I have the venom onboard temp guage and i am building my buggy right now, i am wondering where to wrap the wire around to get the best reading?

in between the first and second cooling fin on the bottom of the head.

90 degrees from the exhaust port.

I use this on my MT2... Works great within about 5degrees of handheld.... 90 degrees from exhaust port is perfect....make sure the probe is about level or just below level of glow plug........ If its above it... won't read correctly.....
