I must say this pipe is definitely expensive, but at the same time it is worth every penny! The paint is holding up right now but we'll see how long that lasts. It took my stock Fa50 from going 27-28mph to 33-34 mph without even upjetting! But beware you definitely will want to upjet if you don't like seized engines. I put a #85 jet in the stock VM12 Mikuni carb and it has been working fine for me. You might be able to get away with a #82 or 82.5 jet but it might run a little lean. Personally, I would suggest putting a Mikuni VM16 or VM18 on there if you want more power. It seems now that I have the MLM pipe on there the bike is limited down to how much air and fuel it can get in and not out. Overall this is a great purchase!

After trying the MLM Techno Circuit, and dragging it on the concrete during a sharp left turn, I decided to give this pipe a go.
I paired this with the VM18, MLM Intake port matched to the reed block, and Dual Stage Power Reeds. The bottom end suffers the most until about 10mph. At about 18 mph, you're on the pipe with a power band all the way to 34mph. After that my FA50 doesn't have the power to continue without me tucking or having a tail wind. I have buried the needle at 40mph tucked with this pipe.
Build quality is on point, we'll see how the paint lasts. The sound of this pipe is amazing. I love rolling into stopped traffic, getting the green light, and laying on the pipe while flying by stopped cars. It's loud enough for people to hear you, but not too loud to be annoying.
If you want better bottom end buy the Techno Circuit. I plan on adding Red springs to my clutch to help the bottom end. Will report back when done.

I want to like this pipe a lot more but I have had it about 8 months and the paint is already very chipped and I'm getting large rust spots. I will be repainting and I think it gives decent performance but I would never buy anything from MLM again I don't think the quality is there for the price I expected more
Great Pipe, must have for your FA50!
