Warrior jetting
Have a 99 warrior has stock jets 42.5 and 145 aftermarket exhuast fmf slip on was popping /back firing and also have k&n filter so went up on jets 1 size 45 and 147.5 and now starts but idles low mess with idle screw and wont start and when it does still pops out exhuast so my question is do i need to possibly adjust the idle and fuel screw on the outside of the carb to adjust with the bigger jets? Any help will he appreciated.

With new FMF exhaust, 45 pilot, 150 Main, new foam air filter, and cleaned/polished acc. pump, which had crusted /hanging up, plus added a plastic tip, made from silicone caulking tube tip, drilled out with 1/8 bit, which then fits real snug over acc pump rod, which then extends acc. pump rod an additional 1/8th inch, allowing fuel to squirt instantly, without any hesitation (as it had before the work/cleaning) as soon as the throttle is hit! Running now like a raped ape! Smooth, and quick out the gate, no more sputtering/popping on any gear, especially at idol, or lower rpm! Much quicker/faster than my TRX450r, and being seated lower in the saddle, allows for quicker turning at higher speeds through tight trails....it's a fire breathing beast now, with only doing these few cheap tricks, compared to stock, and given its age when parts do tend to dry out, needing cleaning or replacement! No need to touch stock needle, or the unneeded opening up of air box! Couldn't be happier!
