This may sound a bit stupid?

Iv'e decided to stick a 14 tooth fronty sproket on for a bit of wheelie practice. Got the sprocket home, bent the lock tab out of the way but the nut won't budge??
Tried with a long bar but still no joy?? I'm trying to undoo the nut anti clockwise. I did try clock wise but thought that can't be right.
Iv'e even had the missus sit on the bike with her foot on the break as I'm just pulling the bike over off its stand. Even when in gear??
So the possible silly question is; How the bloomin eck do you get the bloody nut off?

Anti clock wise it correct, You need to but your bike so that the front wheel is against a wall to stop it moving forward, have the bike on the side stand and stand on the oppisite side, you will need a long bar, now you will have to put one foot on the back brake lean over the bike with the long bar facing the back of the bike so you are going to be PULLING UP, make sure that the socket is on the nut and with a good clean jerk (you might need to do it a couple of times) it will undo. That is how I got mine off once you move it, it come undone easy

They are very tight, I normally use a air gun to get them off & torque the nut back up with a torque wrench.

If you cant get it off spray some WD40 on the nut leave for an hour. You will need two people, front wheel against the wall, one sitting on the bike with it in 1st gear pushing the front & rear brakes hard, place a block of wood or something between the rear metal frame of the bike & the rear tyre this will stop the suspension from compressing, use a long bar on your socket wrench & turn it in jerking actions anti clockwise.

Good luck.

If possible jack your bike up off the ground and then you can sit on the bike, hold the rear brake on and then stand on the end of the bar so that it puts more pressure on the sprocket nut. Worked for me but was a bit wobbley:eusa_clap:

I bought an electric impact wrench from a Saturday market for �5 last year. It was brand new but the plastic case was cracked and so was dirt cheap. The torque wrench to tighten the nut was �8 from the same market. If you go to a few Saturday markets you can get some really good tools very cheap - beware of the 'chocolate' rubbish they also sell.

Superb Gentlemen! The nut is off!! :laughing7: Thankyou!

Now do I need a puller to get the sprocket off as it has two thread holes on it? Or is there one of your experienced methods again??

Cheers,

just riggle it left and right while pulling towards you

For info, the reason it has the two threaded holes is because the same sprocket is also used on the FMX650 (and maybe the dommie), and Honda use a splined plate to hold on their front sprockets - far easier to change the 'long bar/heavy mate' method required for Yamaha (and Suzuki)...

Thankyou everyone! :coolsmiley:
I can now get on with the wheelie practice with the new 14 tooth on.

Thanks again,

How you finding the 14. My bike came with a 16 fitted and I've got a 15 in the garage waiting to go on. It'll wheelie in 1st no problem but 2nd gear is harder. Clutches up reasonably well but struggling getting the balancing point. I'm hoping once the 15 is on it'll come up easier and can concentrate on the balance point.
