115
& some sort of other jet 35
From what I can gather the ch n needle is probably the n3ch that jakobi said about but there's no number 3 on it.
Looks like I just have to get a 42 pilot

Would be good to see how u get on biff

Biffs on the money mate! The CHN is a big thick bugger thats designed to be used with the corked up engine. It'll be far too lean for anything. Toothpick?

Speedgeeza.. One of those needles Your slide should be fine.

If you want part numbers or anything jst ask.

N3CJ needle installed #3
Will put a few miles on this week to compare with stock needle (when seat bolt arrives)
Last ride equated to 25 mpg- 50miles to reserve

Yep, sorry. I mean't needle. Ordered it this morning along with a 40 and 38 pilot jet just incase. The needle was only $17.
The parts guy needed a bike to look up the needle part number. So I said try an '11 YZ250. Bingo! I think this was the last year they made the two stroke 250??? Parts should arrive in a week.
Thanks for the advice. First race on the bike, a week on Sunday.

I just installed the n3cj setup, wow, sh?t eating grin, you can expect near perfect off idle fuelling, torquey bottom end and an 'interesting' controlled explosion onto the pipe that is absolutely perfect for trail riding or for someone racing that likes to sit just off the pipe in the surge and has good throttle control..well done jake, amazing. I'm ordering the replacement needle and will send all back soon. Cheers

Thats sums it up nicely Simmo. Glad to hear its working in the 2013 models too! Hope it works as well for those overseas.

What is the richest straight dia. that series is available in? Back to back races in the next couple weeks, using my two bikes, rather not share the JD Blue. If Smartcarb ships on time its still a week in UPS, plus install, setup, and test ride time before next race. Mid May at best realistically, so I need a needle thats close.

An N3CF needle is the richest in the N3xx series. It's sold as a KTM needle.

Thanks MJC. I'll try and pick a couple richer ones up at the local dealer this week. I have the entire range of Suzuki needles but they are just too lean off the bottom with the older carb.

They're available in all the standard sizes Glenn (C through to L)

When first researching jetting I recall hobbit? suggesting that N3EG was his recommendation for the older carbs.

I think most of the n3xc-n3xe needles have been discontinued. I only see the n3ce needle as still being offered. The needles go forward n3 C or E starting at F diameter.

I use an n3eg in my honda cr125, and that's with an PWK AS2
