My question is this, my buddy has the 1986 atc 250r, broke the chain, which slapped the left case (no case saver against my advice) and now needs a left side engine case. As you guys know already they are not cheap. So while looking on ebay we noticed that the cr250r motor of the same year looks pretty damn close to the same. Now I know that the atc has a counterbalancer in it, but is that the only difference? The next thing is are the mounts the same? the engines we looked at (pics only) looked like the same mounts. We are just hoping to save some bucks here. The cost of the cr motor is lower than just the left case for the atc. See the dilema. BTW love the site.
