Okay Brian, we all know you are thorough, but you used a torque wrench on that little plug bolt? Geez, do you torque the seat bolts to spec. after you clean your filter? Speaking of the air filter, how do you get a torque wrench on that wing nut, and what is the spec?

Actually, the cam bolts, valve cover bolts & timing chain tension are all 10Nm - just a matter of changing from an 8mm socket to a 5mm allen head. Haven't figured out how to get a torque wrench on the wing nut - hell, most the time I can barely get that thing started anyhow.

get your torque wrench recalibrated. they can be seriously off. the snap-on man did my fathers FOC every year as a matter of course.

I used to work at a shop that had a Torque wrench calibrater, I took all the wrenches' torque wrenches in and tested them.
They were all over the map.
Up to 25% deviation from the correct readings.
This could turn into a different thread, but the proper care and feeding of a good torque wrench is not widely known...Let alone using one properly...
I ended up replacing all my wrenches with snappy stuff. Clicker types that are always dialed back to zero instantly after use, and a torque-o-meter for more precision engine components.

Tim, you got me laughing. I've cussed my way through all of those "routine" mntc procedures. At least they finally got smart and moved the header pipe, only 3 years too late. Now how about designing side access to the airfilter and a plug where you don't have to remove seat and tank to get to.

I too have damaged the tensioner plug bolt mechanism. The first time I checked my valves I accidently torqued the plug bolt too tight and stripped all bar one thread from the actual tensioner surround. I'm not sure what alloy it is made from, but it is like putty! Now I have the bolt virtually glued in with Loctite and it hasn't come off yet.
I agree with the wing nut issue. Sometimes I might spend 5-10 minutes trying to get the airfilter mounted correctly.

That said allways use torque wrench for the important! stuff eg head bolts
