hey, i have a 1986 polaris trailboss and does the same thing. does it start studdering after half throttle? mine does, runs perfectly fine befor half throttle then as soon as u go past that, it starts studering and has no power. if you find anything, let me know, thnxs
two stroke engines have a power stroke every second revolution of the crank shaft. four strokes have a power stroke every fourth revolution of the crank shaft. that is why a 125cc two stroke has about the same power as a 250cc four stroke.
2 stroke, more power and torque = more speed 4 stroke, more reliable
mine has been up to 49.4 on dirt speed checked with a garmin e-trax gps
Really depends on what kind of power you want. a 2-stroke will tear through it's gears faster and overall accelerate faster. 2-stokes have a wider, harder-hitting powerband where the power is mostly at high rpms. a 4-stroke has the low end power- no clutch wheelies, tearing the bead off the tire..so which is more powerful? all depends on when you want the power. 4-strokes low speed, 2-strokes mid-high speed
Usually, it's the other way around. For the same fuel, engine size etc, 2-strokes will spin faster than 4-strokes. if it's about the speed of the vehicle, the big thing isn't 2-stroke vs 4-stroke, but power, or power-to-weight ratio. For the same amount of weight, a 2-stroke can make more power than a 4-stroke. But in a vehicle where weight isn't that important, the vehicle that makes the most power is likely to be the faster.
clutch slipping????
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.
a 125 2t will have a lead in the start because that's the thing about 2 strokes they have alot of speed but the 250 4 stroke will definitely win given that the engine is bigger and that 4 strokes have more traction and power..............
yes engine displacement plays a big part. Also important is if it's a 4-stroke or 2 stroke. 2wd manual or 4wd automatic( the latter has more drivetrain power loss). Gearing on a modified quad has a big impact on acceleration/top speed.
What size 4 stroke dirt bike would greatly vary your top speed. A 125 4 stroke will top out around 48-50 mph while a Honda XR 650 4 stroke top speed is just a bit over 100 mph.
any old lambo because a ferrari doesnt have as much horse power and speed as a lamborghuini
The camshaft operated the inlet and outlet valves in the cylinder to admit fuel to the engine before ignition and expel the exhaust gas after the power stroke. The camshaft operates at half the crankshaft speed in a four-stroke engine.
