You have to tune so you could stay WOT basically forever because how could you back off if some truck is on your ass just because you’re overheating etc.

Someone behind you won’t know you just backed down/slow down unless you put on your brake light and your brake light needs to be nice and bright too Just some little red LED stuck to the seat because you removed your fender,

You have to tune for sustaining temperatures not well I got to back off or I can’t go up this hill, need to blast and put on the choke whatever.

I rode with people who had untuned, poorly lit or no brake light dangerous bikes you don’t realize the danger you are causing to yourself and other people,

You know I have too! Yes some of the clones work, MOST are crap, but some work, and yes you can save some cash, BUT my real argument against them?

It’s supporting china crap at the expense of real manufacturers and sellers, this is how we lose quality in real products, if you don’t support them they’ll go away. Same goes for the sellers, do you want DOS or Treats to get the money and use it to keep in business/use the funds to invest in cool new products!? Or would you rather some china seller who subsists on child labor to profit? Support the companies and businesses that keep us riding, not the cloners

So yesterday I had the carb off to fiddle with the jetting and the damn thing wouldn't start. F@#king clones! But it was actually no spark as the condenser had failed. The quality of the replacement condensers are spotty. I just had to change one in my Florida Safari. It was new for the rebuild.

I previously had to change the jetting after I discovered the original coil was weak on this. I'll bounce the main back up till it four strokes again and then drop it back. Yes, sustained WOT would be fun but on local roads 40 or so is plenty, not 50+.

Andy, I now understand your dislike. I have bought more SHA clones from Treatland so I am for the most part supporting them and the others. I wish their quality of condensers was better though...

Ken, I appreciate your concerns. When I backed off it was down to 40 or so and the temps recovered quickly. I was already exceeding the speed limit. No vehicles tailgaiting. I also have a bright tail and stop light.

I'm still learning how to tune and know better than to ask for advice on tuning clones here. I was surprised the weak coil and now marginal condenser affected the jetting. Maybe these numbers will help others.

Thanks all.

I hear ya Andy, but I also think it's kinda bullshit that dellorto is still selling the same shitty carb after 50+ years with the wrong tuning parts in it for a hundred bucks. I buy genuine mikunis but dropping a hundred plus bucks on a phbg, then having to spend another 20 or more to get it to work right, and the quality is still crap.

I have been buying the same 19 phbg spigot KTM/cobra carb from a China seller on AliExpress, comes with all the right tuning parts, quality is as good as og, and it's like 20 bucks.

To be honest, I buy most of my carbs used, they don't really wear out and you can get them for 50 or 60 bucks with already most of the right shit in them. Just bought a polini CP, now that's a nice carb, better design, great quality, quick change jets, etc... That seems like it's actually worth buying. In my work, if you don't innovate you get cloned by China and you're out of business.

The included jets in clones are crap, but you gotta change em anyway. Put them side by side with a polini jet and even with the naked eye you can see the taper is different(which effects flow and atomization) and if measured with a wire gauge they are never exactly the same size as a same numbered "real" jet. I bet they use standard micro drill bits since the size is always 1/2-1 full jet off when I measure. Since PHBG19 is the stock carb for the popular KTM 50SX they can be found very cheap since its used so much, making it a great value.

Just like any clone inspect it first for burrs in the passages/machining issues (it is a Chinese clone after all) then throw in some polini jets and swap the needle if you got a wonky one and you're good to go. Its not as finicky with the needle choice as an OKO is since it uses a slide cutaway.

Plenty of carb for 60+ mph - my A35 BMX build did 63 with one with a 45mm Alukit and supporting mods.

That is a more then fair counter argument, I too have mostly switched from PHBG's to Polini CP carbs, I recently bought the 103 PHBG full set up, they switched the thread on caps from metal to plastic, it barely touched my frame on a bump and broke into a ton of pieces, I had to steal one off an old bike, then order a 20$ replacement. So I guess we both have pro's to our views, I guess the real moral of the story is buy a CP

The necessary up jet after correcting the marginal coil, then condenser is killing me. I'll get it. Those Polini CP carbs look like they're worth it. at least I can use my SHA jets for now...

Nice!

I got another clone 19 on its way by slow boat. This will be my 4th one, I'll let you know if it's 4/4!

The atomizer and needle on the one I buy isn't marked, I found a au272 and w9 that I bought (planning to swap into the clone) that I never used so if I get time I'll measure and take some pics to see if it's close or what.

Either way, it works great for me. This one is going on a pw50.
