Greetings,

I need to replace the intake manifold on my 2007 Fly 150. Any tips or suggestions before I start?

I finally got the bike up and running and then the manifold just plain failed. High revs, and low power. I hope this does the trick.

Thanks all!

Pretty straightforward job. Only thing I remember is to clean the area so nothing falls in when you're swapping old with new. Inspect the vacuum hoses that plug into the Y in the new manifold and replace if they're brittle/cracking.

There's a gasket under there... make sure you order a new one and replace while you're in there.

Just curious, what happened that it failed? Cracked/split? Or the brass connector pulled out?

Thank you! Got the gasket. Should I add form-a-gasket when I install?

The boot had a tear. Bike had been sitting for five years when I bought it. I've systematically replaced nearly every rubber part. I finally got it running, and I may have clamped the manifold down too hard and cut/weakened it. It gave out on a short ride this weekend. I think it was a combination of my error and old rubber!

No goop on the gasket. Knock it on dry. A little lube for the carb to manifold allowing it to slide together easier.

Hook it all up and you should be good to go.
