Does anyone make a PHBG intake to fit the Puch Polini kit w/ stock reed setup? I sure can't find one. I think the Peugeot PHGB intake might work But Id have to hack off some fins for sure, Because it mounts forward. I know I could get the upgrade PHBG reed block. But Its a brand new kit and I think Id rather break it in before I Blow it up w/a 4 reed setup. I dont see the point in paying for a SHA carb when I will just eventually upgrade and have to buy a PHGB too. And I aint running no dinky 12 Bing Blahhh. I might just make one my self. Unless there is a reason why these intakes dont exist. I could fab one up pretty quick. But , I have too many projects already.

Dallas of the Bropeds has a 16PHBG on his stock Polini intake, but the intake has been modified, naturally.

Yeah I thought of that too. That was my first idea. Drill it slightly to 16 And slap a shim in there. But I want to go 19mm And its just not possible to oversize the stock intake to 19mm. 16 sure 19 nope.

I mean the Phbg mount is 24mm vs 19 for SHA. So Id have to shim the stock intake to accept a PHBG. The max I could bore the stock intake is 16 maybe 17. So If I went any bigger than 16 W/ the carb Id just be restricting it.

Why doesn't anyone sell that sort of intake?

if you have the skillz to do all this why not just bore your stock bing out to 16 and rock that for awhile? polinii+2 petal+16bing is a great combo. 19 is quite a bit to flow on a 2 petal reed.

Yeah I guess the one thing I overlooked was going up to 16 on the bing. I already bored it out once to 1/2".

When I had it apart the first time. The biggest bit I had at my house was 1/2" & I didnt want to go to the shop. I just figure eventually I will want a larger carb and Id rather not pay for a 16mm and then pay again to upgrade. Yeh, good idea.

bore it out to 5/8" either with a drill bit very carefully or with a reamer if you can get one. should be a good setup, you might like it enough that you wont even want to go PHBG.

Looking at this Bing it seems that I already bored it to be flush with top of the jet holder 13mm. + or - So if I go any further it will either have a large decrease in size in the middle(if I just do both sides). Or I could go all the way through which doesn't seem like a wise idea. As then I would take off the top of the jet holder & the slide wouldn't sit on a flat surface there would be a large half moon shape under it . What would be the better way to go here? Sorry if I sound like a dummy but I a professional welder not bike mechanic.

But I now Im dreaming of intakes. So I guess Ill have to make one. I have allot of work left to do on this project anyway. Cleaning and painting & allot of engine work. I shouldn't even worry about all this yet. I have to finish my buddy's Newport first. Whatever, The never ending story..
