what do you think you will gain by adding more timing?
...better throttle response and more hp.
do you know what timing effects in the engine, as in what all you will get or not get by advancing the timing?
...i believe that timing can affect the pressures inside the engine during combustion and that if the timing is advanced too much at near peak rpm, top end will suffer, cause timing needs to be retarded the more rpm's the engine spins. that is what i read in one of my 2-stroke books. timing helps the low-midrange, but can make the top end feel flat.....my banshee atv has proven this. i modded the stock timing plate for +4, and the bottom-midrange improved greatly, along with the throttle response, but the top end felt flat.
what leads you to believe you need more ignition timing in your engine?
...not my viper engine, but my spare srx motor that i have, i was kicking around this idea for. i thought if the viper and srx have the same max operating rpms stock (as yamaha suggests), then the would have the same/comparable timing @ those peak rpms...but everyone says that the viper's have a hotter midrange, so i was thinking that if the viper cdi went on a srx, you would have better throttle response, little more midrange hp (like 2hp) and it would be more fun when on/off the throttle in the twisties.
so mrviper, have you ever tried this before?? would this work??
