Hello Tew,
Kawasaki uses several tightening torques for all sorts of bolts and nuts, you did not specify which was the problem. But I looked into the Kawasaki EX250R service manual and found a table with relating tightening torque to thread diameter. This lists the basic torque for the bolts and nuts. You cannot use this table for engine parts, if it is a engine part which is not tight enough you have to specify which bolt or nut it is, and I give the correct torque.
It is maybe also a good idea that you call Kawasaki, as one of your first service checks is as I belief after 800 kilometers, Khon Kaen is about 400 to 500 kilometers from Bangkok....
I'm Tew, I got my Kawasaki EX250R Ninja 250R a few days ago, I live near Khon Kean and I found that some bolts on my motocyc where a bit lose.
My local mechanic has no idea what the tightening torque is for the Kawasaki Ninja 250R I not want to ride back to Bangkok.
Does somebody knows how tight the bolts and nuts need to be screwed on?
Sorry for my bad english...
