SOURCE: Vibration at 2900 RPM

I have the same problem with my Roadking except it wasnt dropped. I did a full alignment of rear tire to engine, aligned the rear tire to front tire, aligned the engine and replaced the front motor mount. Nobody seems to have an answer, that I've talked to anyway. If you find a cure let me know, If I find one I'll let you know.

Hard to diagnose, but if you have a bad engine vibration, you will be able to diagnose that when stopped and just revving up the engine. Moving balance problem can be easily out of true wheel and or needs balanced. (You can make your own balancer/ wheel true guage our of a couple of 8X8 posts with axle size hole drilled in each one) If you clonked a curb or pot hole at speed this can easily happen. Hope this helps you with your scoot, Rick

SOURCE: front end vibration

One thing you could try is a "fork brace" or what some people call a "tweek bar" that ties the two sliders together. This reduces the amount of flex in the front forks. We used to run them on our dirt bikes years ago. They do help stabilize the front end.

Also drop your front tire pressure to 30 psi and look for any unusual wear patterns on you tires such as cupping. Take the wheel off and have it spin balanced as well. You can also change the fork oil in your forks. I run PJ1 30 weight in my Wide Glide. It's a bit on the stiff side but it sure helped the handling as the bike no longer bounces and dives in the turns. I also got away from the Dunlop tires. I now run Metezler 880's and they seem to handle the turns better but I think the Dunlops had better braking characteristics.

Good Luck
Steve

I got a 1989 big bear it pulls to the right i put new tie rid ends and upper and lower balk joints in pulled cv axel it seems to be ok steering bearings seem fine also anyine have any ideas

Try aiming the handle bar straight and pull some kite string across the rear wheel , lightly touching the sidewalls of the tire. With the length of the string pulled across the front tire, adjust the outer tie rod so as to make front tire lightly touch the string. That should square the front tire to the back tire. Once the front and rear are squared, adjust tie rod in 1 turn for a slight negative toe. Do both sides while making sure to keep the handle bar straight during string and adjustment. That should help.

The vehicle has a vibration felt in the seat and body of driver as the vehicle runs at high speeds. The problem seems to have started about the time I had new bushings put in the front stabilizer bar but...

Is it only at high speeds or all the time? At high speeds 60mph or above it could be the tire is not balanced properly. If it is felt all the time you could have a bent rim. If the tires are cupping it means you have faulty front end parts or the camber/ caster needs to be adjusted.

I have vibration in handlebar and pegs. My girlfriend complains specially about the vibrations in the passenger pegs. ¿How did this bike got the approval to go out in the market with this terrible...

for starters, make sure tires are properly balanced and inflated to proper tire pressure. as for the vibration i the pegs, that is normal. if it's excessive, make sure subframe boltsare tight. gixxers are know to lose one or two ( locktite on the bolts is very helpful). good bar ends are very helful in reducing the vibration in the handlebars.

Front end vibration

Check if there's any play within the bearings..top and bottom of the triple tree. Put your bike on the center stand and ask someone to sit onthe bike seat and tht way it will raise in the front, try to shake the triple tree into forward and backward motion, if you do find some play thn try to adjust them(bearing)...careful not to keep em tight or else you wont get a good balance on the steering whiles riding!
Check the bushing at the handle bar too!
Hope this helps!

Vibration felt in front floorboard

Yes it can but the dealer would have found it on the test drive if they test drove the vehicle. The only other causes for the vibration I can think of should have been found on inspection as well. Check your bushings and mounts for the sway bar and your tie rod ends as well.

I have a 1982 V45 HONDA SABRE VF750S motorcycle. It has a severe front end shake if you remove one hand from the handle bars. What could be the cause of this shaking?

I had the same problem with mine last year. I put a new tire on it and had it balanced. The vibration went away. I would at least have your tire balanced.
