engine flush?

[Anonymous]

I am about to change the oil on a GS 650 that has been sitting for about 6/7 years. Is there any reason why I should not use some sort of engine flush additive for the first change, run the bike for 10 minutes or whatever the stuff specifies and then drain it and refill it with real oil? I was thinking it might be good to clean the motor a bit. What do you all think?

Kerosene works wonders, maybe a pint or so, let it run 10-15 min.

CHange the oil, ride it for 1-2 hours and change it again Should be sufficient

If after changing the oil twice and it is staying black you could drop the oil pan and clean it off. You are supposed to do this once in a while as part of cleaning the oil pickup anyway.

I used to add transmission fluid on the first oil change when I bought a used vehicle. About at a 1 to 4 or 5 mix. Run it about 500 miles and then change again with straight oil.
Learned this from my high school shop teacher. He said the high detergent properties of transmission fluid would help clean gunk out of the engine.

That's what I would do. Maybe use some cheap oil for that first ride. Doubt that any engine manufacturer would recommend anything other than motor oil.
