Metering Rods | PRO-SERIES, BILLETRON, and Legacy Carbs

Have the Lectron 38H on my 2017 KTM 300 xc-w. I was happy with it, but was playing w/ the idea of an upgrade in the future. I came upon information that the xcelerator metering rod from the Pro carb. was availablefor the Lectron 38H & the reviews were all positive. I have to say it's a fantastic 'bang for the buck' modification. I feel more torque & power across the board. I noticed it most when the bike was climbingsome really big hills I used to struggle with. I wish I could have seen the look on my own face when I realized the bikejust seemed to have a LOT more power! I highly recommend trying this xcelerator metering rod. I see no downside.

I never would have thought that this metering rod would make this much difference!!!My ole my..If youre on the ropes about getting one, dont hesitate..You will not be sorry!!Im running the latest billetron pro 38 on a 2002 Honda cr250r. X2 torque and this thing pulls so freaking hard thru all gears!!

This rod even works well for slow technical riding. Bottom end is stronger and much crisper off idle. It's by no means aggressive or unpredictable.

When we started testing the Lectron Pro w/tps on my 2022 YZ125 prior to the release last spring we were able to come up with some settings in one day at the test track that far exceeded my expectations and very good, dyno verified jetting with the OEM Keihin. Most noticeable improvements for everyone that rode the bike was how connected it felt from closed to mid throttle opening. That translated to an immediate boost in confidence in short jump approaches out of tight corners and technical rhythm sections especially for the more beginner and intermediate riders. Mid - top was still very potent, similar to the keihin but the transition was seamless and much more predictable lap after lap. Most felt there was also a slight advantage on over rev with the Lectron. Overall the improvements, especially for a 125 were a game changer for fun factor and rideability of the bike. Fast forward a few months and the new Xcelerator Rods showed up in mail. Hard to believe you could make this performance package any better but they did. With a 1/8 turn adjustment to the previous 2-2 rod length and a 1/4 turn adjustment to the torque jet a new level of wow factor was unlocked. The amount of torque and roll on power the bike has is incredible and almost unbelievable for a stock bore 125. The entire tone of the engine changed. Several riders commented it sounds like a 125 that turns into a 250 in the mid - top rpm range. Where the original rod felt like it shined the most from closed to half throttle, the Xcelerator added to that already dominant characteristic and turned a slight mid - top advantage into an absolute landslide. After 20 years of singing the praises of proper OEM carb setup, Matt and the team at Lectron has finally come up with something so good it's become a no brainer for what I'll use and recommend going forward.

I ride a 2020 Yamaha YZ125X that had the Mikuni TMX. I also had the Lectron H-Series, but was missing the grunt down low thats comparable to a PWK Airstriker 36mm or 38mm. Once the addition of the Torque Jet was introduced, the playing field was leveled. The XCELERATOR Metering Rod added is the game changer adding an extra dose/charge, whatever you want to call it, of fuel to not bog, stutter, load the motor. The best description is a 36mm below mid rpm & 38mm above it with room to spare up top at 12,700rpm. The added metering rod feels like a high comp head(I run a high volume dome with low compression). I have sold my PWK A/S mic dropped.
