yz400f tranny problems??

2 posts in this topic

i have a yz400f and when you switch gears it doesnt feel like it changes but it does. but the shifter feels like it didnt catch the gear? and i was alos wondering what all is interchangeable on the 426,400, and 450 will the top ends bolt on to my bottom end. i am using a dr.d wet sump how much oil should i use 1 quart? and if the 426 or the 450 top end will bolt on my 400f can i still use my dr.d wet sump?

the 450 top end wont fit, you can put a 426 top end on if you put a 426 crank in. I think you could still use the wet sump with the 426, not sure though.
