1984 VF500F with 86 engine complete rebuild

Yes indeed.... heal up as the Capt said!

I'm nursing a broken rib, myself, so don't feel you're alone.

Stuff like this is what we call a reality check.......

 

RC … man!
Ok heal up and get back in the fight!

get well and get back to work

 

Hope you heal soon.

 

Well I'm BACK And have started work on my VF500 again. I'm having an electrical issue when I try to start it. I keep blowing the 10 amp fuse marked "Tail Meter" second fuse down on the left side of the fuse box. Does anybody know what this fuse controls ? They are not listed in the schematic. I've disconnected about everything I can that doesn't affect the run or starter. I even put a second battery connected just to the starter wire thinking it might be drawing too much current . Any ideas ?

 

Taillight and gauges, right?

That is an odd fuse to blow when hitting the starter button.

That's when it's happening, right? Not when you turn the key on?

 

That's right. Everything works when the key is on except the starter.
Something is drawing a lot of current through there. Also the lights are LED.

 

As this is far from a stock VF500, I think you're gonna just have to be very methodical (on your own).

Something isn't happy with how it was plugged in or configured.

 

Agreed Capt. I'll try to figure it out.
Thanks

 

Does anyone know of a replacement ignition switch for the vf500f ? Mine looks to be bad.

 

If you want to test the theory and see if it is responsible for other issues, disconnect it and on the harness side connect the correct wires for the "on" position according to the wiring diagram.

On the older VF/VFR it is usually RED & RED/BLK gives you full function.

 

Thanks Captain 8Os. I'll test it for other problems. I know the switch is bad because when I turn off the key it shorts and blows a fuse. I had to cycle it several times to find this out. I also noticed that turning it on also shorted it out occasionally before. Something is wrong inside the switch.

 

Using your method Capt I still couldn't get it running. I checked the timing and it was set to the T2 mark. Then I realized my engine was an 86. It should be on the T1 mark. Now I have to go into the cams and change their position.

 

I've seen them on Ebay.

 

I found a way to adjust the cams without touching the cam chain tensioner. They're set to T1 now.

 

I thought my cams were set but I've run into a problem adjusting the valves on the front right side exhaust. The cam lobe is pushing down on the valves. I've got the timing mark on the T1 and all other cams and valves can be adjusted fine. It's the correct cam F-ext in there. I've even tried rotating the cam 180 degrees on the sprocket. I can't figure this out. Maybe someone can give me an idea of whats going on.

 

Can you clarify this statement? Define "all other". You mean on one timing mark, "T1", all of the other valves are in position to be adjusted?

 

Yes it's weird. It's as if the FR exhaust lobe was in the wrong position. Everything else is fine and yes they are all on the T1 mark and ready to be adjusted.

 

R F lobe thats compressing the valves

L F cam lobes that are ok

 

Something is very not correct then. And, really, not possible. Or your description is very misleading.

I know when adjusting 86, when one (say cyl 4) intake cam lobes are at maximum lift, cyl 2 intakes lobes are opposite and in position to be adjusted. All valves can't be in a position to check at just one crank position. Pretty sure the (Official Honda!!) Service Manual doesn't even mention timing marks for adjusting an 86. Just check when one is at max lift, it's neighbor is not. They are super easy.

Are you working with a Factory Service Manual?
