Laser thermometers are now cheap enough that they m,ake a VERY useful addition to your tool box ( also useful for making sure you Champagne/beer is cold enough).
Our little Suzi is notorious for single cyl running ( I don't love these carbs but other things can crop up). It can be notoriously difficult to tell if both cyl are running properly.  If you take a reading on the exhaust pipe at a common distance from the head it will tell you much.  Both pipe should be pretty close to EXACTLY the same temperature. If not you have a problem. The thermometers are accurate and fast enough to even give you an idea at various throttle openings under load if you can put it on a dyno and at idle they are brilliant for helping get you initial balance and pilot screw settings( notoriously difficult on anything more than a single.

Just a little note that may help some people with some of the suzi's problems.

Interesting--it sure beats grabbing exhaust pipes. I'll have to check out the prices.

heck yes!  ive had mine for years.  super useful for all kinds of stuff.

Just bought one for my toolbox - found a cheapie with great reviews on Amazon.
