I used the SEA FOAM and it was great. I have changed the oil twice since then and it is coming out clean and clear. Should I change it again or just fill it and run it with some sea foam additive in it. I am planning on filling it with fuel and adding the sea foam to that as well. I added the ISO to the fuel and it is no longer hesitating at take off and has great throttle reponse. Thanks to everyone that gave advice, I am thankfull that the people on this forum know what to try to keep our machines running.

Thanks
