I know many people that use a jet drill kit to drill out thier jets. I was looking for the true hole size for a while. Here's the data: (Width = true hole diameter) Width------Keihin # -- DynoJets # -- Mikuni # 0.0350---- 92.5--------- 92---------- 86.3 0.0360---- 95----------- 94---------- 88.1 0.0370---- 97.5--------- 96---------- 90.0 0.0380---- 100---------- 98---------- 91.9 0.0390---- 102.5------- 100---------- 93.8 0.0400---- 105--------- 102---------- 95.6 0.0410---- 107.5------- 104---------- 97.5 0.0420---- 110--------- 106---------- 99.4 0.0430---- 112.5------- 108--------- 101.3 0.0440---- 115--------- 110--------- 103.1 0.0450---- 117.5------- 112--------- 105.0 0.0460---- 120--------- 114--------- 106.9 0.0470---- 122.5------- 116--------- 108.8 0.0480---- 125--------- 118--------- 110.6 0.0490---- 127.5------- 120--------- 112.5 0.0500---- 130--------- 122--------- 114.4 0.0510---- 132.5------- 124--------- 116.3 0.0520---- 135--------- 126--------- 118.1 0.0530---- 137.5------- 128--------- 120.0 0.0540---- 140--------- 130--------- 121.9 0.0550---- 142.5------- 132--------- 123.8 0.0560---- 145--------- 134--------- 125.6 0.0570---- 147.5------- 136--------- 127.5 0.0580---- 150--------- 138--------- 129.4 0.0590---- 152.5------- 140--------- 131.3 0.0600---- 155--------- 142--------- 133.1 0.0610---- 157.5------- 144--------- 135.0 0.0620---- 160--------- 146--------- 136.9 0.0630---- 162.5------- 148--------- 138.8 0.0640---- 165--------- 150--------- 140.6 0.0650---- 167.5------- 152--------- 142.5 0.0660---- 170--------- 154--------- 144.4 0.0670---- 172.5------- 156--------- 146.3 0.0680---- 175--------- 158--------- 148.1 0.0690---- 177.5------- 160--------- 150.0 0.0700---- 180--------- 162--------- 151.9 0.0710---- 182.5------- 164--------- 153.8 0.0720---- 185--------- 166--------- 155.6 0.0730---- 187.5------- 168--------- 157.5 0.0740---- 190--------- 170--------- 159.4 0.0750---- 192.5------- 172--------- 161.3 0.0760---- 195--------- 174--------- 163.1 0.0770---- 197.5------- 176--------- 165.0 0.0780---- 200--------- 178--------- 166.9 0.0790---- 202.5------- 180--------- 168.8 0.0800---- 205--------- 182--------- 170.6 0.0810---- 207.5------- 184--------- 172.5 0.0820---- 210--------- 186--------- 174.4 0.0830---- 212.5------- 188--------- 176.3 0.0840---- 215--------- 190--------- 178.1 0.0850---- 217.5------- 192--------- 180.0 0.0860---- 220--------- 194--------- 181.9 0.0870---- 222.5------- 196--------- 183.7 0.0880---- 225--------- 198--------- 185.6 0.0890---- 227.5------- 200--------- 187.5 Keep this in mind---> From a Dynojet tech rep: We are often asked for a "cross reference" sheet that compares our main jets to Mikuni or Keihin. The fact is you cannot directly interchange the jets for a given size. Many things affect fuel flow through a jet of the same orifice size. The entry and exit tapers of our main jets differ from those of other companies. Due to this, the fuel flow changes as a function of velocity through the carburetor venture. This means that two jets of equal orifice size will have a different fuel flow curve relative to intake air speed. At a certain speed the two may flow equally, but a change in velocity changes the flow characteristics. The Dynojet main jet hole size is measured in millimeters. For example, a DJ142 has a 1.42mm hole. Michael Cory Research & Development Phone: 800-992-4993 EXT. xxx Michael@Dynojet

О, хорошая табличка. Только в читабельный вид её привести бы.
