SOURCE: 91 kx 250 torque values
Engine Top End:
Auto Decompressor Bolt 104 in·lb
Cylinder Head Cover Bolts 87 in·lb
Cylinder Head Bolts: M10 36 S
M6 104 in·lb S
the S in that means the specified pattern ... just like tightening car tire bolts... please note all that it its INCH lbs....
don't know why it says just 36 for the M10 bolts unless they left out inch lbs
Anything else let me know as i've got a manual for the 250 f... actually i've got a few different ones
Please take a moment to rate this solution as i've taken a few minutes to find the manual thanks

The haynes book is not recommended since there are numerous mistakes and they still will not update. One of the biggest is the firing order.
The factory service manual is the only way to go.
Head bolts - 46 - 50.5 lbs (there is an order sequence for the bolts)
Intake & exhuast manifolds- 13.5 - 20 lbs
Flywheel - 41.5 - 47 lbs
Clutch cover - 13.5 - 20 lbs

The engine needs air, so be sure the air filter is clean. If it is not, replace it.
The engine needs spark. Replace the spark plug and be sure that the battery has a complete charge.
The engine needs good fuel so be sure the gas is newly purchased, not gas that has been sitting around for months.

Always use new head bolts.
1)tighten to 40ft/lbs
2)back off 1/2 turn
3)tighten back to 40ft/lbs
4)tighten an additional 90 degrees
5)tighten an additional 90 degrees.
