2003 Savage. 6,500ft. elevation. HD Dyna exhaust, K&N cone filter, 52.5 pilot jet, 147.5 main jet. Trying to eliminate backfiring.
The #52.5 pilot jet is definitely too large for your altitude. Drop to a #50 and see how that works for you. If it is still too large then drop down to a #47.5
I changed the 145 main jet to the 147.5, installed, tuned idle screw. Still got the backfire.
The pilot screw and the main jet have virtually nothing to do with each other.
The main jet has virtually nothing to do with the backfiring issue as well, it is associated with the pilot system.

I bought the 150 main jet, installed, tuned idle screw. Now it dies when I give it throttle. Help please....
For your altitude I suspect that a #147.5 would be what you need.
When installing the 150 main jet, it never seems to fully tighten in, just keeps spinning. I also noticed that the jet can be pushed up into the carb, then it pushes itself back down, is it suppose to do this?
Were you able to verify whether you have a brass washer under the main jet or not ? It is REQUIRED, so if not then you need to get one, otherwise the carb will never work as advertised.
Thanks for any advise!!!

Are you clear on the adjusting and tuning procedures for the pilot, needle and main jet systems ?
If not, then go to the "Tech Section" and review the several good write-ups on the subject.

However, now it spaces too far and the main jet threads won't catch. Thanks for all of the jetting info, I will reduce to my elevation. I want to get it back together for now though.

Then you need to rotate the brass needle jet until it drops down into the carb body. There is a notch that needs to line up with a pin....and evidently you don't have yours lined up.

Reply #19 - 07/28/16 at 15:10:23 Compare the threads of the original jet to the new jet. Try threading the original jet back in, Using the washer. You will have an answer. How hard did you twist on the new jet screwing it in? Did it ever Feel hard to turn?

I took the top of the carb off, and seated the main jet sleeve. Main jet (147.5) and washer went on perfectly! Put it all back together, she started up first try. Ran it down the road a bit, when I gave it 1/2 - 3/4 throttle she started sputtering. Took back to the garage, now she won't turn over. Took the carb bowl, the main jet is still intact. WTF!?!?!?

I had to open the because the sleeve wouldn't sit down into the chamber fully. It needed a slight tap from above.

Reply #28 - 07/29/16 at 11:56:43 You might want to try charging your battery. The voltage can drop low enough that the ignition doesn't provide spark - but the battery is still able to run the starter. This can occur when people take very short trips and the battery doesn't get enough of a charge to replenish the power used running the starter motor.

Reply #29 - 07/29/16 at 12:05:12 What sleeve ,do you mean the slide with the rubber diaphgram? If you do the slide needs to be clean ,(not even touched be your fingers) if dirty it could be hanging up .this would explain your bike not running for sh*t.
