2007 Suzuki Z90 - Will Not Idle


Recommended Posts

I just purchased a 2007 Z90 and it runs great but wont sit there and idle. If I barely give hold the throttle it will idle pretty smooth. I dont see any adjustment so I have no idea where to start looking for the problem. I checked spark plug already. Ive never had anything with no carb adjustments (or I cant find them)

Crazy, I went to the dealer and they dont make a carb kit for this one. Bought one for 25$ for my Yamaha Grizzly 80 .. This one cost me over $30 just for a throttle stop screw. They wanted another 27$ for the float needle alone!!

Another question is. The needle jet below the main jet looks like a pressed fit. Which way do I knock it out. The hole on top side looks smaller than the bottom of the jet but the bottom looks larger than the threads would allow for it to be knocked out that way. Im not at all familiar with this style of carb and dont want to do more damage than good. Seeing as how a new carb runs over $300. I dont understand how the choke works on this thing either.

on page 4-5 in the manual is the carburetor blowout. all the jets unscrew. the choke looks like a regular push/pull set up, other than the fact it has a handle like an old well water pump. does this one work the same way ~ up and down motion to prime it? or just a toggle type setting?

sucks the dealer didnt have a kit, they sure gouge you for individual parts ...
