WOW! What Happened?!?!

I was riding today and my bike was feeling a bit boggy, I though it was just that the bike was not warmed up yet. After about 5-10 minutes of cruising around the biek was still bogging out badly and smoking a ton. It was going just fine when i would pin it but it felt horrible 1/2-3/4 throttle. So when I get home i pull the carb apart. Everything looked fine until I came across the needle. The clip that was in the top position was now in the bottem position and the clip was REALLY bent.:thumbsup: What could have caused this?? Also I am going to get a new needle and clip tomarrow and was wondering what is the best needle to get, it had a N3CJ needle in it, I have no clue about the different types of needles so if anyone has it advice it would help me out a lot.

2002 yz250

168 main

45 pilot

5000-6000 feet

50-60 degrees

40:1 ratio



come on now 30 minutes is a little quick to be bumping your own thread.

the needle will wear where the clip sits over time.not uncommon.

K thanks Eddie, sorry about the bumping hahaha. Does anyone know if there is a better needle I could put in or should i just keep the N3CJ?

Stay with stock unless you have a complete understanding of why not. BTW its likly that it was running richer than stock do to wear on the needle and the needle jet likly has equal wear. I would replace both

ok thanks dave, do you know what the stock needle in the yz250 is ?

      Hi Guys,
      So I recently bought a 1997 XR400. I've done some research into getting more power through some basic mods and rejetting the carbs. Though all of the ones I've found have been for post 98 XR400s so the stock carb set up is a lot different. Usually people are opening up the airbox, exhaust ect. ect. and Jetting their carbs up to 160/162 for mains around 60 ish (I think) for the pilot. However for the 97 model this is close to stock for the jets.
      So essentially what Im asking (Just to cut to the chase ) Has anyone got a 96/97 (maybe 98, not sure) XR400 and has done these similar mods, and what sort of jetting have to done as a result.
      Thanks in advanced, also its my first post so apologies if I havent done everything correctly.

      38MM Cast SmartCarb. Purchased a couple years ago for a yz250. Don't have the bike anymore, and it has been sitting around for about a year. Used, but in fine working condition. You can also purchase a different needle for different bikes, as well as rebuild kits from their website.
      Asking $250 shipped to continental United States. I can arrange other shipping options at the buyers expense.

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      I know this topic has been discussed in the past, but I have not found any options available for the new 2018 bikes. I live and work for a new Beta Dealer (Auburn Extreme Powersports) in California, and we are having a difficult time mapping the RR-S bikes for full FMF exhausts. We have tried contacting Beta Support several times for this issue to no avail, and we typically are given the runaround when transferring to techs and secretaries. From what we can gather, the FMF flash is designed for the RR bikes, but not the street-legal counterparts. Every time we try to install the FMF map onto an RR-S errors occur, and the programmer screen goes virtually blank. We have heard through the grapevine that some are using the RR maps on the RR-S with success, but we have yet to try it, even on our own bikes for fear that it will permanently erase or damage the CDI. Any and all help or suggestions regarding this topic would surely be appreciated! Thanks, Ben.
