Is a Rotax a Rotax?

They do not blueprint them in the traditional sense of the word. By that I mean they are not machining them to tolerances like you would if you blueprinted a Briggs to “stock” specs. They can do things like true the crank and adjust the squish with base gaskets. I now most of those guys you mention, Speedsouth, CMW, and they are good people. At best they may be able to get another hp out of them when compared to one directly from Rotax.

All the rebuild work must be done by some one. In the case of Rotax, they have setup service centers who are authorized to rebuild them and re-seal them. The guys you mention are all certified service centers. SSC is taking a proactive approach to policing the service centers. Take a look at what they are doing in SoCal with the LAKC series. They are tearing them apart down there and SSC is puting them back together at no charge to the racer if they are legal. If not, they are going to discipline the service center. They know that some service centers a pushing the limits, particularly in the junior ranks, and they want to put a stop to it.

I’ve been to Rotax races whre they have broken the seals to check the engines. But where ever they have done that, they have had service centers on hand to re-seal them at no charge if they are legal. Where I have a problem with breaking the seals is when they don’t have a service center on hand to re-seal them. That costs the racer plenty to get it put back together.
