Hey all..

I have a 92 1340 EVO. Got it out for the first time this year and rode to work.
On the way to work I heard a tick and figured lifters needed to pump up after sitting all winter. On the way home, noise got louder..more like a "slap". Its coming from the front cylinder. I readjusted the pushrods and the noise is still there. Its quiet when its cold and gets worse as engine gets warm. Cant hear it at idle..starts at around 2500 to 3000 RPM. I thought it was piston slap but does it only when warmed up and not at idle. Does anyone have any other ideas on what this could be before I tear the cylinder off? This all started pretty quickly...oil press is good and tappet screen is clean..just don't know what else it could be...Thanx

 

How many miles on that machine?

The PO had it rebuilt about 6000 mls ago..I put about 1500 miles on myself. It has Edelbrock performer heads..but im not sure about cam, although he did say it was not stock as with the pistons...i was told 10:1....but cant be possitive.
