Use a numbered drill set, measure the jet size using the drill bit set, then select a drill bit two numbered sizes larger and drill out the main jet, that should get you in the ball park.

what kind of ktm is it do you know the year is it two stroke or four. please inform me of the missing info and i'll be happy to help

sounds like your running lean. start with your main jet/needle adj. make sure the bike is pulling hard the WHOLE way to red. after you have that you can work the pilot jet and air fuel screw. Now do you have your air fuel screws 2 half turns out from dead bottom make it one full turn, or 2 full turns and one half from dead bottom. if you have not installed a jet kit there is where you need to start. and please dont forget to sync your carbs when your done.
If you can give me the jet sizes, needle settings and air/fuel screw setting. and we will get this worked out

Intended for motorcycles with a stock engine using the stock airbox, air filter and stock pipe. Stage 1 kits are fully adjustable to allow the use of a well designed aftermarket pipes and stock replacement air filters like K&N. Stage 1 kits are designed to improve throttle response and driveability and in most cases power increases of approximately 5% throughout the entire power range can be achieved.


STAGE ONE INSTRUCTIONS
1. Remove the vacuum slide from the carbs. Remove the stock needles & spacers, noting the order of
assembly. Locate the slide lift holes (Fig. A), with the slide drill DD# 14 supplied, enlarge your slide lift
holes. The picture may not show your slide exactly, enlarge your slide lift hole or holes depending on your
model. Do not drill any new lift holes. Do not drill the needle hole.
2. Install Dynojet needles on groove #4, using all stock spacers. Install the Dynojet washers (2 per
needle) above the E-clip.
3. Remove the stock main jets and replace with the Dynojet main jets provided. If you are running with
stock exhaust, use the DJ110 main jets. With an aftermarket header or slip-on with high flowing baffles,
use the DJ116 main jets. Be sure that the jets you are changing are the main jets.
4. Locate the fuel mixture plug (Fig. B), if you see a screw head, proceed to adjusting procedure. With the
DD #5/32 drill bit provided, carefully drill thru the plugs. Note: the mixture screw is directly underneath this
plug, be ready to pull back on the drill the instant you break thru. Use screw provided to secure and
remove the plug. Carefully turn mixture screws clockwise until they seat, turn out 3 turns.

The secondary main jet (125) goes into the jet needle holder in the center of the carb (needle). The primary main jet (75) is between the secondary main jet and the pilot screw (this one is slightly off center) . The start setting for your air screw should be 1 3/4 turns. Warm up your engine and drive for ten minutes. Adjust your idle speed to 1100 + or - 100 rpm. Now turn pilot screw in or out to get highest idle speed. Readjust idle to 1100 rpm. Now turn pilot screw in till idle speed drops 100 rpm. If pilot screw seats go to next step. Adjust the pilot screw out 1 full turn from 100 rpm drop point. Now reset Idle to 1100 rpm. That is how Honda says to set your air screw. Standard setting is probably sea level and going through the procedure will set you up for the altitude where you ride. Do the adjustment during good weather at the altitude you plan to do the most riding.

Start with setting the air and throttle screws. Turn each one inward until it GENTLY seats. Back each one out one and one half turns. Clean the air filter and starter plunger. The plunger may need to be rebuilt or replaced. Check the pilot and main jet sizes. There will be a number stamped on the side of the jets. The pilot jet should be #45, the main jet should be #140.

The idle jet is located in the bottom of the car. it's the recessed one in the bottom of the body. Remove your air cleaner assembly. remove the four screws. Be careful because it will be full of gas. ( well vented area.) You'll have one jet sticking out. That's your main. right next to it is a recessed jet . That is your idle. you'll have to use a small flathead screw driver to get it out. Make sure you have god pressure on the jet to break it loose. The jet itself is brass, and you don't want to mess it up. You should probably have a 45 jet with your combo. if you've been messing with the mixture screw it should be set around 1 & 1/2 turns out from lightly seated.
