wheelie
 

I have a 93 cbr900rr in great condition- it runs extremely strong and loves to wheelie in first- it will come up both by gunning it and popping the clutch. But for some reason it just wont come up in second. I'm sure its not the bike, its probably me but i dont know what im doing wrong. How fast should i be going in second? what should i rev it to before popping the clutch? will it come up by gunning it, letting off, then gunning it again at high rpm? Should i slip the clutch or pop it out as quick as possible? Do i need to pull up? Do i need to move to the back of the seat? Like i said the bike runs extremely strong and is very fast, i've also dropped a tooth on my front sprocket so i dont think its the bike.... is it? does anyone know if a 93 cbr900rr even WILL do a wheelie in second? Any help would be great guys! thanks!

first, i think everyone on here might get on you for "stunting" with all questions regarding stuntin either just pm me or join stuntlife.com, and when you are in second atleast on my 900 with the 520 chain i rev it up to about 10 grand and drop the clutch and then THROTTLE CONTROL, thats all i can say. just be careful cuz it throws you off guard the first couple of times then you get used to it, cuz you feel like you are going to fall off but really you are just falling into balance point and you will then feel weightless and ride forever or until your carbs start coughing :) :) :). good luck let me know how you are coming with it :)

Stolen from someplace..................


First of all, I learned all of this from my own experience and from the advice of others on this forum. Following this advice won’t keep you from crashing, getting hurt, and breaking stuff; but it will, most likely, help you learn faster while crashing less often than if you figure everything out on your own.

Bike setup for wheelies

Oil: Many bikes will become oil starved when riding long wheelies, and doing 12 o-clock wheelies. Gixxers and cbr 900s ('93-'95 893cc model) are the most notorious for this. To keep the bike from becoming oil starved, either move the oil pickup in the oil pan back, or overfill the oil. Myself and some others on this forum run 1 quart over. Overfilling doesn't seem to cause any problems with hondas, but I have read of problems with gixxers as a result of this. So the best thing for a gixxer would probably be to fix the oil pickup. You can buy modified oil pickups for gixxers from www.stuntex.com .

Gears: For learning, gearing the bike down is unnecessary. Almost every sportbike will wheelie in first gear without any problem (maybe the ex250 is an exception). Also gearing to make second gear come up easier is kind of pointless because it just becomes more like first gear with big sprockets. If it doesn’t wheelie in first gear, it isn’t the bike’s fault. For the most part, gears are unnecessary until you are ready to learn highchairs (on a weak 600), no throttle hand wheelies, and circles.

Tires: When doing high-speed wheelies make sure you have a good rear tire. A tire with a flat spot in the middle can cause wobbles. I learned wheelies on a rear tire that was almost down to the cords in the middle, and it would often wobble like crazy when doing balance point wheelies. A new tire almost completely eliminated that problem. Run the tire pressure lower than stock. For doing wheelies above 20 mph, have the tire pressure between 20 and 30psi. For doing wheelies slower than 20 mph, lower the pressure to between 12 and 20. 18-20 psi makes for a good all around psi. Lower tire pressure makes the wheelie more stable from side to side.

Tip over sensor: Most (or all, I’m not sure) bikes with fuel injection have a tip over sensor. This can cause the bike to shut off when riding wheelies high. This should be disabled. For Hondas this can be done by cutting the wires going into the sensor, connecting the two outer wires, and leaving the middle one hanging. For gixxers, that method doesn’t work. The brass ring in the sensor must be removed, or immobilized with something such as silicone.

Steering Damper: While it isn’t imperative that you have a steering damper for doing wheelies, it might save your ass. If you come down from a wheelie with the front wheel crooked, it could cause a tank slapper. This shouldn’t be a problem, though; if you make sure the front wheel is strait when you put it down.

Exhaust pipe: If learning 12s, the pipe may have to be shortened. The stock pipes on some bikes touch the ground at about the same time as the tail when doing a 12 o-clock wheelie. If the pipe hits the ground, it may cause you to crash. My friend just went down a week ago because of this. The pipe can be shortened by simply cutting a few inches off the end of the pipe, and then re-welding / re-riveting the end of the pipe back on. Short pipes can also be bought from www.starboyz.com.

Cage: In the process of learning to ride wheelies good, you will most likely drop your bike. Crash cages provide the best protection. All of these cages will most likely save you a lot of money if you crash, but none of them will completely protect your bike in every crash. Here is a list of some crash cage websites in no particular order.

RE: wheelie
 

Thanx for the info there, I might just give wheelieing a try. I've managed a few before on my previous CBR125 but not yet on my CBR600FY. I managed to wheelie by going from a stand still and just giving it berries and dumping the clutch. Though they were hardly what i'd call proper/controlled wheelies, but by fluke I managed some nice small ones. Though one ended rather disaterously on my old 125 when I dumped the clutch at 9,000rpm, I ended up getting thrown into what could probably have been an ace 12 if I knew what I was doing, but alas I didn't lol. So I bailed off the back, but kept hold of 1 bar, which happened to be the throttle :D What followed looked much like me dancing with my bike as I tried to grab the clutch being as once again I didn't know what I was upto lol. After failing to get the clutch, still holding the throttle. The bike ended up going up and down, up and down, dragging me around with it for a bit, then finally it came back down and landed with the bike upright with me next to it, but as I was off balance it fell onto its right side, flipping me across the bike as yet again I held onto the handle bar, sending me commando roll style over the bike. Needless to say I felt like a prat, after checking out the damage i'd managed to smash my rear light casing, crack both rear side cowls and my learner plate and put a slight bend in my brake lever and grind some rubber from my throttle as i'd got my bar end off on that side at the time lol. Thankfully the cowls only cost around £40 each and the light cluster was under £20 and a new throttle grip was about £12. But the dent to my pride and the story to tell was priceless:D lol.
