You are dealing with Suzuki vacuum carbs, you cannot just replace the air box and re-jet. What you are running into is there is no pressure to raise the diaphragm because there is no restriction to create such vacuum. Either put the stock box back on or go to the biggest main jets you can buy. Sometime even when you get stage 3 jets you still have issues. Vacuum carbs are not made to run with no restrictions.....putting aftermarket exhaust on it will make things much worse.

Savage 2008, the traction stops suddenly climbing on a cold weather


Hi, Anonymous the answer to this question is way above my pay grade for this situation, but I'm guessing you may need some carb jetting with all that up in the clouds stuff assuming you have no intake leaks you can try running without an air filter as a test if that helps move the c-clip on your needle jet up a notch or two and/or drop down one size on your main jet and put the air filter back on and for confirmation I would call or visit my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry.

Ls650, S40, BS40 Mikuni carburetor, I want to fit a pod filter, but bike runs all funny ,even if i take side cover off the airbox?


If you fit a pod filter, or take the lid off the air box, you are allowing more air into the engine. Therefore, you must also allow more fuel to mix with the air. To do this, you must increase the jet size in the carburator. I recommend Dyno Jet brand jet kits. They will have all the parts necessary as well as tuning guidelines to follow.

What is the factory settings on the car jets


Dont know what you are trying to set. Only thing about the jets you can set outside of changing the jet size is the little clip on the main jet needle top. Normally the middle groove.
You can pop the factory plugs on the primary jets (idle jets) and mess with them a little to richen or lean it out a bit but they are preset at the factory. Normally a bit lean.
