06' Stock Jetting Help!

[Pasi S.]

Yeap! Like I told you this works for me.

The biggest problem is - I think - I speak Finish and think in Finish, then I translate it in my mind to English. If I could speak English better, I think I could spare a few hundred words out of that. LOL!

 

In my motor I couldn´t ask from anyone any starting point, because my porting is made by my own hands, so no one knows what kind of porting it is.

I did all my mods at once, from the bone stock motor to what I have now.

 

First I find out my mains, then clear out my mid-range from needles, and after that I adjust my pilot circuit. That´s it.

If I can do good in mid to top and have a useless low-end or have a good low to mid and have a powerless top-end, I assume my needles are wrong kind.

 

I hope that you will figure yours out and have a good runing bike!

For my sake, I hope I can too. It flat out kicked my ass yesterday. It's a challenge doing this on my own but thankfullly I have guys I can ask for advice. Just know one physically to help me. I thought I was gonna have it yesterday but....not so much. I got pissed off and just let it sit for the rest of the day.

 

Made a couple phone calls and was givin advice to order up a dyna jet jetting kit. It's suppose to be in tuesday so hopefully that will solve my problem. The guy that sold it to me has been working on and tuning banshee's since they debut back in 87. So naturally I took his advice. He explained to me that my problem was basically my stock needles so hopefully this kit will get me where I need to go.

The needles are wierd bro,some bikes need em some dont.I have full drag ported 4 mil on stock needles no probs,but my 06 LE needed vitos needles to run rite,They are a richer needle

I don´t want to mess your head or anything but, if you are going to go with Dyna Jet-jet kit, most of us can´t really help you easily any more because Dyna´s jet numbers are not the same as stock Mikunis.

You are just getting a different set of pilot jets and different needle and a buch of main jets. You can be in a same situation where you are at this moment, but with the different jets.

 

When you are telling us that your whole shit is fucked up. I think the people over here who are trying to help you, need to know what was the jetting/adjustments and the symptoms.

 

IMO Your modifications are not so big that you can´t solve your problems in a traditional way. I think that your engine is running too rich.

 

Can you ride with your Banshee in a jogging speed (1.st gear) and pull the clutch in and it will stay alive with a good idling? ...or will it die? ...or is the idling RPMs higher than normal and comes down slowly?

 

In the needle you usually don´t need to use the 1.st and the 5.th position at all. If that is the must thing to do to get it run right, your needle is not what you need to use.

 

IMHO, your stock port cylinders and your pipes will give you a quite broad and forgiving powerband. If your main jets are "X" for the BEST power, you can´t notice anything big in your power delivery if you change your main jets 2 or 3 size bigger. This will give you -with those 2nd, 3th, and 4th clip in the needle - enough room to make it right. ( I´m not telling you , just saying)

 

If I were you, I would test 27.5 pilot 1.5, needle in 3rd. and 270 mains. Do that "pilot/air-screw-test" like I told you and IF you need to adjust it up to 2.5 or more, go back to 25 pilot.

Then make a plug chop-test to se how is your main jets. They can´t be far off. After that ride it and see how is the mid-range. If there is powerless hesitation, give it a little more gas from going up from the needle. If it´s too much, go back, and put one size bigger main, and try it again. Going one up in a main won´t take too much out of your topend power, but it might be just enough to save your mid-range.

 

Good luck! ..and sorry my bad english.

your english isn't very bad Pasi I follow ya. I'm not so much worried about gaining a shit load of horsepower by adjusting my mains or anything. I just was the bitch run right! I have literally been jackin with this thing for 2 weeks now! trying to get it right. Maybe the dyna jet is a good idea? Maybe it isn't? but I have to try somthing because nothing I'm doing is working. I'm trying to make it out to the sand by this coming sat so we'll see....

That's what this guy was trying to explain to me. This was the first time doing buisness with these people and I belive the guy I was talknig too was the owner/operator. I told him what year I had, plus my mods and he stopped me mid sentence after I told him and said " it's the stock needles". He then proceded to explain why.

[sleeper06]

The reasoning being the stock needles re only good to a 280 main,I was told that once

I'm gonna get her. That Jet kit is suppose to be here tomm. I had one more idea to try but I didn't jack with it today. I'll hit her up tommorow. I believe by then my anger will have calmed. Do you know any more information on the needle subject? I find that kinda interesting and didn't know that the stokers were only good until 280.\

 

Sandtrax out of Tulsa Ok. is who i'm doing buisness with. My good family friend that I have known ever since I was a little kid is sponsored through them and has been for the past 10yrs or so.

I´m still quite sure that your emgine is running rich. Test the Dyna Jet-kit and see how it´s going to be. I just hope that you will solve it out. I know those fealings having the jetting a way off.

 

 

Read this topic.. You can find there a similar set ups like yours, to get something to test.

Most of the people running over 300 mains seems to have a port job done.

Well......Parts didn't show today. Go figure?? So in the mean time, trying to not to waste another day I tried my last and final move until the dynajet kit shows up. I put it bike back to exactly what it had in it when I bought it. 320 main, 25 pilot, Needle 3rd position (middle clip). Close.. but no cigar.

 

So now with rain threatning my tuning sessions after I get off work tomm. and my bike needing to be tuned and ready to rock by friday morning. Chances are I'm just going to have to miss this race and wait until next month to go raise hell. I'm not gonna lie it's frustrating not getting in tune yet but I love a challenge. This just became personal!! lol
