450cc karting parts

I'm looking to build a 450 CC kart with the motor out of my Suzuki ltr 450, are there any websites that I can find parts to build this setup. Motor mounts, gears, hubs, etc. Thanks in advance
Find a fabrication metal shop to make a custom motor mount. Also radiator mount . All the linkage and shifter clutch handle and bump shift and axle hubs QRC will have that. Just remember to go to stiffer axle say 40 mm or 50mm that is what I am using on my KTM450 with 4 bearings , only because my shifter Trackmagic Diablo came that way. But you can get by with 3 bearings,
