Hi ........... One tooth less will give you more top speed (if you can pull top revs) but will reduce accelleration. If you go for one tooth less you'll need to tighten the chain and/or remove a link. It's a trade off ............ decide what you want the bike to do.

hi,normal way to set up fz is as follows,remove left hand engine cover and you will find cdi picups with a backing plate and interrupter tongue,remove all the spark plugs(dont get the leads mixed up),turn the motor by hand up to top dead centre on no1 piston,the tdc mark the plate will line up with the cdi pickup,no1 piston will now be at tdc,both sets of valves ex and intake should be closed and the tappets slightly rocking,if thay are not and any of the valves on no1 piston are open or tight,look to the end of the camshaft (where the cam fits into the bearing surface)and there will be a horizontal mark on each camshaft,release the cam chain tensioner,slip the camchain off the sprockets and rotate the camshaft untill the marks on the camshaft are exactly parrellel to the rocker box mating surface,fefit the cam chain and check alignment then retension the adjuster and check the marks again,if you have it right the marks should still be exactly parellel with the rocker box and the piston should still be sitting at tdc,if it is out by 1 tooth do it again untill it all three marks are exactly right,failing to do this WILL result in a valve sailing through the top of a piston,then it becomes a bigger job again,after you have got them adjusted correctly ,turn the motor over by hand to check that nothing is binding,if you are satisfied that everything is right,then use the starter and you should have compression,hope this helps

Just remove the chain cover then bend the tab on the lockwasher away from the nut so you can then remove the nut. Install the new sprocket and put the assembly back together. Stock gearing is a 13 tooth front sprocket and 48 tooth rear sprocket. The stock chain is 112 links plus master link. The chain is DID 520D 112L. Please rate my answer. Thanks.

This is just a guese ive never worked on a R1 but most bikes are similar with chains.
Firstly to loosen the axel and the chain tightners and pull the wheel as far foward as you can. then to find the master link in the chain its a funny looking link with a clip on it, it might not have one if its a compressed link chain, but for this sake lets hope you have it, when you find it use some needle nose pliars and take the clip off and then pull the link outwards it will come off like a washer and push the other side out, theres the chain broken so it can come off, its its a new chain your installing you could cut the old chain off with a hack saw or grind on one of the links. as long as the new chain comes as one long peice not a circle with no master link.
to get the sprocket off the front find where the chain goes too and un bolt the cover for it it should not be water tight. then the sprocket will have a Circlip or a bolt on it, if its a circlip get a flat screw driver in the space and turn or use the right tool. if its a bolt nock it in gear and try to undo it with a ratchet if it just turns the engine you will need to undo the timing plug on one side of the engine and put a ratchet on the flywheel while un bolting the sprocket you could also do this while the chain is on the bike and put the rear brakes on and un bolt the sprocket, this will stretch the chain but your changing it anyway.
new sprocket is same way just slide it on and clip or bolt get your chain all the way around all sprockets and the master link will probly be an O-Ring chain, if so you need some vice grips and a 8 or 10mm nut or a 1/4 american nut and you put the rubbers on either side and the plate
and put the nut over the link heads and clamp down til the clip slots are showing do this to both sides of the link. then put your clip on with needle nose pliars and pull the wheel back with the chain tensioners and tighten your axel
you want a bit of play with your chain so it can stretch when you sit on the bike, you will need to tighen it for a few hundred miles dayly while the chain stretchs and wears in.
