All I can say is try it.
I think you know my opinion, but in case not, I'll repeat. LOL
The new timing from 1800 rpm to 2500 may result in pinging during part throttle acceleration and uphills.
You now know how to change it, so you can experiment. No harm, no foul. Just back off the throttle if it starts to detonate under heavy load - that's when there can be serious harm.:eek:
