I'm at around 175 hrs on the original oil pump, I have not changed it because I think the chances of getting a faulty new pump are greater than the current one failing. It's a simple pump and should not be prone to failure. The pumps cost closer to $200 here in Canada.

With the current path of air/oil coming up from the bottom end and fuel only getting to the top of the piston via transfer ports, how is there enough time for everything to mix? I always thought the reason for everything being spun around in the bottom end by the crank was to promote an even mixture of all three headed up to the top of the piston. Just trying to learn.
@slaverace13 жыл бұрын
Jack: Great question. It's actually somewhat amazing that 2 strokes run at all. When studying the 2 stroke engine in detail, it's actually quite magical compared to a 4 stroke. With carbureted 2 strokes, the carb does a great job atomizing the fuel and doesn't need additional help but does get a little as it passes through the ports. Once the atomized premix hits the cases and engulfs the crankshaft, the spinning crankshaft creates arguably detrimental turbulance. Then the piston comes down, compresses the crankcase mixture which transfers the mixture to the top of the piston. At X degrees BTDC the ignition fires the plug during the compression process and "we have lift off Houston". Tpi models go through the same "cycle" but the atomizing is done by the injectors. Many think the injectors produce a stream of fuel but 50 PSI pushes the fuel through several small holes in the injector which produces a spray mist. Hope this helps!

@jackrussell97443 жыл бұрын
Isn’t there an accumulation of oil in the bottom that provides the oil for each stroke? In a mixed gas situation the oil and gas seperate but oil previously seperated is transfered back into the mix. That is how one was to judge (during rebuild) if the ratio used was too lean or rich (size of the puddle). That is how there is enough time. The oil that enters at the same time as the gas gets processed later with other gas. Correct me if I’m wrong here. I make no claims of being an expert.

Awesome video Jeff. I never truly understood how the transfer ports worked. So with my new 21 300XCW TPI, fuel never sees the bottom end then? I understand there is no need for it to be there since combustion is done above the piston. So with oil injected in the throttle body before the reeds and with the incoming air, don't the reeds get gummy from just oil and air going across them? I mean with the carbed bikes the pre-mix I assume always kept the reeds clean. No? Thank you sir Sid

Hey Jeff, Quick question regarding the oil pump.. I have plated my '23 GasGas EC300 and am curious on how the oil pump decides how much oil to send? Main reason I ask is usually a carb 2t will only oil when on the throttle. So actually, a hill with a long decent can potentially damage engine if engine breaking for too long of a period and seize. Does TPI oil pump go off the TPS or RPM or both? If i were riding on the street cruising 55 and let off throttle is the Oil pump going to send less oil because im coasting and not on throttle? Or will it decide since my RPM is at a certain level send "x" amount of oil. I dont ride long distances but only 5-6 miles at a time to connecting trails. Thank you for your awesome products and videos! Ive already learned so much from you!
@slaverace12 ай бұрын
Hello TR5: First of all, carbed bikes use premix that is the same ratio at all RPMs and will NOT damage the engine on long descents unless the pilot jet is too lean. The ECU controls the oil on TPi models and does a good job for all conditions. Worrying about the oil delivery is a big waste of riding time. There are bigger fish to fry.

Fouled two plugs before burning half of it, got frustrated and dumped it out.
