Low RPM, power loss, incomplete fuel burn

[sachimore]

2002 Bird, during idle it misses and you can smell raw fuel coming out of the muffler. Above 1,500 RPM it's fine. 67K. Always garaged.

 

Vacuum lines tight

Almost New plugs

No FI light

Never adjusted valves

 

Any ideas welcome

 

Thanks

Disconnect the power commander if it has one. Replace the fuel pressure regulator.

Check for fuel in the fuel pressure regulator vacuum hose.

Sach, because of the vagaries of autocorrect in our lives, I want to clarify.  NEVER adjusted valves....or NEWER adjusted valves?

[sachimore]

Never have had them adjusted. Had an older guy that was Honda trained and worked at a dealership 20 years. Then opened his own shop and he talked me out of checking the valves. Eventually he moved away.

With 67k I'd suggest checking the valves.  The Honda trained guy is an idiot.  They might be fine, but if they go tight you'll be coming back to ask how much it costs to remove and repair the cylinder head.

We should start a poll to see how many have had the valves checked.

So far it seems that as long as I leave the cover on the bike they seem to stay in spec.

As cited by rockmeupto125 and superhawk996, that FPR merits attention--don't overlook it.

As in not riding it, just in case anyone thought he meant "valve cover".
