Hey,

we need some help on adjusting the valves and springs on an '88 Hurricane 1000. Our question is when doing the adustments on the valves to get correct spacing measurements, cylinder one and four were on top dead, but 2 and 3 were not. Do we need to adjust 2 and 3 to their own top dead to get correct valve measurements or can we leave it at the top dead on cyl 1 and 4?

Same as a car, if your cylinders are at DTC then your valves are closed and you can adjust em, if there open then you cant adjust.

 

you can do half of your valve clearance measurements at tdc for 1 and 4, then you need to rotate the motor and check 2 and 3 seperately
