Racing CDI/ IRK /ORK's good or bad?

[makedonski]

hey experts, i just wanted to know if racing cdi is a smart thing to put on my yx140. i heard it aint good for the engine as you can push it too much in revs. also i love to drag race sooo is an irk/ork good? nd I have an 26mm MOLKT carbie, what do you think of that? i know i should get a jap one but is it a huge difference?

Cdi is worthless unless you get one with adjustable advance curves but thats expensive. Flywheel is debatable, faster spin up vs increased traction etc

I did the IRK on my yx140 and the better CDI. Rev's it's head off now but has 0 torque. I wouldn't bother. Carby won't make a huge difference either. Don't get me wrong there is a difference, just not a massive one.
