Introducing the New Generation ESP 30.5cc top end kits.

ESP 4-Bolt 36mm Modified "New Gen High Torque" CHAMPIONSHIP PORTED Zen 30.5cc kit +2mm stuffed crankshaft

(Written by Doug @ ESP) ESP has discontinued the ever popular 4-bolt Championship Ported 30.5cc kit, but the good news is, it is replaced with New Generation Championship Ported 30.5cc kits. (both with the higher performance level Championship porting over my lower level race porting kits).

This is the ESP 30.5cc New Generation High Torque kit .

Power is very similar to the discontinued kit, but a tad more power and a slightly wider usable power curve.

Great for scooters, RC cars, and Helicopter flyers are loving the power and smoothness of the ESP 30.5cc kit.

Peak power is about 6.4 hp, (with the DDM HPI Baja side mount pipe), on the calibrated ESP dyno (Note, ESP may have the only calibrated dyno in the industry), at about 13,800 RPM, and will rev between 17,000 and 18,000 rpm.

Different pipes will yield different results in performance (The Quick Draw hot pipe would make it rev higher, but lose some low end grunt,--for one example).

Usually, the stock clutch spring works well with this porting.

This it the </Strong> version of the ESP 30.5cc kit, if you are interested in the "High Rev" 30.5cc kit - see item cc286HR

As always with ESP, you can expect top performance (with a good set up and proper carb tuning), quality control that is almost impossible to beat, with attention to detail that is unmatched in the industry.

I highly recommend using the Zenoah G240/G270/G290 sealed 3rd crank bearing, (Replaces your large diameter crank seal, if your not using the 3rd bearing now. Not sold with the kit).

Now it is time to go out and beat your friends with those more expensive engines from the other guys. I feel sorry for them; I know your friends work hard for their money also and I am sure they are nice people. I hope they dont take it too hard.

If this kit is being used with Zenoah watercooled engines (or Airplane engines) the DD327 crankshaft, which is longer, must be used in place of the dd308/3312/dd324.

Fits 4-Bolt Crankcases (G240RC/G270RC Only.) This 4-bolt cylinder is NOT compatible with 2-bolt engines or cases!

 

Please Note: These Head Kits are All based around Genuine Zenoah heads, and are Approximately 37.87mm, If you are using KM bottom ends, they must be the Original E001 4 Bolt cases which are Approx 37.97mm.
