Aligning engines

[Rosco86]

Just working on a new project that has had a different motor placed in it. Looking for ideas as to the bvest way to reposition an original type motor in it. All engine mounts have been removed from the front and it has an unusual rear mount using alloy plates slotted around the swingarm to suit another type motor.  Know about chain alignment but it also has a non standard rear wheel, but i can deal with that when it arises. More concerned  over height from frame and angle tilt on motor. Would be easier if it was a maico, bulty etc where there is ample examples, but I am having difficulty getting much info, pictures, knowledge around a 1972 KTM with the sachs 125 motor. Motor position is important as it uses an up- through the frame exhast pipe. Any thoughts gladly considered.

i'm probably only stating the obviuos Rosco, but i'd bolt as much as possible together,motor,carby,airbox,exhaust,seat,tank {are there any exhaust mounting brackets you can use?},and chock it in place with whatever works, wooden wedges or temperary brackets. instead of putting bolts through the motor, i would try and use long lengths of round bar at first as the front sprocket is usually at 90 degrees to the engine bolts. you can square the motor up in the frame by measureing from the round bar {if that makes sense}. with another round bar through the swingarm pivot, it will aid in thos crucial measurements.
oh, and have a cold beer and some patience on hand.

Swing arm pivot point to countershaft centre to centre distance is very important(closer the better) and that they are on the same height.Higher or lower will promote or reduce squat under power in the rear.Next is chain aliagnment, this must be straight.The rest isn't as important as these two things.
