I am building a 600 improver for 1000' speed runs, it used to be a 97 500xt, but, won that class so decided to up to 600 imp., will I be able to use the 500 ignition or is there a different ignition I should use?
 

Timing curve is most likely dif. But bumping up to 600 imp now your in with 3 cyc cats and f6 srx 600's doo formula 3 exc. Is a twin gonna compeat?

I run mostly local runs, My 97 500xt was running 98.5 in 1000', but I do alot of testing as soon as the test lake freezes, so I really don't concern myself with the twins vs triples theory
 
Well if your having fun and no real local comp game on. Post some pics we all love pics
Well your doing better than me I had a stock sx 700 w/pipes only ran 99.5 in 1000ft Had no place to tune in

Our 97 700 sx stock with pipes(my son's trail sled) run's 102-105 in 1000', have not been testing that one, that's for trail riding,

I am fortunate enough to share the cost of a shaved test track at a local lake out of the way from snoopers and other disturbances. can get alot done in 8 hrs of testing every weekend if the weather holds.
