EGT for tuning

[kkzxxx]

When i bought my scooter the 1st thing i did was to install EGT sensor, its mostly used on karts, snowmobiles, dirtbikes and tuned cars but hardly ever used on 2t scooter tuning, why?
I would think that constantly fixing seized engines sure costs more than 25$ on EGT probe & gauge.

Its great for tuning but will also warn you when you have developed some air leak that will seize the engine.
Yea you can tune by looking at the plugs, but in my experience, you just cant trust plugs, ive done test runs and the plug looks fine but the EGT tells different.


this is what i use:

Installing is simple too.Just drill a hole in the exhaust, about 4" away from the cylinder, weld a piece of small pipe on the hole, then thread the pipe so EGT will screw in and then place the gauge somewhere.
EGT should be aimed at 600ºC(1112.0ºF) , anything over 650ºC(1202.0ºF) will get you a new piston.

Trust the plug , they have been talking to us for over 100 years.

Nice. Haven't seen many people running EGTs on scoots. Most of us have CHTs. I like having something that I can look down at and get an idea of what's up even if something strange happens on the road. For example... "Feels like it's running lean now." Look down at elevated CHT and verify. Can't really do that with a plug so easy.

You young guys & your gadgets! kinda cool bling  to have on  scoot handlebars

I need to make friends with someone who can weld...

I was looking into something like this to give readings on engine:

APSX D2 Digital Wideband O2 Air Fuel Ratio (AFR) Complete Controller Gauge Kit

Any cons to these?

Don't know about that particular unit, but I've been pleased with the wideband on my TaoTao. When I first used it I tuned how I normally would anyway, but recorded air/fuel ratios along with the jetting, speed, and RPM. That way I could kinda check if it's giving me numbers I'd expect.

The O2 protrudes so much, at least on my 50, that it would block most of the pipe off with a standard bung. They don't show a bung in that listing, but you may wanna pick up one a bit longer than normal.

That's exactly what I had in mind.
