    The HD Evo 1340 is the new collectible. Rebuild it and keep it.

    If I had an H-D, as soon as the warranty expired
    I’d seriously be looking at S & S
    for gear drive & displacement increase…
    S & S, Nuff Said !!!!

    I’m assuming it’s available in their big bore setup for some “bump” in performance…bigger is better..

    I recently purchased an assembled S&S engine. It has a stock Harley oil pump on it. Make your own decision. ..Z

    Keep your Harley engine. Z

    Guess to who Harley dealers are obliged to send Harley engines needing in need to be rebuilt. To S&S. It says a lot about the expertise of S&S.

    True. Harley-Davidson has an agreement with S&S. All H-D engines are rebuilt by S&S, not by H-D dealers. S&S has a big dept. doing only this for Harley.

    Zipper, did you purchase an engine from us here at S&S or was it assembled by someone else? If you recently purchased an engine from us it would have had an S&S oil pump if it came out of our facility. The only exception is if you purchased one of our SB series engines. If you have any issues with you engine please feel free to call us, we would be more than happy to take care of you 866-244-2673

    My ’91 Evo was one of the famous “bad” cases. After three base gasket replacements I finally found the “infamous” hairline crack at the oil galley (leading to the total launch of many an Evo case). Unfortunately too late for warranty. I opted to rebuild with factory cases (matching #’s). I think it cost me about $1200.00 at the time, and a lot of hours in the garage. If I had to do it again, this would definitely be the way to go. ……………. Dave …………………..

    S&S makes a great product but if you want to keep your bike titled as a Harley, and keep the resale value, you’re better off with Harley cases. Or, set your original HD engine aside for when you do sell the bike.

    I don’t want to say negative things about S&S, there are a lot of nice and talented people who work there. I can only say from 55 years of experience dealing with engines I’ll take bolt on Screaming Eagle kits. Z

    Thanks Kevin!I do like to trade cup/handle patterns where I buy on the pullback (handle) and sell the breakout. But, I would not have traded the pullback in QSFT because of the congestion (ovenlappirg candles) at the pivot point. And the risk/reward was too small.Not sure what you mean by your last question (?)
