My names Brandon, and I have a 04 250 trailblazer, and it seems to have problem after problem. A couple of weeks ago, I had it out riding, and noticed it feeling hot so I parked it and It started smoking so I just left it alone and thought maybe wasn't enough oil in gas ( Have to mix self because doesn't have oil pump anymore) so went and got more gas next day and made sure oil levels were right, and it cranked up fine, but kept wanted to die down like no gas was getting to it, so warmed it up and got out on the trail and it just suddenly died down and shut off. Ever sense then wont crank back up, sounds like its not getting fire. Spark is good btw. Any ideas??

 

Do a compression check. If it's around 110 psi or lower,probably time to check the engine out. If compression is good,could be as simple as trash/dirt in the carb,time for a new carb kit.

 

welcome to the forum. sounds like the bike was running extremly lean(lack of gas) if it was that hot, so i also would do a compression test and as mentioned it needs to be that high. how does the spark plug look when you took it out? is it white in color or worse it has little particals stuck to it like metal from a melted piston(happens when they run real lean for awhile)? if compression is good then most likely the carb needs to be cleaned from being dirty or having bad gas.
