torque specs for FP mani?

[SuperjetSteve]

Anyone know what torque numbers i need to torque my mani bolts down?for my type 4 pipe?

 

[Shonuff]

20, then 38 ft*lbs

just a word of caution. I wasn't using a torque wrench on mine and my manifold came loose in daytona keeping me from riding for a day. Really sucked, being down there and not riding. make sure they are tight if not using a Torque Wrench

I stripped all 3 holes in my manifold at 38 lbs. It was quite annoying as the pipe was brand new, never installed.

 

[Shonuff]

What the hell?

 

[yankeeboy]

We gradually built up to 38 lbs, going up by small incriments. I think it has the torque specs on FP web site?

 

[Fro Diesel]

that's crazy. must be an isolated incident. I seriously tightened mine down crazy tight and maybe i will be sorry but i know i am over 38ft/lbs...i really leaned into putting them back on.

Factory Pipe's instructions:

20/38 is OEM, FP says 18/28. It's the same holes so I don't get it.

manifold to cylinder?

or headpipe to manifold?

 

[ChrisGooch]

I'm a bit slow today... I meant headpipe to mani
disregard my above post lol

I don't go over 30 ft lbs on the head to manifold.

Sweet guys thanks, now i gotta get my hands on two stock Bolts!!

 

[douglee25]

Have fun finding them! There are an odd size for sure. I ended up buying SS bolts with a long shank and threading them on a lathe.

One of my headpipe-to-manifold bolts on my B-pipe was a wrong thread (fine vs. coarse thread) and I went to my local ACE hardware and picked up the proper bolt - in fact it looks like it was made at the exact same factory. :biggthumpup:

 

[SuperjetSteve]

So i guess ill torque then down 18/28 like fp says?

do the 28 for sure. 38 is way too tight for that small of a bolt that is going into aluminum. IMO. I will be checking mine frequently.

im just using three of the cylinder base bolts on my b pipe headpipe to manifold connection.....since i am running a gridled head i dont need the cylinder bolts.

Also i heard fp's bolts rust so id rather stick with the factory bolts since i only ride salt
