^^^^^^^^^ Let us know how you go with that project. Very interested!!

I might make a tutorial up on it. Just will take a bit of time as it's a big job. Pretty easy to do the timing though. Same principles apply to most engines.

 

[mini mullisha]

to set timing:
is a little mark on top inside of ignition/flywheel case and on side of cam casing,right side at bout 9 oclock.
Need to set fly wheel d/t/centre with mark on fly wheel to mark on caseing.
And also set cam sproket to mark on cam case,is a little circle on cam sproket,they must be lined up, with flywhell dtc.thats how i done mine,im no mechanic but bike gos!!haha
any1 got anything else that may help feel free to add!

hey sorry i dont quite follow. So i got to take crank case off? and there will be a mark on a fly wheel? does that mark have 2 line up wid sumfin?
then wat? wats the "d/t/centre" mean?
another thing i dont get is, when i took off the cam wheel, i forgot what position the mark was in. So does it matter, is there a certain spot or way to tell if the cam wheel is on properly be4 u line it up with the other mark??


please help =s

by d/t/centre he meant Top Dead Centre (TDC)

there will be a mark on the crank casing that should be marked with TDC, that needs to line up with the mark on the sprocket... this is hard for me to explain cause i dont really know what any of these parts are called, i just know how to do it..

do a search on here for the thread that tells you how to set valve clearences, because it explains how to get the engine to top dead centre and has pics i think. otherwise search google.
