I used the digital camera to record the new exhaust on the '85 Brat. I had a real nice tuned system made for it. It consists of 26" header pipes @1.75" into a collector @2.125" which goes into 2.25" pipe through a magnaflow muffler and chrome tip. My master mechanic and overseer says that it is an absolute work of art. Take a listen and let me know what you think.

BTW, the first one is at idle and no, the new engine doesn't have a miss. That is the cam loping.

man too bad all the comps here at work don't have soundcards (unless someone wants to call me and play the clip for me :grin: ) but that will be nice to see at the rallyX's and Ken I agree with the gearing in the 4 speeds (imagine hearing my motor either screaming it's heads off in 1st or bogging in 2nd on the course around corners, darn 57hp :grin: )

Cam lope=lopey idle=a lot of cam overlap, causing gas reversion at low engine speeds. Both valves are open a longer than stock amount of time. You've got exhaust gasses mixing with fresh fuel charge, maybe some exhaust making it up into the intake, and some unburned fuel going out the exhaust. This equals a lumpy idle. "Why do this?" you ask. Well, it can equal a lot of horsepower at higher engine speeds.

You know all the noise a big horsepower v-8 makes at idle? That lumpy nasty sound? Followed by a defiant roar when the throttle is mashed? Same thing, little motor.
