Nc29 air/fuel mixture adjustment

Post by dunkenb » Tue May 22, 2012 11:38 am

Is it possible to adjust the air screws on an nc29 without taking the carbs off every time?

Well I cant do it on my 29 but apparently you can use an angled screwdriver, I think you will find one on ebay or one of those bike shops that sell odd items.

hi all, thinking of doing the same to my nc29 she seems flat at the down,
question is which way do you screw the screw in to richen it up as you look at the screw if you know what i mean.......
also does the setting of this mixture screw effect the mixture throuout the rev range.
Thanks for any help guys,
sorry to jump on this thred but its related
Regards Phill

screw in for leaner. Out is richer. Only adjusts up to quarter throttle.for that you need to change needle and main jet settings. :grin:

it effects the whole rev range to a degree, but use it to adjust the idel- 1/4 throttle spot on and then change other jetting independantly.
