Looks and sounds good! You may want to check with the tech folks
about the "open" primary, they may want the holes covered to pre-
vent anything getting caught in the spinny bits.
Cheers, Dave
Yes, I understand and acknowledge that. My plan is to get some "perforated" sheet metal, cut and form it to the inside, paint it to match the tank, and then epoxy it into place with 3M automotive epoxy. I'm now trying to get it dialed in and tuned, and then I will go back and finish off the odd bits and pieces.
1 3/8" primaries
Why?
Well, because that's the size that fits into exhaust port!
Bear in mind, I essentially have two 350 cylinders with a 71mm bore firing on opposite strokes. It's not like I have big block Chevy trying to pump out 50+ ci of air per hole. Besides, changing to the 2" collector has already opened up the exhaust so much over stock, I no longer have much bottom end. Plus, the Amal carb has been rendered practically useless because the motor is now scavenging so well, it drew the entire fuel circuit dangerously lean. The Amal 930 has a pressed pilot jet and is not replaceable, and it is so lean in the pilot circuit that the bike will run and idle with the air screw turned in tight and completely closed. It should fall on it's face and die when that happens. I have a friend that has a freshly rebuilt 34mm Keihin CV carb off of a Rebel 250 that I'm going to grab Tuesday afternoon. he said to go ahead and try it out, and if it works, pay him $50, if it doesn't just drain it and bring it back. I eventually will install a pair of Mikuni TM32's, but my funds are drained at the moment and need to hold off on that for the time being.
Anyways, here's a short video I put together yesterday. The exhaust sounds killer! Kind of actually sounds like an old race bike.
