Cleaning Top End??

ya i still have the stupid autolube oil pump on my blaster, and adding the seafoam worked out great for it, didnt harm it at all, i still had to remove my exhaust pipes and clean them by hand i just poured a bunch of that sea foam in both pipes let them sit for 30 mins, and then took a wire brush to get the rest of it out, i also did use a low flame blow torch to burn some of it off, but it worked great, pipes all basicly brand new, except still gotta repaint them(had to anyway before) with the high temp paint make them look all shiny lol, but ya if you do what the guy above me said you will be fine, if your still worried go to a performance shop and ask...they can definnetly help you out
 
Seafoam is awsome stuff, I've used it for years. I just mix it in the gas every other time, I mix 5 Gal. at a time. But I use it in my cars and lawn care stuff. If your weed wacker won't idle one tank with this stuff and it's like new. Great stuff and if you mix it with your premix or are still running oil injection you wont have any problems. Read the can the stuff can go anywhere, trans, oil, diffs and gas so it must be safe on the seals.
 
the best way to clean the header is to take it off, put like the end of a screw driver in 1 side and jam it up so as it doesn fall out, then there is some stuff you use for cleanin, cant mind the name but its something soda, its really strong acid. Pour it into the still open side and fill it up to the very top and then plug the other side, then let it sit overnight and watch your hands because this stuff burns.
