It's essential that you open up and clean the centrifugal filter. I think the interval is 3000 miles. There is always a significant amount of deposits in there. When it reaches the top of the vanes, no more filtering takes place. I've seen many like that. I reckon around 10,000 miles to fill up. Bear in mind that the oil goes through the gearbox as well as the engine, so any gear wear will end up in there.

Video showing how it is done on the CG125. The bits of metal in that centrifugal filter at minute 6, look exactly like what I took out of my brand new cg125 in 1989. That had the same scraps that looked like leftover machining swarf. That was at 300 miles from new when its factory oil was drained and changed. It never had another bit of that after that initial run in oil change. I suspect that unless the clutch disintegrates scattering bits of friction material, that is the end of sizeable fragments until bearings start to break up. Note the size of the crank main bearing at minute 6. Hugely over engineered for a ten horsepower engine. I know someone who has ridden two of these bikes to 90k and 100k miles and never opened the cases. OIL CHANGE every thousand miles - mandatory for long life on these and also, not riding them full throttle all the time, which many young lads do. Of course they are not really suitable for an long trips on an A road where you need to run at 55 -60 all the time. They will do it, but it seems cruel and heartless to me. I did once ride one from Newcastle to Steeple Claydon in Bucks, and back, but that was at about 50 -55, so not too harsh.

This particular small push rod engine was Honda's approach to early failure in engines exported to south Asia where the normal practice was not to do maintenance until something went wrong. The OHC engines back in the 1960s were failing all over that market because of late oil changing. This engine is still being produced there now and exists in big numbers.

I serviced many different bikes (all Hondas) with centrifugal filters including several of my own. They always have that sediment in them. What you see in that video is typical of any 3000mile service. You can see that his one had been cleaned before, probably many times. You're a fool if you believe that it's only the initial manufacturing swarf. As I said before, I have seen many where every space for the sediment was full.

One could ride an outfit (any size engine) on a provisional licence, you did not need any passengers. I had a go on a mate's BSA A10 outfit once, I did not enjoy it.

When I was 17, I walked into the Swindon Motor Co. with a deposit and rode out on a gold Honda CB250K4. It had a top speed of 82MPH. No lessons, no CBT, nothing. 20 quid a month. It was like, "Here's the keys, off you go."

When I eventually took my test in Portsmouth, a bloke stood on a street corner and watched me go round the block a couple of times.

I loved that bike, I wish I had it now.

(not my picture)

Do you remember when the examiner jumped out in front of you for the emergency stop. He should have been paid danger money for that.

I do. I took my test on my dad's Honda c50 'cos my beloved Enfield 250GT had been stolen.
The c50 had quircky leading link front suspension meaning that, as you braked, the forks rose up and over the axle. Under heavy braking the front wheel would judder/skip down the road.
This is exactly what happened when the examiner jumped out in front of me. Brakes were applied and the c50 dutifully skipped down the road and the front wheel ended up between the examiners legs with the mudguard just short of giving him a John Wayne walk for the rest of his life !
I passed. In fact he praised my bike control.

My examiner in 1972 didn't jump in front of me but stayed on the pavement. He had already warned me that on my next circuit round the block that he would be waving his clipboard when I had to hit the brakes.

Exactly what happened to me and he had to wave me forward as I was further down the road to give me my next instruction.

With my car test at a junction with cars steaming past the examiner said to me "Get a move on your holding everybody up behind". I thought I can`t move out yet and ignored him. I'm sure he was trying to panic me. We were in a BSM dual control car and whether he would have done that in a private non dual control car I have no idea. Passed any way.

Cooler King is a UK company, but their bikes are themed on motorcycles and made in China. They appeal to me but I don’t think many on here share my enthusiasm for them.
I think one of the aesthetics issues is it looks mostly like a motorcycle, but appears to be missing a chunk of it. Which as y7ou say doesnt appeal to that many.

Personally I think they are fuking hideous, but i did take a look at the website.

They have this

IT's A FUKING SIDECAR !!

Sidecars are cool. Bike itself might look utter shite, but throw on that sidecar and it suddenly looks fantastic.

Right hand sidecars on motorcycles are illegal in UK. How does that work on 250w 15 mph ebikes?

My examiner jumped out between two parked cars and waved his clipboard at me. He did not actually get directly in front of the bike.

I remember I went directly from the test centre to the nearest motorbike shop and traded in my 250 for a 500.

I think the end of all these lax motorcycle laws came about when Yamaha introduced the RD250 twin. They could reach 100MPH with a fair wind.

The 250 max cc for learners law was originally designed for bikes like the BSA C11G which could manage about 45MPH so long as you had a two mile straight bit of road in front of you to eventually get there.

There used to be an old tale going around among us young motorcyclists in the 60s and 70s, that some mate of a mate had heard of a case where the examiner jumped out in front of an oncoming bike, but it was the wrong bike and the rider ran into the examiner....

Almost certainly an apocryphal tale, but we all heard someone tell it in my day.

My father-in-law is eighty eight & took his motorcycle test about seventy years ago. He tells me that when the examiner jumped out waving his clipboard he hit the brakes so hard they locked up & he fell off & failed. He subsequently passed a re-test.

My 1st examiner followed me in a land rover and directed me where he could not follow, I spent 1/2 the test sat by the side of the rd waiting for him to catch up, failed me for hesitating at a junction when afaik he was no where near??

Following month i retook the test and passed but had worn my glasses without realising the weak lenses had popped out (nhs john lennon frames).
At the end of the test and i discovered the no lens frames and laughed, the examiner looked relieved and said 'thank goodness i dont have to pass a nutter!!', the odd looks and side glances ever since i spent 2 minutes working the glasses on with the helmet on and squinting at the distant numberplate when asked to read it instantly made sense.

The local driving test centre was roughly 400yds from where my parent live, long gone I believe, it was in a small strip of shops with small car park for about 4 cars.

I needed glasses to read the board in school however never wore them apart from in class, we'd seen instructors a few times over the yrs doing the license plate read test at certain distance, it was either one in the small car park or one parked on the street near to test centre.

Day of my test there was one car in car park and only one parked on street so I memorised them both. Sure enough I was asked to read the one on the street...PASS! :)

My mum trumps this, she passed her test back in the 1970s and spent 20mins in a traffic jam on High St, drove less than a mile in total and passed!

My car test started with me reversing up the kerb on the way out of the test centre car park, In my mind i had failed automatically but the test didnt start until we left the centre apparently.. I lost all inhibition and at one point turning the corner to meet the back end of a bus pulling to a stop, I just dropped into 1st and sped around the slowing bus raising the examiners eyebrows as he turned and stared at me monitoring mirrors.. hell i had failed, might as well get some practice in..

My jaw hit the floor and stayed there when the word congratulations left the examiners lips...

My dad never had a test. He was a travelling salesman at the time; first company car collected in South London. They showed him the gears, and he drive it to North London.
