Cylinder Aluminium
Posted on Tuesday, July 21st, 2009 at 2:12 pmAny ideas on how to seal an exhaust on a 2 stroke dirt bike?
I have a 1991 Husqvarna CR 125 (2 stroke) in need of a little TLC.
Yesterday i removed the exhaust system as it sounded terrible, soon as it came off it was obvious why it sounded so bad, the tail pipe wasn't connected to the bellow part and the bellow was held to the cylinder/exhaust port with only one spring ( which was the wrong type and WAY too big)
So after potchin with it i managed to fit a makeshift seal from an o-ring out of some UPVC piping for the cylinder end connection and some nice new springs to hold it in place, and sealed the tail pipe to it with aluminium tape stuff i found in the shed which suprisingly has help up perfectly!
Its sounding better today and the power difference is tremendous! but it still doesnt sound right, my question is, would it be ok to apply an exhaust sealant like gun-gum to both the connections to make an airtight seal ? or does anyone know another effective method?
Thanks in advance
They make a tape especially for this application, I think it is called moto seal. Check the ads in the back of a dirtbike magazine, or your local dealer.
