Intake manifold gaskets
I am going to have my intake manifold gaskets replaced this Spring, on my '05 Sportster, and I am wondering what is a good brand? Thank you!

Cometic is the way to go on almost all the gaskets. James' push rod tube base gaskets are the one exception. I suspect a leak at the heads is more common than the carb side. I just pulled my manifold and where the bolt goes through the bracket I could see getting a leak if you're not careful as the bolt eats into the rubber right there.

I went with the HD seals just to be safe. There's a dealer about half hour away, so it wasn't a big deal to get them.
I'm sure the Cometic seals would be fine, too. I think the FSM says to use dish soap, but I used red grease without issue.

I had the bike worked on awhile back, and after ~6 mos. the problem reared its ugly head again. Happens after the engine is fully warmed up; when I crack the throttle, it falls on its face and pops back through the carb. After viewing some instructions online, I realize proper installation/assembly technique is important Thanks for the info.
