Ok, just got a '00 WR400 that I'm planning on converting to sumo duty. The bike has sat for at least 1.5-2yrs without ever starting. I ran fresh gas through it, with some carb/injector cleaner. (the old gas wasn't even flammable anymore. ) Here's the symptoms, hoping someone could point me in the right direction before I start off like a blind rat in a maze: Cold: Bike will not start with choke out, only with choke in. Then bike will not stay running unless choke is pulled out. Hot: Bike will not start with choke out, same as above, but occasionally pulling the hot-start out will aid in quicker re-starting. So basically the bike will start but then needs the choke to stay running even when the bike is warmed up. The bike is bone stock, with the exception that the cap on the end of the stock muffler has been removed. (guy must have thought it was ohh so "cool" to be able to make that noise:bonk: ) Is there a baseline that I should be working from as far as needle height/jet selection? I know that I need to take the entire carb apart and thoroughly clean everything. I'm worried that this guy got advise to "get a jet kit" since he removed the silencer plug, and muddled everything up, especially since there's notes in the jetting section of the service manual....all chicken scratch mumbo jumbo..... I plan on doing the throttle stop/grey wire mods eventually, but would like it to be reliably starting first, and then work from there.
