What a difference .030" makes!!

Is it still too lean at half throttle?
Hard to tell from here.

sooo..... if .030" makes a big difference, will .050 be better?? What's your experience?? The bike(s) are completely stock through & through.

Did the same thing on my 850 recently and it made a very noticable difference; choke can be turned off shortly after starting now and the flat spot at partial throttle is completely gone. Highly recommended modification for all GS bikes with BS/CV carbs.

I raised the jet needles in my son's '82 GS650G up .030" and that flat spot between 3-5K disappeared!!

I should also note that I re-adjusted the mixture screws because it was running quite lean too (each screw is now out approx 2.5 - 2.75 turns)

Now you can cruise in 5th at 2700-3000 rpm, turn the throttle and actually accelerate nicely!! \\/

My plan is to do some plug chops & adjust from there.

I'm still smilin' though !!!! :-D
