Set? or Check? If you have to set the timing, there may be other issues that need to be addressed. To "Set the Timing" will require you to remove the camshafts as you would in replacing the shims for a valve adjustment. Please understand that I am not a mechanic, nor do I own a FZR 250, and I do very little work on my own bike. The concept is the same although the application may differ a little in translation from a FZR 1000 to a FZR 250. First you'll need to make sure the #1 cylinder is at TDC (top dead center) You can verify this by removing the.........(Well, as I double check the manual that "I" have which covers the 600/750/1000 differs so much between the 3 that I cannot tell you how to do it with any certainty.) Basically, you need to look at the ends of the cam-shafts and locate an identifying mark, such as a punch. There should be a corresponding mark on the cam-cap as well. Make sure that all marks line up and that the cam-chain has a black link (maybe) or an identifyable link at the top, in the center, between the two cam-shafts. If all of these (I hope) conditions are not met, you have to determine WHY and then repair. I hope this information is helpful in some way and does not cause you any grief. Please check all findings with a Qualified Mechanic or service personel.
basicly I have just replaced the motor in my bike as the old motor threw a conrod. the new motor doesn't have the coil or the bit that spins around it so im transplanting them across.
if you are talking bout the ignition timing- you shouldn't have to touch it. just bolt it all together how you found it and let the little black box do the rest...
