Executive Scooter

[Enviromoto]

Here is my latest project.

I named it the Executive scooter as this project would work well for someone on campus or a business guy who wants to leave the BMW at home.

Mods:
Front turn signal relocation
Red Pill Springs 11.5G Rollers
Porsche Hunter Green Paint
160cc Top End
MRP Performance Head
115 Main Jet
Iridium Sparkplug
UNI Intake
Electric Fuel Pump and Pressure Regulator
White Wall Tires
NCY Brake Reservoir Caps
Chrome Fan

What it used to look like.



During the transformation.

Motor out.




Tear down.




Not much bigger than stock but since I had to install a new base gasket anyways I decided to go with the largest big bore kit I could get without having to mill the case. 59.5mm 155cc with a MRP Performance head.







Some quick numbers on the MRP Performance head.

Stock head:
26mm Intake Valve Diameter
23mm Exhaust Valve Diameter
Intake Port 24mm
Exhaust Port 24mm

MRP Performance head:
27mm Intake Valve Diameter
23mm Exhaust Valve Diameter
Intake Port 28mm
Exhaust Port 27mm

So you can see that there is quite a bit of difference in port diameters. Lets hope this translates into power.

Nice work!

I like the way you salvaged that dumb stock airflow blocking chromed fan inlet cover and made it into a good looking trim ring.

What performance increase do you notice with your engine mods?

Thanks its not perfect but hey its a china scooter right

The performance gains were simply night and day. The big bore kit and head really woke this thing up. I weight 270 and have light weights and heavy pill springs in it so it isnt really a high speed monster. However she does pull wheelies alright and cruses along a 45 mph all day and takes off like a rocket. I ride with a bunch of 50's so top speed isnt really a issue.
