If anything in this guide is wrong can someone post up because i do not want anything bad to happen to anyone who uses this guide but it did work fine.
First remove your front and side fairings. remove your tank, airbox, ignition coils, lower the radiator and remove the head cover.
To look something like this.
Now undo all the bolts to the left hand engine cover so your able to turn the engine to check all the valves. Make sure the pin doesnt fall out of the gear. Unlike my image where it had fallen out.
Now you need a set of feeler gauges I got a set from supercheap for $14 goes from .04mm to 1.0mm.
Next get a 14mm spanner and turn the bolt that was under the engine cover and turn it clockwise so you get the lobes on the camshaft in this postition. (Also on the shafts you will find IN1 through to IN4 and EX1 to EX4) The top shaft in the Inlet valves which when the engine is cooled which is should be for doing this have a gap of .16MM the Exhaust clearance is .23MM.
Place the gauges under the lobes to get the clearance if it is out change to different gauges so you can get the correct clearance so you will know what valve shims to buy. In the image you will see where the lobes need to be to get a correct clearance reading.
After doing all 16 you are left with the math of finding out which shims you need.
Example for an inlet valve clearance you got is .22mm you need .16.
.22 - .16 + 1.98 = 2.04 (1.98 being the size of the shim already installed which on the shim will say 198) The shim you would purchase to fit into the bike would be a 205 which is the closest to 204.
When removing the shafts to fit in new shims undo them in a cross pattern so you wont bend the shafts. With the oil bar throught he middle be very carefull when you take the allen key bolts out and lift it not to lose the rubber seals.
Here is an image of the valve shim put into place then you just put the bucket over the top. (I dont know if it makes a difference but mine were placed in numbers up so I did the same)
Now its time to put the shafts back in and correctly time it all.
On the right hand engine cover you will find an allen key screw a big one and a small one above it. Undo the little one on top and now turn the engine like you did to check the clearances until you see a T written on the metal inside the hole.
When you find it place the shafts like the image below. Make sure both lines with the top one the IN line and the bottom one EX face each other and are parrallel to the engine.
Now place all the holders back on the shafts and tighten in a cross pattern once again. (by cross pattern i mean something like do one bolt on in4 being the top bolt then do up the bottom bolt on in3 holders)
Then put it all back together and you are done.
I know the pics are crap and are from a camera phone but I tried.
If you need any help at all PM me or post here I will help asap.
Here is a link to the album i uploaded if you need more pics.
