2013 KTM 450 xcf with thumper 590 mod engine. Lighten and balanced 500 crank . 14-1 piston and Thrumper racing cylinder, perf cam and springs, bored throttle body, vortex ignition, pro circuit pipe, 6 speed conversion, and lots of new parts. Low hours since rebuild but on 4th oil change finding alum on long oil screen. Bike runs stong and sounds good. Converted my 2021 450xc to track kit. Not sure where alum is coming from or if its going to be a problem. Previous oil charges screens were clean. $7000 cnd. $5200 us.
