Exhuast leak

MattCA · 02-19-2008, 01:48 PM

I noticed that the exhuast leaks from the header connected to the engine and the gasket between the header and silencer. Where can I find these gaskets? Its a 2001 cr125 with a pro circuit pipe.

the only leak you need to fix is the one from the expansion chamber to the head (i believe) the leak from the silencer and header should not be a problem

Well I would like to replace both because a sparys oil everywhere. I might be running a little rich too. 32 to 1.

MattCA · 02-19-2008, 02:11 PM

Nvm found it. I hope.

32 to 1 is the recomended mixture fir 125s, if you are in a race mix it like 50 to 1 and it will run faster, but your paiston will wear out faster

Actually, if you just put 50:1 in the bike that is suggested to run at 32:1 it will actually be running richer which means less power. This is real, you would have to rejet.

gscx · 02-19-2008, 09:21 PM

no, have you ever run a 2 stroke with out oil, it runs fast as hell because the oil isnt there to put resistance on the walls

gscx · 02-19-2008, 09:22 PM

it runs for like a minute though

tigmaster · 02-19-2008, 09:28 PM

Except for the whole fact that you are effectively doubling the gas in the oil/fuel mixture. That is why the mixture is richer, that is why you have to rejet. People do run 50:1 but you have to rejet. And if your only concern was friction, switch to synthetic and don't just switch to 50:1 without a rejet or it was all a waste. I have owned 2 strokes and 4 strokes, so yes I know what is best.

tigmaster you know I love you but, in all 2ts around here nothing but 32:1 is ran, no troubles at all, its what i recommend and what I stand by.
