[QUOTE="EddieS'04, post: 1029651, member: 61136"] Steve, I recently found out the chain tensonors on my twin cam harley engine. Have a failure rate also. Harley recomends pulling the cover and cam plate every 17K miles, for inspection. The problem comes when the plastic guide fails. There will be metal against the chains. The motor can trash out . This point of lubrication is after the oil filter. The best of my motor is, hydralic tensonors. Early twin cam harley,s were spring loaded and many failures. If I choose to keep this harley. Im looking into a gear driven cam conversion from S&S or Andrews. I have already installed hi-po lifters and adjustable pushrods. My old harley was gear driven(74 shouvle head). Ran the crap out of it for about 80K. never broke it. Wish I never sold it. Lot of guys are turning there old shouvle heads' into stroker motors. The new 2017 harley 8valve motor is single cam now. Still chain driven with plastic tensonors'. I would think the engineers would learn and go back to gear driven. So with the Trac Im not sure what type of metal. Would make a good tensonor. Ok so I got a little off..:offtopic: [/QUOTE]
