i decided to polish my end can as well as it had some considerably deep scratches i managed to sand out

do not like this end can that came with the bike i think it might be a bit to big. might mod it or put a smaller one on

to clean the inside of the pipes i removed the end can. tipped washing powder into the pipes and my old steering bearings i had replaced. then filled with boiling water after plugging the ends of the pipes and just shook it around for twenty minutes . 
turned out satisfactory thought i would share

have a good one  :thumb:

thanks for sharing. I was trying to use HCl as this should not harm stainless steel pipes. It didn't but also didn't remove almost any patina. I was afraid of making unremovable scratches from it by using sandpaper so I avoided it.

Good to know that it won't harm them.

the sanding removed the patina but was prep work for the final polish. i think if i had of just been intending to sand the pipes without polishing i would of taken it to 1500 grit. 
i have always been told autosol is good?. But have not tried it yet

That looks great!

Autosol is good, I have a tube that I use on the bike, but it isn't going to make the header look like that though.

I know because I gave it a go
