My brother Kenny was supposed to rent a TAG ride from LAD at M-O last month and was told he would have to adjust the exhaust valve/disc???? He didn’t get to run the kart because it rained but I’m sure someone will be able to shed some light on this for you……err…for Dave!
Yep, it’s for Dave! He said that with the new Evo kit there is no adjusting of the power valve. It’s automatic adjusted through the new kit and depends on how you have that ground wire attached (on or off).
And yes, that was a bummer that your brother couldn’t run the kart at M-O. It was REALLY slick, so I can understand why they wouldn’t want it on the track.
