how to fit a ignition advancer to 650 suzuki bandit?

Answer 1

Igntion advance is calculated by the CDI from Crank position, rpm and tps (Throttle position sensor position) - ignition advancers replace the oem target fitted to the right hand end of the crankshaft with an afternmarket one that fools the CDI into thinking that the crank is not as far towards TDC as it actually is - so advancing the ignition timing. This gives the potential for more power to be extracted from the engine as you can use a higher octane fuel and get the most benefit from it.

On the bandit you will find an engine cover on the r'h side of the engine at the front - behind this is the igntion pickup and tagret on the crankshaft end, The crankshaft end has a hex socket in it to take an allen key and the target is held on with a nut. Hold the crankshaft and undo the nut (it will be tight) remove the target and fir the new one. Retighten the nut - check with a manual for the torque for this; it is important to get this tightened correctly as if not it will do a lot of damage if it comes undone whilst the engine is revving at 10k rpm

Answer 2

I assume that you are talking about an aftermarket pulse trigger that bolts to the end of the crankshaft. I am not familiar with those bikes (BTW is it a 600 Bandit?), but, typically you remove the engine cover on whatever side the ignition trigger is on remove the stock one and install the new, then replace the cover.
Theres no adjustments or anything, I would also expect that there will be some installation instructions along with the box it comes in.

Answer 3

Ignition advance is controlled by the throttle position sensor fitted to the right most carburettor throttle spindle.

If you want to alter the presets you can either rotate the sensor ( not recommended) or fit an inline potentiometer in the cable harness, but be warned - altering the mapping usually just mucks up the base settings. Suzuki spent a lot of time getting it right.
