CHT?

I did some research regarding cylinder head temperatures (CHT) for 2T Scooters and found this Info.
Ideal 50 - 60°C / (122 - 140°F) Need to worry +80°C / (+176°F) Way too hot +100°C / (+212°F)
Is this somewhat accurate?

Liquid cooled or air?

Those are all very cold for an air cooled scooter unless you're talking about idle or very low throttle. Most of mine run 200 or less at idle, mid 200s to 300F part throttle (depends just how much throttle.... if I'm at 7/8 it'll run pretty much like WOT), and 320-350 or so WOT. You're prob better off to go through a tuning process and note your CHTs because some gauges/senders don't seem to read the same as others.

The reason why I ask is I need to buy a temp gauge and most of them don't go over 120°C (248°F) So if the BBK runs around 160-176°C (320-350°F) at WOT then most of the gauges are worthless.
I guess a trailtech is the only choice then. Too bad, there are other, more nice looking once but they don't have the same range as the TTO

The Trail Tech temp gauge is a good one. It is pretty affordable. Right around $30. I just installed one a few weeks ago and I love it. The only drawback is you have to purchase an extension lead because the standard leads are way too short. I can't remember how high the gauge will go. I would recommend the 48" extension lead.

Yeah that is what niz76 also said. I was hoping to find a different temp gauge with backlight or something like this www.webike.net/sd/21346159/$30 is reasonable but I don't live in the US so $30 + $8 (for extension) and then + $?? for shipping. And shipping to Japan can be expensive. I will see what I can find in the www. Thanks for all the Info and help. Appreciated.

procon products on ebay has loads of k-type displays and sensors.
I have one from them, whole setup cost $16 (combined shipping) ships from china so should be same price to you.
They shipped wrong sensor and a scratch in the gauge screen at first, but they quickly sent the correct one.
I haven't installed it yet however but I have no doubt it'll do its simple job.

Amazon.com has free shipping on both. The adapter and the actual temp gauge. What I don't know is, does that deal also apply for Japan.

Thanks. I was just looking at their site and I found a K-type CHT sensor with a 10mm I.D. ring and 19" of cable for $6.00 US. Then I found a cool blue led k-type gauge ( temp. range from -200-2300 F) for $14 US. That seems to be a really good deal and the 19" cable should be plenty. This is inexpensive enough to get another probe style and mount it in the CVT case for reading the temps there. Fantastic. Thanks for the info. Bill

I got mine extended from 0.5m to 1.5m for just $1!!

Elektrey:
I measure my spark plug thread diameter at .389". (C7HSA) So I think the 10mm (which is .3937") should fit well. I am thinking I will need more than 19" on the lead now that I thought about it.
I see you got the 14 mm diameter I.D. which is .550" which might fit a little loose around the plug, but, if it works for you...cool. I like the 1.5 meter length, well worth the dollar, ha ha.
I am very glad that you pointed this source out to us. As I said, making a cvt case temp gauge will be easy to do also. Can't have too many gauges right?
Thanks again.
Bill

The 2t scoots take the 14mm spark plug sensor...
