apparently the G2 uses an electronic ignition retard (4 deg) in gears 1-3 to prevent squids from looping the bike and to reduce noise levels. Eliminating this feature should improve power across the board. Now what is best: short the appropriate wires disabling the retard in the first 3 gears or installing a hard ignition advance which will make up for the retard.
Any opinions out there??? :whine:
installing an advancing device will affect all gears resulting in too much advance in gears 4-6 causing detonation and engine damage unless race fuel is used in which case the timing in gears 1-3 will be less than optimal. Wrong choice.
Not as simple as shorting wires together as the ECM looks at the gear position switch which sends a different resistance for each gear to the ECM. I have not looked at whether 6th is low or high resistance (short or open circuit).
I think there's a timing retard eliminator out there that you can buy for the 650 that will put a resistor in line that will make the bike always think its in one of the upper gears. Very common for Suzuki's. Look for a TRE. They plug into the harness.
I have a timing retard eliminator on my GSXR 750, can't recall off the top of my head what brand it is, but here's a random website I found with them for the SV650 that I found with a quick online search: http://www.jbracing.co.uk/IGNITION_TIMING_RETARD_ELIMINATOR.CFM?ProdID=36&category=14 (http://www.jbracing.co.uk/IGNITION_TIMING_RETARD_ELIMINATOR.CFM?ProdID=36&category=14). Though it's a European site it still shows you what it is and how it works, they're very simple to just plug in and go. :thumb:
