I heard every engine whether it's a car or motorcycle, you have to break it in the first 600-1000 miles. Cars and motorcycles today are removing things like water temp and tachs, which sucks. I heard you have to keep in between 1k to 4k rpm and fluctuate it.
You guys have any advice on how to break in an engine without a tach? I doubt they already broke it in for you.
Any links to aftermarket tach meters where I can just plug and play?
