Kleinki Posted January 16, 2016 Report Share Posted January 16, 2016 Hi guys. Ive got a stock banshee with dmc pipes and proflow air filter. I do enduro racing in south africa so its all terrain. I would just like to know if anyone has run a keihin 38mm setup. Like always there is loads of guys saying yes it will be fine and loads saying no 35mm is biggest it can handle. Reason im going for this setup is obvious the one carb tune and smoother throttle. The setup will be Chariot 2:1, vforce4, 38mm pwk.

trickedcarbine Posted January 16, 2016 Report Share Posted January 16, 2016 If you do go after the 2/1 intake, use a 39mm PWK. Look in to the EEK needle. And look for a Graydon intake or a stock early 440 yamaha exciter snowmobile intake. Quote Link to comment Share on other sites More sharing options...
Kleinki Posted January 17, 2016 Author Report Share Posted January 17, 2016 See the chariot is already in the post ... I do not wane port engine.. Wane try and keep standard for as long as possible. Would it be okey with the 38mm if tuned correctly. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted January 17, 2016 Report Share Posted January 17, 2016 Why not just avoid all the headache and just jet your stock carbs? Once you dial them in, you don't have to do much if anything to them at all. I suggest that, because it's easy to get those dialed in. The 2/1 is quite finicky and can be a bit of a challenge. IMO, the single will require more tuning ability then the dual stockers. Quote Link to comment Share on other sites More sharing options...
Kleinki Posted January 17, 2016 Author Report Share Posted January 17, 2016 I hear what you saying like i said it would help me with my racing. I just wane know if the 38mm would work fine if dialled in correctly. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted January 17, 2016 Report Share Posted January 17, 2016 Yes, if you must. The 38 would be far better then a 35 IMO. Quote Link to comment Share on other sites More sharing options...
Kleinki Posted January 17, 2016 Author Report Share Posted January 17, 2016 Thanks for that. And any start point regarding needle and jetting. 6000ft and is between 25-35c temperature. I would take a guess.. Main 180... Pilot 55.. EEK needle middle clip.. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

Kleinki Posted January 17, 2016 Author Report Share Posted January 17, 2016 Any part number for this EEK needle please... Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Kleinki Posted January 17, 2016 Author Report Share Posted January 17, 2016 Doing some reeding regarding the EK needle its the leanest needle for yamaha if im not mistaken... Would the yz 250/ktm 300 jd jetting kit work at all as the needle is leaned out more through the throttle.

You will be asking for info on a not so common set up so info will be kinda sparse. We can probably get you close, but you'll definitely be fiddling with it. Some one posted a factory bike needle for 2/1 set ups just recently, so maybe track that down. With the stock carbs, I would bet guys here could have you dialed in within one afternoon of tuning. The 2/1 isn't gonna turn that thing in to a stump pulling machine that you're hoping. Can I ask why you feel the 2/1 is the golden ticket and what you hope to get out of it?

Kleinki Posted January 17, 2016 Author Report Share Posted January 17, 2016 I can tune the dual carbs and have done before. Im not doing the change just because its one carb. Ive read good things about the 2:1 one and there is tons of banshees and snowmobiles that run single carbs. The change is not gone be a 10-20hp difference. The reason why im changing is it will be much easier for me with the racing i do. Im not after extra hp or anything like that. If i can get a easier way to make things easier for me i will go for it. I just thought that i might get some good replies about what carb, needle and jetting worked for guys but guess no one can just give me a straight answer.

trickedcarbine Posted January 17, 2016 Report Share Posted January 17, 2016 It's just not something that is common. So getting a straight answer will be near impossible. That's why I say it's more of a hassle. The theory is that come race day, a simple single carb would be easier to change. But with a non existent base of knowledge you'll be hard up to know where to start. Which turns in to lots of fiddling and tweaking that the single carb was supposed to avoid all along. You can try and compare your set up to what's out there, but if you change one aspect, it will be all unknown again. Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted January 17, 2016 Report Share Posted January 17, 2016 Awhile ago one guy (snop) did a bunch of test between a single carb vs dual carbs. He was a huge single carb fan until he actually did a bunch of dyno testing with the two setups. After the testing he said that dual carbs maybe better power every where through the dyno curve.
