Venture Mod for the Maxim-X?

When I owned my Venture, I did this mod to my intake manifolds with excellent results as pointed out by the inventor of the mod now caled the Jason Mod. I have included the link to the Venturer's website to the mod page itself for those wanting more info or pictures. Since my Maxim-X has a similar design except an inline 4 vice the v4, I'm wondering if the principle would be the same and therefore, the results would be the same. I'm hoping the XJ gurus will comment and give their valued opinions. Here is a brief outline of what the mod theory is and how to do it.

The Jason Mod
The theory behind this modification is simple. ALL engine tuners know that if you design an exhaust system with the cylinders that are timed 180 degrees from each other to dump into a common collector, there is sizeable increase in efficiency a.k.a. more horsepower. Well the same goes for a correctly tuned intake system. Just look at the V-MAX and you'll know what Yamaha did to increase it's potential. Simply put , this modification is a simple V-boost that works all the time.
HERE'S WHAT YOU DO

1st GEN.1200 - Disconnect the YICS hoses. Then using 1/4" fuel hose connect the two left cylinders together at the YICS spigots(1 & 2). Then do the same for the right side (3& 4).
1st GEN.1300 - Since you do not have YICS, the connections are made at the carb. sync pipes that stick out of the manifolds.You'll need 3/16" fuel hose and a 3/16" vacuum tee. The vacuum tee is because there is a vacuum line connected to manifold #2(left front), which goes to the ignitor box. Remove the rubber caps from the other 3 pipes. NOW using 2 1.5" pieces of hose connect the tee between #1 and #2 manifolds and attach to their pipes. Then connect the hose going to the ignitor so the hose basically goes up(yes the tee is upside down).NOW using a 3.5" hose connect the right two (#3 and #4) cylinders together.>>You're done...
2nd GEN. 1300 - The only difference between the 1st gen. and 2nd gen is the location of the vacuum hose to the ignitor. I think it is at the right rear manifold #3. So the location of the tee would be opposite.
RESULTS

Quicker throttle response at all rpms, especially down low.
More pull at small throttle openings allowing higher gear usage around town.
You'll be able to redline the bike at less than 1/2 throttle in the gears 1st, 2nd & 3rd.
Better gas mileage , usually 5 to 10%
The only negative, a slightly lumpy idle.
I HAVE HAD THIS MODIFICATION ON MY BIKE FOR 50k miles without a problem. Never fouled a plug. In fact my plugs were last changed with 25k miles on them, and they still were good! If your Venture ran good before, then it'll run great now!

Connecting the vaccum ports to "balance" the intakes has been discussed several times - most often called "the poor man's YICS".

Basically - it does nothing.

Some report noticing a difference, most don't notice a damn thing. Doesn't hurt anything though, so if you want to try it, go for it.
