When was the last time the valves were adjusted? After 3 years I would look at that.

Here I guess is a good place to start, everyone here who had to replace then at one point and hopfully they havn't traded them or tossed them. I have a 16 valve head and its screw and locknut or I would have some.

Or you can order shim sets from K&L, Hotcams... Ect.

Pop the cover and write down the clearances and see if they need to be adjusted. Maybe the cam tensioner needs adjustment, cam chain streached? Check timing and see if everything there is lined up as your pick-up could have moved?

But your bike backfiring shouldn't have anything to do with your carbs.

So many issues in that ONE sentence, but let's try to address them:
new o-rings - good, especially if you got the complete kit from cycleorings.com
deep carbs - no clue what you mean here
new pitlot jets - why the new jets?
new main jets same size - again, if they are the same size, why new jets? If they came as part of a carb rebuild kit, quality may be less than good.
new intakes - "intakes" what? Intake valves, intake boots, intake o-rings? No clue here.
new filter - air filter or oil filter?
ran great for few weeks tore aprt - if it ran great, why did you take it apart?
recleaned no help - what did you reclean?
when start the bike it pops back fires like out of time - could be carb mixture, ignition timing or valve adjustment
guy that built motor 3 years ago - ???
i dont know how many miles are on it so im looking for some kinda clues as of what could be the problem. - Odometer does not work, either?
