Slide in carb in backwards??

9 posts in this topic

Hey guys, a while back (cant find it in search now) i told you guys that my bike would backfire on decel and i have a 50 pilot jet and 3 turns out on my mixture screw. Someone said that possibly part of my slide was in backwards. I just got back of holidays and removed the carb and took pics front and back, can someone tell me is this right or is there that condition on my bike, I need to know asap before i put it back on. Thanks guys.

Attached are a couple of pics.

Mine looks just like yours, except my slide won't go all the way down now for some reason...

Ok, i guess I will shove it back in again. still have to work out why she's backfiring though on decel with the mixture screw out any less then 3 turns, upped from 48 to 50 pilot jet and it's still exactly the same thing, only now i can start it when cold without using the choke so I know I should be too rich there. Maybe there is something else i can try..

Ok how do i disable it? I have removed the smog pump thing already, is this the air circuit on the side of the carb? BTW i have my bike done all to yz specs, exhauset camshaft, timing, exhaust. ..... can i go back to 48 pilot then or what other changes do i need to make after modding the ais?

this ais is long gone, i bought the ais removal kit from yamaha first when i bought the bike, i though you meant the air cut valve, maybe i need to mod this so it would be more like the Yz 450 as everything else is.
