I have removed head, muffler, valve cover and airbox in preparation for the new head - just to get familiar with the parts you referred to in your instructions, however you began your post with ... assuming you've removed .. cylinder liner .. is there a special tool to engage the liner, is it threaded at the top ? I have removed liners from 2-strokes in helis before, by jamming a piece of wooden tooth-pick between top of piston and edge of exhaust port on liner and heating outer cylinder with heat gun and then turning crank shaft to push liner out the top but the procedure here is obviously different !
Also, are you aware of a torque setting for the cap-screws which bolt the head to the crankcase - or is it just a case of 'as tight as you can'
Thanks again, I want to do this right !!
