Motorcycle Repair: Exhaust gas temp on 2000 SV 650, suzuki sv 650, speciality cars

Question
Howdy, my son's got a 2000 SV 650 and I'm messing with the carbs. Being a full time car mechanic (check out my website, just google scottykilmer.com  as one word and you'll see about me) I've got all kinds of tools.  I want to know what exhaust temperature should be read right at the top of the header pipes on this bike. I'm using a raytek top of the line hand lazer guided scanner, which is quite accurate.  I can't get anyone to give me what the general idle header temperature should be. I've got five gas analyzers, and that's all OK. BUT, it's a two into one system, and the front reads a hundred or so degrees hotter than the back at idle.  Do you know if this is normal, and what the normal temp should be at idle? This is a problem I get all the time, even working on my speciality, cars--no one really has good data on temps for just about any part of any machine. Temp guns are great tools, but really someone should write a really good data book and they'd be a hell of a lot better.  Not being a professional bike mechanic, I have no other Suzuki SV 650 to compare temps on. Thanks a lot, hope to hear from you soon.   Scotty Kilmer

Answer
Scotty,
not sure how your scanner reads but
temp near the engine is usually about
800F at idle and 1200F high speed.
It is normal for the rear cylinder
to read cooler because they often
make the fuel mixture richer on the
rear to reduce heat.
Check with Suzuki for a recall on this model
something about an oil plate that is installed
near the rotor to reduce air locks
that restrict oil supply at higher
speeds.
