k2 bandit loping idle

Hello lads hope ye might shed some light on this or point me in the right direction.
I have an 01 k2 bandit 600 which sounds like an offbeat subaru boxer engine until about 3k moreso when warm. Its fine after than and goes like stink from 5k on
Here is what is done to it-
1 valve clearance adjusted 400 miles ago
2 timing advanced about 3 deg
3 pair removed
4 needles shimmed .47mm
5 balanced carbs last week-perfect although i have heard i should leave slightly more air into the 2 outside cylinders--anyone else heard this??
6 throat removed from airbox
7 pilot needles out 2 turns
8 carbon can
standard air filter,clean oil and about 1000m up on the plugs
the carbs and seals are all clean and perfect.
Today then i took the baffle out of the carbon can and it made it much worse and added a load of small pops and farts off throttle-there is air getting in at the collector box so id assume where thats coming from.

So guys any ideas what might be causing the lumpy low range???
any help would be greatly appreciated

loping idle ?????????

Your mixture is too weak on the pilot jets,these work mostly up to 3,000 rpm.

More air on the outside cyls (cooler running) is sorted with the jets being different sizes.

OH and welcome.

Also lasses on here as well.

Hi Pajomad and welcome to the site:smile

I would think the 3degrees of advance would effect the bottom end quite a lot,but as jaffa says i would also recommend a trip to a dyno to set all the carb mods up with the ignition alterations,Good Luck
