Overdrive in Viper.


Have a machine shop or send your primary to LP and have them shave the primary down in the bottom. I think its 30 thoudandths off both sidesbut cant remember. Alot of guys on here say the overdrive kit sheath doesnt work well. I have the shaved primary and geared down one tooth with no loss.
 
i talked with bob at Lightning Pro last week he said for their overdrive mod send primary and secondary he mods both to get a true full overdrive shift. ski
