Home made expansion chamber exhaust - No welding

[mekano]

Hello all friends! I apologize for being away for a very long time, the reason has been drug related.
Anyway! Here's how I did my expansion chamber with an old Puch exhaust:

Pic 1: The Puch exhaust.
Pic 2: This is where I sawed it off.
Pic 3: Sawed of the original exhaust.
Pic 4: Put all pieces together and used heat resistant silicone tubing to hold it together.
Pic 5: Keeping the exhaust in place with ordinary 90 degrees iron thingies from the hardware store. It is mounted on the sadle pole nut, it was a perfect fit!

You can buy the exhaust online, here's one who sells it, mine was alot cheaper though... Try google if your interested in buying one:

Peace! /Mekano

I will get back with a report as soon as my handlebars are in place, waiting for converter to my 1" stem.
Meanwhile, doing some very discrete upgrades to the piston:
Pic 1: Before
Pic 2: After and in place

PEACE!

Hey Mekano,
Good to see you're back. The exhaust looks good. Is that the same bike you had before?

Hey SB!!!!!! Hope youre fine, read about your incidents and hope thats been fixed.
It sure is the same bike I had before, it is a 62cc that has been collecting dust for a looong time now.
Nice you recognized it!
