intake leak on 05 FLHRSI
I have an intake leak on my FLHRSI.
I've been riding it like that for the last 3 years.
The idle seems questionable, it doesn't seem to settle down to an even idle.
The bike is a 95" with se heads and an Andrews 54 cam.
Trying to ride the bike at 10 mph is a pain, it stumbles and misses a bit.
I just never knew how it should run or if I was being too picky ( I do that a lot).
Anyway.... I shot the flanges with some brake clean this morning and there is definitely a leak at the rear head and probably one at the front as well.
My question, are there intake gaskets that are better than others?
Who sells gaskets that are superior to the HD ones?
I'm not saying that stock gaskets are crap, I just want the best shot at doing this one time and it lasting.
BTW, the SE heads were installed when the bike was brand new, so its probably always run like this.

Nothing wrong with the HD SS mesh (PN 17048-98) gaskets; some have had to double up on them to solve a leak problem; they are a tight fit and will not crush into the exhaust port. Cometic and James both offer similar products but I have used the SE SS gaskets many times with no issues. Do not use the crushable cone shaped gaskets. When you replace the gaskets, make sure the head pipes are properly aligned in the port. Hang the exhaust but do not tighten anything; just snug but allowing the head pipe to move. Pull the head pipe inot the port slowly and evenly; you will feel when it comes in contact with the gasket. Then start tightening evenly and do not over torque; IIRC, 135 in.lb. is the specified torque. Finish tightening the hangar support, fire the motor up, check for leaks. Go for a ride, get the motor up to operating temp, return and let the motor cool before re-checking fasteners.
Never used any aftermarkets , but never had an issue with HD seals. Not sure about 05, I know earlier model require a special or modified Allen for the bolts because of clearance issues.

Sounds like a the intake seals were not installed properly. A bit of a PITA because you will have to remove the intake manifold to replace them but if you do it properly, should solve the problem. OEM intake seals are as good as any; all pretty much the same. It won't make any difference which seals are used; if installed properly, they will seal the intake. Good luck.

My bad; can't explain how I read intake and responded to exhaust!

You were right on the money. The rear seal looks like somebody pushed it into place with a small slot screwdriver, there are 3 cuts in the inside face exactly were the brake clean showed a leak.

Replacing the seals is a pretty basic operation but there is a right way to do it to insure a leak tight install.
