Pjk carburutar jet sizes for rmx250 please! - 1987 Suzuki Samurai

what ever the size they have to both the same size , same jet sizes and same float level settings
the sizing that you have stated don't seem right as they normally come in 1/16 increments not 1/36 increments

KIA does not have a carburetor. It has Fuel injection

boy, you're not asking A LOT here...
I don't even know where to send you besides google forums

Primary Man Jet size # 99-101
Secondary main Jet size # 150
Hope that works.

usually starting issues have to do with the carburetor. especially if it will run well and fast, but if it chokes out at constant high RPM's it could be a flow restriction. If I were going to suggest a thing to do it would be to clean the carb Well. make sure it seals well at both connection ends with no Vacuum leak. after install . If you have moved somewhere from somewhere where it used to run well. you should concider re-jetting the carb . hope this helps

1st, try to ask a mechanic to check if the timing of your engine is correct. the timing might be a little "delayed" so the engine cannot work properly on high speeds.

is your engine still uses carburetor? if yes, replace the primary and secondary jetting of your carburetor. normally, the standard primary/secondary jets for a 1.6cc engine is 105/135.

if your engine already works on direct fuel injector, replace injectors with bigger size. go up 1 size at a time.

i believe the culprit here is the timing in your engine.

THE number should be stamped on the jet if not you can have it sized by contacting summit racing and give them your carb number and they can tell you what was in it from new.

There are no standard jet sizes

You won't need to change the jets. We have had the Cb60 pumping 75- 90kW on the stock carby. Are you trying to increase performance there are better ways: e.g. RHF5 series turbo, lightened flywheel (4.5kg) with Mazda 121 clutch plate and 1600lb pressure plate. Swap in a G202 electronic dizzy& coil, and replace vacuum advance diaphragm.

Carby hat looks like this:

Have you checked the timing? and is it over jetted you may need to reduce the size of the main jets it can be flooding out, you have to make sure the secondary ignition system (plugs wires cap and rotor ) and all good I always recomment Factory AC Delco stuff they have Igh Performance Stuff Too.
