You don't need to take it out. We don't have a 25 hour - or any other number - interval for service. We say "Listen to your engine and get used to how it usually sounds. The bearings will tell you when they are starting to wear, the sound changes and you will hear them grumble on spooldown." When the engine needs something, it will tell you. We firmly believe in the "if it ain't broke, don't fix it" philosophy.

Ron's here in the UK with us now, and has asked me to tell you that he has a spare XL200 which he will lend to good customers, if necessary, whilst their engine is with him. But he's not expecting to see your engine for a long time yet!
