I 've a small problem with the right side pipe in my ultra , just a small surface part is near yellowcolour, i 'can't know if isburned or rubber or plastic or something else. It seems burned but can be sure 100%..
Any one knowsany product try to clean itbutwith no agresive product??
First, make sure you're not running too lean....maybe that's what is turning the pipe yellow (?). Second, S100 makes a product that is great for cleaning off any dullness, yellowing, etc. Check there websight, or visit the local stealer
