Ok so I have a 1983 atc 250r cdi on my 86 atc 250r. Finally found one for a good priceand buddy sold me 2 for one deal. Also gave me a red tri z air box cover. But these cdi seem to be way thinner. The plugs which look the same are in the middle of the thinner cdi.There are also 2 ridges by Installed it and never seen a change in power. But due to all the water we just got Ill have to wait to really try it out. Any ideas?
