I have question,

I have a CBR 929 and I want to learn some new tricks..
I can do now tank wheelies and high chair wheelies
regular wheelies and standing, standing on the passenger steps and the can can.

But i want to learn more..

I want to learn 12's
So what must i do to prepare my 929..
I have just orderd a crash cages and a 12 bar at FI
What tire size is the best? I know have a 180 at the rear.
How much bar/psi must i put in it?
sprocket size front and rear?
do you have to change your idle?

please help me

 

you really dont need to change anything. Most of us learned to 12 on a stock bike with stock gears.
I think it's a bad idea to learn with a bar. Everybody wants to go out and scrape tail, but that's not the idea. learn to wheelie slow, get your brake control, then if u wanna do bar tricks or go REAL slow, get gears and a bar...

 

And tire presure? isn't that important to stable it?
I know have one size smaller at the rear for better handling in corners but i think a 190 is better and more stable because it wobble's when i'm doing 1ste gear wheelies with back brake.. i can keep it at a constant speed. But the back brake also heat's up and go's fading.. (my english is not perfect)

 

What can i do about that?
Diverend brake fluid?

 

lower your pressure.....like 10psi

leave your back breaks alone until you have a problem. no reason to fix something that isn't broken. stock pads work best.

read all the posts you can find on 12's...there are hundreds of them on here. that will help. also watch videos.

 

To answer your question run a 190 rear with your pressure at about 15psi, thats what I do. I haven't had a problem with fade. Maybe you need to ease up on the rear brake, I feather the brake lightly, but that fawker gets hot as hell though. I tried to let more air out of my tire once after a few runs, hit the rotor with my glove and it melted my glove and burned the shyt out of my hand.

 

Thanks..

Tommorrow i put a 190 at the rear..

I had read all the 12 topics now..

Thum brake do many install that?

and ow to install that what is the best way?

when you do high chair 12's does it go's back by engine brake because some use really big sprockets or do they use a thum brake?

 

Thumb brakes are becoming more popular. People do highchair 12's with a thumb brake or engine braking..can be done both ways.

Don't get ahead of yourself...go learn them 12's first.

 

ya, if you aren't doing 12's and slow stuff, you do'nt need to be worrying about thumb brakes and scraping highchairs.

also, most people run 180's. more common tire and i noticed they flex less than the 190's and they cost less too.

 

I agree with less flex, but to learn just the regular 12 or slow straight wheelie that 190 will be easier because you have a wider platform to balance then when you come into circles and the similar stuff later that 180 will be the choice tire plus you will run more air.

 

Is a thum brake handy for learning 12's

because i have i problem holding my foot at the back brake..
while wheelying.

Or is it just something you must get used to..
So practise more with holding my foot at the back brake.

and we don't have lbs here in the netherlands..
only Bar and Psi so i don't know how much 15 or 10 lbs is..

 

Get use to the foot brake first. Run the tire almost flat.

 

first thing is really listen to what these guys are telling you. i just got 12 and rolling a slow wheelie consistant after 2 months or so of trying and constantly crashing. definitly go with a cage, i didnt have one my first 12 crash and regreted it all the way to the bank and the local dealer for parts. you have to snap it up real quick then stall it, if you have your idle at like 3,000 rpm's this is easier b/c you dont have to play with the throttle as much and wont be as choppy(learned this the hard way). stay on the brake all the way up and just get used to how much you need to keep it up with out slamming the front end down, wich you will do(blew new fork seals in 3 weeks learning this). once you get that you will be able to set that bitch down nice and soft on the bar and ride it out. then you just give it more(smoothly) back brake and your back on 2 wheels. one more thing....make shure your back peg is good if your doing it switch foot, mine snapped while i was on the bar last night....NASTY...bike flopped on to the 905 cage and drug me like 20 feet....the boys tell me it was funny to see(they were laughing so hard they couldnt get a picture off.)oh yeah....15psi in the rear and 2 up sprocket, stock brake pads. get ready to trash your bike.

 

Back brake first or you'll never be pimp with no handers.

 

lbs is PSI. that's just how american's say it. kinda slang i guess.

and you have to learn your rear brake. you should be using it on the street too, it's 30% of your braking, get used to it. it's a very essencial tool and your foot should be over it all the time just in case you go too far on a highway wheelie, it'll save you.

 

thanks..

so it is 10 to 15 psi then..
thanks..



I use my back brake a lot..

I also race Supermotard and there you need a little back brake and engine brake to slide it in..

But when i wheely i have trouble to use my back brake..
my foot automaticly go's of the brake..and slide next to it..
But i will parctise on that..


I now have 1 down and 4 up..
that makes a lot of diverens.. much more engine brake..
I like that a lot already.. tonight i will try the back brake.. it's here now 17.05 PM..

But i will wait for my 12's when i have mounted the cages that i ordered..

always have your foot on your brake if you are using it or not. even on highway wheelies. if you hit a bump and it goes too far, no foot over hte brake, you are going down hard. #1 rule is to cover the rear brake.

 

I had practised the rear brake this evening and it works now..

You just getta used to it..

Now i have constanly have my foot at the rear brake..
thanks for the tip..

and i also tryed 15 psi..

it is far more stable but it is harder to steer during wheelying..
So when i practise slow wheely's i will lower my tire presure to about 15 psi..
and on the way back pump it up to oubout 25 psi at the fuelstation..
then it's more easy to switch lane on one wheel

But the rear brake is great..
a view times i only worked the brake and diden't need the trottle..
It feels like you flip it but you won't

 

tomorrow i will put my idle at 2500..
and will work with that..
i will try to only work the back brake..

 

try moving your right foot a couple inches forward on the peg and point your toes in a little. it feels a little akward at first but it makes things a whole lot easier for brake control.
