    Really like the videos ! This last one just motivated me to what I've got to do on my old xr 600 - havn't kick started it in 12 years , and the engine is locked . Daily use is 99 CB599 , really smooth shifting , quick when needed / some times H.D. Sportster , but most fun and true biking is always the dirt bike . Damn missing it to ! Going to start working on it right now thanks to this guy . 💪

    You need to be at top dead center there should be 2 plastic screws on the side of one of your side covers where you put it at top dead center, the bottom one has a bolt for a socket, and the top one shows your flywheel and your stator, there is 1 mark on the flywheel and 1 mark on the stator, align those up and your at top dead center, never mess with valve adjustments or try and get your cams in time without making sure your piston is at top dead center!!!!!! Very very very important!!!!

So one thing Im confused about is the header pipe gos right into the engine theres no coupler that comes out. Not sure of the name of the part but I see it on all these bikes and mine dont have one. Never worked on 4 stroke bikes so just learning. Thats for putting out these videos they help alot. Just dont know if I should sell as is or sink more money?

    I know this is 7 years ago, but I have a 2002 yamaha yz426f that I tried bump starting it after I couldn’t get it to start even after I did the whole procedure. And now I have really low compression to the point where I can move my kick start all the way with my hand. I used the decompression lever while I dumped the clutch and I thing I might’ve holded it too long. Now the decompression lever won’t engage, the handle is really stiff.

    FrassonRacing yea dude your right but stuck open valve isnt really the right terminology, there's supposed to be a small space between the lobes and buckets, as the space becomes thinner and thinner the cam without the lobe facing down pushing the bucket open will open the the valve ever so slightly causing the compression to escape through the little space between the valve and the head

I put new piston rings and head gaskets along with a timing chain, because when I started it one day it blew out black and bluish smoke so I shut it down and never started again. After I rebuilt it she still has no comp. Going to resleeve the cylinder and put a new piston in it but if that's the case then I wasted my money lmao
