I am ordering the HMF Utility pipe Friday. But its the loudest out. The HMF QS1 is supposed to be relativly quiet. There was anothe rpost on here discussing it.
feel free to take a look and see what jet they used and where they put it for me mine should be the exact sameI just let the local motorcycle shop jet mine. It wasn't cheap but it was dead on. After riding this weekend (first long ride w/ the Utility pipe), the spark plug looked good. Maybe a tad rich. It may need a 1/2 turn in on the mixture screw. I am going to ride it again and see how the plug looks. It runs great though and you will feel the increase in power.
could probably use the help thanks.ill put it in for ya. I gotta jet my dads bike today the hmf should come today i hope.
Its a DJ 170 jet with the clip on the middle notch and I have the mixture screw 2.5 turns out, but it may need 2 or 2.25 out.feel free to take a look and see what jet they used and where they put it for me mine should be the exact same
