Anyone here use a Millennium Tech big bore kit on their KTM? Did you like it? Was originally going to get a 300 sxs kit, had one on my 2012, until I came across Millennium's site and what they have to offer. Just look for some feedback. Thanks.

Fitted the cylinderworks kits to my friends bikes - a Husky 250f and a Honda CRF250. Both bikes run great, and are noticeably more powerful than stock. I’d recommend pairing the big bore kit with a vortex ECU though. The Husqvarna:Photo

Although I think you might mean two stroke...

Would help if I actually put the bike I'm taking about. Yes, it's a 2016 250sx. Had a 300 kit on my 2012 250sx and liked it but heard millennium tech is doing big bore kits, along with porting, head work and was wondering if anyone had any feedback.

Curious about this too. I've considered a 300 kit before, but not at the cost of losing top end/over rev
