Topic: Spark Plug Question

[Swede]

I have done a few modifications that would affect my tuning such as 4-1 exhaust and velocity stacks I did up the main jet size after doing this.  Last night I pulled the plugs and they have a nice tan color to them.  My question is would it still be useful to do a plug chop? I was just wondering if it would be possible to be running lean or rich at different throttle positions. 

Thanks

Try doing them at an idle then half then wide open. You will know for sure then.
