front sproket removal

[scottyhatchi]

Hi everyone i was wondering if anyone has ever had to remove the front sprocketr from a kawasaki zx9r before ??
my friend having problems removing it doesnt know how to do it and a mate of his said he needs a windy gun surely there is a way to get it off without a windy gun ?

Put the bike in first gear and use a long handle on your socket ratchet for leverage and try cracking it undone.

and it wont cause any damage doing that while its in gear ?

+1 on putting it in gear

Try using a long breaker bar (2' or 4') and have someone stand on the rear brake or put a good sized lump of wood in the wheel / swing arm.

Make sure the bike doesn't rotate and fall over ;)

Be carefull you don't round off the nut....

[scottyhatchi]

so it is safe to put it in 1st gear then ?

so first gear wood in swing arm long bar and hold the brake ? lol

Yes it's safe to put it in gear. One of you stand on the back brake pedal as well. Then either use a torque wrench or breaker bar. Make sure you bend back any locking tabs that may be on the nut first

...and 27mm is exactly (well to 1/100mm) 1 and 1 sixteenth in imperial size, so if you've not got a metric socket or spanner look in your old imperial toolbox...

okay we now have another problem ... just been informed the chain was grinded off so the bike doesnt have a chain so all the instructions in wat to do seem like they cannot be done now .. any ideas ?

[VTRDark]

Putting it in gear should still work but you have now lost the back brake. and made it twice as hard You could put the new chain on and then use the back brake to help remove the the front sprocket and change it for the new one. I think you need to have a go at undoing it first, it may, if your lucky, come off reasonably easy with it just being in gear and some good leverage.
