Hey guys. Bought a new WR450 a couple weeks ago and it just doesn't start properly if at all. It wants to die all the time if you do start it but will only start with the choke even when hot and sometimes will crank forever and not start. So i decided to pull it apart and do some investigating. Before i go any further i do not want to hear "Take it to your dealer" simple as that. I took care of all the basics. I check the valves, exhaust at .008 and .009 and intakes at .004 across the board, all within spec. I checked and replaced the plug, lots of spark. I did a compression test and only got 46 psi with the throttle wide open. I know of course it has auto decompression but that still seems a little low to start an engine? I did check the auto decomp and seemed to be normal. I then tore the carb apart (my do these things suck compared to my yz250!! ) Check all the jets, the accelerator pump, everything is clear and is like new as it should be. Is there anything obvious i've overlooked? I can start it with an "alternate fuel source" and it then runs fine. It just doesn't want to fire which leans mean towards compression? Any help is appreciated!
