Well another Loudon practice day got rained out, so the bike's set up for hillclimbs.Raced sunday, got second in the 600 4-stroke class,behind the defending class champ on a 600cc buell blast, and third in the 450cc class behind two very fast RD400s.This motor is awesome, and I haven't even started to play with jetting or gearing yet.Hopefully in May I can get it to the racetrack and get some time on it. To recap; the bike is a 99 YZ400 bought cheap and thrashed last winter.After cleaning,lubing and adjusting everything and replacing some hardware store fasteners, I got some bolt-on swingarm extensions so I could hillclimb it.Next was a set of 17 inch wheels and big brakes for the racetrack.This winter I was gonna freshen up the top end, but way too much time spent reading this forum changed that plan,and destroyed my wallet completely.Now it's got a new 426 crankshaft,trued,balanced and welded by Falicon to the weight of the new piston, a 97mm top end and head porting by Foreward Motion, new stainless valves with 28mm intakes, Hotcams adjustable cams still set at stock timing so far, stock carb with EKP needle, and GYT tapered headpipe with a stock 02 426 muffler that I got for free.One more hillclimb this weekend then I'll change the oil and check the valve clearance,maybe jet a little leaner and see what's next. More later...
