08 540 xc
External: Trx450r bumper adapter with pro armour pumper, Houser XC arms, DWT G2 headlocks, rath billet rear hubs, Precision stabilizer, Teixeira Tech stem and bar mount, fasst flex bars, fourwerx hood, Houser nerf bars, tiexeira tech gusset kit, Honda thumb throttle, IMS tank, fourwerx seat cover, rath Grab bar, blingstar sprocket guard, ricochet skid plate, topar case saver, pro factory clutch cover, KTMBILL exhaust and fuel customs intake, rocket Ron triple rate shocks set up for my liking, 15/38 gearing, Baldwin oil cooler and cooling system mod where right side port is blocked off. Hour meter/RPM gauge and inline coolant temp gauge. Lots of powder coat and some COR motographics to match. I’m sure there’s other stuff I’m forgetting.
Internal (carb):
dual AP nozzle and thumper emulsion tube, quickshot adjustable leak jet, 40.5mm bore
Jetting is: 168 main, 45 pilot, needle is FHM (pretty much an HRC) on the 5th clip from the top. I believe leaks jet is 3/4 turns out.
Internal (engine): built by Jeff at extreme tech ATV, 540 big bore with ceramic coated piston and cylinder, rebuilt crank with welded pin and oil mod, Carrillo rod, I believe a 13:1 JE or CP piston, +1 KW intake and exhaust valves, porting, 8/33 cam, rekluse clutch, that’s as much as I know he did, there maybe things I don’t know about, that’s why I’m unsure about the piston brand and compression.
Made right around 64 with a 42.5mm carb but went down to 40.5 because it was making too much top end power, that was with the stock pipe and HMF slip on. Since adding the carb mods and the KTMBILL exhaust it is making right around 62 and 42 lbs of torque on VP u4.4 fuel, which is what I run, and an o-ring chain. He told me his dyno reads right on, not high or low.
