It was impossible to find original jets for my carburettor here in Guanajuato. But carb rebuild kits for smaller displacement motorcycles are plentiful. So I purchased two different, cheap kits. The pilot jet from one of them fit and the main jet from the other kit fit. But they were meant for 125ish cc motorcycles, so the perforations were a bit small. So what's a fellow to do? I took a safety pin and ground it down to a flat, screwdriver like tip. And used it to manually grind the pilot jet opening a little bigger. It did put my patience to the test, but after 20 minutes or so I was done. Using the same rationale, I found that a 3/64 drill bitt fell through my original main jet. So I used one of those to drill open the generic main jet that came in the second kit, leaving it a little tighter than original. And tada, now she runs even stronger than before.
I am pretty much the only one I've heard of who has gone down in jet sizes for the Savage. More so since my exhaust is open (except for the perpendicular washer) and I have a free flow air filter. I guess it's because of Guanajuato's high altitude.
So drill 'em open. I'd recommend saving the original jets with their original perforations though, just in case.
Not for Pussies!
