Bike is starting to pop (back fire) a little

had the Yosh and new jettiung for about 4 months now. all is good but just in the last 3 rides. i hear more poping when I accererate and then back off on the throtlle quickly... like up I power 3/4 throttle up a short hill and oh here comes a qucik down hill rut, so i back off the throttle quickly and pop pop two back fire.. thats when it happens.

whats up with that. poping is lean right? it worked good for 4 months --- hmmmmm crab geting soiled??? naw how baout fuel screw needs a 1/4 turn to richen it up??

if so which way adds more fuel. clockwise?

popping is rich, backfiring is lean...adjust the fuel screw as needed..... :cry:

yes it did get colder. i was thinking that. but now Dom has me confused when is a pop not a back fire?? I thought they were the same. if not this is more of a pop. I'll try the screw out 1/4 turn first.


it's a pop. so that is lean. I'll turn the screw out like you said. Still loving the 525 exc? did you raise the bars any? what bout the hayabusa, would you recomend a new one as second bike. the 525 is on the list.... should hayabusa be too?

I'm looking at the husqvarna TE 510. the 05 is dry weight 237! thats amazing.

Oh I turned out my fuel screw today 1/4 turn and the poping is gone. thanks for the tip. Funny little things carburetors are. THe DRZ was rocking my world today!!! had some perfect dirt at a local woods spot to ride in.... that bike is something special. :cry:

      I had a gsx-s750 and got rid of it and picked up a 2015 drz400sm this week. It's used and the last guy put knobbies on it. I'm switching back to Michelin power 2ct. stock tire size is 140/70. The current tires are 150/70. I was looking at running 160/60. Anyone know if this would be a problem? I'm just getting into the supermoto life so any other general suggestions would be great. Thanks!

      I totaled my DRZ400S last year, did a good bit of work to it and finally got it running.. I want to turn this into my full stunt bike.
      I have read before about people buying a 2nd stock rear caliper & bracket - then cutting and welding it to the existing bracket, then just running a handbrake master, and a hose to the 2nd caliper. 
      Has anyone done this before? Defiantly seems to be the cheapest route to go (staying away from the junction valve / 1 master cyl. & 1 caliper setup.)
      Looking for opinions, pros/cons, and info if anyone has gone this route.. If it seems too much of a risk or hassle I guess im gonna have to spend the $500/$600 to get a legitimate setup 
      any and all comments are appreciated - except trolls.. you better be funny as hell if your gonna troll.
      Thank you all!
