R1_Singapore, what do you mean by loosing power?
If you mean losing power after you tried to use the clutch to pull wheelies, then you wasted the clutch and you need to replace. My bike has a little over 3000miles on it and I allready have to change my clutch, this is just a reminder that if you are going to use your clutch to wheelie, you will have to replace it more ofter than usual.
But, if you are refering to losing power in some other way, please be more descriptive of what you are feeling, until then :rock have fun on first gear wheelies.
Mobius, first of all, try opening the throttle at 4000rpms, second, you have to twist your wrist faster than what I am sure you are doing. Accelerate slowly to about 4K and then whack it open, try paracticing little increments of whack speed, you dont want to flip it back the first time you lift it off the ground. You should have no problem at all doing first gear wheelies on an R1.
Actually for all those wanting to wheelie in 2nd gear, you should be able to do power wheelies in 2nd gear.
Try this: After you learn how to do power wheelies in 1st gear, try reving it up to about 6K in second (sit as far back on your saddle as possible) then decelerate fast, letting the front shocks compress, as soon as they bottom out, whack the throttle open just like you did in first gear, the front wheel will lift right up and you will be able to ride it further and faster than you ever did in first gear.
After you learn that, we can discuss shifting gears.
Have fun and be safe, I hope this helps :thumbup
