Stock is fine but I think more is better

So much will depend on your engine build and fuel used.
On a stock K5 engine you will gain 4 hp to the rear wheel by using the older style 44mm Lectron carb.
Alward25 and I built a Supermoto engine for a guy and we are using the new 44mm High Velocity Lectron.
Ill post our findings on it when they become available.
You can use the older 86-88 cylinders on the newer 89-04 cases but you really don't need to.
There is plenty of power to be had from the newer cylinders.
The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

Would you recommend that carb for motocross? Im looking for "4 stroke" type power. Strong down low with a solid mid range and decent top.

No way.
Get a 38mm quad vent Airstriker.
More power, smoother acceleration, better all the way around for MX..
