Hi everyone! After a long time lurking and getting a ton of useful information, I decided to join the forum. I have been wanting to put a dirt bike together for a long time. The last bike I owned was an 89 YZ250 and I had a blast on it. A buddy of mine knew I was tentatively looking for a new project and had an 01 YZ426F he had left at the bike shop to be repaired due to grenading the motor. He got tired waiting for the shop to get to it so he picked up and locked it in the garage to live (kinda) the rest of its days. He sold the bike to me for $400 which I felt was more than fair and he needed the money. I know the parts will add up but I like bringing old machines back to life and enjoying them. So I picked up the bike today and it was actually in pretty good shape! My wife and had a joke that I was buying a motorcycle in a box (which was partly true). I pulled the head and cylinder off and just as suspected the cam appeared to have skipped a tooth sending the valves into the piston. Luckily when the engine failure happened it didn't totally lock up and he was able to shut it down. I pulled the valves out and a couple were bent. The good news on the head is there was no damage to the head itself! The seats look perfect! Also the cams were replaced with the auto decompression setup so that's nice. The cylinder and piston are total losses... I pretty much expected this (and much worse) when I heard the term "grenaded the engine." The connecting rod is bent but it amazingly did not damage the case thank goodness! I checked the movement in the crank itself and it feels good. No up and down play and only a little side to side play. So here's my plan so far: I am going to replace all of the valves, springs and valve stem guides. One question I have is I know the 01 came with factory factory titanium valves but would be alright to run stainless due to being a fraction of the cost. I understand I might lose some response because of the heavier material but I'm not racing or anything and this bike will most likely have more than enough power and responce for me. I am going to try to pick a good jug that I can just run a hone through and a new OEM piston. For the bottom end I'm thinking about buying a new connecting rod kit and having the machine shop set it up for me. I know this project is going to cost some money but I am going to spread it out over time. I think the bike is worth it and will be a fun ride to just put around on. Besides my son loves helping me out! He's helped me build from the groun up a couple old waverunners and an 80 Arctic Cat sled. I really look forward to showing my progress on this forum! Thanks for your help in advance!
