Great post, the 426 is a great bike. Here's my 2000 YZ426 I have owned since new and turned into a dual sport bike, by the way over 500 hours, just replaced valves for the first time and piston and rings. Riders tell me how expensive 4 strokes are to maintain, this bike is on its original crank, and on its 4th hour meter.
Yes! I like to hear that!
Anything over the weekend rbi?
Not too much! I was trying to recover from my travels, picked up a slight cold....yuk. But I am building momentum for another update!
The fill side rad from Myler's came back, it looks good. The carb from Zip Ty Racing should be here tomorrow along with some other goodies. New clutch mount and cable, new throttle cable, head gasket, and some hardware.
I started the timing chain replacement but that ended up turning into an ordeal. In short I had to pull the head. That's why I ordered the head gasket.
I pulled the plug to make the engine easy to turn over. When I saw the plug, I knew a ton of dirt had just dropped into the cylinder. ( should have checked/blown it out )
I am glad I did because there was a pile of dirt sitting on top of the piston.
Also, I decided to clean the head and camshafts as a bit of dust was on them from banging around in the shed.
Will post pictures and update later this week
