There are several things to be learned from this cylinder...
I don't have any measurements yet but hope too soon.
The first thing you learn is that there is very little difference between a stock cylinder and a SR cylinder.
The biggest differences I see is the amount of clean up.
Let's take a look..
I like to clean up the exhaust port and polish but it does not really make any HP.
Rather, by polishing the surfaces it gives carbon less chance to build up and will keep the new HP you are making longer...
These measurements are approx and provided by member Karlosthejackel
Exhaust port:
Height 34mm
Width 50mm (in a straight line)
Top of exhaust port to deck 48mm
Base to deck 143mm
Also
top of inlet centre port to deck 70mm
length of inlet 65mm
width of inlet at narrowest point as T shaped 22mm
All these measurements correspond to the stock 89-04 cylinders.
The biggest take from this cylinder is that Kawasaki did a pretty good job of setting it up for stock usage.
Yes, there are area's that can be improved.
If you want serious HP gains over stock, the standard Team Green mods are simply done to get the cylinder ready to make more power. Once these mods are done, then you lift, lower, up the compression, down the compression, ect to get the power where you want it.
