One Carb Richer than the other?

[High0ctane]

Okay so I jetted my banshee for cold temps, about -25 deg C. I have T5's, durablue filter, no more small snorkel that goes from the box up in front the seat. I was jetted 300 for the summer, and when i checked my plugs i was lean. So i saw the guy who had it before me had 330 jets for the winters, so i try that on and change the plugs, go beat the hell out of it, check my plugs and i have one carb a bit leaner than the other...wtf?

1 side might be leeking?do a leek down test,the best way to stop guessing.also make sure your carbs are opening all the way evenly,and make sure your reeds are in good shape........idle screw check that as well..... :thumbsup: :thumbsup:

Yeah, you might pick up a carb synch tool, or check for leaks with some starting fluid around all the areas where leaking could occur. But you definately want to figure out the difference in flow problem, before it causes damage.............

Found the problem, one carb was sucking air through a hose that had no clamp.

 

I had another jetting problem that I resolved, I had jetted my carbs at 300 at -25

I'd leave the cover off even in the summer. If you can't and go through a lot of mud, then cut the last 1.5" off the end of the lid right behind the clips so you still have all four clips. This will give you another 4hp....Just remember to go up a couple of sizes on the mains when the temps drop to -25 again.
