old 85 evo question
Hey y'll. I have had my 1985 evo flhtc for about 2 months now and hear a noise in the front of the motor on the right side. It sounds like play in the lifters or something. The thing is I hear the same noise on my 2003 flhtchu/I. I have it about two weeks. The noise is the same just not as loud in the 03. It may be the way Harleys sound being these are my first. I run 20w50 synthetic screaming eagle in the 85 and dyno 20w50 in 03. Any ideas and if I am just looking for problems than just say so because I am good for that!

the evo is built for dyno oil- the gaskets may start weeping your synthetic.
if so, just drain it and swap to HD 360 20w50.
you could get the noise listened to by someone experienced with evos.
guessing from my sofa could send you off on a goose chase.
some riders had lifter failure at 40K or so.
both my evos ran up over 75K on the original lifters...both with cams.
if you have adjustable pushrods, get a tech to give them a quick spin- an experienced hand can tell alot.
BTW there is a great evo section on these forums

Evo are notorious for lifter failure but Mike is correct. ..do NOT rely on Internet diagnoses! Get it to an indy you trust...my Evo had a lifter go out at 25K...on a road trip...In Grand Junction...it was ugly...
