Exhaust removal and replacement
I got my deCATed head pipe today in the mail so I am in the process of removing the stock head pipe.
I have a few questions:
I have a few questions:
- When removing and replacing the O2 sensors, do I need to put anything on the threads or just screw them in dry into the new pipe?
- What is the torque spec for the cylinder head flange nuts?
- What are the torque spec for the clamps (yep I know they are supposed to be replaced but these have like 1100 miles on the bike).

2. 80-120 INCH pounds. run for a while, then re torque while hot
3. I think this is 40 Foot pounds. Reusing is not a function of time on the bike, rather the exhaust clamps get bunged up when you torque them. I was able to reuse one of mine but not the other.
The service manual is your friend. Get one.

tighten bottom nut of rear cyl ex flange to 9-18 in-lbs, tighten top nut to 100-120 in lbs, final tighten bottom nut to 100-120 in lbs.
then do the same for front cyl. I always re-check after running bike
Buy yourself a HD manual, if you're going to work on your bike! Also, buy new gaskets.
Good Luck.

Thanks all for the responses!
I definitely need to get a manual - I have electronic versions for all my other bikes, just can't find one for the later touring models! I guess I will have to break down and buy one.
I have new gaskets - including the pesky cross over!
All of this is a mute point for the short term - I went to install the gutted headpipe that I bought on eBay and found a dent in the front pipe with no visible damage to the shipping box.
The seller is going to do the right thing and is sending another but now I have to wait on shipping!
I guess I will be stealing the wife's bike for the weekend!
