i changed the oil on my trike the other day. calls for 4 quarts. after riding for about an hour or so i noticed oil dripping form the air filter. and ofcourse with thw wind and all Oil All over the trike. figuired maybe the trike took less oil then 4 quarts. got home and called the dealer.. he said well, some trike are handle 4 quarts and some need only 3 1/2 quarts. soo the way i took it mine needs only 3 1/2 quarts.. WHAT kind of answer is that?? Has anyone else ever have this problem? also is running it with like 3 or 3 1/2 quarts soemthing i should do?? i dont ever want to go thru this problem again.. besides the trike all full of oil and had to replace the air filter.. that was just soaked and dripping with oil my pants needed a good washing.. had to soak it in dishwashing soap first to try and get the oil out of my pants.. thanks, steve
