    Best stuff to degrease engine in frame

    Not having much luck with the search. Whats the best stuff and method to degrease my 1150 engine in the frame outside of the stinky gunk ? Its on the lift for a rear tire and black exhaust cleaning right now and its a good time to get to the front with the exhaust off. Ive used Simple Green before, just wondering if theres anything better. This is one of those bikes you wish yould never bought but its mine now so Ill rescue it. I bought it because its so rare to see one for sale out in Montana, its cruiser country here

      Simple green and a part washer brush is what i do. Tooth brushes for the tighter spots. Things like purple power and greased lightning have discolored aluminum on me so i stay away from them

      If youre gonna repaint it use whatever you choose.

      I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

        Use Gunk, but get the citrus flavor. It doesn't stink, much. Simple Green and the like don't work half as well.

          I used mineral spirits in a spray bottle, applied liberally, let soak and power washed. The bike was so oily, it did a good job of preserving the motor. Tight area's need a parts brush and a tooth brush where space calls for it. Turned out great

            Suzuki also makes a foaming engine degreaser. Ive used that and it did a fairly good job with some scrubbing. But I can mix up a lot more simple green for way less. I get the concentrate and mix up a bottle full at a time..50/50 mix.

              When I can get my hands on some of it, I find Traffic Film Remover is great for general degreasing. It's designed to be used in a feed to the power washer, or can be applied direct, soaked in and power-washed / hosed off. Applying it neat is expensive, and tends to leave streak marks on naked aluminium.
              The best of the lot is TFR and a steam cleaner. That'll take paint off, if applied carelessly though.
