It took awhile but a problem I had with my race scooters was spark. After trying a lot of combos this one took me by surprise when it added performance to my scooters and motorcycles right away
These are not offered anywhere else but you can buy the cheapo orange ones that are stock and have the same problems that I had over the years.
After being tricked by distributors on the orange coils I just stopped shipping them and buying them, they leaked and did not put out anymore voltage than cheap stock ones it just made me mad as hell so I fixed the problem.
I do not name names so play at your own risk.
This combo gave me great results. I get the NCY coil which is good and install the NGK wire and cap tha ship so it os not an off the shelf product like a lot of my products.
