a few months ago i posted i thought i have lost some rpm over the last couple years, so i checked compresion on my 500efi and was low, 140's. most on here said doesnt matter do a leak down test. for other reasons ive had to have the moter pulled. hallet did leak down test they said it did great? it was 8-11 percent. everything i read says thats a bit high for a babied motor with 150 hrs??? also they are reccomeding ahaving the fuel injectors removed, tested, and cleaned while its out???
