it might be worth it if you want to sink money into it, they are great bikes if you take care of them, as in keep the valves adjusted. i have one and its great, lots of power and speed. its just a little on the heavy side compared to the new 450's.
not hard to start anymore. i fixed the problem by putting a hot cam with auto decompression in it. it starts as easy as my boys kx 65 now and run likes a raped demon.
i just bought 01 yzf 426 dirt bike and i am having trouble getting it to start when hot or cold. it has flat top piston, short rod, white bros full exhaust and diferent intake. is there any parts out there to make it start easier without have to roll start it. even when i use the hot start is almost kills me to turn it over.
