Hello,
I am a first time poster but a long time savage owner.  The bike is a 03 savage with 2000 miles and has the same basic upgrades, slip on Jardine pipe and dynajet kit.  Bike runs very will, but if it sits up a week or so the bowl will dry up, and have to do alot of cranking to get it to fire. Sometimes I do get a faint whiff of gasoline.   As long as you start it daily or so it will start up just fine.  There is no signs of fuel leaking, no puddles, discoloration on the carb. etc.  Any help you guys or girls have will be much appreciated.
Thanks,
David

If you have a dry bowl, I doubt that your needle is leaking.

First, confirm you have a dry bowl.  place a cup under the carb and open the drain.  Nothing?  OK, it's dry.  Flipping the petc0ck to prime will solve the starting problem.  Remember to return it to run after.

Maybe you got a micro leak?  small enough to leak and evaporate without dripping.  I think you can get something to color the gas to leave a tell tale trace of where it's leaking.
