Seems some attempt has been made to do a d shelf mod ( plastic spacer being filed down..) wich means that the bike without adj needle clip is now running plenty lean!  the white spacer normally rests upon the d shelf inside the vacuum slide, so if the spacer is filed down to rest inside instead of on the d shelf the amount it has been lowered should be compensated for by adding washers to lift it to spec, now you have a bike thats running seriously lean in the pilot ciurcuit wich is not good....just noticed the filed spacer.... :)

file the white spacer so it looks like a D shape and place another 3 washers between clip and spacer.... you will  have a big smile after the mod!:-)
The d shelf mod is only done because some claim the needle wears out the needle jet by entering it at an angle therefor wearing it into an oval,  by filing the spacer into a d shape you drop the needle further down the needle jet making the bike leaner.
Trust me....you will be happy with the advice .

Gooi another 3 washers , set fuel screw to 1&1/2 turns out ,when engine is warmed to proper riding temp slowly turn out fuel screw till you get the highest smooth idle once you are there turn fuel screw about a 1/4 turn back, you should be set up after....

Morning Gents!

Only joining this discussion now.

Was never aware of the D shelf mod, but am aware that the needle hangs skew.

Never looked right to me, but left it as is.

If the D shelf mod is not done, to which side does the needle hang? Front/Rear?
