    Default Yamaha FZ-16 Inner Sprocket Change + Tyre Removal

    Main scope of this DIY is swapping stock 14T inner sprocket to 15T (or vice versa).

    15T advantages over 14T on FZ are Great highway cruisability and better top end. Drawbacks would be not so good city ridabilty and need for frequent down shifts and revving.

    PS: Tyre removal part can be skipped. Instead of removing the wheel, just loosen the axle and chain tension bolt, disconnect the stay rod and push the tyre all the way to the front to loosen the chain to remove the sprocket. With this, there will be only limited room to remove and install sprocket. Sprocket alignment may be affected and it tends to wobble. So I personally recommend to remove tyre and do the job. For FZians running on taller tyres (140/70), no other way than to remove the tyre as there is not much clearance with the wheel hugger.

    (Updated pics are from 2 different occasions, kindly adjust).

    Tools required:
    17 and 19 mm spanner to remove rear wheel.
    A 12-13 spanner.
    8 mm and 10 mm ring spanners or socket wrench.

    Parts required:
    15T sprocket from Pulsar 150/180 or Unicorn.
    Sprocket holder (in case old one is worn out at points of contact).

    PROCEDURE:

    Place the bike on main stand, preferably over a wooden plank or tile piece to get better clearance off the ground. Place the bike in gear to prevent sprocket movement.

    Remove the sprocket cover. Use 10 mm spanner for this. Unscrew the two bolts and it will come off in a pull. Now the inner sprocket will be visible.

    Remove the sprocket holder bolt with 8 mm socket spanner (best for this purpose, open-ended spanner wont do, 90% chance of slippage).

    Put back the screw and tighten it and put the chain back over it. (Replace the bolt with an Allen bolt if possible, easier to remove without slippage)

    Hey bro, for removing the rear sprocket from the wheel you said 'pull the sprocket off from wheel'. So is it a press fit kinda thing? I mean are there no locks or nuts to hold the sprocket on the wheel?

    (... Continuation)

    Clean the brake liner and drum before putting the liner back. Use a grease/oil free cloth. Grease the pivot points.

    Install the rear sprocket unit back on alloys, just align and push. Dont forget to put back the spacers in either side or sprocket unit.

    Loosen the chain tensioner adjuster to loosest position.

    Align holes and put back the axle bolt. Bike needs to be lowered for ease of putting back the axle.
    Attachment 47212

    Attachment 47213

    Put the spacer on the drum side before the axle exit the drum side. Align the holes in other side and put the nut on the axle bolt, but dont tighten it.
    Attachment 47214

    Attachment 47215

    Fit the brake connecting rod first, before connecting the drum stay.
    Attachment 47216

    Tighten/adjust the chain tension adjuster nut to attain recommended chain slack. It should be equal in both sides to maintain alignment.
    Attachment 47217

    Attachment 47218

    Tighten the second nut to secure the position.
    Attachment 47219

    Tighten the axle nut.
    Attachment 47220

    Check for sprocket alignment by either manually rotating the rear wheel in neutral or by running the bike in gear.
    Attachment 47221

    Fix the sprocket cover and adjust the brake. Lube the chain.

    Would asking for the price of the replacement sprocket from p180/unicorn be in violation of rules?

    And I think the name of this thread should be "Yamaha FZ inner sprocket change and rear tire removal" as it encompasses both aspects.
    A good long ride can clear your mind, restore your faith, and use up a lot of fuel.

    Rear sprocket is bolted on a base, the whole unit is pulled off from the wheel. Its secured by 4 rubber bushes (damper clutch). To remove rear sprocket from that base, gotta remove 6 nuts securing them.

    Still for info, it cost 54 rs for Pivo branded one. Not all shop sells sprocket alone, most of them sell them as chain-sprocket set.

    I am sorry if my understanding is wrong.

    Inner sprocket means the front side GB (gear box) sprocket , right ?

    If you gotta replace only the front sprocket you don't have to take so much effort.

    You will just have to remove chain lock and pull out the chain, replace the front sprocket, put back the chain and its lock. Its a matter of 10 or 15mins provided you have right tools. Your rear wheel will be untouched.
