As I have alluded to several times in other threads I have been working on a 125/144/165 specific Lectron rod. These small bore bikes with huge carbs need a little something different. Most are having to run to much powerjet (2.5-3 out)which makes it run rich in the mid and while it runs very good it can be better. Basically these bikes like lean bottom for response, normal mid jetting and rich on top. My new custom rod does this, lean bottom (snappy) normal mid, and then goes rich about mid throttle up (progressively). I had this rod done but was only 95% happy with it so did more testing this weekend and nailed it. My bike is a rocket from zero to WFO. I will be sending this rod to Lectron to duplicate and will have some to offer those that have their bikes running good but are at 2 or better on the PJ. Blake rode my bike yesterday and said, "wow, that makes a lot of power and way more top than I remember" I am really pleased with this design. Also running to much PJ affected my fuel milage. It is far better now while still making more power. Basically we are taking the work off the PJ and getting it back on the rod and using the PJ for a fine tune like it was meant to be. Working on getting these built soon. thanks. Kelly Motosportz
That's great I am at 2 1/2 on the power jet on my 144 it runs great. The last ride I went on was mostly on the pipe and noticed I used a lot of fuel. I can't wait to try a new rod that would improve that.
This question doesn't necessarily belong in this topic but since its related to lectrons and tuning I figure why not. How do lectrons go about adjusting for different fuels. I am planning to buy one for my bike when one is released for my application(250f). I will be running 100ll aviation. Fuel as pump gas in my area causes more problems then ever. any info is appreciated.
you do need a little different setup for race gas. Lectron knows all about this and what to do. I really do not as I am a pump gas guy. they also make a aluminum fuel bowl that is not see through and holds more for alcohol etc.
I may be interested in your "improved" rod (that just doesn't sound right). My pj is at 2.5 turns out and it runs great but having more adjustment available in the pj would be a good thing. Keep us posted on availability!
Will be a few weeks as i think i am racing my 165 this weekend and want to run my new rod. Then I will send it to Lectron to duplicate.
Hi again, Now I am also at 2.5 out on the pj, which made the rest too rich, so I had to lean out the rod another 1/4 turn for a total of 3/4 out from delivered. Runs great but I noticed it was quite thirsty. Im looking forward to the improved rod. By the way, I think it would be easier for most if we referred to the fuel metering rod as a wing instead. Being an ex-soaring pilot I understand the benefit and function that way, but not when using the archaic engineering term. The name would then refer to the application, not primarily the correct design term.
The manufacture calls it a metering rod. But your right, the original design was by a pilot looking out the window at his wing and pondering a carb needle working within those principles.
Was just talking with Lectro today about it. Might have them next week and then will need to test and verify results then good to go. Don't want to sell stuff that does not work / proven.
Hey Kelly - I want to be a "tester" too. As soon as your prototype run is back, let me know so I can buy one from you.
Are they for you to test or sell? If sell I would like one(or maybe a tester lol). Also have you figured out what the damage will be for them?
