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

SOURCE: is there a coating on cylinder of my 01 kx 250

Yes, that is a plated cylinder so if it galls, or wears out, it cannot be bored out you have to put a new sleeve in it. The new sleeve will be able to be bored out so it will last for a long time. The resleeving is best left to a cycle shop or machine shop with the propper equipment, as it is an interfearence fit and the cylinder must be bored perfectly, then heated in an oven to be able to install the new sleeve.

Cylinder bolts @ 25 ft/lbs (34Nm)
Cylinder head nuts @ 18ft/lbs (25Nm)
Check these nuts again after first warm up and again after first two rides to let gaskets bed in and seal. Cheers.
