Hey guys been to a bike/Chinese bike Specialist today was out and found a shop on my travels, he had a whole bunch of chinese bike's with the same setup engine (CG UPRIGHT) he rekons there made in suzuki's garage in china and come with Suzuki support and parts warranty.
I'm talking about Kymco's and the new apachi 125 he had in stock.
Anyway i'm pretty sure now the engine is a 150cc it pulled too quick for a 125 and on measuring the carb it's 28mm pretty big for a 125 Chinese bike the one's in the shop on the 125's were tiny in comparison to mine.
Anyway in the process of blocking off the SAI (Emissions Valves) and trying to sort out a carb rubber (Inlet manifold) as mine has split and useless.. Struggling to find anything to match up with the engine side where it screws in gonna pop down to the bike shop tomorrow see what he has in there

1/ If its push rod, it will be CG copy, if its OHC its likely Suzuki 'copy'
Pretty sure yours has OHC Cam bosses in the ends of the head, hence OHC Suzuki derived rather than CG.....
2/ CCM dont offer a '150'cc bike...... you have gone through the possibilities of it being a '250 MX' motor, dismissed by fact its not a two stroke, to notion its a 250ccm trail bike lump... dismissed by the fact they dont make a 250 trail bike.... suggesting its a 230.... or a 125, and by engine cases more likely a 125..... of course it may not be a CCM engine... might just have aquired CCM covers.... could be almost anything, really.
3/ whether its a Suzuki or Honda copy engine, whether its a CCM badged lump, or any other badged chinese copy motor, with CCM cases attached.... the ACTUAL cc will normally be cast on the back or side of the barrel......
Meanwhile, in ALL probability, and on balence of probability, there are lots of engines it MIGHT be, but looking at the most likely ones for it to actually be...... far more likely to be a 125, simply becouse thats what there are most of knocking around!
As for the carburettor size, err, 28mm? Nope thats not very big..... the CG125 10bhp 'ecconomy tuned' 'pushrod' engine uses a single 26mm carb, so a slightly more powerful OHC Suzuki engine, likely to use a bigger one. CB125 uses TWO 26mm carbs..... one for each 62cc cylinder!
You keep looking for clues to suggest its more than a 125, kid... but you aren't finding any! LOOK AT THE BARREL!
If its been ground off, or isn't there, then its down to bore and stroke..... meanwhile, suggestion is its most likely to be a 125.
As for how well it 'pulls' and the way it wants to lift the front wheel..... its a dirt bike, and its one derived from a 50cc machine, it's light, its short and its top heavy, with geometry and balence designed to aid lifting the front end on soft surfaces and over obsticles..... this tells you nothing..... GEARING accounts for how it 'pulls', and low gearing can make bikes tug really really hard, and again, dirt bikes have low gearing!
Meanwhile it probably DOES tug like a 125.... even with a four stroke, air colled OHC Suzuki copy engine it it.... tug you'd feel at the bars would only be that of a 17bhp 250 four stroke single... barely any more than a learner legal CBR125 four stroke single.... a long way off an unrestricted DT's 20 or so bhp two stroke motor, or a full on 125MX motor with around 30bhp....... in FACT the 'tug' from an 80cc two stroke like a DT80, a big bore 'moped' with about 8 or 9bhp would probably not feel much different, given the way that two strokes in a higher state of tune, come 'on' the power band, the 'tug' you feel at the bars being amplified not by the fact they have a lot of power, but coming on the pipe, the power ramps up from bugger all to a bit more than bugger all very quickly.....
Power, and power delivery are VERY deceptive, and without either sticking it on a dyno, or running it to top speed under load, very hard to say how much it has.... EVEN if the power an engine makes was as closely related to engine displacement as to be noticeable between a 125 and 150 barel on the same engine!

10/10 for inginuity..... however, using brillo pads as filter mesh, you may as well not bother, for what it'll actually trap.
Sizing is also err, small.
Using a 'panel' filter, ie sheet of open cell foam, rough reckoner would be that the diameter of the filter element, should be as many cm as the engines cc displacement.
So, if you have a 125cc engine you want a circle of foam 125cc accross, or about 12,500cm2 thats the 'element' area, so if you folded that round or pleated it up to make a cone filter, you have an idea of how small you can make it.
Varies for filter material, of course; smaller 'screen' material, traditional tissue paper has very fine mesh, so creates a high resistance to flow, so to lower the pressure difference accross the element and retain flow capacity, you need to increase the element area. the 'metal gause' they used to use in the front of Amal Bellmouths on old Cafe Racers and lawn mowers, obviousely has a much bigger screen size.... filters bugger all.... stops rodents and small children getting sucked in, that kind of thing, but does very little to stop shit and muck...... area of holes to area of wire means that they can get away with it litterally being no bigger than the head of the bellmouth, maybe 1/2" larger than the carb choke size and see little or no pressure drop.
Filters are best housed in an 'air box' to put a big space of still air around the end of the intake tract to reduce terbulabce, and again, lower pressure difference accross filter screen.
And as a rough reckoner, again, variable, but that airbox ought to be about five times cylinder displacement ion volume....
Your 'scrubber' is pretty neat, and imaginative, and reminds me rather of the 'oil bath' air filter on old Landrovers, which used a similar filter arrangement.... but only in being beer can shaped and full of wire wool!
LR Oil bath filter on, INCREDIBLY under powered, 2.3l engine (Made about 65bhp, barlely what you get out of a 1275 mini engine! Hence similar air flow requirement) cylinder was about two foot deep, and about 9" in diameter.... the top of the cylinder had vents in it to about 1/3 of its height to let the air in, and it was filled with wire wool and gauze. a metal pipe in the lid extended to about 2/3 the depth of the tube, and connected via flex hose to the carb, and the cylinder was filled to about 1/5 its height with old engine oil....
Principle was that the old engine oil sloshed about and 'wet' the metal gauze to trap dust and crud as it flowed with the air through the gauze, sucked through from the carb......
Horendousely heavy, and restrictive, and not particularly wonderful at filtering finer partuculates, and sucking the odd bit of old engine oil, you would, sometimes burn some of it, and start fretting whether your valve guides or rings were about to go!
But you are on the right track... ish.
If you were to use the beer can as a termination to your carburettor snorkle, sealed to the hose, punch holes in it, and wrap filter foam around the outside, to get the area of the cylindrical sides as your filter interface, and then stick that into a larger cylinder still, maybe a 3l coke bottle or something.... you'd get better filtration and better air flow.

Looks 125cc to me, might be a 125cc engine bored out to 150? a sort of mate of mine did that to his field/dirt bike. 150 two stroke. Was bloody stupid, quick, 125mph apparently. But just stupid.
going back to your previous arguments, Mike, a few people down my area would shell out 1K for a 250cc learner illegal dirt bike thats built well, but with shite parts. ( not saying your parts are shite, but they are chinease)
16 year old near me spent £2K on an Rs50 and crashed it 3 times in 6 months..... made me and a friend chuckle as we both go with the 80's 4 stroke hondas. Youd be amazed at what kids do to look cool. Look at all the 17 year olds spending 3K on insurance and driving like f*cking idiots.
Ps. Love the rockstar recovery idea... might do it to my cb125... lol
