Hey had my 650 out on the weekend and was running great till she lost all her power! changed plugs, checked spark, but all was good! after i got it started, you had to hold the throttle all the way to the bar once it was running just to keep it ideling. as soon as you let go, it would die! Its almost like she wasnt getting fuel, but she ran great for the 45 miles before that happened. and ran great every ride before. any ideas what this could be? or what to check?
thanks

check compression

yes will do that tonight! but forgot to mention that gas didnt seem to be flowing to the pump, as the line was empty and when i got gas back in there, it bubbled for a long time! not sure if this is related or not!
thanks

so checked the compression last night and found 0 in the center cylinder! shitty, guess its time for a tear down! and idea why gas wouldnt be getting sucked up to the fuel pump tho? are the two related?
thanks
