Sled has 1300 miles. RPM flares to 8100-8200 at low to medium speed when WOT. As speed climbs, rpms settle to 7900 when -25 out, in temps just above freezing, it bogs all the way down to 7500. New plugs, deflection set, all codes cleared, clicker set on #5 (was worse on #4).
Going back to the dealer Monday. Is there a simple change to clutching to resolve this perhaps? Maybe a primary spring with same preload and higher rate / finishing load? Is anyone else experiencing RPM fade as the belt / ambient temps warm up? Belt life so far is good, belt in good shape.
In cold temps the sled pulls 7900-8000 and runs 102mph on the dash, as it warms up outside & belt temps, it runs 7500 and 88mph.
