So i have a 2006 WR450F.
it was having trouble starting and staying running a wile back. and it now will not start at all (but it will crank)
So its basically been sitting idle for the better part of 3 years. and i will admit when i got it i was new to bikes,..... and i know i didn't winterize it or maintain it like i should have.
here is where i'm at with my trouble shooting, the plug that was in it was all kinds of dry black, and i have a new spark plug, i do have spark when i ground it to the block and hit the e-start.
i cleaned the carbs out before winter and they could probably be done again but i did have it start and run for short time before it would die after i cleaned them. and the carb is getting fuel it drains fuel if i open the drain on bottom of carb
the air filter is dirty but i'm sure there is worse and i will be getting a new filter. (but pulling filter and trying to start didnt help)
also i tossed the compression tester on and the first time when i kicked it over it stopped at 60psi. and then when i tried a second time with the e-start it only got up to maybe just over 30psi. i tried putting a little bit of oil in to see if it would bring the psi up.... and it wouldn't even go up to the 60 i got first. (i would do it wile its hot but i cant get it to turn over.
so. im a little lost in what to do. i can pull my carbs and clean them again (really good) and toss a new filter on but i have a feeling the filter isnt the problem.
also the fuel hoses are a little harder then id like them to be but i dont want to go and order up new everything until i find the problem
top end rebuild? valve problems?
any help would be great id like to actually ride the thing this year.
