Question evo engine noise

I have an 883 sporty . I have what I think is exccesive engine noise that increases when the engine warms up. I suspect the lifters. The bike has 8,000 miles on it. I ve tried heavier engine oil but no change. I would hate to have to change them and find no difference after. I was told evo sporties always sing but with hydralic lifters it should be as quiet as a church mouse.

I don't believe Harley engines are "quiet as a church mouse". Some are more quiet than others and of those others, some are very noisy. Sometimes it "is what it is" with the noise!

The whole idea of hydraulic lifters is to take up any valve lash and eliminate valve train noise. Valve lash in an engine with hydraulic lifters should be 0. Therefore no valve tick. My car has hydraulic lifters and their quiet.

I think the whole idea of hydraulic lifters was to eliminate the adjustment of tappets...reduced clatter was just a bonus.

Some Harley engines (with hydraulic lifters) have valve noise, and it drives some guys crazy trying to find the source of the noise. But most stock engines are pretty quiet.

I would expect a Sportster engine to be quieter than a big twin, because the sporty does not have the wacky angles of the pushrods like a big twin.

Is the valve noise new, or has it always done it? 8,000 miles seems like low mileage for a lifter to go bad, but never say never....

Hopefully some Sportster experts will jump in...

I bought it with 7,000 on it . Nothing has changed since I got. I guess I'm just one of those guys that is driven nuts by the noise. It just seems to me that harley has been around a long time and their engines should be perfected by now.

Perfected? No company, be it motorcycle, automobile, aircraft or ship have perfected their engines.

1997 Roadking with less than 8000 miles. Lots more noise than either of my watercooled bikes, including a tick, tick, tick which sounds like a lifter. Noise get less noticeable as the RPM's go up. Drives me nuts!

Earplugs... you can still hear the rumble of the exhaust, but don't hear all the annoying engine noise (or wind noise).

Maybe I used the wrong words. More refined is what I meant. Have you ever wondered why a 1200cc engine only puts out aproximately 65 hp.

You have to admit, Harley's aren't cheap. I think you should get a little more power for money, but don't get me wrong. I enjoy my sporty alot. There is a sort of pride I feel when I ride it . A certain feeling I get I have never got riding all those foreign bikes Iv'e owned in the past.
