I finally got around to changing from a Be3 to a Be5 , also I had thought I had a 118 on there but it was a 116 , hoping I didn't do any harm.
But wow what an amazing difference in pickup , now was it the change in the atomizer or the jet that gave this improvement ? So now I'm running with the 140/BE5/118 and the 50/120 , I always did have the 140 on the stack. I'm at 340 miles and wearing a big ass grin.

Ok after doing some reading I think I see what happened the BE5 is richer on the low end rpms and as well richer in the upper level rpm compared to the BE3 but going to a bigger jet pretty much rich ended up the upper end in addition to the richer of the BE5. So I can see how the BE5 may be an all around good atomizer and simply adjust the air jet and the main jet, hope that makes sense.

I have dr177 24mm carb and road 2.0 with be5 ac 140 and 122 main 120/50 pilot and yes runs a tad rich on pilot but you can thrash the ass of it wot with brown plug. Compromise , rather not seize at 60 plus mph than have a slight splutter on one eighth throttle. Took me a while to get there but guys on here helped me find the right balance.

You should just keep adding to your original build thread, Lynn. That way, you have a continuous work log you can refer back to down the road.

That process starts to fail once you're swapping motors between bikes, but you're not there...yet.

Yes so true , when I get there I'll do that. Some day I will want to swap out this motor for something a bit more roddy.
