First of all, it's 89 and up, 88 is the same as yours. Anything can be done, how much work do you want to put into it? The cylinder will bolt right up to the cases if you leave the power valve out, which leads to your first problem, the 89 and up have 3 shafts for the KIPS yours has 2, and of course the cases are different, there is more meat on the 89 and up case for the 3rd valve shaft. I think you could have the case built up or maybe even use devcon and build the area up, then drill for the 3rd shaft. I don't think the area would have much stress against it and would really only require strength to support part of the valve. The second issue is the KIPS actuation arm that would have to be replaced, the newer units have a smaller KIPS drum, no deal there you could just buy the arm. and lastly the motor mount on the back of the head may be different, I say different because the head stay is much shorter on the pre 89 units, but the head is also much larger on the pre 89 units. Did I mention that you would need to change the head as well as the cylinder? you will.
Good luck let us know what you do, BTW why do you want to put on a newer cylinder? I think the pre 89 have a better port layout.
