Bike worked great today. Didn't have to touch a thing. No burble and pulled nice and clean to the top. Had that nice zingy 250 feel. Checked the plug (new) and it was starting to brown up just nice. No spooge. Much easier to loft the front wheel over stuff now.

I rode with 45 N3CJ#3 178. I pretty much disregard main for the most as its the last circuit I dial in. In saying that it went well up top. It went well in the middle too. And sputtered and burbled off idle. Coming out on the AS saw the idle speed lift so I must have ended up around 3.5 turns out and still burbling so tomorrow I will run 42 N3EJ#2 178. I had thought about jumping the full clip postion, but decided I'll take it step by step so I can accurately judge one from the other. Even with the jetting a bit richer than the 300 the 250 had much more zing about it when getting into it.

Did a few test runs including a short stint with 42 N3EJ#1 178. No hesitation or bogging but the magic spot for me has been N3CJ#3. Half a clip richer and the burble on the needle starts, half a clip leaner and the bike runs like a raped ape once on the second taper, but is a tad weaker on the first. I suspect I will lean the main out a size or two possibly to give the top end some more over rev. The rest is unreal! Fanastic torque right off idle, into the mid and then explodes to life! So stoked.

After a few longer and challenging rides I've come to discover a few things. The J diameter doesn't give enough grunt off the bottom. Its too lean and lacks balls. The same way N3Ex#2 is too lean and makes the needle weak. Going up from a 42 pilot with the J the bike starts to develop an irritating burble that doesn't clear up as soon as throttle is give - It lasts more towards 1/4 throttle.
I then gave 42 N3EW#2 178 a run. Too rich on the pilot. Expect 40/W to be the magic combo, but too lean on clip 2. Lacks lugging power with the throttle open on the needle. Went to 38 N3CH#3 178. The pilot is too lean as it has to almost be right in to give best response. Going richer on the pilot might help out but I think I might run into the extra burbles into the throttle. I'll have to test it. Even with the PJ lean the richer needle diameter gives a significant boost to bottom end torque. The bike will easily chugg a few gears higher. I think I need to get a N3CW to pair up with the 40 pilot. It should give the best of both worlds. Going another half a clip richer uses more fuel and doesnt give any benefits. Starts to feel too rich on the bottom and particularly into the mid/top |

have you tried a different slide? My brother had to change his slide on his last 250.

Running a #7 non notched slide. It should be fine for the 250 and others here have had them work well with the W diameter needle. I ordered a N3CW tonight which I expect will give me the in between N3CJ and N3CH which will be just right. The N3CJ is very close to perfect with a 42 pilot. The N3CW with a 40 will just give it a little more grunt off the bottom end.
I also decided to spend a few extra coins to do some testing. Ordered 2 x Kawi needles. N3WW which might go alright in clip #2, and a NALW which I honestly expect to be pig rich. I had considered a NFTW but decided not. There is very little info on the kawi needles around. I might try the Suzi needles again at some point too. What slide did your brother end up running? |

#8, and the bike worked awesome. I have no idea what the rest of his set up was. Will try and find out.

He broke out a 2012 250 race yesterday so he will be getting into the jetting too. What a different animal that is. Feels nothing like my 2011. I would say it fits me much better though at 6 feet.

Is there a chart some where for slides. I have a number 8 here to try if need be.
