predator tuning Q's
 

Hey guys,
I fixed my valve problem that I had..Now im ready to step up the tune a good bit..Now at WOT its hitting about 24.5 degrees of spark..What would be a target WOT spark be?? and on the predator it goes in percentage, what % would equal 1 degree of spark?? do you understand what I mean

Current WOT spark ~ 24.5
Adding 1% ~ 1.01
New ~ 1.01*24.5=24.745

Adding 5% ~ 1.05
New ~ 1.05*24.5=25.725

Make sense? As for how high...I wouldn't go over 8% (2 degrees). Keep an eye out for KR - especially around 4,000rpm @ WOT.

lets just say that I added 4% on 24.5..what would that be..Also, what do you mean by 8%..Thats 2 degrees of timing right?? that would put me at 26.5?? Is that to much for a N/A motor? what is a safe spark advance for a somewhat stock motor?
