Hello. I have just acquired an 84 and 85 200M. They have sat in a conex box for many years. The owner has had them both for a very long time and gave me great details on them both. He said both smoked when he pulled the motors and I can see scars on the pistons. He said the 85 has slight play in the crank rod and that I should not run it like that. He says the 84 has a trans that is neutral at the top and the 85 is neutral at the bottom.
I dont mind doing a case split but I'd rather not if necessary and my plan is to make one rider out of the two.
My questions are:
Is there any reason I should spit the cases on the 85 motor and replace the crank in addition to replacing the top end? My current plan is to simply replace the top end on the 84 and pit it in the 85 chassis. Also, other than the trans being different, are all other motor parts interchangeable between the 84 and 85? Thanks!
