yes, that was not a good day, was even worse having to nurse it home like that for 5 miles, had to go from 1st to 3rd as fast as possible if i needed to stop, if not it tried to keep it in 3rd and hope that nothing tried to lodge itself anywhere...

its not just a problem for high torque bikes, my zxr400 managed to - under hard acceleration - snap a tooth clean off the 2nd gear input shaft...

better to get these things sorted sooner rather than later...

cmsnl prices are the same as here in the UK for piston rings...ive just bought 4 along with a top of other parts http://www.cmsnl.com/yamaha-fzr1000-exup_model16740/ they should do shipping to norway. if you replace the rings get the barrels honed to allow the rings to bed in properly. you might wan...

plug #1 (the leftmost one) looks rich, the middle two look fine, the right hand one might even look a tad lean - ceramic looks quite white, they should be a nice tan colour like the middle two.

tight inlet valves can also cause you to blow fuel vapour upwards if you dont have air being forced into the cylinders...i would check you valve clearances, inlets especially. as for the fuel leaking its either what don said - knackered fuel float, or your floats are set too high so they dont have a...

the 1040cc kit means you are pulling in 3.79% more air than before...i think the airbox can cope with this engorging process.

its for my near-mint condition bike, so it will be proper or not at all

cheers guys for the informative responses, hmm 3cm shorter than the zxr ones, and with my 54" chest i already have a good view of my elbows :D also my current ones are black so i cant change the bottom of the mounts over...bugger! my zxr400, even though its my commuter bike, is almost back to standa...

i have lapped all of mine in now, you need to do it until solvent doesnt leak around the valve face...and repeat x20 :D then give it a damn good clean, you dont want any bits of lapping grit getting into places where it isnt ment to be. at the same time, replace all of the valve stem oil seals for n...

hi guys, i have a zxr400 and i want to fit white mirrors to it, but i cant find any in stock anywhere for less than £120 for the pair! so i dont think that these would look too bad from a fzr 600 (they are round, whereas the zxr ones are square, but i can always re-sell if i dont like them in a few ...

my 1989 strainer looks like this:- http://img.photobucket.com/albums/v633/Banner001/2013-03-06231353_zps111430e8.jpg there are o-rings where the pipes enter the engine, but no gaskets. the actual strainer is clipped onto the main metal housing, and can be removed. you cannot remove the metal mesh as...

new valves will also require at least lapping, possibly need all the valve seats re-cutting as well.

when i get mine back from being refaced (middle of next week) ill post up the lengths.

from memory all exhaust valves are the same length, and the 125mm length seems way too long, even for the middle intake valve...

carb intake restrictors (on most bikes) go somewhere between the bottom of the carbs and the engine intake rubbers. on the zxr they are washers that are placed just underneath the carb inlet rubbers. the snorkels job is (i think) to smooth out the airflow entering the airbox so that its all laminar....

the exup servo doesnt run on battery power...it run on love.

flat battery, it should still work.
