Use Yamaha NEEDLE (6BFY42-74) in 2007 CR125R

[BLL]

Hey guys, just picked up a 2007 CR125R that is exhibiting the jetting issues that many folks have with this bike.  Runs great up top but crap down low.  I dropped the main to 410 and pilot to 45 as well as opened up the airbox.  Yesterday was about 70 degrees, it ran very well until I idled it for about 10 seconds and it promptly fouled.  Replaced the BR9 with an 8 and rode the rest of the day.  

 

I've read tons of posts about it and I'd rather avoid paying 70 bucks for what amounts to the JD needle and I also don't plan on going to  Kehin.

 

So I ask:

 

Has anyone used the Yamaha needle NEEDLE (6BFY42-74) and had success?

 

RMC has it in stock while the Honda is back ordered.

 

Thanks

I had a 06 cr125 that I tried one in it was a little flat in the mid.

I should have tried one more clip richer I would put money on that being the reason now but I was not as experience with jetting then and was changing more than one part of the jetting hopping to stumble upon a good setting.

I did find on a forum ( think it was allthingsmoto) where a guy was having issues with jetting on his 05 cr125 and there was a lot of discussion . His final post was fixed it!

Put a yz125 needle in.
