i have just got a set of 4 pods and 2 have holes in the top ? as any got any idea what your supposed to do with these holes and what jets and needles i need any help will be very much appriciatedunk:
Casey, what are the restrictors? Do the go over the carb?
Any pics of them installed?
They go into the air vents tube holes on top of the carbs. Sean is the man to contact for all these type of needs. I've dynoed mid 120's with the air box and stock needles. With some adjustments of course. Putting a stage 7 kit in can kill your low end and mid range without a lot of careful trial and error tuning. Do read Mark Milnes threads on stage 7 set up.
The holes on top of the filters are for the crankcase breather system that comes with Sean's kit or the stage 7 setup. Any Gen 1 Vmax can take advantage of this.
If your pulling the factory airbox and running pods instead I do believe you would need the restrictors also. Morley has those and they are pretty cheap. I had to use them when I went to a custom filter lid.
On needles and jets you might also reflect on Morley and others for a jumping off point. The PO of my bike had the Kerker and the Dynajet stage 1 kit installed, the local shop set it up the jetting per Dynajet instructions. It was so rich it was stumbling and stunk of faw fuel, started hard and got dismal MPG. I had to drop several jet sizes to get it good and proper like she should be, I'm at 4000'. Even with the free flowing filter led and full Kerker exhaust I'm a couple steps leaner than factory jetting.
Yep, I agree with you 1000%! The exhaust would change the entire original breathing design of the engine.
Stock exhaust will work best with the stock intake system designed to take advantage of the resonant airbox design. But change the exhaust and the stock design would need to change, and hence the stock airbox may now become a restriction and the resonant design may not work the same anymore.
Great link here and a better explanation than I could ever think of about airbox resonance. Whenever someone comments to me about the intake of some bike looking too small in the airbox, I'll have to show them this video. I think a lot of people assume that the bike breathes all at once and constantly and they say; 4 big carbs breathing through such a small intake area in the box. But they don't realize that they engine is not breathing in all at once. And all 4 carbs are not breathing all at once. These resonant pulses are where the airbox design comes in;
