At start up engine runs at very high ilde and wil not kick down to regular idle. Just replaced throttle position sensor.


Check coolant temp sensor untit. It tells the computer what the coolant temp is at and adjusts the cold start accordingly. If its bad it'll stay on high idle until it warns up.

Idle speed around 2000 rpm, 1st ride of the year , had this issue. I followed my Manual info and adjusted Cold and Hot adjustments. When restarted the idle was close to normal, but after a minute or 2...


Adjust the idle speed ONLY when the engine is at full operating temp. It should be idled at about 1000 RPM. It will probably be too low when cold and you may have to use the throttle control to keep the engine running until it gets completely warmed up. On the carburetor equipped engines, you cannot adjust the bike where it will idle cold and not be too high when it gets hot. The only way you can get this is with fuel injected models.

Good Luck

My 2000 suzuki katana has a high idle when its hot


This is a fairly common problem with performance bikes. The problem comes from your thermostat. The thermostat is designed to open and close at a certain temp. What I suspect is happening is that your thermostat is opening too early for the bike to get to operating temp, hence the long time to warm up. Once you open up the bike warms up and the oil viscosity thins to operating temp and the engine revs more freely. Now your idle screws are set for a "cold" bike and revs high.

The other side is that the oil you are using may not be designed for your bike. Often people put performance synthetic oils in their bikes to perform better, but the production bikes are designed for thicker oils. Oils like 5w40 will be very thin allowing your bike to rev faster due to thinner oil, but you are causing extra wear on the parts due to less oil barrier.

First I suggest make sure you have the correct spec oil for you bike, then check that you have the correct thermostat in your cooling system. A performance bikes usual operating temp is between 95-105 deg C. This means your thermostat should only open at about 88deg C to start the regulation process.

F33 or F34 codes may be triggered by either excessive heat within the oven or poor grounding of either the temp sensor or the controller (DPU) board. Check the following:

a) Clogged air filter (not applicable to OCS models)

b) Obstruction of the exhaust duct or insufficient ventilation

c) Defective thermal sensor (should read 30 – 70 kohm in room temperature)

d) Grounding of the thermal sensor (possible oxidation)

e) Poor connection (oxidation) at CN4 connector (PRO-1 models only)

f) Poor or no ground at the controller (DPU) board – ensure that all screws securing the board are in place

g) Missing screw(s) that secure the escutcheon to the frame (OCS models only)

h) If all steps above check OK, the error(s) may be caused by defective controller (DPU) board
