I purchased a billetron pro 38 for my 2020 yz125. Shipping was fast and install went perfect. Had it installed in 15 mins. I had to adjust the xcelerator metering rod 3/4 turn leaner to drop the idle. I took the bike to the track and it ran great small adjustments to the power jet and the torque jet to make it perfect. With the pro 38 coming from the older h series that was on the bike before. The new pro 38 has WAY more bottom end and allows the bike to be revved out longer so in smaller straight aways you now don’t have to shift as much. Definitely improved my lap times. Over all I recommend the pro 38 to anyone! Only thing I would change would be more detailed instructions for the pro series. It seemed that the instructions where for the same for all the other carbs before the pro 38 series. With few additions. 5/5 stars love Lectron!
Carb arrived and packaged very nicely! Must admit it is a very good-looking carb. Install was very straightforward and took about a hour including throttle and cable. I did have a couple issues with tuning/setup but was fixed by your support team. I did not have to adjust the torque jet or power jet. The test ride was very impressive. The bottom hit is night and day vs the stock carb. I have not had the chance to open it up to WOT however 3/4 is also impressive. Looking forward to getting the bike in the dirt! Thank you Lectron, this carb has woken the sleeping beast. I have already started spreading the word on my groups Facebook page (DRZ 400 owners).
I have an oversized tank on my DR Z400s and leaves no access to the choke. I did purchase the extension kit. It shipped today.
We did our first test run yesterday. My son took 3 laps and came off the track and said, "This thing is insane". Said there was no bog at all and was able to pull power with ease. This was a short track and we're doing a big track this weekend, so I'll let you know how it goes.
I purchased the billetron pro for my 2009 Yz 300 . This carb was easy to install with no fit issues. All I did was turn the idle screw 1/2 a turn .
First ride was impressive, feels like a perfectly tuned carb at all throttle openings, instant response! I can lug up hills in first and keep a steady throttle in the whoops .
It feels like I have more control out of the turns with the instant throttle response.
Thanks Kristin for the amazing customer service and helping me select the billetron pro
My bike wouldn’t run for a year tinkering with oem carb. I bought the lectron put it on in 10 minutes and it fired right up after doing the starting procedure.
