| Howdy! Noise from lower left rear. At full throttle, from a stop or 15/20 mph when the bike hits 35 mph there is a short, hard to describe noise. No noise when no full throttle. Is this a case for grabbing the front brake and revving her up, when stopped, of course. Thanks, Paul |

| This (Howling?) noise is something I've grappled with for years, although it was always during take off or crawling in traffic etc. I thought I'd figured it out when I kept finding dirty clutch shoes which I assumed was due to a mixture of different types of grease being used each time the clutch assembly was removed and grease was creeping into places it shouldn't be. When I decided to change the two bearings inside the pulley inner-half, I found this: Bear in mind, this is at ambient temperature and it poured out like thick oil. Anyway, after a strip down, clean up, new bearings, proper grease used in the right quantities as per the FSM, and a rebuild, all was well for a long time. A few weeks ago the howling started again but it was very mild, so, last week I took the clutch assembly off and found everything in order apart from slight glazing on the clutch shoes. I cleaned them up, gave the belt a little brushing to remove any dust, cleaned the pulleys and put it all back together. To my horror, it is now howling rather harshly and is accompanied by a slight squeal. The squeal is probably the belt but the howling has got me mystified once again. I'm going to have another look this week but I can't imagine finding any wrong in there. BTW, gustav, this type of problem is covered elsewhere on the forum so a search might help with your particular problem. |

| Yup, I've searched other threads. Kind of annoying, but I'm not really worried about it. I have a O.E.M. belt for when I reach 13,000 miles. Thanks, Paul |

| Ditto. It's a bit like an itch you can't scratch. Nothing wrong but just a bit irritating!

| Hi folks.
Have you checked or tested the Swinging arm drive belt outer cover rear bearing? I used a snub nose polishing wheel in a drill stuffed into the bearing inner once the case is off to run it up for noise.
Hope this helps. |

| Thanks JohnyC. It runs smoothly using a finger and there doesn't seem to be any movement, but I'll try your suggestion. |
