Lancer, When I bought the vm36 from you the initial jetting was perfect with the engine info I gave you,no adjustment needed.
When I added UFO I cut pilot setting in half , from a 20 to a 10 , tried a 12.5 but was too rich ,also added QuadWing too,doesn't affect jetting.
When DAJ was added went from 190 to 170 but still rich,next I went down to 160 power was lacking,currently at 165. Being at 68 ft of elevation am trying to jet so DAJ so most of my adjustment selections are leaner and maybe 1 richer than desired setting
I still have some other tricks for the VM I want to try to further acceleration.
I been tuning Since April and I am getting close. So when it finally goes to Dr Dyno only adjustment I'll need to make will be the DAJ or Intelajet if I upgrade !

Did you drill the little hole in the hood on the top of the needle jet ?

Lancer , No didn't drill atomizer. As you can tell I am a information parasite, I know all kinds of people coast to coast and they in turn know other people and I pick everyone brains that have desired info. Anyways , one night a friend called asking for jetting info for a Yamaha xt500 with a vm36 so we traded info. I told him if he wanted good TT/XT/SR info to get a hold of Dan Whie of White Bros.and little did I know they are friends. So he called him and then called me back with Dan'S jetting specs. Funny how things work sometimes.
Sorry about the long story
Anyways cut the atomizer down I'll have to check spec sheet for how far and also remove air jet !

Lancer , I was told not to drill cause they crack & break off then get sucked in. Lowering atomizer gets things happening sooner as slide comes up and with the UFO should work great.
Remember I'm not after good fuel mileage , I'm after outstanding acceleration
Once you cure the engines breathing problem its all about the pipe & trying to dial the carb for acceleration perfection and that takes as much patience as it does time !!!

The hole allows a little more air through and leans the mix, enabling the use of a larger pilot jet. There is a range in the size of the hole. Why remove the air jet ?

I think they are both related somehow, I will get my books out , get back to you.

Lancer , I would think a hole in the atomizer could possibly do more harm than good to air flow. The shape of the atomizer creates a vaccuum behind drawing the fuel up,drilling a hole in it might disturb that vaccuum.
Spec sheet shows lower atomizer height to 3mm high and as I suspected the air jet is related,the lowering reduces vaccuum behind and removing air jet increases air flow moving more fuel up to atomizer. I think this might help with off idle snap cause almost as soon as slide starts up it starts drawing & atomizing fuel and with UFO & QFW have some awesome throttle response ! Sudco manual shows circuits page 4 fig 6 & 7
Another tiny bit of performance I was missing , there is something wrong with me , most people would have been happy with this carb the way you jetted it , I just wasn't happy knowing I can't get a little more out of it. I so want to finish this bike and get it on a dyno ! Thanks for the help !

Do you have a chart to post or any other info ? Would like to try it before I lower it. So l can compare results. Looking to improve off idle snap. Back to short intake and small foam filter. Thanks
