you can but it will only damage your valves and make short life of your engine
CRF is 4 strokes... The ( F ) at the end means FOUR !
take out the baffels in the end can
No a crf is a four stroke. The F at the end means fourstroke. a cr is a two stroke.
With a four stroke engine the ignition timing is set at towards the end of the compression stroke. A novice make make the mistake of setting it at the end of the exhaust stroke. So yes it is possible. However the engine will not run.
Pedal bike, definitaly a full suspension with a 24 in. rear wheel the small wheel makes it eaiser to get the front end up Dirtbike, I'd go with a four stroke because of the power control. I have a Honda TLR 200 and it Wheelies as long as you want
A 4 stroke has more usuable power because of low-end torque as opposed to 2 strokes which has more wheel spin because of instant power. (wheel spin= less traction, [2 stroke]. less wheel spin= traction, [4 stroke torque].
no compression (easy to push kick starter down)
The CRF150F is a trail bike, soft suspension, not as much power as the r, air cooled engine. The CR150R is the motorcross version, more power (21 hp), water cooled, taller suspension, less low end power, you have to keep it at high rpm's to get all the power. They are quite different.
a 2 stroke in the end is a better choice. yes it is true that a 4 stroke gives you more power, and it doesn't over heat as easy, but a 2 stroke will cost you less money to fix, less money on oil and gas, plus a 2 stroke has better initial speed, and a higher speed band. ^^ Actually 4 stroke MX bikes are the ones that are prone to overheating, and if you dump a 4 stroke after an hour in the woods, good luck getting it started again.
The spark plug will fire once every four strokes, at the end of the compression stroke.
A two stroke with near the same displacement will be quicker to accelerate, but will lack in low end torque and reliability. The four stroke will last for ever but just doesn't perform or rev like a two stroke. "I agree 2 strokes are much faster. A Quadzilla lt500r 2 stroke will scramble with the power feel of a gsxr 1000 four stroke .You have to double the displacement of 4 stroke to compete with a 2 strokes powerband. Research the definition of "POWERBAND"
The rebuild cost of a two-stroke dirt bike can vary significantly depending on the bike's make, model, and extent of the repairs needed. On average, a top-end rebuild, which includes replacing the piston, rings, and gaskets, can range from $300 to $800. A complete bottom-end rebuild may cost between $800 and $1,500 or more, depending on the parts and labor involved. Additional costs for performance upgrades or aftermarket parts can further increase the total expense.
