Dude, you called me bitterfritter... LOL

 

I uses to change it by the book but the screen was always clean, now I just drain the oil tank, start the motor for 10 seconds and it drains the remaining cup of oil out of the crank case with out removing the drain plug. Oil change in 10 minutes now and 3,500 miles and running strong. Same system with out 97 SP500 with 7500 miles.

 

If you don't remove and clean the screen why do you still need to prime the oil pump ?

 

Also there a good cup of oil remaining in the crank.

 

need to reprime pump because you drain the oil out of the crankcase when you drain the oil.Even though you didnt remove remove the screen from the tank.Repriming pump is a precaution to make sure pump is pumping properly. Sorry about your name bitterfitter

 

so you basically run the engine until no oil comes out? not good

 

10 seconds at idle and the extra cup of oil pumps out of the crank and into the oil tank, just the remaining oil residue would lube motor for that time and rpm.

 

This sort of thing is a gripe of mine not just with ATVs but with all vehicles and machinery. For some reason designers don't seem to comprehend that once the things leave the factory they require maintenance. Standard maintenance like oil changes and lubrication should be painfully simple and consumable parts like starters, thermostats, alternators, blower motors, fuel pumps, heater cores etc should be designed for easy and quick removal and replacement.

 

Do you then prime the pump like Ramman67 above says to do ?

 

No' since the oil line to screen was not disconnected or if ramman67 statement is correct ,the crank case drain plug is not removed also.
