DR 350se Idle issues

Recommended Posts

my 94 350 is having a hell of a time idling and running.

if I start it, the only way it'll idle is if it's at half-choke. If it's on full choke, it revs really high

at any choke after it warms up, it bogs down immediately, even just breathing on the throttle seemingly 🙄

only indications I have thus far is my F/A mix is backed out 2 1/4 turns, my main is 127.5, pilot is 37.5, the spark plug is a white color (lean), i added an inline fuel filter about a month ago after some gritty shit in the gas tank dumped into the carb (so much for the internal screen), and I haven't touched the needle. Can't remember if I messed with the idle screw or not.

reading around, other people seem to be pointing to 140 for their main jet, even though OEM specifies what I have.

bike ran ok, but it ran good when I was in 8000ft elevation about a month ago, drop down elevation (1,000ft) and now she can barely yank crank.

Thoughts to fix this?

sure, there are dozens of threads about this. read.

Can you please post links? I feel like I've tried everything now that I've read, and it still isn't working. Maybe I'm missing a couple threads you've seen

Sounds like you're running really lean. Does backing the fuel screw make it run better?

Check your airbox cover and if its got a gaping hole tape it over to leave about a 2" square hole.  That will work with standard jetting - before modding a bike always make sure it runs properly as stock.

 

But I suspect you have a blocked pilot jet anyway, classic symptoms - carb off time I'm afraid.
