Do ya'll replace intake manifold orings each time?

Postby jtimgrant » Wed Nov 20, 2013 11:10 pm



I'm suspect my orings are leaking when engine gets hot. The manifolds have been removed numerous times without changing the orings. Should they be changed each time the pipes are removed?

Also, anyone know a local source for the o-rings?

If they are getting hard and brittle or have been smashed. By all means replace them. You can get them from your Honda dealer or run the part number on e-bay.
If you think the intake is leaking spray a little carb cleaner around the fitting and see it you get a change in engine speed. Or if you have a propane tourch, turn it on and move it around the intake and see if you get a change..... (UNLITE OF COURSE) :oops: :o
Enjoy the ride. They are all good, just some better than others.

O-rings were leaking but only noticeable when hot after running awhile. Plugs burning very white. Idle would increase from 1000 rpms to 1200 rpms after about 30 minutes riding. Carb sync would also change. Removed the vitron o-rings. Smashed flat. Replaced the orings, re-sync'd the carbs, took a test ride. No idle change. Also had to reset the pilots. Running rich with new o-rings. Haven't checked the plugs yet. Too cold or blood too thin.

Sounds excellent. I like to use OEM O-rings and gaskets when possible. Glad it worked out. Nothing like fixing a problem and having it work right.
