MOPED ARMY

Roffman. I appreciate the info.

Estorils are almost soldout everywhere so a lot people must be running them and hopefully can chime in too.

The old estorils don't have a restrictor in them, that's just something put out there by old heads who think anything but a straight through pipe is restricted.

The estroril's "restriction" really just gives you a great torque profile in the low-mids, which is EXACTLY where a mild setup needs it. Sure, this creates a bottleneck at hi rpms, but that's not a hindrance in most setups.

A normal estroil is restricted about 900-1,000 rpm, call it what you want but there is a hi rpm restrictor inside it making a lot of the rear cone useless and increasing stinger length as well as being welded in crooked many times blocking stinger making for even less power,

I hated to cut open the pipes, remove that thing then reweld, after half a dozen I was sick of it that’s why I hounded Benji at treats to have them made 8-9 years ago without that hacked in metal crap inside.

I’m glad he did!

Removing it/not having that thing in there does soften the lowend a little bit but it revs out like a pipe should and rear cone acts like it should/what it looks like from the outside, it is improved dramatically, it becomes about the best mass produced Puch performance pipe for the price

Wow. Can’t deny the pictures as proof. Good to know about the older style pipe. Which leads me to two questions.....

Are all the estroils Pipes made with out the restrictors now?

Still didn’t answer original question is the side bleed better then the non side bleed “original”?

The answer is that proma circuit is better than both.

It’s better if you’d like to lose rpm for both circuit and all types of estroil pipes rev higher, Proma powerband is like “wow this is great” as it’s pulling hard in the mid range, then when you’re expecting it to rev out some more it just quits

The side bleed with the adjustable end bleed is a versatile choice.

Yea the side bleed might be the choice for now then try the classic style when in stock.

Can you cap the end so it runs fully off the side bleed or maybe that would create to much heat and compression of fumes.

Got it then it comes with a few bolts that have holes like jets?

the estoril radical sidebleed is a great all around pipe, but i don't know if it's better than the techno estoril. I think it taps out around 9k. the chrome radical sidebleed is very high quality. the other has a coating that doesn't last more than a year. i've found the estoril to be great all thru the range on my airsal 65 bikes. it peters out on top and doesn't seem to over rev like an mlm cali, or dos botanas, so instead of going 47, you might get to 43 on an airsal for example. a cali or botanas takes a bit to get going on my mild kits, but once they hit 30 they take right off to over 45 with the right gearing, tuning, and clutch springs. so ultimately it really depends on what you are trying to do, but the radical sidebleed is a very versatile excellent pipe. the screws don't do a whole lot imo. I run the closed screw as it is quieter and feels like better low end. the 50 mph boys on the 40 bike ride i was on this weekend ran cranks pipes, with good number of techno estorils, a handful of mlm's and a only a few circuits, and i was the only estoril sidebleed. they can run hot, especially if you don't have a really good gasket seal, so you have to watch that. Detroit moped works has a great pipe review on their web page (edited)

have the classics on a couple bikes, lots of hills where i'm at i wouldn't use anything else

E50 low end is all about the clutch tune. Gotta get that stall up for the pipe to hit it's powerband.

I have the botanas pipe. It is a little beast for the price. Nice high rev pipe. My clutch slips until almost 30mph but once it grabs it takes off since the pipe is in it's powerband. My max has been 52 with 17\42 gearing.

What kit Jay?

Been looking at mild pipes for the new metrakit I have coming. Was looking hard at the estoril side bleed and after reading this thread, I think that's clinched it for me. (edited)
