Check your speedometer cable. If you don't regularly lubricate it it can rust and break eventually. There should be a cable running from the front tire near the axle up to the back of the speedometer assembly. Inspect it for damage.

Usually the speed sensor is on the gearbox's carter. If the bike has abs than probaly the speed is readed by the abs sensor.
Those are general informations, not special for you bike.

The colour codes are usually on a sticker or label attached to the frame, somewhere (generally bike is stripped of painted parts to find this info)....they are also usually printed on the info/specs page of the owner's handbook.
The link below should provide you with correct information you're after however, cheers!

There is a neutral switch and starter circuit relay that disables the CDI module and prevents the starter solenoid from energizing.

Likely your start switch bypass attempt at the solenoid didn't account for the the CDI being disabled, so crank no spark.

You will need to verify operation of the neutral switch and the start circuit relay.

Do an internet search for "ttr225 wiring diagram" if you need a schematic.

I remember these lightweight steeds that had an almost cult following in the UK, resulting in a large number of tuning parts becoming available at reasonable prices.
The noise of a gaggle of them pulling away from the lights all at once could and did break the windows of nearby houses.

The compression pressure of an exhaust tuned 2-stroke engine is necessarily quite low - because the cylinder capacity and the compression ratio "grows" at the rpm the reflected exhaust pressure wave effectively blocks the exhaust port and the engine power suddenly increases. Yamaha engines of that time were notoriously "sudden"...

I don't know the exact compression pressure but I would be happy if I did a test and achieved around 100 psi. My Suzuki of a similar design produced 105 psi on the kick starter. Much more pressure than that and there would be a danger of the fuel detonating in the cylinder when the engine "was on the port", usually resulting in a hole melted in a piston.
