Suzuki Quadrunner 250 Adjustments

[GTX-Racer]

I recently purchased a Suzuki Quadrunner 250.  I am not sure of the year.  I plan on  rebuilding the carburetor and looking to do some maintenance before using it.

 

I also purchased a Quadrunner 160 and planned on doing the same maintenance.  I have the same question for the 250:

I am going to change the oil, which is simple enough, but after reading the manual there are many adjustments that are needed when the oil is drained.  Does anyone have any advice on the valve clearance or clutch adjustments?  Both require the oil to be drained and the engine at top-dead-center.  Anything else that I should do while it is in this configuration?

 

I am unable to find a manual online for the 250.  Does anyone know the valve clearance setpoint?

Not sure why the oil needs to be drained, but a good time to do it, intake .004 exhaust .006. Some had tighter clearances intake .002 exhaust .004 not sure which model or year yours is.

The manual that I have for a Suzuki 160 has you remove the side cover after draining the oil to verify top-dead-center position.
