Thanks for the post Roger...proves what we've been talking about on here for the last couple of days, and before on other threads. Both products will do an excellent job, are less expensive than syn3, etc. [smiley=xyxthumbs.gif]
Jerry...also excellent points concerning pressure, volume, etc. Since we don't know the flow rate capabilities of the Twin Cams, it is a "best guess" scenerio, and it would always be better to err on the side of higher pressure, all other things being equal. If you've got the engine apart to do the cam, gear drive, and other mods, and can afford the extra bucks for the pump and lifters, it's just insurance, and relatively cheap insurance at that. Just running the good oil in a basically stock engine, with the stock pump should make everything alright and take the worries away.
Hogfn...The local dealer here did not want to put the Mobil in my bike when I took it in for the 1K service, even though I had the oil in the tourpak. Rather than getting into a pissing contest with them (I did not buy the bike from them, but from Mobile HD), and knowing that if I had any real warranty problems or call-backs, they would be the ones who would have to do them, I just let them put syn3 in, then changed it 50 miles later myself. 60 bucks literally down the drain. From this point forward, on the service intervals and things I do not feel comfortable doing myself, which are becoming fewer, I will simply change them myself prior to taking it in, and not allow them to change the fluids, but do everything else. Hopefully, your dealer is more reasonable, and will allow you to use a superior product in your scoot. The two dealers here in Birmingham are owned by the same person, so I didn't think it worth the risk of getting bad blood started, though I was tempted. Technically, if they refuse to put an oil of your choice, which meets or exceeds their specifications (which Mobil and Amsoil both accomplish), they have to GIVE you their oil...I don't want the chit in my motor, even if they do give it to me, and the argument that would ensue, would accomplish nothing other than to get my blood pressure up, so I'll just let sleeping dogs lay.
