Unhappy my drz400 won't start, i just did a tune up, whats wrong?

so i tuned the bike up.. changing the spark plugs, oil change, cleaned the carbs, cleaned the air filter...

the bike would crank and start up for a lil bit, and it would just die out suddenly.. like it would just die out when i'm riding and then after that; sometimes it would start up again, and sometimes it don't.. and usually wen i start it up, i have to pull the choke out to start it, den push the choke back for it to keep idlying..

what could be the problem? Anybody else with a drz 400 too that knows?

Turning the petcock to 'prime' next time it happens would verify that as the culprit wouldn't it?

yeah... sounds like the vac line from the petcock to me... put it on prime, and see if it runs... its really easy to overlook that line... i know from experience.

If your DRZ sputters on idle, even with the choke out, and then eventually dies with a twist of the throttle, most likely the vent hose that connects to the port on the underside of the OEM tank isn't connected or is pinched.

If your bike dies while you're riding it, then most likely the skinny vacuum hose (right behind the fuel line) is pinched/kinked where it connects to the petcock. A longer hose (cost is less than a buck) fixes the engine shut off problem.

Check these two hoses before you tear open your carb.

i tried checking these two just right now, they both look clean tho, but i'll go ahead and try to change to a longer hose then.. anyway, a friend of mine said it might be that i need a tune up on the carb or adjusting it somehow...do you agree ?

If it ran before the tune up and not after, look for something you left unconnected (sparkplug, leads, hoses, vents) or accidentally disconnected. It's not likely the carb suddenly needs cleaning because you tuned the bike.
