125-200cc Best small bore MX combo

What is every bodies thoughts on the best combo for a MX bike. 144 or 165? Lectron, Mikuni or Keihin. Really interested to here every ones opinion. I currently have a 2013WR 125 with a 144 kit and a FMF fatty and standard carb with RM needle. Also have the CR ignition.
Thanks in advance

Read npthing but good things about the lectron.

Mx humm what type of rider are you begining or pro? I guess begining ignore everyone here and just get on the track see what you like for yourself yes 144 165 are very popular so are lectrons.
Personally i would master the 125 full throttle everywhere then upgrade too lectron if you cabt get to grips with the current carb then chuck a 144 kit on next season when you re piston and bore it.

I am neither beginner or pro. I would say a good intermediate rider. I have had all breeds and sizes of current 4 strokes and also raced before the 4 stroke era. There is no doubting that the new 4 strokes are very easy to ride fast. To be competitive on the 144 you have to do everything right. No room for errors. Basically I want to know is will a 165 make a better mx bike than a 144. Is a lectron better for mx or would I just be wasting my money. Maybe most people on this forum are into riding, other than mx. Just keen to here other peoples thoughts. So far I still have no idea.

After riding with the lectron I doubt I'll ever go back to a standard jetted carb.

For average riders id say yes the 165 helps to get momentum going out of corners
If you are a fast MX rider a 144 or even a 125 is probably better .
Lot of young guys and kids like the 125 or a 139 .
I am running a 39mm mikuni and Id say that's good for MX
As for a pipe - a pro circuit or Scalvini pipe .

Do you like the CR ignition ? That would also be better for MX .

To me the 165 wasnt the best mxer... it has more torque but doesnt rev as good as a 150/144/125.... I liked the 150 the best for mx because it had the best of both torque and top power (seat of the pants)... this was only with about 30 laps on a track that was mix sx and mx.... I think the Keihn was better than the Mikuni by far and the lectron was at least as good as the Keihn, but I didnt ride the lectron on a mx track..... I had the Mikuni working good but it seemed sensitive to altitude, temp, humidity where the Keihn didnt care so much....

The track i rode the 165 on was fairly flat so depends on the track also.... a hilly track the 165 will be better
