High Rev CDI on this engine?

[ATVer14]

I've got a 440EX that I bought used. It came with a WB CDI on it, and the engines got a 440 kit, high compression piston, ported head, TC national cam, bored carb, X-6 exhaust. I've heard on here that you should just go with a stock CDI to save the engine since no more power is being made after 9,200 or what ever the stock limit is. So my question is that even though I've got all these mods done to the engine, should I just leave the WB CDI, or should I drop the stock one back in it? Thanks

My little brother said your 300 was pretty sweet.

But do you have a website of the races that you race. I like to go to a couple this year.

Thanks

On that motor i would think you would notice a power difference if you put the stock one back on, but it won't hurt anything if you put the stock one back one either. They're real hard to start in the cold weather with the rev box but other than that your motor doesn't need the extra revs, in my opinion.

Bump, anyone else have any opinions?
