What is the WH number on your carbs. With it I can tell you what the factory put in there.

If it has stock jetting: MAINS: TOP carb. cyl. 1=.074; cyl.2=.076; CENTER carb. cyl.3=.074; cyl.4=.074; BOTTOM carb. cyl.5=.076; cyl.6=.074;

IDLE: .046 ALL cyls.

VENT: cyls. 2 and 5=none the rest are .096

This also depends on your location above sea level. 2500'-5000' -.002" than above sizes; 5000'-7500' -.004"; and 7500'+ .006" smaller.

If it were me and it has the stock jets, I wouldn't change them till I ran it and checked the "piston wash". Be sure to check it at WOT and cruise speed.

Hope this helps.

hey,cyl 2@5 have a 94 vent jets. should i remove them?

 

[jkeiper]

Naw. If it runs ok now I would leave as is and just watch it close after you add the reeds and tuner. Those two things are not that drastic.

hey, just wondering why cylinder 2 and 5 have a 94 vent jet when the book calls for none on those 2 cylinders. should i remove them and leave the holes open? i have been told to make sure everything is stock to begin with. thanks
