oh, thanks for the responses guys. my bike constantly pops on decel, like a LOT of back pressure it seems, many pops but runs like a champ.

 

That's from PAIR.. https://www.superhawkforum.com/forum...ead.php?t=9875

 

oh so it's already removed, so does that mean my mixture must be fine then if that's not what's causing it?

 

LoL.. That the usual culprit for pops on decel.

 

I don't think it's worth the trouble because there are mixed responses about the effectiveness. If you have fins on yours don't worry about it. If you don't you might want to get one soon. if your battery is old, it may exacerbate RR failure??
relative to the carbs, I drilled the largest holes i could around the outer ring of the pipe rear leaving only small amt of metal holding it between holes. Sounds good but not obnoxious.
put .40" shims on needles(remove the little OEM washer).
turned the carbs over far enough to back out the air mix screws with a modified tweezers just far enough to slot them with a dremel and set them at 2 1/4 turns out with a screw driver.
cut paper filter out with a cutting wheel and put foam filter treated with filter oil and sealed with filter grease(KN)
no jet kit.
plug wire resistors removed. PAIR removed

runs good, no popping on decel as before/

haven't sync'd the carbs yet but will eventually/

You can look at color of plugs and pipe ends and tell quickly if you're too rich.


thanks, nathan

 

ill try with 0.026 first to see if any different,do i remove the oem washer or leave it in???????

 

since I posted last, I cut the center out of the exhausts and removed one pipe on each side. No difference in performance, but sounds healthy. The needle shimmed .40 plus other mods listed at bottom of each of my posts. Get it on!
make sure you set the TPS between 450-500ohm while you're in there.
