension. I think it may just be my riding position is sometimes allowing speed wobble to happen, as it doesn't happen all the time. Can someone please give me a good description of what riding position is best for high-speed?

    bushing Gio X31 250cc Linkage Bushings

    Hey ya'll! I've been riding my Gio X31 250cc really hard lately and one of the rear linkage bushings went. Now it makes a horrible squeaking noise lol. Does anyone know were I can get replacement bushings or if there are any compatible bushings from name-brand bikes? Thanks, Jordan
  14. Hey all! I have a 2011 Gio X31 250cc that is losing compression gradually. It had amazing compression when it was new...but now it's becoming a tiresome task to kick-start when my electric start is down. It's burning a small amount of oil, but I don't even have to top it up between oil changes (~10 hrs. per change). I'm thinking it just needs a valve adjustment to bring the compression back up. I'm surprised how good this engine has been. I ride it hard and it keeps up with bikes 2-3x the hp and refuses to die! I don't know how to adjust the valves on a 4-stroke, let alone a Chinese one. If any of you know how to adjust the valves on a Gio X31 250cc I would appreciate the help! Do I need to pull the engine for this? Thanks

    Suspension Too Soft!

    It is a YZ250 shock but very similar and about 1/2 inch longer travel. The guy who restored it is an expert with YZ's and IT's and other bikes so I trust that he knew what he was doing. It does seem to feel very similar to the forks, but the rebound on that rear shock is dangerous.
