    Amal Concentric Carburetter

    Guys

    Am having a Lightning 535 and now it runs on a Mikuni V28, am looking at getting a Amal Concentric, can somebody explain on the pros and cons or is it advisable to continue with the same, what would be the best carb for highway riding.

      Any specific reason for a concentric? why not try an CV carb from the AVL engine with a bigger jet? BS29 is the model.

        Am not sure on how a monobloc or a concentric makes a difference, my mechanic was speaking high about concentric, he said if u get concentric it wud be the best for my bike. Mine currently runs on a MK28, am sure BS29 wud not make much of a difference. Pls make me understand the diff between a concentric and a monobloc, also is Amal better than Mikuni.

          You can even try the Big Badass Mikuni BS32 from the 220. Although it has BS in its name, trust me its awesome and no BS [bullshit]

              edit - try the BS29, or the BS32 from the P220. You will have to upjet to 120-130 mains, and 15 pilot or something. But it will be worth the upgrade.

                  If you have a BS29, then first i suggest upjetting the carburettor, and installing a free Flow airfilter ( for experimentation, so get the 150-200 bucks conical filter thats commonly available.

                  If you still feel a lag in performance, than go for the BS32.

                      ^^ did u upjet after installing the K&N?? Its needed else, the filter wont be of much use.

                      Try that.

                        Any difference between these generic cone type air filters and K&N cone type?

                          They're a whole lotta fun but a real B***ch to maintain. Unless you're very adept with carbs or have a really good mechanic, you're better off with a BS32. Your 535 is severly starved with the VM28 you're currently running.

                          I can't help you much with the technical differences but I've ridden an amal shod 350 and man that thing could move. I'm pretty sure you'll get similar juice from the BS32. Besides you'll get parts all over.

                          (Note: please do check manifold sizes for a match)

                            Yes it should but you do need to make sure you have a perfect fit. Unmatched sizes will cause you more problems than solve.

                              there isnt much difference in air flow, the difference is in filtration of the air. The generic conical type will allow more dust inside the engine, whereas K&N will filter it properly.

                              So you can try the generic conical one to understand what would your bike do with a free flow filter, but not for regular or heavy usage.

                              Its best suited to races, or those one time performance requirements, where free air is paramount, compared to filtration or quality of air.
