D-Fresh,
Look at it this way. If it is out of spec Rotax is giving you a new cylinder! A new cylinder cost a lot of $$$. Lets say you don’t do the program and you sell it at the end of the season. The first question that will be asked is, is it Rotax legal? If your a straight shooter you will have to tell them that you don’t know because the cylinder my be out of spec. Then, the value of your engine goes to zero. It isn’t often that Rotax gives anything away for free! Say, Thank-You Thank-You Thank-You and smile alot. As they say in Napcar- Git-R-done!
