SV Carb Question
 
Just bought a set of carbs from eBay. Stripped them down and found that they had been set up with 132 jets.

I had my old bike on the dyno and on a very hot day found that the best fueling was with 134s (that was before adding air filters, race systems, etc.) and I certainly wouldn't recommend anyone goes below the stock jets of 137.5 but...

The only thing I can think of is that the 132 jets have been drilled out as I have seen this before. Anyone ever heard of a bike being setup with stock 132 jets?

The other possibility is that the owner had fitted an aftermarket system that was so restrictive that jets had to go down. Or had nicely blocked air filter.

I removed the restriction, (legally), on a Yamaha a while back, which, along with an inlet restrictor, had been fitted with strangely small jets. I haven't heard of an SV being so fitted when restricted, but I suppose it's a possibility.

Different jet manufacturers' jets with the same number on them have different flow characteristics, the number in isolation isn't that useful. Not a real answer, but a caveat.
