but the options are: Enhanced mode on at 3K Enhanced mode off, normal at 6K and No VBOOST, I guess you just run with the boost valves open all the time.

Has anyone done this mod and is it worth it??? :confused2...

Just wondering if any other VMAX Forum riders are in Hawaii???

Did you at least buy her dinner before you plugged up both holes like that???

Throttle cables are good. All clamps are tight. The manifold is tight with a new o ring. Choke plunger is completely closed. Carb is even with the boot. No cracks are visible. I covered up the top of the carb and it cuts off with no rise in the meter. Could there be anything wrong with the carb...

Tried the water....no change. I have a compression tester, but I don't have the right fitting for the plug size. Just wondering, can an exhaust leak or a valve cover leak cause a loss of vacuum? Do I have to open my vboost butterfly's during sync at all? I'm keeping them fully closed right now...

Well, I took off the carbs and replaced the choke plunger. Still no help. Any suggestions on what to look at?

I found out why I'm loosing vacuum and where that straw sucking noise is coming from. The #2 carb's butterfly is not closing all the way. It's not the throttle cable either. It's like this on the bench. I have the thumb screw all the way out and it still has a constant gap. Is this normal? If...

Tried the thumb screw, no help. When it is running, I hear a noise similar to someone puffing or sucking air through a straw coming from the #2 carb. Is this normal? This is my first VMAX and when I bought it, it was running really rough so I rebuilt the carbs. What could be wrong with the #2...

I'm trying to sync my carbs and I'm having problems with the #2 carb. I am using a Carbtune 2 and I can't get enough vaccum to move the #2 rod up at all. I swapped the #1 and #2 tubes and the guage works fine. I messed around with the pilot screw as well as the #1/#2 sync adj screw. When I blip...

That worked......thanks.

Ok. I set my dry float levels according to the casting stamp on the jet block like in the dry float level thread. Right now, my #3 carb is overflowing fuel through the overflow tube. What should I look at?

AMSOIL 20W-50 for hot weather areas and 10W-40 for cooler weather areas with an AMSOIL filter. I use it in everything. I have it in my SUV. After a year, I bought an AMSOIL sample kit and sent it in. They analyzed the oil and told me everything about it. Weather it's breaking down or if...

Rebuilt both slave and master and it works like a champ. :eusa_dance::eusa_dance:

Thanks for the info. So did you pump and hold the clutch in when you opened the banjo bolt or do you just open it before you pump the clutch? I would think if you pump it, it would force the air bubble downward and only pressure from the master would come out instead of the bubble traveling back...

I just tore apart both the master and the slave. The master looked pretty good, but the slave had a TON of **** in there. I cleaned it out and now I'm just waiting for the rebuild kits. Trust me, I had the master cylinder assembled right and I have bled many of hydraulic systems in my time. I...

Thanks for the ebay link. I'll buy it. It's just the right way to go.

I was looking at the carbtune pro that uses metal rods. Would that be sufficient or do I have to get the weber syncs? Also, which two are the vboost intakes? 1,2,3,or4?

I just bought my 97' VMAX, and the vboost was removed. I just rebuilt the carbs and now I am having trouble synchronizing the carbs. Is there any special way to sync the carbs with the vboost removed? If it is easier to sync with vboost, what are the minimum vboost components I need to install...

Well, after gravity feeding the system, I still have problems. I'm just going to take it apart, flush, inspect, and rebuild both the master and slave. Found kits on ebay for under $50 for both. I just got this 97' beast and probably need to go through it anyway.
