#20185 thebru (User) Gold Boarder Posts: 947 Manifold Porting 5 Years, 2 Months ago   Was thinking of porting my manifold, basically rounding off the corners, as I have read about here and other places. However, a NoPork thread mentioned I would need to re-jet if I did this. Is this true?? Not happening if I have to re-jet.   Logged       The administrator has disabled public write access. #20188 04Roadrider (User) Fresh Boarder Posts: 62 Re:Manifold Porting 5 Years, 2 Months ago   Not positive on this, but my understanding is that any time you change the way your engine breathes in, you must rejet to compensate for the different air/fuel mix entering the motor. I'm sure one of the experts here can give you better info. Good luck!   Logged     04 Midnight Silverado with HardKrome 3inch Big Straights   The administrator has disabled public write access. #20189 Musky (User) Platinum Boarder Posts: 15137 Re:Manifold Porting 5 Years, 2 Months ago   Hey bru What else have you done besides pipes? From what I understand porting makes you richer.   Logged       The administrator has disabled public write access. #20194 thebru (User) Gold Boarder Posts: 947 Re:Manifold Porting 5 Years, 2 Months ago   Only pipes. From what I understand it gives a better flow of both into the carb. Once it's in the manifold it's already mixed.   Logged       The administrator has disabled public write access. #20198 Musky (User) Platinum Boarder Posts: 15137 Re:Manifold Porting 5 Years, 2 Months ago   If all you've done is pipes and you don't want to jet I wouldn't bother with it.   Logged       The administrator has disabled public write access. #20202 Big Bear (Moderator) Who loves you , Baby? Moderator Posts: 6997 Re:Manifold Porting 5 Years, 2 Months ago   I'm running a ported manifold with stock jetting and a R/H 2/1 pipe. Airbox is drilled though. Here's how it feels:   Logged       The administrator has disabled public write access. #20216 thebru (User) Gold Boarder Posts: 947 Re:Manifold Porting 5 Years, 2 Months ago   BEAR, I have also drilled the air box. Did you do the porting or buy one? Feel any difference, was it worth it?   Logged       The administrator has disabled public write access. #20232 Curt (Moderator) Never to old to ride! Moderator Posts: 12511 Re:Manifold Porting 5 Years, 2 Months ago   I didn't port mine until I put the BAK on. I wouldn't do it unless you do an air cleaner. Take from me jetting can be REAL FUN!   Logged     My Site Black Ice is Shiny, Black Ice is Deadly, Ya Wanna Ride My BlackIce?   The administrator has disabled public write access. #20255 Big Bear (Moderator) Who loves you , Baby?

I bought the barons stock ported.Yes , I personally feel it was worth it. Yes I could "feel" it (seat of pants meter). Anytime you can "bolt-on" a HP or 4 in about 2 hours time, its worth it.   Logged       The administrator has disabled public write access. #20264 Roadkill1962 (User) ΜΟΛΩΝ ΛΑΒΕ Platinum Boarder Posts: 3213 Re:Manifold Porting 5 Years, 2 Months ago   bru-- I'll let you know...just got done porting mine, and I dropped in a smaller DJ 170 jet size to make up for the added richness the manifold. She's almost ready to ride...I'll let you know my review! And if you have a Dremel, do it yourself...save the $140.
