Of course you vcould be extra ordinarially lucky and the orange sh*t will work. Buy a lotto ticket instead. You'll be less frustrated at the end of the day and won't be peeling skanky orange spooge off your hands.

Seriously, the orange crap doesn't work. I tried it on unworn, new (not refreshed) cylinders, chambers and springs. Twice. I even had it leak on the end cans which are held very securely to the pipes by three bolts (not much movement there). Splooge is something we have to live with. Not entirely skeptical or cynical so I will say I'll give something that isn't orange a try but only if I had to take the pipes off for other reasons. Hell, even my new ktm with 1,000 kms on it has splooge around the chamber - and that's been fitted at the factory!
