1997 S3T hasn't been sounding or running smooth as of late. If you've seen my other posts I've been fixing little things here and there on my aging bike so this is next in the series of issues I've been having. Anyway, got home from work, pulled into the garage and cranked the throttle a bit (around 2k) to listen for some of the rattles. After a few seconds, the front exhaust was glowing bright ride. I've never seen it do this before. The rear exhaust seems to be just fine. My guess is overheating due to something, but what? Any ideas? Thanks. -Br- | ||

Bad EXHAUST GASKET front head exhaust port/header ... PM me and "i" will send you the HELP "INFO" to correct this ... | ||

No airflow and revving in place can get that header to glow. I can't explain the physics behind it, but it's been explained to me as well that the 45-degree, common crank pin and single intake tract of these engines will cause the front cylinder to run hotter than the rear when there's no airflow. That said, I'd take heed to Buellestics advice- check the exhaust port gasket, and I'd think the intake gasket on that cylinder as well just to be sure. | ||

The whole reason I even attempted a rev in place is due to a sound kind of like a loose plastic body part smacking against something. But it seems to be coming from the engine or under it. -Br- | ||

They glow if you rev stationary, or leave them idle for a long time. | ||

Brscott, Could it be your tank flopping around? Mine did that until I slipped a strip of nylon webbing under the catch. | ||

I've never seen mine glow even after a few minutes of idling at 100+ temperatures. Of course I never tried that in the middle of the night with the garage lights off.... | ||

@Kalali: lol, I had the garage light on and it was only 70 degrees outside. Anyway, I hadn't revved it more than maybe 20 seconds and no higher than 2.5K RPM. @Ft_bstrd: Sound seems to be coming from further down. I just had the tank off and there is already a piece of nylon strap from the tank map under the catch. I had suspected the shock or component was loose, but doesn't seem to be it. @Buellistic: I'll pursue the exhaust port gaskets after I'm done putting my Tour Glide back together. Though HD is really gouging on the prices at $7.00 EACH! Hopefully the sound isn't coming from inside the engine and is not related to the glowing header. But it is not a sound I've heard an engine make before. Last time I heard this sound was when the front fender mount broke, leaving part of the fender to clatter away. BTW, it is only audible around 2.2k RPM. -Br- |
