Scooter carburetor comparison

[@tomjerry6529]

Nice to see youngsters understanding oldstyle technology! Keep on going!

[@ifrit35]

When I was into scooters 15 years ago PWK and Mikunis were the best way to make big power but notoriously hard to tune. Personally I had phbg from 17.5 to 21 and 19 was the sweet spot. The main jet was no big deal, somewhere around 92 or 95 most of the time and the needle had a big influence at half throttle like he mentioned in the video. So yeah, for a mild build 19 PHBG was my weapon of choice. Currently I have a 21 phbg from polini on my 50cc Pantera. The main jet is a 92 from factory which seems very small but actually performs great. I don't know why they went with a 21 for an engine that small. On 70cc Panteras they went with a 19 PHBG, go figure!

nice

Where do I buy that fitting?? For the Polini CP (Clamp fit) I have brought a cp and my manifold will not fit it's to bug for the one I have got. My carb is a polini CP 17.5mm

Hello, I have a 125cc scooter that has problem with carburetor the model is Piaggio super hexagon gtx 125 please suggest me any carburator

[@Scooterswapshop]

sorry we dont have those bikes here i suggest cleaning it

[@jamest.5001]

Is there any gains swapping to a slide style carb, for the 4stroke, gy6 China engines, over the CV carbs they use? Has anyone made decent power with these engines? Or are they the lada of scoots? I'm running a 50mm bore, ported head, with an A9 cam, (what ever that is worth, no real specs on any of the parts, compared to car parts!) But I have a free flow exhaust, ported intake matched to the head, I'm thinking about trying water methanol injection, I'm building another engine, with a 52mm bore over-size valve head,/with possible stroker crank, for about 95-96cc, I have a 24mm CV. Carb, and a modified nibi 150 intake, matched to the ported head! Im hoping for about 3x stock HP maybe more TQ, I am looking for somewhere to get it balanced, I want to lighten the flywheel/rotor, (everything rotating) I already swapped to a aluminum driven half for the starter gear/variator, about 1step above stock clutch Bell, nothing fancy, I'm mostly concerned with getting the heavier piston balanced with crank, I could potentially be spinning it to 10k-11k maybe more, with the titanium retainers and valve springs, it should easily do 11k (as far as the valve springs are concerned) I'm hoping for enough power to cruise at 40-45mph, with a top speed around 55-60, (with a tail wind, ) but mostly maintain a decent speed up hill, I have another China scoot, I'm going to 150swap, that's what I should have done with the other one, but I already have most of the parts! . and I need to keep it somewhat legal! (Don't tell anyone!) Sorry to ramble,

[@Scooterswapshop]

Paul and Brandon discuss alot in this video if you want to switch it up give the shop a call talk to Paul and he can square you away.

[@Merkh26]

Hey brother hope you’re doing well, I have a question that’s off topic. I have a Honda express2 scooter all original I’m looking to make a GY6 long case swap on it. My question is what would be right size wheel for it? I have 14 inch factory wheels and it would be nice to keep the original size wheels, but I’m concerned that I would need to buy a GY6B engine which can hold a bigger wheel but they’re over 500 dollars for them and I don’t want to spend that kind of money. Any help would be appreciated thanks in advance, stay safe out there.

Is the 21phbg too big for my 70cc sport setup on yamaha bws? It doesnt seem to get in tune especially in idle. And would you recommend 21mm or 19mm polini cp carb for airsal t6 racing cylinder which im going to get?

[@Kyrpis]

Nah 21phbg is fine for a 70cc sport setup. I had 21phbg with my 70cc malossi sport and it was easy to tune and the power output was good.

Good informative video. They could be a fair bit shorter(you mentioned it being a bit too long) if you guys just officially swapped places rather than continually allowing Paul to start explaining and then you jumping in and re explaining it all. Paul needs to point a camera at himself all day every day until he gets over his stageless fright. Unless he's like me and just thinks better than he speaks and has a hard time vocalizing thoughts accurately. That's a confidence issue usually and unfortunately not an easy fix. Age will help. I like Paul better if that matters. (No offense meant if you're not Paul. We can't all be Paul)
