bumper sticker available in black, blue or red. manual cleaning is indeed possible to achieve an acceptable result in a quick and efficient way. the faster you accept that, the easier/better. the source of all this trouble is no mystery. others require electrical or gas heat to operate. i changed the oil aswell, i don’t like it sitting in the engine for too long so some fresh 30w red line race oil gives me some piece of mind. but there is still nothing i’d rather hunt than a spring gobbler.
