Jeff plug photos attached, cylinders 1 - 4 l - r. James the boots all look good, I inspected them closely. Also the carbs balanced v easily...
The one thing that should make the idle high is the wax unit. Can you see whether the length of the unit is changing as it should from cold to...
Thanks Jeff I have taken the vacuum petcock out of the system before I started into the carbs, I had read that it can give grief. Given the need...
I'm not specifically familiar with the VF500, but my VTR1000 petcock has a vacuum shut-off so the fuel can't flow with the engine off. A small...
Rob are you suggesting that I might still have carb blockages? As I understand it I am probably getting the stumbles with 1/4 to 1/3 throttle,...
Thanks Jeff, the exterior is in great shape for a 1992 bike, gets better every time I wax it. There was the expected surface corrosion on some...
I've been working on my ST1100 carbs lately so have a little first hand knowledge here. I'd suggest the enrichener circuits might be clogged, on...
Well I did work my way through the various air circuits again yesterday and believe I have them all opened up clean now. I have reassembled the...
Thanks for the offer James, got that already. I was hoping that you could explain the various air inlets to me. [IMG][IMG]
A normal intake vacuum is about 10" Hg or 25 cm. 4 inches is very low and suggests that there's a big intake leak in there somewhere.
I'd say you probably need a new battery, Lord Vader. In my experience an ageing battery will start well when cold, but fail when hot.
14.2 volts is a normal voltage when the engine is running and thus charging the battery.
If the bike is running rich you might want to check the airbox and airfilter are clean and clear, I've seen plenty of photos of rodent nests in...
What an interesting thread. I blame my slightly older friend Andrew and his big sister. Andrew and I used to bicycle everywhere together, then he...
Thanks Grumpy. Yes floats have bendable aluminium tangs, and I was careful to orient the carbs so the floats were touching but not compressing the...
Thanks for the non VFR related diagnosis chaps. I think you're right that this is an air/fuel matter. The diaphragms are good, I can blow down...
Jeff I'm floundering around a bit here. My other bikes run great and I'm not really familiar with rich/lean symptoms. Maybe the bike is smellier...
Yes you're right about the conditions of test. Across the battery with ignition on I get 11.98V, 12.7V ignition off. Head and tail lights are...
A have another V4 Honda, an ST1100. Given that it has gear driven cams (plus a belt drive), I'm choosing to call it my VFR1100ST, but I digress......
