1986 Cr 125 cylinder bore

[rakplk]

I have taken the cylinder sleeve outta my jug on my bike because it has been overbored to the max 2.00 and have a new sleeve to put in, but it's not the same alike. The old sleeve has a center groove and my new one doesn't. It also has a lip at the top and the old on didn't. It's just straight all the way down. Am I gonna have to have the jug bored out to fit my new wiseco std sleeve? :bang:
