Except that the engine is painted, not bare or anodized alum. I would try some simple green, or a very mild degreasing agent (DP engine cleaner - not Ducati Perf.) that is safe on painted parts. I would also see if a soft toothbrush with just water would take it off.
This certainly makes sense. I live in a cold climate and only put 500 miles on before getting the Termi kit, and I had no trouble with the paint changing color.The reason being, because of emissions standards, the stock engines are set up to run lean, which in turn makes them run just a bit hotter than the paint can withstand. . . . The best way to avoid this is to change from the stock ECU as soon as you can so that it can be mapped to run at optimum.
Actually a BMW GS owner prides himself/herself with a dirty bike. Dirt shows that you have been riding.You sound like a BMW owner, no offense if your not but you act like one
I don't know who that was directed at, or what it means really. To each his own. I like to take care of my bikes and have a "showroom" clean bike. That doesn't mean you have to do the same. Please stay on topic.You sound like a BMW owner, no offense if your not but you act like one
I hope to put that many miles on my PS. It's heads have become so caked with baked on muk, I doubt it'll ever come off... Oh well, in a way, it adds character and comes with the turf when I ride in the rain as much as I do... I'm at 35K miles. I have a long way to go to match what you did with you K bike and I'm really looking forward to racking up those miles....Well, this one was still running, on the original block, no valve job: 280,000 miles. That can collect a bit of filth.
