Hello forum,

I was wondering if anyone could help answer a ? I have about a severe wobble while doing stand ups.
When I am wheelieing near the POB or close to it, the bike has a severe side to side wobble. (Almost like how a fish swims.) It seems worse when I'm over 100mph. But, when I lean forward and have to apply throttle to keep the front up, it does not do it. ( Or at least very little)
I tried changing tires, concentrating on foot peg pressure, checking the steering head bearing adjustment, and the wheel bearings. Everything seems to be a go. I do have, however, a small amount of play from side to side in the swingarm. I'm under the impression that all swingarms have a "small" amount of play due to the roller bearings.
I was wondering if anyone has had a similar experience, and if it's a mechanical problem, or just technique. :?

Try being smoother in the throttle. It happens to me too. I can usually make it quit by bring the front down till it smooths then bring it back up like you were saying. Try letting more air out of your tire too. I get it the worse when I shift in the wheelie.

Theres a couple of things that ive learned in this erea. Ive noticed that if the tires are worn in the center they almost always do that. Like TDawg said work on throttle control. Something else comes to mind too, if the assphault is bumpy or rouph your gonna get that. I have noticed that you will do it more too if your getting the bike too upright and that can be costly if your doing that. Hope this helps im by no means an expert but my longest is around a mile :wink:

Pavement, tire pressure. weeeeee

I was out practicing tonight. I think T-Dawg is right! I've been very aggressive with yanking up the stand ups and that seems to make the throttle control more difficult. I've been practicing in 4th & 5th w/o the clutch. So, when I try them @ slower speeds & lower gears, I overcompensate, and the bike snaps up much faster... therefore, I have to compensate with the throttle more to steady her. and that's when I notice it more.
I was very light on the throttle movement tonight, and pulled out a couple of milers to mile & a halfers, Rock solid!
Any other opinions will be greatly appreciated, nut I do believe that T-Dawg nailed it! Truck, yes you are right too! Bumpy roads are a mutha, as well as the near vertical wobbles.
Wheelie, What tire psi do you reccomend? weee Thanx dude!!!

Max pressure seems to make wheelies sensitive to the road for me. Try 26psi and go up. weee

Thanx wheelie!
This is why I love this forum, good people.

I didnt read your post clearly, you have play in the swingarm? yikes. thats your problem. weeee

low air pressure in your tires is your key man.

also, lean back more. if you are using that much throttle, then you are too close to the tank. let your body counterbalance the bike. use the back brake if you get too far back.

so the loose swingarm is no concern? weeeee

I'm with wheelie I think this may be a problem, I don't have any play on my 54.

i don't know what he is talking about. How did he figure out how his swingarm is loose?

I think a.j. was seeing some side to side movement at the pivot at the motor.

Yes, side to side play is what I'm talking about. I'm talking about less than maybe 1/32" if you hold the bike and put pressure on the tire quickly, side to side you can get it to move a little. (You can feel some minute movement.) I can't physically see anywhere that the swingarm is loose or moving at any point.
I was out trying stand ups with 36 psi in the rear tire, and smoother yank & throttle, and it seems to be much improved. But, I do feel that there is something out of place, still.

36 psi is alot try a little lower and se what that gets you....

Whoa... 36 psi? Let out at least 10-12 psi. My tires last a lot longer with lower pressure. I don't get the bald narrow strip down the middle as bad... on my tires that is. :D

I'll have to give the lower tire pressure a try. I have tried the steady throttle and being cautious about how & where i yank it up. It seems to have helped a lot!

lean back more. just stay on the back brake....try slowing them down.

I've been very aggressive with yanking up the stand ups and that seems to make the throttle control more difficult. I've been practicing in 4th & 5th w/o the clutch.

5th gear stand ups w/ out clutch? lol ok pal :roll:

"5th gear stand ups w/ out clutch? lol ok pal "

I guess you have never tried it, or you are not an experienced rider. I can do it @ 145 mph in 5th. (NO CLUTCH) Just lean back hard, throttle quick and yank... trying to touch the shoulder blades together, pulling with your back! The air pressure is a total bitch... and forget about going around a semi, it'll make balance a real fucking nightmare. I said I was "working on them" right? I have a problem with balancing with the turbulence. If I correct with the throttle too much, it drops the front way too fast and it does'nt have enough power to power it back up again. 4th gear... NO prob whatsoever. Give it a try, show some nuts!!!
BTW, that was being done with a 41 tooth rear sprocket, and a 16 tooth front.

Anyone else in the forum try this yet? 4th gear? 5th gear?? 6th gear pinned over hills, 160+ ??? We all know Snigg never has. :wink:

dont fill this forum with your bullshit. 5th gear stand ups at 145mph, give me a break sally.

Sorry brotha.... It can be done. T displayed this last season on his Gixx1. Not that hard, just takes some nuggets.

I'm working on my wheelies, but the 1000RR is my first bike. give me a month or two I might be able to land those.

rev to 9 grand and dump the clutch make sure your in first gear :eek: :D

Poser,

Take it from me... don't rush yourself. work on the wheelies a little at a time. The idea is to be good at it, not to rip out a sketchy trick. Wheelies take time to master. The point is to practice in your comfort zone so you can ride another day.
Keep practicing!!! :!:
