If you search you will find threads on this forum that has used this kit. There are threads about how to remove the irritating hard sitting oil seal for the shaft. I'll use a tap next time that fit exact and can drag it out. A tip I saw.
I have used 2 kits. Oil strainer also recommended. Honda original available.
Forum member MessnerMoto has made new rotors, a little bit tighter to ensure oil pressure when engine is very hot. Both my oil pump restores got those too.
I did the pumps with bike on side stand, a wooden plank under to make it stabdin alnost straight.
Removed exhaust 3-4, pan off.
Laying on my back tp see the 3 bolts to remove pump.
Trickier back on, very easy to damage the small pipes that look like knock pins if pump is not exactly parallel with case when takibg it off and on. I learned to have extra home.
Make sure to prime pump with oil and let all air out before assembly.
Update: I had to drain pump in a deep oil bath, releasing the nut on relief valve letting bubbles out. I opened the other 2 bolts keeping the leak stopper valve to vent out a little air too. Made sure that oil could flow in. Pump could now suck better when my thumb blocked one of the 2 holes for oil lines and rotating the sprocket. Same on the other hole rotating in the other direction.
Conclusion: Only drain pump in oil and rotate the sprocket is not enough to get all air out.
"Start" with starter without plugs so it will spin quick to get pressure lamp going off asap.
