I go over my Pig daily for loose stuff and fix anything I find before it becomes a failure. The main thing I do to prolong engine life is to run it a touch rich for plenty of oil. Mine is jetted to run smooth under throttle and four-stroke a bit when cruising. I run 40:1 with good oil and the rich jetting lowers engine wear. I also don't scream my motor since I run a higher gear to lower my normal cruise rpm's.
Thanks! Were you able to see the bike I have? Not sure if the engine would actually fit there..
