660 raptor rev box

[jmann660]

I bought a white bros rev box for my quad and now i have a hard time getting it to start when it cold out side. I have to jump it for the first start and soon as it warms up it starts right up. I was wondering if i bought a better coil to increase the spark it might solve my problem. Please give me some ideas to solve my problem. THANK YOU

You can try a coil but the main reason it won't start in the time is too far advanced in that CDI
