[QUOTE="83gl1200, post: 126611, member: 3756"] Maybe this question would help others on an upgrade path with the pvc manifold so I'll ask here. I am using dkl's manifold design, with a 34/3, and it runs great on the bike while stuck in the driveway. Many things left to do to get bike on the road... But the vw carb I bought is a lemon, I can't get it to stop leaking almost the entire contents of the bowl when the bike is off, so I have to replace the darn thing. I'm contemplating going to the 32dft on this manifold at least temporarily, since the cost isn't any more than another china 34/3. My bike has a 1200 case with 1100 heads, I intend to put on better coils not sure of type, but I can't swing any kind of c5 ignition. And I want mainly low end torque if I can only have one thing, but I don't want this modded bike to poop out at 85. If I want to smoke a crotch rocket with this bike, and have max torque down low, can I do it with a 32dft on a 2-1 adapter plate on this 1" all the way through manifold? Or if going for both torque down low and no end to my top end, would I have to go to something like the vw plenum with it's added volume, chokes like you use, and larger runners like you are using and yet another bigger carb like you have gone to most recently? Whats the best upgrade path and where will it end, with me having to replace the 32dft also after upgrading manifold to a design like yours with larger runners and vw plenum with chokes, and heat. How close to getting the most from this engine would I be with 32dft on this manifold I guess is the question, or should I skip the 32dft and go even larger to the 36 24 36 abcdefg or whatever it is you are using now, then replace manifold later? Trying to get some performance on a budget from this one off engine... I already sold my working stock carbs to have money to do something better after the vw carb proved single carb will work well, just need to settle on the next carb. [/QUOTE]
