this could be a number of reasons it could be your mixture screw or it could be running lean or rich the best thing to is a plug chop see what colour it is if its black and oily its running rich if its white its runing lean also if its running lean your engine will sound flat and could course it to seize or the main jet could be to big or to small its always best to over jet a a 2stroke and work down till you feel the engine getting better hence the bog going away hope this helps
A 1993 Honda xr100r would have a four stroke engine.
The intake stroke, number one in a 4 cycle engine.
Assuming this is the 4.3 engine, the throttle body would be found on top center of the engine. The air filter assembly would have to be removed to get a full view of the throttle body.
No it isn't fatal, but it would smoke quite a bit, because a two stroke engine needs two stroke oil mixed in the petrol, and a four stroke just needs petrol.
A throttle is the controls and mechanism that controls the flow of fuel and the fuel/air mixture into the engine. The throttle would be a part of the fuel controls on top of the engine of most cars.
a stroke is a half rotation of a crankshaft. a three stroke would finish would only be 1 1/2 revolutions.
90 degrees would be a half stroke.
No, definitely not. If you could, there would only be one oil for both types of engines.
That would depend on whether the engine is a 2-stroke or a 4-stroke. You can determine by looking for an oil filler spout or filler cap on the engine. If it has one, the engine is a 4-stroke and the oil is added through there. If it doesn't have one, the engine is a 2-stroke and 2-cycle oil must be added to the fuel in the recommended ratio.

Large vacuum leak. Check the hoses that hook to the intake manifold.
The throttle body is where the carburetor would be on a non-fuel injected engine. Trace the air duct from the air filter to the engine, that's where you will usually find it.
