Did some remodeling/updating this summer. Can't find my f'n manual!! Reinstalling the stock exhaust....what is the proper tightening sequence/torque values. I have the exhaust on the bike now and all bolts are loosely fastened. I figure there is a sequence to tightening everything down.

TIA!

Tighten the exhaust system as follows:
a. Tighten the top nut of the front cylinder head exhaust
flange to 9-18 in-lbs (1-2 Nm). Tighten the bottom
nut to 100-120 in-lbs (11.3-13.6 Nm). Final tighten
the top nut to 100-120 in-lbs (11.3-13.6 Nm).
b. Tighten the bottom nut of the rear cylinder head
exhaust flange to 9-18 in-lbs (1-2 Nm). Tighten the
top nut to 100-120 in-lbs (11.3-13.6 Nm). Final tighten
the bottom nut to 100-120 in-lbs (11.3-13.6 Nm)

 

Thanks PistonPuller!

I'm guessing that after that I would tighten down the bolts to the frame in the rear last. Do you have a torque for those or just good and tight? I have them in now holding up the exhaust but they are just finger loose.

 

This is from my 09 Touring manual. Maybe it will help with whatever bike your working on


1. If removed, install transmission exhaust bracket (12) and
tighten fasteners (9) to 84-132 in-lbs (9.5-14.9 Nm).
2. Install new gaskets in both the front and rear cylinder head
exhaust ports with the tapered side out.
3. Place exhaust header pipe into position on motorcycle
and start two exhaust flange nuts to secure front header
pipe to studs of front cylinder head.
4. See Figure 4-41. Roll pipe into position at rear cylinder,
making sure welded bracket on header pipe is below the
side exhaust bracket (18).
5. Start two exhaust flange nuts to secure rear header pipe
to studs of rear cylinder head.
6. Secure header pipe to side exhaust bracket (18) with
carriage bolt (16) and flange nut (21). Do not tighten at
this time.
7. Slide new clamp (4) onto crossover pipe.
8. Install new gasket (5). Twist and push crossover pipe (8)
onto exhaust header pipe.
9. Install exhaust support clamp (7) and secure with fastener
(6). Do not tighten.
10. Install mufflers
NOTE
Verify that the exhaust pipes do not contact the motorcycle
frame or any mounted components.
11. Tighten the exhaust system as follows:
a. Tighten the top nut of the front cylinder head exhaust
flange to 9-18 in-lbs (1-2 Nm). Tighten the bottom
nut to 100-120 in-lbs (11.3-13.6 Nm). Final tighten
the top nut to 100-120 in-lbs (11.3-13.6 Nm).
b. Tighten the bottom nut of the rear cylinder head
exhaust flange to 9-18 in-lbs (1-2 Nm). Tighten the
top nut to 100-120 in-lbs (11.3-13.6 Nm). Final tighten
the bottom nut to 100-120 in-lbs (11.3-13.6 Nm).
c. Tighten flange locknut (21) to 20-25 ft-lbs (27.1-33.9
Nm).
d. Tighten crossover pipe clamp (4) to 25-30 ft-lbs (33.9-
40.7 Nm).
e. Tighten fastener (6) to 14-18 ft-lbs (19.0-24.4 Nm).
12. Install heat shields. Position each worm drive clamp so
that screw is on the outboard side in the most accessible
position and tighten to 20-40 in-lbs (2.3-4.5 Nm).
13. Connect O2 sensor connectors and install new cable
straps to secure front connector to back of cross brace.

 

Thanks again. Bike is a 2001 Night Train so it's a bit different. But that helps. Found another post somewhere where the tightening sequence on the header nuts is just the opposite. Don't know if that would make any difference or not but would like to confirm. Torn the house UP looking for TFM. No luck! Hate when this happens!
