Lectron 44

2.044 on a 5.2XL rod
PJ 0.75 turns out

almost bang on what they told me it would be.

I know there is some very good baseline settings for both the 44 lectron and 39 pwk listed throughout this thread. Just wondering if anyone has some advice on baseline settings for the 41 pwk pro series and/or 38 air striker.

I rode my 1988 KX 500 engine today, and the jetting seems very lean.  The motor stumbles and just seems generally unhappy, though it idles and starts well.  The motor has been bored to 88 mm, has a Wossner forged piston, 89-up CR 500 pipe, stock carb, and stock ignition in the middle timing setting.  What do you guys suggest for main jet, pilot jet, needle jet, needle clip setting, etc?  I'm pretty far out of my element, and I'm not even sure where to start now that the motor is bigger.  Any help would be appreciated.  Thank you!

I forgot to add that OKC is at 1,100' and I sometimes ride in SE Oklahoma at around 400'.  Thank you!

It was 57 degrees Fahrenheit today.

Pro Circuit recommends the following at sea level for a stock bore
Main 170    
Pilot 60    
Needle STD    
Clip 3rd    
Air Screw 1.5

But, your bigger bore dictates smaller jetting.
What is currently in your carb?

whatever you do, don't read your plug...as that will tell you what's going on.

Thank you Sandblaster. I will get the carb off and see what I have in there. i just needed a starting point to see how far off I was.
