Does it matter which one is fitted to the forward cylinder head, and which one to the rear cylinder head? Yes, it does! ........looking at Square's overhead photo .... https://www.squaremotorcycleparts.co.uk/products/carb-to-head-inlet-rubbers-yamaha-xv535-xv-535-1987-2001 I see the vacuum tube is angled in two different directions. for A and B. In my opinion which goes where should give itself up when it comes to fitting those vacuum tubes, as you want the angle of least resistance and prevent kinking. Having said that your vacuum tubes which probably are 'set' at the position, should enable you to pick the right one. When i say set, they have been in the correct position for many years so they will have a natural set position just waiting to be connected to the correct inlet tube. and this photo has an Arrow for FORWARD so the two inlet rubbers are shown at slightly different angles, you just have to look at yours to match the picture, you've got a 50:50 chance of getting it right anyway!! https://www.bike-parts-yam.com/yamaha-motorcycle/535-MOTO/1991/VIRAGO/XV535-20KW-/INTAKE/70_6973-6973/B8/0/14359
