sheetiron this weekend

I was just at a friends who has a KLR with about 50,000 miles (mine has 53,500). His engine was making a rattling racket so he removed the flywheel and checked the balancer chain. The chain was out of spec so he is replacing it. He also noticed the gear/ sprocket with the weight on it was very loose on the shaft (that goes through to the other side fro the water pump impeller). He is replacing both the shaft and the gear / weight. The rubber cushion on that gear was starting to tear up. Sobering news for all us high milage KLR's. Criswell

However, there are certain items that have known replacement intervals. What I do know (the known, known) Many aviation components have a known hour or cycle interval for replacement. Historically, many/most aircraft piston engines 'fail' within 10% of their TBO =time between overhauls. Jet engines fail in the hot section, not after hours, but intervals or start cycles. (think cold to hot expansions) =ambient to +500C in 60 secs. Thou shall not exceed the manufactures hour limits on a rotor blade lest thou dash thy foot/face/body into the earth unexpectedly; etc. That said, is there a 'known' replacement interval for the internal chains? I think it would be 'stretch' (no manual handy to confirm) that limits chain life. or perhaps, you might think there should be a mileage based replacement limit based on your present observation. Others here have reported exceeding 60, 70, 80K miles without replacing the internal chains....shrug. Class--what say you? revmaaatin. who would like to know, what happened to the sun. I prep the bikes and it is STILL sub 40F, even as I speak. I thinkk the Leftt Coastt guys mustt be hording the sunshine....

Charlie, I 'hear' you. smile. However, chain noise is subjective, and the older you get the less noise you will hear. shrug. If you have a metal skid plate, you get a LOT more reflective noise vs using a plastic skid plate or riding sans-skid plate. IRT to the metal skid plate, some 'authors' claim higher engine temps as the metal skid plate reflects heat as well as noise. What will really be of interest, if the torsion spring/dohickey adds life to the balancer chain. Which reminds me/us, I need to do a dohickey-adjustment to start off the riding season. revmaaatin.

"When it starts to make too much noise..." Good luck with that. They always make too much noise! That is why I usually wear earplugs and mine hasn't blown up yet! Jeffrey #3

Hi all, I'm going to be at the Sheetiron 300 this weekend. Feel free to grab me and say hi if you're there. It'd be good to meet people from this list in person. I'm on a green 2008, wearing a silver Arai helmet. Daniel
