I use the SIP speedo with the sensor on a cylinder stud. (putting it on the plug sucks)

I've got a TrailTech too.. and it's great and very affordable.. You could go directly to TrailTech too.

This one already has a 10mm sensor for a cylinder stud.. or you could use the 14mm sensor for the plug.. but they come lose and can be a bitch to fit..

Cht only,Trail Tech about $28

Just received a reply from koso for digital cht-egt
http://www.kosonorthamerica.com/koso/shop/egt-temps/new-dual-egt-with-rpm-amp-water-temperature-7/
With plug attachment added

I have more info on the way about Digatron DT 33k3,it has cht,egt and tach.With heat warning flashing light,memory that runs on 2-3 AA batteries.

here is my order list:

http://www.aircraftspruce.com/menus/in/westach_egtcht.html

AIRCRAFT SPRUCE. MARY GARCIA
877-477-7823
10-00823 CHT PROBE 14MM M-1000 = 24.55
10-01477 EGT PROBE WELD-ON BOSS = 27.50
10-01408 CHT/EGT 2" ROUND = 99.85
10-01442 7 FT CHT EXTENSION LEAD = 24.50
10-01480 7 FT EGT EXTENSION LEAD = 17.75

air craft quality
vibration resistant
temp compensated

if you want to put the probe on a cylinder stud then you would get a different CHT ring terminal

works great

I used the VDO(part #310 901D) CHT gauge that they sell at VW parts vendors. It is a standard K type thermocouple sensor that when the loop broke off after 2 years I silver soldered the ends back togather and soldered the end to a new loop that goes under the spark plug. If you wanted to mount the sensor under one of the studs than solder the end to a large electrical loop connector of the proper size.
The only hitch with the VDO gauge is that the excess wire can't be cut to lenght and requires the excess wire to be stowed under the fuel tank.

I have a stage 6(koso), a trailtech vapor and the standalone trailtech. I wasn't super impressed with the stage 6 one, readings never really seemed to be accurate. Trailtechs are bullet proof.

A thread in the last 6 months did an actual comparison between all studs and spark plug. Seems like the closest in temperature to the plug was the stud nearest the exhaust port... obvious as soon as someone else pointed it out! I'll try to find the link.

ditto on the SIP combined speedo unit using a stud vs. the plug for the sensor terminal. The Koso 10mm terminals work fine for the stud, putting the terminal under the plug is a lot more hassle. The only issue other than cost is the numbers are hard to see at times depending on the ambient light. The plus is not needing a mounting location, and you get other functions as well.

Anyone know how long the included lead is for the sensor on the trailtech tto cht, I've read you need an extension they sell to reach from the engine through the frame to the headset. They sell 24, 48 and 72 inch extensions. 72 would be rather overkill I'm sure

Don't be a dick baby.

Yes it is the cheep-o trailtec. Thing is dead on. The gauge is not illuminated but I have no problem reading it at night the way I have it setup.

Tire cover is 60's Midland.

On a Vespa, you'll need to buy the 48. On a Lambretta I would use the 24.

I couldn't find the TrailTech anywhere for cheaper than $38.

I did the install of the CHT TrailTech meter on Speed-Kills' Lambretta. I would seriously recommend putting on the spark plug. It isn't that difficult to do and gives the best/fastest results.

Get the black one through Treat. It is pretty trick looking. Wish this would have been available when I bought mine.

Yep. 14mm is for the plug and 10mm would be for a cylinder stud.

Most people round down when talking about something they bought. This makes it seem like a superior deal and makes them feel better about how great a deal they always get. But then they omit stuff like shipping and tax and such and the price is much higher.

The cheapest I found from a reliable source is from Treatland HQ!

Ordering the black trailtech cht with 14mm sensor and 48" extension. I just can't come to drilling into the glovebox to mount a 52mm gauge or mounting something so big in a pod externally, don't need a backlite so I think the trailtech is the best for me.

Personally.. and call me crazy!.. but I think I'd order directly from Trailtech and feel confident that if anything was wrong with it, or I had questions etc etc etc etc.. they'd be able to help.. for the same price... ??? I'd even pay a few dollars more and order direct from the source..
