Hi I had bearing knock noise in my 92 sportster after about 5k miles driving it (I bought the old relic used with 20k miles on it). So I parked it in the garage and bought a 99 S3 with 15k miles on it and now after 8 months and 6000 miles, knock knock. Is this bad design, bad luck or bad clutch technique? It seems like a replacing a crank bearings takes so much skill that i would never get it right. Any newbies like me ever try this and get their bikes back on the road? Thanks for your replies. | ||

That's very early for rods to be knocking. I beat the snot out of my S1 for over 19K (bought used with 3k miles) and if the flywheels didn't shift slightly she'd still be running strong. Check the engine sprocket nut first and torque to the new specs (with a new nut). It sounds very similar to rod knock. If either happened to both bikes you have some very bad luck! Crank bearings/truing isn't too difficult. Obtaining the tools and fixtures necessary for the job is. I'd suggest getting someone with experience to help. I replaced my crank with a '00-up Buell crank (requires some case machining). It's a better, theoretically stronger design, but is expensive. S&S is another option. Check a couple of the sponsors for prices/options on crank rebuilding. |
