Thats not a chip, look again, it seats into a corresponding impression inside the slide ! If you rotate it you will feel it slot into place.
Anyway, it's history .... they say leave it out ! ??
Ok, lets go to the slide.
Take off the main jet and remove the nozzle out through the top of the carb, then pull the whole slide guide out and look for the O-ring under neath.
Get the slide and slide guide together , really look at it for wear, at the bottom edges ....
Lets see how that looks, you have to build from there.
If it's really hammered, your new fancy dynojet needle is going to be worn and useless in the next 8000km ....
This is where you have to face facts.
Lets first ID your carb, outside on the left should be a number. Mine said 12EF // 411 , yours will be more modern I think, as already your needle has slots, mine didn't .
Whats the number on the needle that came out ? 6F10 or later ?
Get the nozzle out ! 691- y2 or later ?
Take your time, open a beer. ZENNNNNN !!!!!!!! This is the part you DO NOT rush !
