    Ok, the exhaust work is extremely impressive.

    I've repaired exaust pipe flanges on motorcycles with thick pants or thinner shirt clothes hanger wire depending on pipe size welded on then painted with a couple of coats of charcoal grill high temp paint then dried for a couple of days.

    He's building a disaster with the home made air filter. He needs to look at a complete air box that has all the structure inside. He's making a lawnmower type filter with that foam. That's how I make filters for my mower. I would NEVER do it for a motor cycle. The foam is much too porous and will let in grit that will bore out the cylinder,and kill the bearings, ect. I bet he won't even put motor oil on it or white grease to seal the edges. Also he put light machine oil on the rear axle that's supposed to get heavy axle grease, and didn't even check the wheel bearings. This is the kind of guy you should never buy a car, bike , or mower from because he does everything half – assed.

    Very nice metal work with the flange and the cover! My dad had the gift, I saw him straighten a Model A headlight bucket with a decent dent in it and make it look like new. Couldn't even tell where the dent was! Thank you for the great videos, I really enjoy them!

    Hi Mustie, I originate from the UK, I am now retired & living in Thailand. My background is in aero engineering but I was bitten by the motorcycle โ€˜bugโ€™ long ago. Until I moved to Bangkok, I spent my spare time restoring old motorcycles. It gives me so much pleasure to watch your videos. My main weakness was painting. I restored a 1955, 350 BSA & decided to have a go at painting it myself but I did have the fuel tank professionally painted. I used an engineering paint, made by a company called Blackfriars, but itโ€™s main drawback was a long drying time & white spirit as a thinner. I didnโ€™t have a spray booth – I got chucked out of the wifeโ€™s laundry shed for getting overspray on everything. I sprayed it outside on nice days. Trouble was it seemed to attract bugs. So many times I had to remove the paint & start over. After I sold it, the man who bought it sold it on but one day I got a phone call from the new owner. He told me that he had entered it into a concours exhibition & it won second prize. He said that the judges were impressed by the paint work because it didnโ€™t have that hard โ€˜glassyโ€™ look to it, which made it look as if it had itโ€™s original paint. Itโ€™s main let down point was the fuel tank that was black with silver panels on each side, the silver should have been chrome! He wanted to know what other parts were not original so that he could make it fully original for future shows.

    Just bought one of these, supposedly it runs but throttle is not working……..love watching you take this one a part…….may have to hit you up for information on where to get parts i.e. carb rebuild, etc.

    with any stuck valve its sensible to remove the cylinder head and check out the valve stem,,seat and guides for corrosion.Good time to fit new valve stem seals if it has them. 9 times out of 10 the valve seats spotty with rust,and the stem needs a good clean.Guides need a good look over and clean, Lap the valves in by hand and its away again.Check the play in the piston and check the lip at the top of the bore which is a good clue for blow by. Enjoy your videos,cheers Graeme from New Zealand
