When tuning a KTM 85 SX with a power pipe exhaust, it's typically recommended to start with a main jet around 160-165 and adjust as necessary based on performance and conditions. The pilot jet might be best set around 45-48, depending on your riding style and altitude. Always monitor the spark plug color and engine performance to fine-tune your jetting for optimal power and throttle response. Remember to consider factors like temperature and humidity, as they can affect jetting needs.
If your power band in your KTM 65 isn't functioning properly, it could be due to several factors. A common issue is a dirty or clogged power valve, which can prevent it from opening and closing as intended. Additionally, check the carburetor for tuning issues, as improper jetting can affect performance. Lastly, ensure that the exhaust system is not restricted, as this can also impact the power band's effectiveness.
ktm 65's are pretty much as good as you cant get when there stock, although you cold adjust the jets a bit and get suspension upgrade. the ktm exhaust pipe is the best some say although fmf do a slightley thinker versionn as sometimes stones pentrate the stock pipe. butthe again some say a hgs exhaust or such like fmf or pro circuit.
In your carburetor. You have a main jet and an idle jet.
yes it would fit but you need to change the exhaust flange at the front to a 1999 because 99 ktm;s have a concave outlet so the exhaust slips in i know cause i have a 99 ktm 125sx that am rebuilding and i have just purchased a 2001 exhaust flange to fit a 2000-2003 exhaust........simples
To achieve proper jetting for a 2005 KTM 525 EXC, you should start with the stock jetting as a baseline, which typically includes a 165 main jet, a 42 pilot jet, and a needle positioned in the middle clip. Adjustments may be necessary based on elevation, temperature, and modifications to the exhaust or air intake. It's crucial to check the spark plug color after riding to ensure optimal fuel mixture, aiming for a light tan color. Fine-tuning may involve moving the needle clip or changing jets to achieve the best performance and throttle response.
Yes it is a two stroke But if u want to check the exhaust pipe is thin then it's a four stroke If it is thicker it's a two stroke
Put upgrades on it like fmf pipe and big bore kit
the base horse power for a ktm adventure is 100 horse power
IMO, Ratio depends on the carb jetting and oil quality. Try 32:1 (gas:oil) using good synthetic or syn-blend then jet the carb. With stock jetting that should be in the ballpark. Higher altitudes will require leaner jetting (smaller jet size not different gas:oil ratio).

Pro Circuit pipe for KTM 50 is between $199 and $250 depending on where you buy one.
Check your premix ratio, carb jetting and make sure you are running the right spark plug.
