How safe/reliable is it to raise the limit that much without valves/springs/retainers?
@Superpacman13 I noticed the new valve kit, any chance of a valvespring combo?
What about spark and up rated fuel pressure regulator? I’ve already got a Ti header and midpipe, want to upgrade the filter and airbox lid, but what’s the point without upgrading fuel/spark?
Leaning toward the RBE myself, but haven’t gotten confirmation that there aren’t any surprise compatibility issues with the Husky pilens. (I’ve got a ’21 Vitpilen)
Has anyone done a back to back comparison? I’m expecting my build to be pretty extensive if I can ever source an upgraded valvetrain...
Has anyone gotten any response from @cjwell? I’d like to start a 390 build on my 2021 Husqvarna Vitpilen 401, but it looks like support for the 390 platform has dried up. No Valvetrain kits, aftermarket Cams, Big Bore pistons, little interest from ECU companies in testing Husqvarna support…
