Your steering head bearings may be loose or need to be replaced. Fork damage would also cause this. You can download a general Honda service manual here
Chapter 18 shows how to service your forks & steering stem. Haynes & Clymer also made manuals for your motorcycle, either shows the procedure in detail.

Depending on what the problem is, this could lead to catastrophic failure of your steering at an unexpected moment. I urge you to fix it as soon as possible.

How to tell if neck bearing on suzuki gsxr 750 slingshot needs replacement and or adjustment


I would start at the top of the front assembly and work down.The easiest way to check for a loose or damaged head stock bearing is to put the bike up on the centre stand,have someone push down on the rear taking all weight off the front tire, and push the tire assembly in and out.There should be absolutely no play in the wheel assembly or headstock. The drop may have backed the head stock nut off just enough to loosen the assembly. I would also check to make sure there isn't a slight bend in the front rim.Check the brake caliper for clearance and don't rule out the tire it might have damage you can't see.You may have even bent the front axle slightly.This might explain why you only feel it slowing down or turning.Good luck

2009 FLSTC. slight vibration and wheel wobble.


Hi Anonymous, and the usual suspects are:
1. Improperly loaded motorcycle. Non standard equipment on the front end such asheavy radio receivers, extra lightning equipment or luggage tends to cause unstable handling.
2. Incorrect air suspension pressure.
3. Damaged tire(s) or improper front-rear tire combination
4. Irregular or peaked front tire tread wear.
5. Incorrect tire pressure.
6. Shock absorber not functioning normally.
7. Loose wheel axle nuts.
8. Excessive wheel hub bearing play.
9. Improper vehicle alignment.
10.Steering head bearings improperly adjusted.
11. Tire and wheel unbalanced.
12. Rims and tires out of round or eccentric with hub.
13. Rims and tires out-of-true sideways.
14. Shock absorber improperly adjusted.
15. Worn engine stabilizer links.
16. Damaged rear engine isolation mounts.
17. Swing arm pivot shaft nut improperly tightened or assembled.
Good luck and have nice day

I have a 2007 Suzuki Boulevard C90T. Maybe it's my imagination, but lately when I am riding, the bike seems to behave like I'm on grooved payment. It happens really fast, and stops as quick as it...


It could be road conditions, but check the condition of your tires for any damage or incorrect air pressure. Have you changed tire brands lately? Go over the front and rear suspension with wrenches to make sure nothing is coming loose. An improperly mounted tire on the wheel rim can cause strange things. Hope some of this helps!

Handling seems alittle loose


I wouldn't think one as new as yours would have swingarm problems. Have you checked your air shocks lately? The FLHTC has air assisted suspension on the front and rear as best as I can remember.

One other thing, I have heard people complain about Dunlop tires. They say that they don't like them because of that problem. I've never noticed a problem with Dunlops but I ride a Wide Glide. I have recently changed to Metzler 880's tires. They seem to handle well but the braking is not too good on them. The rear tire will lock up and never make a sound. You don't know it's locked until the bike tries to go sideways a bit. Not good.

Good Luck
Steve

Tire pressure in manual is 21psi, front and 22psi for rear. Do I need to increase this for on road riding? Pressure seems low for on road riding?


Here's my take on tire pressures and when they need adjusted, I wrote this a while back for someone with a Honda African Twin, so this should help:


Manufacturer's recommendation – Short distance city riding below 100kph. Light off-road use ie. Small rocks, gravel. If the weather/road conditions vary a lot.


30% above recommended pressure – High speed road use. Long distances in warm weather on good quality roads. Go 40% if the conditions are the same but the bike is fully loaded with carriers.


15% below recommended pressure – Short distance riding in cold winter temps. Short distance on wet roads. Off-road, average gravel/rocks and some wet mud.


40% below recommended – Slow off-road riding in very loose dirt, sand, with lots of rocks. Tires will heat up quickly if the pace is picked up which will loose grip and cause accelerated wear.


60% below recommended – Very slow, loose dirt, deep sand (dunes). If tires slip on the rims you need to increase pressure.


My mantra is all about keeping a close eye on tire pressures and adjusting them to suit the conditions rather than keeping strictly at the manufacturer's settings. Starting out my riding career on a BMX, tire pressures can be the difference from landing a perfect jump and falling on your face. Therefore, with a motor attached, it is even more important to get it right – personally I think the 'feel and grip' is more important than the pressure number – regardless if that causes tire wear.


Hope this helps and you vote for me :)

1988 R100 rs 60K the bike seems unsteady in corners and on the freeway I just bought it the bike also pulls to the rt I try and do most maintenece myself is this something I can do thanks mike


Check the following:
Steering head bearings for play and looseness Front and rear tire pressures Front and rear wheel bearings for wear Rear fork bearings Also check over tires for irregular wear patterns that might be contributing to the loose feeling.

Front end wobble


First thing to do is check front and rear tyre pressures. Next check for un-even wear of front tyre. Then check steering head bearings for correct tightness. Also check for bent front brake disks as one side bent can cause this. Check for worn wheel bearings also. Check engine mount rubbers as these can cause floating on bends if worn of loose. Basically check all chassis related items fully.

Replacement tires on a Beo 200


I am thinking about my bike. Regarding replacement tires my 08 beo 200 has 100/80 (front) and 120/80 (rear). It is still early on in the tire's life cycle (only have 1300 miles) on it. They are the stock Cheng Shin tires. Dont really have anything to compare them against and have ridden in mostly dry conditions and just yesterday during and after a light misting but have no complaints in performance at all. Just looking down the road for when I do have to to replace the tires. I was considering getting tires with a bit more contact patch possibly 110/70 (front) and 130/70 (rear). This would give me more width and with a lower profile would possibly put me at the same diameter as the 80's. The ride will probably be more firm though. I have played around with cars and tires in the past, but two wheel dynamics are different so I am looking for the groups advice or input on the matter,I have been considering options as well for sometime next year. The host site lists a 110/80/16 in the Michelin Gold. Would the rim size on the Beo 200 support a larger size? They also list a Pirelli in 130/80/16 as a replacement for the Beo 200. Can one assume that the rear rim will indeed support a larger tire? I had to lay my scoot on its side once this summer and noticed how fast the front tire broke loose on pavement at slow speed. I was also wondering if a larger front tire would put a bit more rubber on the road, to any advantage. ,,,
