Honda CBR125R, Honda GN4 10W40, 62 miles

[craigq]

I bought a new bike, 2007 Honda CBR125R. Engine is a 125cc/7.6cu-in thumper, compression ratio 11.0:1, uses Honda's PGM-FI EFI system. Oil capacity is 1.3L, oil changes are about 1.0L. There is no oil filter to change, just a simple strainer screen to clean every 7500 miles. Honda's recommended OCI's are every 2500 miles. Here's the analysis of the initial fill:

I think you will probably see similar results with a couple more short oci's.
I'm curious what sort of fuel are you using? And also how the throttle resonse, etc, is with that fuel injection?

Gotta be a fun bike!

The first tank was whatever the dealer supplied. As per the owner's manual suggestion, the fuel I'm using so far has been 87 pump octane number, Shell "Bronze" 87.

So far throttle delivery is smooth with the fuel injection, no hints of stumbling anywhere in the RPM range, starting is quite easy (both warm and cold starts).
