have you looked into the clutch basket? They all tend to make this sound after age creeps up on them. Does it make the sounds with the clutch pulled in ? Also I'd like to know how the oil cooler has been working ?
The oil cooler appears to be working fine. I can't tell you how much it has dropped engine heat, but it gives me peace of mind, knowing it is there. I've only ever really worried about engine heat when I have been stuck in traffic on a super hot day, so, when one of those days arises, I now think to myself, well, at least I have the oil cooler to help. No, I haven't looked into the clutch basket. I diagnosed the noise as a loose exhaust header clamp, after making this video, and told Joe Bond about it, replying to his comment on this video.
Thanks for asking, Joe. I'm still trying to figure out what, exactly is going on. It isn't a rod knock. After this video was made, I eventually found a loose header connector, the aluminum piece that locks the header to the head. I tightened it down, and eliminated the "rod knock" noise. It was so loose that it was bouncing around, rhythmically, sounding like a rod knock. Lesson learned: CHECK THE SIMPLE THINGS FIRST! But the original problem still persists, a rattle-ly noise, occasionally (seems to depend on engine temperature???) when applying high load, low RPM (like pulling away from a dead stop.) My first thought was "exhaust leak," and I still think it has to do with the exhaust...but at this point, I have replaced everything from the collector on back...collector and both mufflers. The sound is still there, although it sounds quieter, after the most recent replacement of the left muffler (I originally suspected the connection between the collector and the right muffler). I thought it was either an exhaust leak or a rattle-y baffle. Derek said that he suspected the Intermediate Shaft Damper, or bad primary chain. The ISD is a small rubber part that damps the movement between the engine and the primary drive, that could have gone bad and made the primary chain rattle a=under thouse conditions, Derek is usually right, but I am still not convinced. (The fix involvese splitting the cases,a nd essentially a complete rebuild of the engine). Currently, still riding the bike. I don't think the engine is going to seize, but I am keeping my ears open, trying to figure this MF'er out. Fixing the easy things first, and if I do determine that the damper is to blame, or just get sick of sounding like crap pulling away from every light, I will swap the engine with my spare. I really don't want to do that, but after swapping out most of the exhaust system, I think it may be necessary. Like I say, though, it does sound quieter, now, after the exhaust swap, so maybe it is related. I'my mystified...and still smoking wannabe's when the light turns green...lol Thanks for asking. I think some of this had been recapped on the Yahoo Newsgroup, so there may be more info, there, that I am forgetting to include, at the moment. Regards, Rich
