I was thinking of going Synthetic on my evo till I got some input here. I'm thinking of trying a 2,000 mile stretch of Super Tech 20w50 and having it analyzed. In my opinion 2,000 miles on a batch of crap oil won't kill your engine, but 30,000 on the same crap oil will. I change oil every 2,000 mile in my harley anyway. If I don't like the results I see I'm using Castrol GTX 20w50. On what I read it gets great results (castrol), and I've been using it in my cages since I first started maintaning my dad cages. Most of my cages get HM because they're all paid for. It's only worth financing a scoot. They never made different oil for Corvairs, porches, and volkswagons did they. Those vehicles probly run hotter than a Harley EVO.

I ran synthetic in my evo and it was noisy and seeped. Will be running 20/50 castrol this season.

Will try the Castrol 20/50 and see how it does. The link I posted recommended the GTX. Thanks alot ya'll. I used to work in a bike shop back in 1996 but pushed Rev-Tech. Can't make money telling people they can go to K-Mart for oil. I mainly did pre-evo work but a lot of guys told me about the Valvoline. Always liked my old Ironhead but decided this year to upgrade.

I run Castrol GTX 20-50 in my 99 EVO. I bought it two years ago from a fellow that had 5 Harleys, and ran it in all of them. Mine had 17,000 on it when I got it, and now has 27,000 on it. I have heard so many good reports on GTX that I think I will probably stay with it. I do change oil and filter about every 2,000 to 2,500 miles. I never have to add between changes, and the motor is quiet. I changed out the INA cam brg. recently to a Torrington, but the cam and brg. still looked like new. I had no sludge in the cam case. It was clean as a whistle.

I noticed the tank had sludge in it so I washed it out with K1 and ran the oil out of the lines and will fill it with Castrol GTX 20/50 and gonna pull the primary to check the starter clutch and ring gear (other post starter chatter) and fill with same. Thanks for all the input.

Like V-Twins&Bowties said,don't put engine oil in your primary,you'll probably burn your clutch plates.

Running Amsoil 20W50 on the FXR almost 2K Miles now and no signs of any oil leaks, or excessive noise.. No idea what the previous owner used the first 16K on it..
