how did it run before the uni filters and jet work? Did you get adjustable needles? See if it won't accelerater you are either too rich or too lean, but since you increased the mains I would guess its too rich. Try dropping to a 105 or whatever is available that is close to that size. If it improves your problem but doesn't eliminate you can keep going down mains until you find the one that gives you the best top end. Once your main seems to work right time to work on the secondary mains if you have them, then needles, then slow speed/ idle mix. The correct way to rejet is to work your way down from the mains until your bike runs well everywhere. With out the correct testing equip (dyno, and gastesters) its all based on trial and error so be prepared to take the carbs off alot. Its pointless to mess with needles and anything below mains until your top end is right. As far as cracked boots its more likely you would notice an issue like that in you low end since it would reduce vaccum the bike would want to die or stumble at idle.
