I ordered the tach that elime linked to on this post: https://tw200forum.com/forum/general-...tml#post647002
Got it installed last night and confirmed everything was good to go.
Install instructions as come with the unit are straight forward.
Simply wrap the end 3-4 times and around the spark plug wire. I secured with a supplied zip tie.sparkplug.JPG
I routed the wire up under the gas tank and secured the bundle to the steering column (name?) tab that sticks out w/ other supplied zip tie.
Connected the unit to the handlebar crossbar and secured with non-supplied zip ties.
Upon complete physical installation, I began the process of programming.
The programming directions are a bit confusing when it comes to settings, if you don't know which one the TW200 uses. The correct setting on the unit for the TW200 is 0.2RPM.
This is accessed by holding down the S1 button until it goes through to 2. Once that shows, release, it will flash and then it sets back to the hours screen.
Use: The unit will start once you start the bike, displaying the RPMs of the engine. Let the engine warm up a little before messing with idle speed. Many factors influence the idle speed, from temperature to altitude, etc.
ETA: Different wire routing after shortening the wire:
Shout out to TDubsKid's video, which I happened upon when looking up idle speed adjustment. He basically went through the same process I went through.
