unwanted turbo wheelies

[madlyhs]

I would like to know what kind of measures I need to take in order to stop unwanted wheelies. I understand that changing the sprockets configuration might do the trick am I correct? If so what is the recommend sprocket gearing?

I am not so keen on changing the swing arm as I am sure that will stop the unwanted wheelies. Is there any add-on parts that I can use with the stock swing arm to extended enough to avoid the unwanted wheelies?



I am not sure how many of you have two stage boost control but I recommend to install an indicator for the high boost if you have not done so yet.
I discovered that the high boost switch was on (someone played with the switch without my knowledge) and that resulted in my accident as I did not have any visual indication ( just learning from my expensive mistakes

)

hehe, unwanted wheelie.. thats pretty funny.

no ideas other than duct tape a brick to the front fender..

or turn the throttle the uda way ..

sounds like a pretty fun problem.. well unless it happens at the wrong time I guess.

Swingarm extentions, they bolt on . Someone on the board used to sell them I think his name was gsx1300r

Stay of the boost!

18T front sprocket will help... but not too much.

The big front sprocket however forces more of a load, which increases in boost, which further propetuates wheelies.

I feel your pain... on low boost 5-6psi, it's timid at 210hp.
However on high boost... it becomes very violent.

Johnny at Exotic Cycle makes very nice extensions.

Some sort of swingarm extension may be your only recourse...You can go with bolt ons as long as they have double bolts or preferred would be a welded arm...At least four inches and your wheelie issue should be gone...I'm at six an all I do is smoke the rear...

I just stole this off one of Cecils post but I guess he already got to you.( For Swingarm Extensions call Johnny "Turbo" Dorbin at Exotic Cycle.

Tell him Cecil sent ya)

Have heard close reports in my club locally that even the good swing arm extensions still have some vibration in it... Instead of getting the extensions for $300, I would try to pick up a used 4" extended swingarm... I am getting mine brand new for under a thousand and that is a 2-9" extension polished with air shifter bracket, underbracing.... (600 Arm)

Extension is probably the only way to go effectively here.... You have to find the sweet spot for your setup... If you go too long on the extension, you will have a harder time putting power to the ground, the rear will just want to spin a lot... (Not as much weight on rear.) 4" seems to be recommended by most for that setup on the street.

I cant remember where I read it, but putting rear entension on a ""turbo'd"" bike is not the way to go.

Check out some of the dragbike sites to see what the turbo guys are using on their busa's .

my bike is lowered and I have a stock arm and stock gearing and don't have a big problem with wheelies. Rolling 40 mph burnouts are my problem.

Schnitz racing sells the Launch Master. I don't know anyone who has tried it. Sounds like a good idea.

Launch Master maximizes acceleration by monitoring a fork switch to determine if the front tire is on the ground or off. Your bike has reached its maximum acceleration possible when the front tire is weightless on the ground. Launch Master helps you to hold the acceleration to that exact point by cutting the engine power just enough when it is up and not at all when it is down. With proper setup this on-and-off of power is not even detectable. The control module cuts engine power by momentarily “killingâ€￾ cylinders through ignition.

Stay of the boost!

Exactly my thought!

 

[nitrousjunkie]

wish I had this problem!!!!!!

Unwanted wheelies....quit whackin' the throttle so HARD

 

[STUNNAH]

What type of switch do you have for the controller???Mine is as simple as you can get toggle down for low up for high no light...

 

[Uncle Bob]

Yah, I'd have to agree with the "duh" crowd. Stop whacking the throttle where you know it'll come up if you whack the throttle. My bike only wheelies when I want it to, because I know what amount of throttle in which gear causes wheelies.

Its called "throttle control".....and its pretty important skill on a turbo'd bike

Now if you're looking to get down a drag strip faster, thats a whole nother subject, and others have said, a longer swing arm is the best mod you could do.

If you don't want a longer swing arm and you don't want the bike to wheelie while still having fun with the throttle, get a 600. Otherwise learn your throttle and you might seriously need to get a longer swing arm. We have a guy in town here with a 410hp busa and only 2 inch extension on his. I think I have only seen the front come up on him one time and that was during a launch, he might of got about 4" up. Other than that he always has both wheels on the ground and there isn't one of us around here that can beat him in any kind of race ( aside from 1/8th ) yet.

STUNNAH mine is the same  just a toggle switch (two Stage boost control) and that's why I am going to install a light to it for safety. Therefore,  I will know if the bike is in the hi boost cos the light will be on  in case  someone flipped the switch without my knowledge .

I know the limit of my  bike under low boost  and I do  have throttle control ; but  as I said someone played with the low/hi boost switch and I was not aware it was in the hi position  and that is why I had the 90 degree wheelie (it was too fast too late to control) which resulted in my accident .

I only use hi boost when I am in 4th gear onwards and I do not have any wheelies problem at that gearing  .

I guess I must also consider longer swing arm  and check out the Launch Master so that I can be safe all the time .

Thanks guys for your feedback I really appreciate it .

Yeah that is something that I have learned to check prior to every start up the position of that switch...Folks hang around our bikes and they may actually touch something that we don't know so it's always good practice to recheck anything that can be touched...
