Seems very odd, and I've only just noticed, but motor looks to be about 1/4" 'out' over to the left hand side, while ridden.......carb tops too ( although I guess that COULD be wrong order of intake boots??) I've measured the engine in the frame,( tape measure, not EXACT) and it STILL seems 'off' to frame spars......maybe by about 1/4" front/to back, like it's twisted, back seems LESS 'out of line', frame bolts, engine bolts, engine/frame large rear spacer all present and correct, and tight .......should i loosen everything and see what happens? Bike runs straight and true.....well, maybe pulls to the left a little ( camber, i think would count for this??) But you can take your hands off the bars at 90MPH, and part form a slight tendency to wander left......there are NO wobbles, no uneven tire wear....apart from usual 'camber' wear.......should i be concerned, overly concerned or just ride the thing, lol !!.....>Guess i should check F/R wheels for alignment, yes?? No, I have never had the motor out, and even if I had, i've had these motors out many a time, never (to my knowledge) 'twisted' one!!!
