    It's just the new pads bedding in, it'll go away.

    You should replace the chain and both sprockets ASAP. The stock sizes are 17 tooth front, 56 or 57 tooth rear, and the chain size is 428. Buy a new crush washer for the front sprocket as well.

    Your bike appears to be a 3LN1 which means the readily available aftermarket sprockets will fit without an issue. If it ends up being a 3LN3 or newer (some has changed the front from single headlamp to dual headlamp) you need a 2mm spacer on the inside, or buy the correct sprocket from Litetek: http://litetek.co/Sprocket_Drive_Yamaha_FZR250_3LN3.html

    Make sure you select 17T front an 57T rear.

    Forcing the caliper pistons back should put the fluid back into the reservior or you can crack the bleeder valve & let the fluid out that way.
    The pistons in the calipers might be a bit stuck / sticky, they might free up, they will definitely work but might drag a bit. Keep checking the front wheel & make sure it isn't sticking / draging & if it is you'll have to strip the calipers & clean them up. Its a simple job & install a new caliper seal kit while your at it.
    Oh the joy of owning a bike, you gotta love it !

    When I changed the pads I pushed out the pistons in calipers because there was meat left in the pad and I cleand all the surfaces very well and took off majority of corrosion. The pads have freed up today I had to drive to town and I was able to push the bike freely while sitting on it I couldnt yesterday.

    Im 99% sure the bikes 3ln1 I will count the teeth on sproket but ive ordered that set on ebay now. So with any luck its the right one. I havent had the chain off yet or anything would it be bad to reuse the old washer?

    Thanks for the help guys its really appreciated :)

    It most likely means a previous owner has changed the sprockets and chain to a 520 size. There isn't really a problem with doing so, as they are generally more available and in different sizes.

    However the larger chain and sprockets also means the engine has to work harder to move it.

    The designers chose 428 chain size for a reason

    That is not close to being right for the bike ..... what you have ordered is correct.

    Clean up all the crud before reassembly ..... you can reuse the lock washer , just flatten it before u put it back on and try and use a different spot to bend up the tab to lock the nut.
    Don't forget to loosen the front sprocket nut first before u remove the rear wheel and chain.

    The chain may be longer than needed and require a few links removed .... the wheel needs to be as much forward in the swingarm as possible with the new chain to allow for stretch and adjustment rearwards over time.
    With the chain adjusters on the ends of the swingarm you have to get a balance between the right chain tension and the rear wheel alignment...... u will see markers on the outside of the swingarm to get the wheel aligned straight.

    The closed end of the link clip should face the direction of chain travel

    Torque setting for rear wheel nut is around 100Nm ... in other words ..very tight.

    Being that far off how would that change the characteristics of the bike gear it down?

    Ok will do yes 100nm is fairly tight I might just borrow a torque ratchet then as I know to tight and it will impead the free spinning of the wheel.

    Link clip towards the headlight gotcha :)

    Is it hard to take links off? Ive never had the pleasure :-/

    As always mr grey your knowledge is proving invaluable to me!

    It's not hard with the right tools, that being a chain breaker kit. Your local motorbike shop should sell them.

    You can grind the heads off the pins & knock them out with a punch
    Most new chains come with circlip joiner links these days, easy to install

    Your front sprocket looks 'thick' ... as in the ones used on a 3ln3 and above

    Forgot to mention linkin that company you linked me doesnt post to ireland. Will the new chain and sprockets make my bike have less acceleration due to more teeth on them?

    Gearing can be a little complex at times ..... try this
    For general riding I cant see much point in changing the stock setup.

    The problem also with a 'small' front sprocket is the chain scraping on things it shouldnt.

    Strange the motor hasnt a number .... if its not near the clutch cable its usually at the front near the headers.

    Your frame indicates 3LN1 but the motor could have been swapped out
