Charlene and I, Wingman aka Jamie, Paula, several cousins and their spouses will be departing form NOLA on a 7 day Caribbean cruise.:banana: This is our second cruise and looking forward to it. We are doing it differently this time, only booking one excursion, the rest we will do freestyle on our own. Four ports, Cozumel, Costa Maya, Belize, and Roatan. If you have any suggestions on what to do or see while we are freestyling, please feel free to let us know. Last cruise was on Carvinal, this one is on the Norwegian Star. :dancefool: Have heard lots of good things about Norwegian.

I made one of these and it works perfectly. I used old motor oil for the liquid. Sync #1 to #2, then plug those and sync #3 to #4. Then hook up tool to #2 and #4 to sync left side to right side (make sure to plug ports on #1 and #3).

Linking the Vacuum Ports Taken from various posts on the VentureNet Forum http://www.venturers.org/NextGenTech/2ndGen/images/ais_tee.jpg This is a simple and near zero cost modification that improves low end throttle response and is claimed to increase gas mileage. (yet to be verified) The only drawback is that it causes a slightly irregular idle. Step 1 - Remove the rubber plugs from the vacuum ports of cylinders 2 and 4 and the AIS hoses from cylinders 1 and 3. Step 2 - If you have already disabled the AIS by plugging the hoses going to the exhaust ports, then the small rubber hoses attached to the vacuum ports of cylinders 1 and 3 can be left disconnected. For protection, they should be plugged. (a spent .22 shell fits very nicely) Step 3 - If you plugged the hoses in step 2, then connect a piece of 3/16" fuel line between the vacuum ports of cylinders 1 and 2. Connect another piece of line between cylinders 3 and 4. Skip to step 5. Step 4 - To leave the AIS vacuum control enabled, connect the control hose to a small T fitting with the other 2 ports of the fitting to the vacuum ports of cylinders 1 and 2. Repeat for the other side. (A suitably sized brass T is available from aquarium supply stores.) Step 5 - Ride your bike and enjoy the increased performance and mileage!

externally, there are 4 inlet ports, and 2 exhaust ports. internally, there are also 4 "tubes" on the inlet ports and 2 tubes on the exhaust ports.my question is ,would removing or shortening the "internal tubes" , have any serious effect on the overall engine performance? referring mostly to carbs. just jt -
I've been meaning to remove the YICS chamber on my 83 before it becomes a problem. I bought some caps to plug the ports with, but got reined-in very quickly when I tried to get a good look at the inner YICS cylinder ports : the outer hoses are no issue, but I can't even see the inner ones. So my question is this : is it possible to remove the YICS hoses & cap off the ports without having to pull the whole carb rack ? It looks way too tight in there for my hands. I do have a 4-yr old, but she isn't all that handy with a pair of pliers (yet). Just wondering... -
My exhaust on the '87 VR is starting to get loud. It's hard to describes because it's not just a loud muffler type noise....it sort of comes and goes throughout the acceleration. Is quiter when cruising and off the accelerator. Seems to get a little quieter after it has warmed up, but not as quiet as it should. I have visually inspected the system and can't see any obvious rust through holes or anything that would appear to be the problem. As a result, I can't pinpoint it with my ear either. I am hoping the issue is gaskets between the exhaust and the cylinder head. To get to the front cylinder heads where the exhaust ports are, do I need to remove the rad? It looks that way. How do I get to the rear cylinder exhaust ports?

I saw a modification on another site which claims that linking the intake ports by joining the same vacuum ports which we use for sincronizing the carbs gives somewhat better low end torque, albeit at a slight sacrifice of idle smoothness....Has anyone here ever done such a thing?????????

As part of trying to get rid of the off idle skip on my 83, I removed the hoses and plugged the ports on the YICS system. The bike runs so much smoother and I can not tell any significant difference in power, so what did the YICS system actually do? I noticed on the 86 engine that the ports are not even machined for a tube for the hose. RandyA
