Honda CB500-4 Cafe Project from England Needing some Magic

This old 1972 inline four Originally came across the waters about 18 years ago now and has never run on this side of the pond, sat in storage for many years, this old girl needs a little pick me up to see if she indeed will ever run again, as no idea on the history of the bike much or if the motor is ok, but it has compression and a little bit of spark so on to at least a fighting chance.

The Carbs are a right mess and not surprised being sat for all them years and all gummed up like an old man with no teeth.

It needs two throttle cables as only one on there right now but can get new ones once I get this inline four fired up again, it is a great bike and look forward to later on in the month riding it, although the gas tank has 20 year old gas in it, so need to get that out and get rid of the toxic fumes that really stink, plus I do not want the tank to delaminate either.

Them old Gold Plastic tubes have no filters etc., so think I may get some Spun velocity Stacks or some Pod filters or bread box set up, but- the main thing is to see if this old girl will fire up, I did squirt some carb cleaner in the carbs and check for spark and she coughed a few times, but these carbs have got to be gone through and I am sure she will run.

If these carbs could only talk, I am sure many yarns would be heard and would love the history of this inline four machine as it was ridden well for quite some time back in England.

Carbs are off and they need some love, been sat for decades and never been run in that time at all, everything seems to function as well as the choke lever, so thats a good sign already.

They surely have had a hard life, but, nothing that I have not seen before in the 22 years of playing with these over here in California, and these will get a new lease of life for sure and be great to hear that old 4 cylinder Honda fire up again.

Now thats look a lot better right? These are cleaned, vapor blasted, rebuilt, new parts, polished, plated, ceramic coated and synchronized  and ready to go back on the bike.

So, at least we have a good chance of this running now and hopefully the motor is ok and will fire up after some persuading with a New battery and New fuel etc.

This is no show bike but the carbs had to be re built, so may as well go the extra mile right?

Lets get these Carbs back on the bike and see if we have a fighting chance of getting this bike fired up, I am sure it will smoke for sometime as no idea what’s up the exhaust pipe?

I got a small fuel leak from the bowls on first start up but all good now and just need two throttle cables for a snappier return but happy she fired, the exhaust I am sure will smoke for a while until it burns over 20 years of dust from inside it off, but hope you liked the video?
