  1. Hey All, I have a question about needle taper and how it affects fueling? 2003 DRZ400S (E model FCR39, 3x3, E Header with fiber wrap, Stock S muffler with endcap mod, and stock S cams). JD JEtting stage 2 Kit for DRZ E model, not for the S model with FCR Current Carb Settings: -155 main -Blue needle 2nd clip from top (DRZ E taper profile) -Coast enrichener removed -everything else stock E Carb settings (including slow jets, and air jets) -idle screw = 2 1/8 turns out (and idles perfect) I ordered the EMN needle as per suggestions from other TTers My Question: I was just wondering what the EMN needle would do to my AFR graph? The taper chart doesn't make sense to me. If you see the attached image, my AFR seems to be rich at 1/4 and 4/4. I believe the EMN needle will flatten/richen out my mid range. So, to compensate I also bought a 150 main. Is this a correct assumption? PS. Is the first rich state the AP effects? I know it's too rich because it's not a punchy as a pumper should be. I'm saving up for a leak jet kit/power bowl/AP cover, but was just wonder what effects to look for when I start tuning more in the next few months as funds become available? Thanks! Note: Blue is first run with needle clip in 4th from top. Red is 5th run with needle 2nd from top to lean it out. Note:
  2. Just tightened my valve lash to spec after having terrible clacking noise when idling. It would start before when cold with no choke at all but would click and clack when idling. But now, with the correct valve adjustment, the engine does not want to start. It will backfire and damn near break my foot so I know that it is definitely getting fuel. What is the best way to adjust the carburetors on these bikes? I know there is the large screw on the right side to adjust both of the slides for idle speed, but where is the air-fuel mixture screw on the carbs? I suspect this is my issue now that the valve lash is adjusted correctly. Any info or advice would be greatly appreciated.
  3. As I get my 2017 300xcw jetting sorted out I got my first estimate on fuel mileage. At a B pace in the woods I'm getting roughly 30 to 35 mpg. With the stock 2.5gal tank that should be good for about 75 miles. This is somewhat limiting in range. I am considering a IMS 3.2 gal (~95+ mile range) and Acerbis 3.0 gal (~90+ mile range) Who has put one of these tanks on their 2017 or 2018 smoker? How was fit and ergonomics?
  4. I know this topic has been discussed in the past, but I have not found any options available for the new 2018 bikes. I live and work for a new Beta Dealer (Auburn Extreme Powersports) in California, and we are having a difficult time mapping the RR-S bikes for full FMF exhausts. We have tried contacting Beta Support several times for this issue to no avail, and we typically are given the runaround when transferring to techs and secretaries. From what we can gather, the FMF flash is designed for the RR bikes, but not the street-legal counterparts. Every time we try to install the FMF map onto an RR-S errors occur, and the programmer screen goes virtually blank. We have heard through the grapevine that some are using the RR maps on the RR-S with success, but we have yet to try it, even on our own bikes for fear that it will permanently erase or damage the CDI. Any and all help or suggestions regarding this topic would surely be appreciated! Thanks, Ben.
  5. Please help! I recently bought a Yz250f and have not been able to start it, it Has spark, but there are many issues with the carby which I wanna rule out before I leap into a rebuild, ( I want to avoid a rebuild if possible as I’m low on cash). The carby at the moment is a complete mess so the usual steps to fixing it might not work. So here’s the deal with the carb: - It’s leaking fuel from overflow ( really fast! ) and when I mean really fast, I mean it emptied my fuel tank in 2 mins. - It has a slow leak coming from somewhere under the float bowl - the air fuel screw is not adjusted correctly - I don’t know if the electrics work on it either - I don’t even know if it’s shooting fuel into the cylinder or not, as after kicking it a couple times and it’s not starting I remove the spark plug and it’s still dry. ( I tried putting fuel directly into cylinder from the spark plug hole but the bike still wouldn’t start) okay so I know it’s a lot but I’m not expecting anyone to answer every single question themselves. If each person could tackle whatever problem they know it would help heaps. Also just want to know what Order to fix things in as I can’t do air fuel until the bike is running and it won’t run unless I stop the leaking and get it to spray fuel into the cylinder. And buying a new carby is not an option ( I’ve got $40 to my name atm). Please help guys thanks.
  6. Not that many things on here regarding fuel and the Yz125 specifically. Locally, I can only get 91 octane ethanol gas, which is not what the manual calls for. It calls for 93 or higher......I have two other options each about 20 miles away....one is 93 octane ethanol gas from the pump, or go to sunoco and get 110 octane ethanol free......Any thoughts? Keep in mind, my engine is stock, and I don't plan to mod it out a whole lot in the near future. Any harm to running the 110 gas?
  7. Hey all, i'm from Australia and i've been putting 98 Premium into my bike but its going off pretty quick and im only getting 120ishKM per tank and i was wondering if i put a different kind of fuel in my bike would i get more KM per tank? thanks
  8. Hi I recently bought a KTM 250sx 2005 and my bike leaks a lot of oil. I made a topic recently asking how to fix this and got amazing answers from everyone! And I asked this question on the other topic, yet to be answered, but I felt it was a different question wholly due to the paragraph it took to ask the question. And if it is answered there, this one can be deleted, but I wanted to know how do I tune the carburetor to run 50:1. It currently runs 32:1 and I believe the carb is tuned for that. I don't know jet specs but I will try to find out. I know you can adjust the jets via the air/fuel screw... I was told to turn it all the way lean and run the fuel, and I understand to adjust accordingly. But I just want to know what I must do to know if I should turn it richer or leaner based on what the bike does. What are the signs to tell to tune richer once I turn it all the way lean? And is there only one screw I must turn? or are there many? someone please explain all of this.
  9. I was wondering if you can run 91 Octane fuel in a 2018 250/300 XC. I see in the manual it shows 98 or 95 octane and the oil mix changes with each. Is it safe to use 91 Octane ? If so what is the best oil mix to use ? And will it effect performance ?
  10. Hi all, I have a 2004 honda crf250r and it wont start hot at all. The motor was just rebuilt with a new cylinder and piston. The valves were just adjusted. It will start cold in 1 or 2 kicks with choke but as soon as it gets hot it wont start. If you bump start it the motor will just turn over without starting. sometimes it will start. It runs great until you shut it off. im thinking its either a fuel issue or an electrical issue. Any help would be greatly appreciated.
  11. Bike was sitting for a winter before I bought it from my mom. She was the second owner. Was leaking fuel from around petcock, replaced it. Bike now wont idle unless choke is on. It also won't say up to speed upon riding. Took full carb apart and cleaned it. My dad is saying simple float kit for the carb, he says the float is getting stuck and it's dying for fuel. Someone else (the car mechanic that I work with that has worked on his own bike) says it sounds like a accelerator pump. Opinions?
  12. Buckle in this is a long one. Any advice is appreciated! I have a 2011 RMZ 250 that has done me very well for 4 years. Has been a very reliable bike with lots of power. Last year it started to act up a bit, slightly less power & became more difficult to start, especially cold (side note: it’s a Suzuki so it’s never started great cold but usually 3 or 4th kick was the case). Still ran okay though & fiddled with the fuel screw a bit which seemed to help with the starting/power issue for the rest of the season. This past winter we pulled it apart, put a brand new piston in, checked the valve clearances, moderate amount of carbon build up on the valves which we cleaned off, and put in a new spark plug which is also in spec. Bike still wouldn’t start great cold but was starting on about the 8-10th kick and power seemed to be improved although not 100%. I’ve take it for quite a few rides now and broken the new piston in and am having more issues: -won’t kick over cold at all but bump starts just fine -will kick over first or 2nd kick when warm but NOT when the bike starts to get even slightly hot -very little top end power. Bottom of the gears seem to be full power and the hotter the bike gets the less power I have in the top end -bike began to backfire quiet a bit when hot -won’t idle in gear when hot Any advice on what to replace/trouble shoot next? I had a buddy tell me it could be a worn out injector so that’s what I’m looking at replacing next. Thanks!
  13. Hello all, just picked up an 07 cr250r! I plan on keeping this bike nice, and only taking it out a few times since I still have the 450. What’s the best fuel for them CR’s? I’ve heard people talking about detonation from pump gas and that I need 110? Is this true? I’m no racer, just looking for the best for the bike. Thanks!
  14. I have a 2019 Kx100, completely stock. I am looking to put an Fmf fatty expansion chamber as well as an fmf shorty silencer. Stock from the factory, the Kx100s come slightly rich, which is true on my bike. Spark plugs are black, and I have fouled one already. I am waiting to put the pipe on to mess with jetting, but the real question is that if my bike is rich already, and I add a new chamber and silencer, would that possibly make the bike leaner, or would I still have to go down in jets or needle clip? If so, recommendations on what jets or needles I should change to? All jets are stock, with stock NAPF needle. Thanks
  15. Carb only leaks fuel when bike is running out of the overflow tube inside the carb, which causes the fuel to leak out the bottom of the tube because that is where the tube leads to. The bike does not leak with the fuel on and the bike not running. this means the float is not the problem. Could it be the petcock? Drain screw shouldn't be the problem because if it was the fuel would leak all the time.
  16. Hey Guys, I finally updated my old 2012 rmz with a run out new 17. I managed 430 ish hours on the old girl with 3 rebuilds no real dramas. Problem is the new 17 is already giving me the shits that something is not right with it. The very first time I started it it smoked alot, I mean alot. Its my 5th brand new rmz and none have smoked like this. Then with the first oil change post run in there was alot of mater on both the oil filter and screen. Second oil change was after a xc race and trail ride both in the same weekend, 5 hours. That oil smelt like petrol. and it seemed noisy. Then this weekend I went to do the acerbis 4 hour, was going good too 3 hours in and the thing got real noisy I had to pull out sounds like its going to blow up. Thing is it goes like a cut cat. Anyone had issues from new?
  17. Hi, I jetted my bike today and decided to open up the cable area to lube it up. Not sure when exactly it happened but after I opened it up, sprayed some cleaner in there, then lubed it up the cable started sticking. The only other thing I did was put on the lock nut for the cable on the left side in this photo (it was completely off). Now the throttle just sticks open wherever I turn it too. It seems like it is not being pulled back into position not really like it is dirty and sticking because of dirt. It looks clean where I can see, it has been lubed everywhere, and I had no throttle issue before now. Any ideas? kx250f thanks!
  18. Hey all, so my bike is dying when i give it anything over 1/2 throttle. It is completely stock and I have pulled the carb and cleaned the 3 jets. Not very experienced with bikes so any help would be much appreciated. It was running rough when i pulled the carb now it idles perfect but bogs down under throttle. I have changed the plug and have tried running with no air filter. I also took the carb off again to make sure float wasn't stuck. Here is a clip of the bike https://drive.google.com/open?id=0B6FW4yt2Oja3Wks5NDNGNXBiUjA
  19. Good evening tt! New guy here! I have an 01 yz125 i fully restored and rebuilt from ground up. However i am now hitting an issue with the bike where it is breaking up half throttle, seemingly right before powerband. This occurs on or of choke too.The bike is all stock aside from New top end and bottom end and seals, which are all stock spec. My carburetor and jetting all checks out. My reeds are good. It has a brand new plug and new fuel. The bike has been set up like this for almost 2 years and has been running great until last week. Im thinking it may be ignition related but would appreciate any second opinions. Thank you!
  20. I'm new to this form and have a couple of my bikes I have questions on. First bike is my 2003 KTM 450 SX. It runs great and I can run it down the road throttle and on trails no problem without it dying on me. But when I jump it, it spits, sputters and dies. So when I land I need to pop the clutch to get it started again. Any idea what this could be? second question is on my 2003 KTM 125 sx. When I'm riding it it tends to surge around 3/4 to full throttle. But when I let off it will kinda go back to normal. I've cleaned the carb, new air cleaner, fresh rebuild, just can't figure it out. any help would be appreciated. I am a marine mechanic so I usually can figure this kind of stuff out but I've been stuck on these two bikes for awhile. Thanks
  21. Just serviced my 2015 YZ250F, noticed the oil looked thinner than normal, and on closer inspection found oil smelt of fuel. Being fuel injected how can this happen? Leaking injector? Anyone had the same problem?
  22. Is it alright to run Turbo Blue 110 octane in my 125 or should i mix it with reg? along with Amsoil Dominator of course
  23. So picked up this 00’ rm 125 yesterday and bike is overall pretty decent. Definitely needs reeds. Pulled everything off to check them, but, got down to the reed valve (still installed) and it is stuck onto the motor. Looks like theirs even some liquid gasket on it. Any ideas on getting this thing off? Or am I looking over something?
  24. I had my CRF250r rebuilt back in may and it hasn’t been ridden since. I decided I might as well sell it so I wanted to make sure it was running and nothing. I drained the gas, put new gas in it, cleaned the carb, and still I can’t get it to kick start. It’ll bump start but it won’t idle, it’ll only stay running if I give it constant low rpm revs and if I go too high or too low it’ll stall out and die. I’ve done all that I can think to do so I’m coming here hoping I might be put on the right path of getting it fixed
  25. I have a 2008 YZ450F with a stock header pipe and Pro Circuit T-4 Slip-On Exhaust. I'm 99% sure the slip on is shot because its loud as hell and when I take it off and shake it it rattles. I would repack it but the screws are all stripped ect. Anyways I've gone over the carb multiple times and I've got it running pretty well. The only issue I have with the bike is that it sputters and pops around 1/2 throttle when I hold it there. When I give it full throttle from any RPM it runs great or when I give it about 3/4 throttle it spins up like a top to redline. Initially the popping and sputtering was way worse I made the situation better by moving the pilot jet up in a few sizes from a 45 (stock) to a 62. The issue has gotten way better since then but I'm not super sure what to do from here. Should I keep moving my pilot jet up in size because that's a pretty large jump right? I tried changing my needle clip position but that didn't help much if anything it just made starting it worse and little to no impact on the ride. Any input on this would be helpful. I don't want to buy other slip on. Also as for the rest of the carb I'm very sure everything else in it is what it needs to be at. I've replaced all the gaskets and O-rings cleaned all the jets, valve holes ect. fixed the accelerator pump timing. I just thinks its strange that my pilot jet size is going so far from the stock 45, but all symptoms point to the bike running lean.
