  1. Hi TT'ers! I have a 2008 DR650SE. The bike is completely STOCK but experiencing some stumble off low throttle positioning (like it’s about to stall). Removing the snorkel improved it a little bit. I haven't drilled out the second slide hole yet. Would like to make it run better without spending too much money on an exhaust system. I have read the DynoJet stage 2 kit is for stock exhaust and carb? Looking forward to your reply and many thanks.
  2. Hi All, I have a Yamaha XT250 (similar to XT350) that is a single cyclinder Dual carb. After fitting a highler flowing slip on (reverse cone), I am experiencing some hesitation on WOT. When I pulled the carb apart, I found the following configuration: Pilot Jet: 42 Primary main jet: 118 Primary Needle position 3rd clip position from top. Secondary main jet: 110 Secondary Needle position 3 clip position from top Fuel mix screw 2.5 turns out. I raised the clip on Secondary Carb Needle to the top most, being the most leanest. Took it for a ride and WOT felt a little better. Does that mean I am running too big of a Secondary main jet? At first I thought the splutter at WOT was a result of being too lean but perhaps my Secondary main being too rich? One thing I don't understand though, before I fitted a custom slip on, I never had the splutter at WOT with stock exhaust. I would have thought installing a higher flowing exhaust would make it leaner, but in fact I had to adjust the needle leaner? What do you think is the explanation for this? I'll attach photos of my spark plug. Looking forward to any advice! Thanks in advance Attached Thumbnails

  4. Hi thanks for your reply. I haven't taken apart the carb yet. I've just received a Sigma jet kit with a larger 135 main jet and shims to raise the needle. Will do this tonight and likely be able to test the bike on the weekends and report back (I live in an apartment and neighbours don't take too kindly with my motorcycle when i finish late at work ahah)
  5. looks quite rich. perhaps drill some holes on the air box?
  6. Thank you! I will do that. and sorry i forgot to mention my bike is a XT250 1984 (dual carb YDLS)
  7. Hi guys! I wanted to ask for your advice regarding tuning the carby. Since I had a the reverse cone muffler fitted, i'm experiencing some hesitation and splutter in the high rev range. Would you guys be able to steer me in the right direction of what I could do to tune it correctly? There is a lot of heavy air pressure coming out (is this called back pressure?) I would imagine there is more air flowing out so will i need to raise the needle in the carb? Does this indicate it is running too lean? thanks!
  8. Also, do you think it's possibly the spark plug?
  9. Sounds like it's a green light for adjusting the fuel screw and might as well do the 3x3 mod? Looks like I gotta take out all the carby..
  10. Yeh mate really good people here with no egos in the way Hows your CB400 going?
  11. haha hey Positron funny seeing you here!
  12. Eventually, I will do the 3x3 + Jetting but I am just a little annoyed why a stock DRZ may be experiencing these problems.. Here's hoping a 3x3 and Jetting will cure it!
  13. No rejets on the carb at all. Bike behaves fine when cruising around. Just getting it to start is an issue. Bike idles fine after a few minutes warming up. I am just curious why the bike will die as soon as I pull out the choke without pumping some throttle?
  14. Hi Shift, sorry I forgot to mention specs. Yes, stock DRZ400 with only a FMF Q4 muffler.
