    My modified rod measures at 49.5 and is working really well so would appear to split the difference.

    Huh? No was not saying that was just letting you know a good starting point. By all means more info is good. Sounds like most go slightly leaner than me. 48.5-50mm

    I think Kevin says in one of his videos that the bevel on the end of the needle can vary .5mm, so would explain some of the differences.

    I would but there's nothing to add, it would read like this;

    (1) 3/4 turn leaner on rod, set idle

    (2) Brrraaaapppp!

    I believe mine measured 49.5 too, as delivered from Lectron.

    OK, Here is a new one that may or may not work for you. With the MS-3 rod, I am 17 & 1/4 turns in from when the rod actually starts to thread into its holder. Kind of hard to determine when it actually starts to thread. I started threading it in and then screwed it out until it was released and then started back in that exact spot. My guess is that even adapting for different conditions and bike demands that is going to put you within 1/2 turn of your happy place.

    the EZ way is to use this tool but it is $150 and not needed, Just get it close enough to start and then tune it a little and be done.

    This piece of kit should be supplied free of charge to those customers that get under your skin the most like me. To clarify, WHERE'S MY NEW ROD?

    Hey guys, still trying. Bike is still running fantastic everywhere but when you just crack the throttle. Went richer than delivered by half a turn and seemed to be the best yet. Went richer by another 1/4 turn and it got worse again (same symptoms, popping and farting on 0-5% throttle). Bike is fantastic above this point, almost 4T like torque delivery, but cruise with the throttle just cracked and it sound like its got asthma.

    Rode 400 km last Sunday, bike performed flawlessly, fuel economy was good, <4.5 lt/100km and that was flogging the crap out of it to keep up with mostly 1000cc + road bikes. The thing is amazing, but the blubbering at low throttle is killing the fun on the street. I filmed a bit with my phone yesterday (It's crap footage, just allows the blubbering to be heard), hoping someone might have a listen and say "You're an idiot, it's far to lean!" or something to that effect.

    It is somewhat hard for me to give help as your guys fuel is so different over here. The JD EFI tuners were not working at all with US settings on Australia before we sorted the mapping because the fuel is so different.

    That's understandable. I think I'll try half a turn richer just to make sure it's getting worse, then just lean it out 1/4 turn at a time till it's as close as I can get. love the carb, has more power everywhere. Just hoped it could cure the stumble, if not, just have to stop riding it slowly I guess :D

    No thank YOU and please do report back. The lower end ramp on the rod should be slightly less aggressive meaning you should be able to fine tune the rod more on the bottom and will have more usable range (turns).
