SV650S Problem???
 

Need help! My son was in a minor accident with his 2001 SV650S. Most damage was to fairing, speedo and lights. I've replaced all the entire fairing, speedo unit, handgrips, radiator, left footpeg/assembly, shift lever, front wheel, both tires, battery, etc. Figured I might as well do things right once I started. I started the bike up last week for the first time in 2 months. I noticed that when I rev the bike to around 3000 RPMs that the exhaust down-tubes off the front cylinder gets red hot (glowing red/orange), back tube also but not as much. I don't remember this happening before, but I might just not have noticed. What could the problem be?? The bike seems to be running fine but don't want to damage anything until I get this fixed if needed. I've checked for airleaks around carbs, intake, etc but can't find anything wrong. Do I need to take this to my mechanic or is this normal??

someone will probably say its because the bike is running either lean or rich (i dont know which one)

its not normal.. they get hot, but shouldnt glow :shock:

As for the cause I have no idea, sorry

I have seen it on the SV before. It shows up more in a garage where there's lower light levels.

There may be something wrong, but I suspect what you're seeing is "normal". It's not nice, but it's the way they are. It's less pronounced if you advance the ignition with a stepped key or slotted pick-up mounts (allegedly! :lol: ).

It is normal, someone asked this question a while back.

Dig through using the search function and you should find something.

In fact, you muppet, we did answer it a while back. I draw your attention to this thread, strangely enough started by you......

I know I did. I just wanted to get some other opinions. I'm still getting mixed answers. Some (like you) say it's normal. Others say it's not. How can I be sure? I don't want to blow the motor or something like that. I just got the fairing/cowls back from the painter and am in the process of installing them. Hopefully everything turns out fine. I'd hate for the $2k I've put into this bike to be for nothing.

I never let my bike idle run on the choke that long, long enough to shut the garage door, put my gloves and lid on.. probably no more than 2 - 3 minutes.

How long are you letting it run at 3000rpm for before you notice the pipes glowing.

It runs at 3000 rpm's for less than 2 minutes before they start glowing orange/red. Choke is not a factor as it is shut off right after starting the engine. It has been garaged and that is where I noticed the glowing.

Well all I can say is that mine doesnt do that.
