I would just put any good but cheap 10w 30w oil in and drive just long enough to warm it up and then change to a syn oil. I have used a product that cleans the sump in cars before, but I would not use it in a bike.

Don't know about flushing or flush kits but, in the cooler season, I run 15w40 Rotella Deisel grade oil. Engine oil designed for Deisel are said to have more detergents than other engine oils ( holds up better in high heat and carry more load too,they claim). Seems to keep all my engines clean inside.

why, cause amsoil is so awesome that it doesn't get contaminated from use? doesn't matter what you use, the oil is gonna get dirty. dude just wants to make sure that he gets all the old, dirty oil out. you, on the other hand, don't care about that last little bit of dirty amsoil that you are leaving behind. your call.

I'm sure it wouldn't hurt to flush out the engine oil system in my '92 Heritage.
I had an oil change about 30 miles ago, and the oil is pretty "dirty". I can only assume there's a lot of crap lurking in the engine, and a good cleaning/flushing may be in order. (I see Amsoil and "Mighty" have flushing products)
I'd like to hear from you pro's out there re: good/bad idea? right/wrong way to do this?
Thanks for any help !

Run a quality oil and change it regularly. That's it.

I have been working on engines for 25 years, like the last post change your oil 3500 to 4000 miles and use a good filter, Your motor will stay spotless inside. Do not waste your money on flushes, they can do more harm than good under some circumstances.I have seen some additives that eat seals and gaskets, use a good oil and filter and change it often.

I think it is not needed, especially if you are using a good synthetic, but if I was concerned about it I think I would do the Seafoam and back to back oil change once every 10k miles or so rather then buy a purge kit.
