With the exception of going back to standard bolted honda pipes, you'll never stop the splooge. At best you'll reduce or control it. Aside from running different oil or leaner ratios (careful), you could perhaps wrap a rag around the pipes at the head, changing the rag after every ride.

I think every two stroke owner has accepted the splooge as inevitable. I did try sealing my tyga pipes twice with the high temp orange rtv crap. It didn't help. Despite cleaning the surfaces, applying liberal amounts and waiting 72+ hours. Next time I'll try high temp silicone. Had success with it on four strokes, maybe it's worth a shot? I'll try it next time I need to take the pipes off.

I've heard that there is a chance of reducing the splooge by machining a groove in the pipe and installing a vitron oring. It may help but I doubt it will stop it. I've never seen a two stroke exhaust held on by springs that doesn't dribble sh*t.

Just installed a fresh oring AND sealed a ktm sprung chamber with silicone. If that reduces it I will let you know.

Don't waste your time on the orange sh*t. It doesn't seal. Too much movement in a sprung chamber. That said, the orange sh*t does not even seal my tiger silencers properly (and there isn't any movement there).
