I've been haunting these boards. Looking for a bike to chase the kids around. NO dirtbike experience. I have been leaning towards a 650r because I'm fat 260lbs and 6'. Hadn't considered Yamaha so far because we've had success with Honda. (Be patient) Came across a 2001 yz426f. It looks in good shape (in pics), maybe 200 hours (50 hours in the last two years by current owner), Pro action forks, damper, new chain, new plug, new break away controls, synthetic oil every other ride. Set up for a 160 lb rider. Current owner checked valves once and they were in spec. Other wise stock. I'll be honest, I'm looking at price, he wants 1900.00. Been reading very good things about the Yamaha. I'm not a maintenance freak; change oil, clean air filter, will check valves, but I want to ride. Not aggressively, no jumps, mostly trails, some open areas. Will it haul me around on the stock springs? Can they be adjusted to somewhat handle my weight? Does a "new plug" signify a jetting problem? New brake away controls maybe the bike was dumped? Am I looking at engine work in the near future with 200 hrs on the engine? Will the bike need a tear down and relube? Any thoughts appreciated.
