the h-bar that connects the header pipes togeather, what is its purpose
equilization of the exhaust pressure pulse
if i remember correctly
could be full of sh!t..... :dunno_white:
does it serve its purpose very well because i think thats the only bike i have seen with one of those
but what do i know, thats why im asking lol
No really. And just about every other twin has something similar.
yosh pipes in the early 90's had them for the I-4 oil cooled bikes.......
so I was wondering where my throttle was???
this late at night....that sounds like a loaded question...... :icon_twisted:
hehehehe
Its called a balajnce pipe.
They are designed to help exhaust scavenging. When placed in the correct position they will help low speed exhaust flow. Low down torque but may limit top end peak power.
As an exhaust pulse pases the balance pipe a slight vacuum is created in the balance pipe which helps to pull down the exhaust gases trapped in the other cylinders pipe.
They also help to quieten the exhaust by allowing the exhaust pulse to expand, hence disipating the sound wave alittle.
The also stiffen up the exhaust structure for less vibration.
