Go to the NSR site it has a lot of info including the fuel curves I think.

It shows the circuit it looks like you can choke the air bleed with a insert or jet, or increase the taper on the end of the screw
I added them as an attachment in the last post.

Fuuuuuuuuuuck.

i wish but its a nsr250 2 stroke carb hence the time to make it work , how do i chance the air screw to give it more fuel as its right in now

you would have to put bigger pilot jet in, wont matter what you do to the screw once its closed, you cant get it any more closed, despite the efforts of many before you

It will be interesting to see if you can hit 30 with that size carb. I am going for a 34-35mm on my bucket. I know the FXR head I have will flow enough air for 35hp at the moment its close to 27. And the KTM i was building was going to be 38mm injected. Can you go bigger. I know you have my old NSR carbs they can be bored out quite a bit.

We all know the DynoJet dynos read a little bit optimistic but reasonably consistent between different DynoJet dynos. I had the impression the Team GPR dyno was more straight up. Does anyone have a feeling for how the GPR dyno compares to the Dynojet we use?

Pretty sure they posted a bog stock fxr result on it somewhere.

we set are's as close to a dynojet as possable , i always thought my old dynojet read right as all standard suzuki bikes read right to manafactures specs with in a hp , on the track regans bike v some of your bikes you have worked on with same kind of hp and bike rider weight look not much in it , bit hard to compere with me as i'm over a 100kg lol

Seams very close to yours rob. My FXR has been on both and read the same.

i have 2 38mm fcr carbs , a little big for a carb but know for injecting 2-3 mm is about right . i could sleeve one
