AEM 30-0300 X-Series Wideband UEGO AFR Sensor Controller Gauge
The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) features a modern, visually striking faceplate and new seven-segment center display that is 87% larger than the 30-4110 AEMThe gauge includes a 0-5v and RS232 serial port output for feedback control and data logging, and an AEMnet (CANbus) output for data loggingX-Digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating conditionFaster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tuneWhen tuning an engine using wide-band AFR feedback control on an inertia dyno, dead time affects the data you are looking at because it is reported in a different operating location than when it actually occurred

The big engine performance step up from where you are at now is a pair of Mikuni VM series smoothbore carbs which last I heard are available in kit form for that bike, combined with a good set of pipes.

Read the fine print as there's another variant of this same kit for some of the 360s.

On pipes, I'm a big fan of adapting certain generic supertrapp mufflers meant for small race cars and go karts to our bikes because you can tune the airflow at the pipe as well as at the carb. Start here:

Don't order anything from there until you have a good 2 into 1 header pipe already because you need to know the outlet diameter you'll end up with on the other end of a 2 into 1 merge. Yes, you want a two into one pipe for sure.

If you really truly know shit want to do it right and get it dialed in exactly, when you build the pipe set up drill a hole just downstream of the merge point and cap it with a nut of the correct size the hold the sensor for this critter:

This bad boy will tell you your exact fuel-air mixture and completely eliminate guesswork in carb and pipe tuning. The only problem is, permanently mounting it is a bitch because you cannot shorten any of the cables between that Bosch sensor and the gauge, and they come long enough for a car. Oops. That's okay, you really only need it during the tuning phase. Once you're done take it off and screw a bolt into the nut you've welded into the exhaust that's the same thread pitch as the Bosch exhaust gas sensor.

These things completely revolutionized carb tuning and I did not know about them when I wrote this:

On suspension, rims and handling issues I'm going to refer you to that document. I'll be happy to answer questions.

Short form, you could do a hell of a lot and still keep it vintage-looking by using forks from a bigger bike of approximately the same era and technology, but also make sure those bigger forks can take cartridge emulator inserts internally. Add some decent rear shocks as well, make sure the swingarm pivot bushings are in good shape, put aluminum hoop over spoke rims fore and aft and you'll have something that can be tossed hard into an extremely twisty road and even beat some guy on a modern sport bike who can't use all his horsepower cuz it's too twisty. You'll have one big advantage if that thing is built up right: you'll be able to flop it in and out of corners faster because you'll have less gyroscopic effect off of light thin rims.

ROFL. Bad advice day? "Most carb guys don't use any of that." Obviously someone has never been around people setting up high horsepower carbed engines. The only part I see these guys tune by ear is idle, part throttle and full throttle get the gauge.

OP, you're looking for an AEM UEGO Wideband. They're like $200. The new X-Series are awesome.
