Hi
I'm a regular reader and contributor to "Basket cases" and "Show us your Twinshock" threads and I love to see the effort that goes into restoring an old bike,,, of any sort.
Whilst saying that I would like to see more of the 4 Stroke classics that are hiding in sheds, some that occasionally come out and also those that will never see the light of day again.
I know of a 350cc Matchless, an HT5 Ariel, a Gold star BSA, a Triumph 500cc twin, a couple of Royal Enfields which are all ready or nearly ready to go and numerous Cubs and BSA C15's which do see the light of day, and these are all within. 50 kms in SE Qld
Maybe if some of the owners were to see a bit more interest in these 4Stroke Classic oldies we might start to see a few more of them at the right type of event.
I don't want to cut across any of the excellent threads that are already up and running but if its a 4Stroke oldie, maybe even a basket case or should I say a "box of bits", lets see it on this new thread.
I'll start it off with a couple of mine which are Project Cub No 4 and my BSA "box of bits"
The Cubs come up twice, don't know why.
Come on guys lets see some of those golden Classic 4stroke Oldies, don't be shy it doesn't matter what they look like, anybody looking at this topic will love them.

Re: 4 Stroke Classics
Hi Everyone,
Great idea Roger, I for one would like to see more photos of old bikes in pieces or being ridden no matter how rough they Are! Classics are always a crowd pleaser at any Trial. I have to admit that my knowledge of 4 Stroke Classics could probably be balanced on an exhaust valve from a BSA Bantam?
Perhaps someone could identify this one that I spotted recently on the side of the Road?
Is it Olde enough to be eligible for Pre 65?
Is that an unusual Frame?
What would it have looked like coming out of the Showroom?
Are any of these Competing?
What is it actually Driving?
Yes I have more Questions!

Re: 4 Stroke Classics
Here is my British Classic 500cc 4 stroke single, rigid rear, girder fork Norton.
The photo was taken in about 1969 and the bike is a 1937 model.
It has a sidecar on it now but even as a solo, it's not remotely suitable for the sections we have nowadays, so I usually ride modern (1970s) trials bikes
As you can see in the "before" photos, it was such a basket case, it didn't even have the luxury of the pieces being in a basket

Re: 4 Stroke Classics
Hi Greg,
Think this maybe close to motor type.

Re: 4 Stroke Classics
Hey whitehillbilly I was going for an M21 before I got to your post, well done
Greg, I'm guessing by the amount of crap stuck around the motor that it was powering something to do with concreting, perhaps a pump or a finishing heli , whatever, it would be a great find and to see it end up with two wheels as well would be orgasmic.

Re: 4 Stroke Classics
Hi Everyone,
Roger, it sounds like Shane has got the motor right, at nearly 600 cc it might be a handful in the sections without even considering Gravity!
Good guess by the way, but everything secondhand used near concrete usually has concrete on it so no cigar for you!
Following Shane's link tells more about the motor and what it is designed to do may help you work out what it was driving.

Re: 4 Stroke Classics
I reckon Greg's BSA motor powered a saw bench
Before I was around, my Dad had a small dory called "Frothblower" powered by an old BSA motor that looked like that motor of Greg's but was probably smaller. One day he went out fishing in the dory on his own a fair way off the Gold Coast and he must have been giving it a bit of stick because he managed to bend a pushrod so much that it wouldn't run. Luckily he had something hard, flat and heavy in the boat and managed to straighten the pushrod enough to get back to shore again.
Many years later that same BSA motor was used to pump creek water when we went on gem fossicking trips in Northern NSW. It's probably still at my Mum's place

Re: 4 Stroke Classics
Hi Everyone,
"Frothblower"! There is a 4 Stroke Classic right there, perhaps it was named after alcohol had been Consumed?
Saw bench is close enough David, it is actually a Hargan Saw:
Probably from a time before Workcover?
Something tells me it was re powered at some stage so now for some more questions:
With the gearbox/kickstart removed how would they start It?
Would it have worked OK with the motor tilted forward almost 90 degrees?
I wonder where the rest of the bike Is?

Re: 4 Stroke Classics
I'm not sure that motor hasn't been there all its life. Back then BSA did sell engines for ag use,as did Norton.The side valve BSA M20/21 and Norton 16h/Big Four engines I have seen on other things, such as rotary tillers. That little oil tank seems to have a return side filter and flow control. The carb looks like a spring return job with the jet in the valve seat.This type of carb has no float chamber, is very old fashioned and crude.My Father has 3 Wade dragsaws from around 1920 with this type of carb. It relies on inlet depression to pull the valve open,as it opens the air rush pulls fuel from the jet.When the inlet stroke ends the spring pulls the valve shut and stops the fuel,(And on the 2 stroke Wade engine seals the crankcase to make the mixture get pushed up the transfer port.)
The frame looks like it can be set to go from vertical sawing to 45 degrees either way - hence the need for a non float type carb.
Interesting machine,doesn't look like it would be too bad to get going,those motors will run even when completely worn out,so it wouldn't need huge money to get it to run.

Re: 4 Stroke Classics
Here's a little Italian belonging to an HMCCQ member, modified from a Stornello roadie. Some would say it needs a more suitable seat. The owner sometimes turns up at trials events to watch.
