I am swapping engines. I am putting my '89 ported engine into my '87. I have the injectors and intake problems already dealt with....it's nice having the '87 engine still around. I am wondering how I will deal with the difference in oil metering pumps. The '89 has an electric and the '87 uses a mechanical. Does anyone have and experience in swapping them? If so, what pitfalls or hurdles should I be aware of?

Do I just disable it and premix?<hope to avoid this> All answers are welcome.

Thanks,

SpeedRacer

Different AFM's I assume.

Yep, swap front covers.

Or run premix like me

Thanks guys. :-) I will change front covers then.

FYI
VDI and AFM's were the intake woes. I will run the '87 intake to get it running and debugged, then I will swap to the '89 with the VDI wire open with the '87 AFM.

Don't wire it open, you loose the whole benifit of the VDI if you wire it open.

Go get a RPM sense switch and do it right.
