1989 carb seat problem

[zoomjay]

Making some progress with this set of carbs although have not found that one of them is barely flowing fuel... am thinking that the little screen attached to the needle seat is clogged. Problem: how do I get the seat out of there - it appears to be jammed in there pretty good. Am I missing an obvious set screw??? I am afraid of pulling too hard and bending the little metal shaft which holds up the float. Help and guidance is appreciated.

The seat actually comes out from the top so you need to push it up NOT pull it down. You will need to remove the plug that is in the carburetor above the seat. I had a friend that was able to push the seat up and force the plug out but this damaged the filter and I have heard of other that drill a hole and use a small self tapping screw inserted into the hole to pull out the plug. The plug is held in by an o-ring is all as is the float needle seat. Once the plug is out just push up from the float bowl on the seat and it should pop out with the filter attached to the top of the seat. You can get replacement filters from Yamaha and I have seen them available from other suppliers, but if you order a new needle seat from Yamaha, it comes with the filter attached to the seat already. Here is a link to a part fiche for the 89 VR carbs. Check out items 34, 35, 36, & 37 for the items mentioned in the post.. http://www.partshark.com/oemparts/a/yam/5107f835f870022108d6576a/carburetor-non-california-model

Hope this helps and good luck

Before you remove it check that the carb bowl vent is open. I had a vent hose plugged and caused problems on an '85 I'm working on.

I had not thought about taking it out that way... now... how to get that darned plug out of there. I am guessing that using a self taping screw will damage it. I have a new seat and filter and am not worries about hurting the one in there now... maybe I do just shove it out of there...

Drill a small hole into the cap. Start a screw into the hole, back it out. Get a socket that is just larger than the cap and a washer that will fit over the socket but small enough to hold the screw head. The length of the screw is important as with the socket and washer in place the screw should just start into the cap as before. Now with the socket and washer in place insert the screw and turn. You'll have made yourself a cap puller.
