I recently purchased a 212 predator motor and the bike I have had pre drilled hole in the mounting plate where someone mounted a B&S. the existing holes are very close to where I need the 212 holes need to be. So close that I can't drill new ones without overlapping the old ones. I have seen that all engine plates come with vertical milled slots. Due to my issue, would drilling horizontal slots work or would the engine torque cause the bolts to slip and throw the chain off? Thanks!
