unrestricting a sweet puch magnum 2

Erik Kovac (NJ) /

I finally go the magnum running and it does a sweet 28 but im conflicted.

I see so many people do cool things to the magnums but mine is so clean stock its not funny. is there a good way to derestrict the 1.5 horse power magnum? thanks

Re: unrestricting a sweet puch magnum 2

I'm fairly certain the only difference between the 1.5 and 2 hp are the intakes and head gasket size. 1.5 had thicker head gasket, 12 mm intake; 2 hp had thinner head gasket, 14 mm intake.

There are plenty of performance options that you can try that won't change the stock look (drill out carb/intake; port cylinder; remove head gasket for more compression). Search the forums. (edited)

great ideas! i will try to take off the head gasket. also, the pipe looks like it is restricted, does anyone know about this?

Re: unrestricting a sweet puch magnum 2

That's just a baffle in there. Leave it in or buy an exhaust like a biturbo, boss, or circuit pipe.

i know all about performance increasing parts, just wanted to know if someone on here knows about the restrictions on a magnum 2

You got to lose the stock pipe and get a performance pipe or chamber.

A two stroke needs a expandsion chamber

More in More out. Very simple designed "air pump"

i see, so generally speaking, the stock pipe is not restricted? I will remove the head gasket, it does look really thick, and then see how that changes things.

Re: unrestricting a sweet puch magnum 2

the stock pipe does restrict air flow.. from the pump (cylinder)

Buy a biturbo and call it a day. Remember to upjet! (edited)

Stock pipe sucks

Get a Estroil and bend it to fit your angle exhaust port

IF you want to keep the stock look of the bike, pull out the header pipe and drill four holes in the pipe, I am thinking 5/8" two up near the top and two near the bottom and replace. Get a 14mm carb and intake and upjet to 64-66, nylon over the air intake on the carb. Mine does about 33-35 with this setup.

Re: unrestricting a sweet puch magnum 2

Does anyone know if a Magnum pipe can be derestircted like the Maxi exhaust tutorial from the wiki?
