I decided to have a go at a 86 VFR700 that has been garage parked for over a decade. Single owner machine, with 20k miles, original bodywork included, came with boxes of spares, etc. Found it on local craigslist; had to outbid a breaker who wanted to part it out, the PO (OO?) let it go for $800. Even if it never runs again I can use the parts on my 87 VFR. My first order of business was to clean out the cobwebs and rodent stuffing from various crevices. I didn't see any rodent marks on the wiring so hopefully the mice were transients and not permanent residents. I would like to check if the engine rotates freely. I've done orphan rescues for small offroad singles. With those I would apply penetrating fluid to piston via spark plug hole and rotate crankshaft by hand. What is best approach for a multi-cyl v4 ? Can I turn over engine by hand ?
