I have a rattle ( or more accurately a rumble)that is coming from the front of the motor in I believe in the lower end. It has increased in intensity in just the last couple of days. The noise is similar to an out of adjustment primary but I've already checked there. Oh and there is a bit of a whine that increases in pitch with rpm. It does this whether or not the transmission is in gear or the clutch is engaged or disengaged. Any light that can be shed on this is greatly appreciated. Thanx Brian | ||

Very tough to diagnose from a distance. Suggest you have a trusted mechanic diagnose it. Suggest checking the sprocket shaft nut. Torque specs were recently revised upwards by the factory from 190-210 FT*LBs to 240-260 FT*LBs. Clarification! There is not way to actually "check" the torquing of the nut. You'd simply need to remove, clean, loctite, and retorque to new specs. | ||

Brian(AKA Static): WHINE: Check primary chain adjustment(5/8" to 3/4" on the tight spot, adjust to 5/8"  ... OTHER UNKNOWN NOISE: With a very long screw driver, handle to your ear, touch tip to various points where you think the noise is coming from ... If you can pin point the noise point(yes/no) get back with us ... In BUELLing LaFayette | ||

Buellistic Using the screwdriver method, the noise is loudest at the crank case below the forward cylinder, though now the rumble is so loud it drowns out any normal sounds the motor makes. That said, I pulled the drain plug and not surprisingly found the remains of bearings on the magnet and in the filter. So now my only question is what in 26k mi. did I do wrong that may have caused this. ( obviously open to speculation, but I have adhered to " severe service" scheduled maint.) Any ideas? Anyone in Phoenix Az know who to go to for bottom end work and parts? | ||

Brian(AKA Static): You did not answer about the tightness of the PRIMARY CHAIN ??? With remains of bearings on the engine oil drain plug and metal in the filter is a positive indication a very important bearing is bad ... Which one remains to be seen, as in take the primary cover off to check the the engine drive sprocket bearing(WIGGLE TEST) then the cam cover to check the penion shaft bearing(WIGGLE TEST) ... The final check would be to pull the front cylinder to check the front rod(WIGGLE TEST) ... Since you have a 03XB9R with 26K, it is impossible to say if you have done anything to cause this with the information that you have given ??? Do not know how much experaince you have(although your profile says AUTO TECH) to do what will be required ??? My advise would be to take it to a REAL BUELL DEALER, if you have one in your area ??? Remember this: "ONE OF THE MOST DANGEROUS THINGS IN THE WORLD IS A HARLEY-DAVIDSON TECHNICIAN WORKING ON A BUELL!!!" Any of you Phoenix, AZ BUELLers lurking on the BOARD please help Brian out with who is the reliable BUELL DEALER in your area ??? In BUELLing LaFayette | ||

Sorry I forgot to mention the primary chain. It is adjusted to 5/8 @ the tight spot. I tend to keep a close eye on that and even played with the adjustment a bit to see if the whine changed but no change was evident. I'll start with the wiggle test(s)and see what comes up. Thanks Brian | ||

Brian, Ever resolve this? | ||

Sorry I forgot all about this thread. I'll try to make this short. Because I purchased the extended warranty when I got the bike I decided, after checking the pinion shaft bearings, to head to the dealer. The problem appears to be that one of the cam bushings ( cyl#1 intake, I think) backed into the flywheel assembly. Which explained the amount of brass in the filter. A closer look at the particles on the drain plug turned out to be from the oil pump and not the bearings. So to make a long four-month-something story even longer I have a rebuilt engine that was covered by my warranty. The bad news is that this is, apparently, not the only 03 xb9r that Chandler Harley has seen with this problem. At least one other bike was in at the same time with a similar complaint. Thank you all very much for your help. I anyone needs more specific info I'll see what I can dig up. |
