True duals on a BRAT

Featured Replies

i just finished putting true dual glasspacks on my 78 brat, am i the only person to ever do this? ive searched and cant find anybody else that has! am i unique? am i insane? 

The kid I sold my 84 brat too dualed off with cherry bombs and exhaust came out in front of the rear tires .......totally loud

yes... my brat is also loud... but the old exhaust was rusted off and pointed at the gas tank so... yeah

that is actually a "feature" it keeps the gasoline from freezing in the winter...

 

The problem with true duals is it can make the engine abit "peaky" with no way to balance each side,so you loose a little bit of low end.If you add in a piece connecting the two sides then it tends to work better-IE X pipe or H pipe.

Okay, well thus far it seems to have just as much low end. But time will tell i suppose! The main issues i am having are carburetor issues, but i cant afford the $300 weber conversion. Lots of vacuum leaks on mine, one vacuum hose completely gone and i have no idea where it went. Has a little filter looking silver thing that a hose should go on, but no hose. I have a rubber stopper in it now

That may be a breather tube. In one side out the other. I did the same thing. Put a cap on it and oil shot up the tube connected to my carb. Filling my weber with a shite ton of oil:( that was a task !

BTW I wasn't there but from the videos you tore that mud pit a new one,and more importantly sounded the best.

Awesome Brat Pooparu. I am into first gen's. what a sweet ride yours is though. Who made Your bumper, and great hood lines also.

The brat used to be Bill's(the beast I drive),Bill did all the fab work.

My 81 brat has full deuls two glasspacks xover and two bike mufflers one on each side blows rings out both side when cold and loud but not to loud did not make any power diff but sounds cool
