Hey REVO6969,

How much over 250? Traxxas recommends 220 - 270. However, to adjust your LSN follow these steps:

a lean low speed needle will most definitly cause high temps.
richen the low speed and kick up the idle a bit and then see if it gets better.

Timjs, I'll Give It A Try, I Like To Try And Get Good Performance Out Of The Engine And Have The Temps A Little Low, The Reason Is That During A Main When The Tank Gets Low The Temps Shoot Up To 260-280 And I Dont Really Like To Run That Hot, I Smoked An Engine After 3 Gallons Running Hot, Had Good Smoke, High Temps, Then Snap Went The Conn Rod. Thats Why I Would Like To Get Good Performance And Keep The Engine Around 220, I'll Put The Lsn Back To Factory Setting And Try That. Thanks
