Torquing the exaust pipe nuts to the engine

[mklln2090]

I am having to install a right side exaust pipe. The service manual is many times misleading and incomplete. My torque wrench is in Inch/Pounds. How can I convert from 10N.m (1.0 kfg.m, 7 lbf.ftg) in the service manual to what I need or am I going to have to buy another torque wrench which I don't want to do. Thanks.

Personally, I wouldn't use a torque wrench on those. Many have done so, and many have snapped a stud. Take them up to a good, snug point and leave it. Go back in 100 miles or so and snug them up again. If you used new gaskets, you may have to do it a couple times.

   Are you using new exhaust gaskets? I just changed my 50,000 mile original exhaust for 2 Bros 6x6 and even though I had new gaskets I thought I'd try leaving the old gaskets in place and see what happens. I installed the new pipes, snugged the nuts, cranked her up and all was fine no leaks, no ticking. I'm not sure that the snugging would have worked with new gaskets. After a couple of rides I rechecked them, still good and snug!

I use a 1/4" drive ratchet and hold it close to the head of the ratchet to reduce the chance of breaking a stud.  I had some problems with my header nuts loosening when I first got the bike. Tried a torque wrench and they still loosened back up. Then I tried using the 1/4" ratchet instead and they still loosened up after a while. Then I tried tightening them up by feel with the 1/4" ratchet while the pipes where hot. They haven't loosened in years now, not since I tightened them while hot.

Hey, welcome to the VRCC mklln2090,

I would agree with those who say tighten the nuts until snug and forget the torque wrench.  Repeat as necessary.  Unless you are really young or really inexperienced, you probably already have a good feel for tightening nuts/bolts without stripping them.  (If you are really young or really inexperienced, then as my father always told me, "you'll never learn any younger.")  Trust your instincts (seems like there is a Star Wars image in my mind here).

Good luck.

And again, welcome to the VRCC.

Unless you have some interesting tools, torquing can be a problem. I couldn't get a socket onto a few of the bolts and had to use a tiny little wrench. Snugged them up with new crush washers (not really sure I got all the old ones out), rode for a week and snugged them again.
No noise or leaks in over a year now.

The best tool I have found yet is a combination open end/box with a ratcheting box (make sure its reversable) it gets to all the nuts with ease.  I second the FORGET THE TORQUE WRENCH thing.  Just choke up on the wrench so you dont have a lot of leverage and go till they are snug and a bit more for good measure..........its really hard to overtighten them that way unless you try to.

Oh, and check the hanger bolts occasionally. One of mine came off and I had to get a replacement from the hardware store. Snug them up every time you snug up the header nuts.

I used both a ratchet and little wrench and only used my pinky to tighten them with. Go back and recheck after a few days. If you break one they are a royal B to get out.

Not very technican.
But after snugging mine up twice after changing pipes.
I just added a cap nut.
Nothing loosened up in 1500 miles.
