i had a hell of a time tuning after the pod set up ..but i also switched to straght pipes in the long run it was worth it love the way it look's and sounds now

use a small flatblade screwdriver to hold it in place to keep it from spining , than use a pick tool to pry it out . that's what i did . if it's rusty and nasty than give it a spray with some WD40

ive had my XS400RJ pop up once when i down shifted from 2nd to 1st then gunned it WOT . i cant say it was fun tho

i changed to same size for both carb's when i did my mod's "straght pipe's and podfilter's" after the change to a bigger jet size the side with the smaller jet's was way to lean. i then went to same size for both side's as i went up in size . i think the reason for the offset jet size was for emission's. ive got a bit of lag in the low rpm's cuz of the pipe's but it pull's up to 115 mph from 65mph fast

does it just fall flat on it's face @ 6k and pick back up ? sputter and backfire ? any surging . have you cheaked the plug's for to lean or to rich?

pull the carb's clean'm real good and go up 1 size on the jet's . reseal the intake manifold's to the head's to make shure you don't have any leak's there . re-install the carb's and sync them up and go from there ...

try some local cycle supply shop's . that's where i found mine they had a big ol box of them @ the counter next to the big one's .

i'm runnig the uni filter's on mine . there well made and work fine . i tried the one's from mikesXS. the rubber was cheap. i'm willing to bet you will for shure have to re-jet btw you can also get a prefilter sock for the uni's

if you go with PODS you may have to rejet but it's not that big of a deal and you get to know more about your bike. i would go with the advise you got in your thread about it. try making some and see how you do . go down to the local cycle shop and see what they might have to use ?

if that inlet valve was to some how work it self loose it could cause alot of trouble

last time i took my bike out it started to run like crap halfway thru the day . yesterday i pull'd the carb's to give them another cleaning . when i pulled the top's off the diaphram's look what i found ! ive pulled this off many times to check for pinhole's and stuff but dam. look's like it was from when the carb's where made just some random bit left over from drilling hole's in the carb body . it made a nice hole in the rubber to. i fixed the hole with liquid electrical tape seem's to be working well the stuff i got is realy strong .

just cut the old grip off with a razorblade or a sharp knife . hairspray work's good if it's real hard to get the new one on
