CB125t: 2-into-1 exhaust

[dangerous]

You would have fucked it regardless because you're so hard on gear, if you spent less time polishing and more time maintaining them it might be different

well actually... I pull the heads off the strokers every 2 meet and remove the barrels every 4 meets to be sure all is well... farked if I know what went wrong in Grey, best I can see is a jet blocked.

Rider abuse coupled with mechanical incompetence would be my guess

yours (was mine) is CDI the earler bikes were points so apart from tearing the fly wheel out and making it a toatle loss... I wouldnt bother, as soon as you look at taking it out more you will loose relibality, I have the specs for the 28hp engine but they dont last long and this engine is what the 2-2 is designed for so proberly not as eficent as whats on it.

Now can you post up the header length and diameter, length of cone and dia at the header and were it maxs out, the reverse cone you will have to shine a tourch up the pipe and take a guess as the muffler hides it.

I'll have a measure up and post ASAP

I know it's been a while but....
I've made up a 2 pipe muffler that has increased midrange power quite a bit, no dyno to verify this but lap times say it all. For that reason, I wouldn't muck about with a 2 into 1 of the dimensions from Dangerous' old CB because it's not as good as the 2 through pipe.
