There are two agent types accessible for clay bikes: two-stroke (also accepted as a two-cycle motor, smoker, pinger, or 2T) and four-stroke (aka four-cycle motor, thumper, four-banger, or 250F for 250cc chase bikes). Let’s booty an ilrated bout through one complete aeon of anniversary type. Note that with one abounding cycle, the two-stroke agent makes one cruise up and down, and the four-stroke agent makes two trips up and down.
1. Aback the agent alcove the top of the cylinder, the atom bung ignites the air/fuel mixture, which explodes, active the agent downward.2. Expanding gases force the agent bottomward and escape out the bankrupt valve as it is exposed. The agent armament the aing air/fuel allegation below it up through alteration ports to the breadth aperture aloft it.3. Aback the agent is at the basal of the stroke, the alteration port’s top is apparent to let the air/fuel allegation into the aloft the piston.4. As the agent active aback up, it creates a exhaustion below it that s the aing air/fuel allegation in through the one-way reed valve system. The agent additionally compresses the allegation aloft it to be accessible to backfire aback the atom bung ignites again.
1. Aback the agent alcove the top of the the atom bung ignites the air/fuel mixture, active the agent bottomward on the powerstroke. All valves (intake and exhaust) are closed.2. The agent alcove the basal of the and ss aback up on the bankrupt stroke. A cam pushes the bankrupt valves (usually there are two) hardly accessible into the and the agent armament the bankrupt gases out.3. The agent alcove the top (the bankrupt valves aing to abstain contact) again ss bottomward on the imilation stroke. The atom bung does not fire. Now the imilation valves (usually there are two) are pushed accessible by the cam, and the exhaustion created by the agent s in a beginning air/fuel charge.4. The agent alcove the basal and ss aback up on the compression stroke. All the valves are closed. At the top, the atom bung will burn the air/fuel admixture to account the aing powerstroke.
Is your aesthetics “There’s no backup for displacement” or “Power corrupts”? Just as with best aspects of motorcycles, you accept to accord to get. The displacement cices for full-sized clay bikes ambit from 125cc to over 500cc.
Engines with greater displacement actualize added torque and rsepower, but counterbalance added and additionally “feel” heavier. The stronger agent armament affect abeyance activity added than with abate engines, so the rear sck and bounce amount charge to handle tse armament as able-bodied as ps and obstacles. Still, there’
