Other i nformation:

There is no problem with the RC valves hitting the piston due to the thin thickness of the cylinder wall. This is not a problem because our kit uses it differently
cylinders, unmodified NSR250. They are real-cylinder Honda OEM, built and plated in Japan for their traditional high quality.

The RC valves are easier to adjust than ever on the 300 kit, since there is only one screw adjustment to play with, and each cylinder marked in the correct position 'fully open' for simple setting.

is not possible to give exact jet requirements for its application area and due to the different atmospheric conditions in Worldwide. However, the following are some basic settings from which to work:



MC21 Ends lower standard, yarn splicing, TYGA Pipes, airbox mod lid with filter.

PwrJ - Std./Std.



Tip: temperatures cooler, higher pressure and / or lower humidity require a more intense jet. The high altitude requires leaner settings.
