Thanks for the props Hawkeye. [img]i/expressions/face-icon-small-smile.gif[/img] The unit we've been running is from Eddie Sanders Racing. (www.esrracing.com) I think that's the site. Whatever you do, skip the Heatseeker unit in the back of Dirtywheels, it does work, but it's a pretty crude piece. There is another electrical gauge...the manufacturer's name escapes me, but folks have had some good luck with them also. One thing nice about the ESR gauge, is each of the pieces are available seperately. Now, if you woof into something sooooo bad that a temp gauge is a crash victim. You, the rider may need more help that the quad and it's temp indicator. [img]i/expressions/face-icon-small-smile.gif[/img]
