Upgrading CDI Box - does it matter? By sillylittleboy (Read 1,213 times)

So when I ordered my new starter relay, I figured it was a good time to pick up a few other parts/spares. They offered this "Upgraded Racing CDI Box" for $20, so I thought it was worth a shot.  Then after I ordered it I found this video review:

This guy seemed pretty thorough and unbiased with his testing of the three CDI units.  His results with the Racing CDI was no improvement in performance and maybe even a reduction, plus it also created cold start issues (took more cranks to get it started after a day or two of inactivity).

I had thought I'd read something about an upgrade on the CDI box will help with cold start issues.  Mine has always taken at least 4-5 cranks on the starter before it starts up.  It runs fine after that and starts up quick when less than eight hours of inactivity.

Has anyone had any luck with CDI box upgrades?

I put a MSD box on my 66 Pontiac years ago, works real well. My scooter is still running it's factory box, it still works fine, engine always fires before it has turned 2 revolutions. I just bought a new cdi for it though.... (after 5 years of use, thought it might be good to have a spare near by). Being total satisfied with the original, and with my scooters performance, and economy figures, i decided to get one just like it. It took a few weeks to be delivered, but only cost $3.70, and shipped for free.

Some will swear by the racing or high performance boxes......I'm not going racing with, or looking for high performance from, an eight horsepower scooter,  so in my mind......they are a waste of money.
