Fitting this Power Up Kit to your Honda MSX125/GROM gives a significant increase in top end performance and over rev. Peak hp is moved from 7,000rpm (std) up to 8,000rpm, with a 1.6hp gain at peak.

Fitting the i-Map Fuel Injection Controller is a necessary modification to avoid the engine running lean and being damaged. Running the KITACO Type 2 camshaft without the i-Map is NOT an option!

The wire harness requires modification and the documents are included with the kit, or can be viewed here: http://www.kitaco.co.jp/data/product/link/instaling_manual/kitaco_installing_manual_grom_imap.html

The i-Map is shipped with “setting #3” activated. This is the basic map for this kit, but the map can be modified using the optional i-Map interface cable and software downloadable from the KITACO website:
