Hi all just having some issues an cant seem to find the source of the problem as my 2004 Fe450e keeps stalling out after 15 mins or so of riding, then its a pain to start again after that, any ideas be greatly appreciated :)

my 09 450 has done 160 hours, I did all the nessecary work almost exactly as rhe manual says. now, after 30 -45 mins of riding all sorts of trails, the engine wants to stop for no reason, although it occus when i pull the throttle qoute firmly. It feels as if the carb is giving problems, but...

after several hours yesterday and today i got my berg back together. It is now flushed of all the sealant that caused the blockages. It has new C4 stronger main bearings, sprag clutch and had the ok from mechanic. It thankfully spluttered into life this evening. I took it gently 200 yards...
