  1. all modern mx bikes have leaking fork seals when the mud dries out and goes hard
  2. with all due respect it sounds like you are very new to drz's and carburetors in general, i would hold off on any purchases until you have spent some time learning and researching,i know labor costs in australia are high so sometimes it works out better just buying a new item but for most drz owners we get alot of satisfaction on learning about what we have and doing the work ourselves
  3. i went through the motarding process on my wr450 using the cbr250rr wheels, i know its not a drz400 but the process is the same i got all my spacers and adapters made here in thailand as labour costs in australia are ridiculously expensive. i got a disc adpater made up and used a factory gsxr100 brake rotor which is 310mm . if you need anything made up let me know and i could ship it to you
  4. thats a very difficult question to answer as it doesn't take into account temperature and humidity,i understand what you are saying about overly rich jetting guides as you get closer to the equator things start changing. i would go to a shop with a gas analyser and get some base AFR's for your bike,then you can determine how rich it is running. if it is running rich now do use E10 91 gasohol,this gives the leanest burn. do you already have the airbox cut to 3x3? if its any help i live in northern thailand which is hot and humid,i run a 145 main jet,dxp needle clip 2 and 45 pilot jet
  5. yes looks like the wrong lines,carbs don't usually have black overflow lines
  6. cheers guys. think i will pull out the emulsion tube/jet needle and check that as suggested, as far as i can see there really itsn't much leaner in needles than a dxp so there must be something else at fault
  7. 3x3 opening. pilot air is a 105 main air is 200. yes second clip from the top. i thought D was leaner than E but thats why i asked for advice as my knowledge on needles is not great. could you confirm by looking at the needle chart,maybe i am reading it wrong. EMP was unusable at 1/8th with AFR's in the mid 15's. i thought 12.6 was a good number for E10 given maximum power is at 12.2 ? i was wondering why on thumpertalk is the pilot air jet always stated as #100. this is a variable jet like any other and i've noticed other websites from other bikes play with this jet. i tried a 42 pilot jet but was loo lean,45 seems too rich so would it be worth trying a 42 pilot with a 75 pilot air jet. carb is slant FCR from a wr400. float level is set at 9mm but good point on the worn needle jet, i forgot to check that my AFR's are usually taken at about 3000ft, temps at around 35 celsius, humidity is usually high around 80 percent although thats not the case now as its winter here in thailand
  8. i'm in northern thailand.
  9. not sure if this is the right place to post but thought i would ask the question as there is so little information about this on the internet. i have bought a kdx220 and the jetting is way off. there is no information on the internet for jetting this close to the equator so decided to weld a bung in the pipe to try my wideband o2 sensor. does anybody have any experience with doing this and what kind of AFR's should i be tuning for,is it the same 12.7 as a 4 stroke
  10. anything EM is too rich. already tried EMN and EMP
  11. after 5 years of trying to get this dam slant FCR tuned i am close but still not close enough. jetting is as follows fuel screw 2 turns out, 45 pilot jet, dxp needle clip 2 with the straight diameter slightly sanded down, 148 main jet coast enrichener removed and ports plugged AFR's are as follows idle-12.6 1/8th-11.3 1/4-11.0 1/2-11.7 3/4-11.5 WOT-12.6 the bike has various small stutters throughout the rev range as you can imagine, at about 1/16th the bike jumps into the high 13's and almost stalls, the reason i sanded down the dxp needle is it would stall at 1/16th as it moved into the 14's. i have 2 needles that i can try ,they are - OBDVN and OBDTM, both are yamaha needles from memory. any suggestions which one to use and what clip position, the problem with it almost stalling at 1/16th has me thinking to put the coast enrichener back on. i run the bike on E10 91RON. if i switch to any fuel with a higher octane it runs horribly rich,i know maximum power on E10 is 12.2 but happy to run slightly leaner as it is winter here
  12. correct. import products are subject to 20-100 percent tax. thailand has a free trade deal agreement as far as i know with china so no tax.
  13. my bikemaster battery finally stopped working after 5 years and i am now struggling to source a battery for my drz400sm. here in northern thailand the local motobatt dealer was my only chance,he had 5 drz batteries all 3 years old. i tried 1 and it lasted a couple of starts,tried another and it only lasted a couple of starts lead acid batteries aren't generally shipped international and lithium shipped to thailand is well out of my price range. whats the smallest battery i can run? there are a couple of 7ah batteries available here but all much taller,has anybody tried cutting the bottom out of the battery box? i know there is an oversize battery bracket available in the USA but again by the time i buy it,ship it here pay the import taxes then buy the bigger battery i will be a fair bit poorer. has anybody tried these lithium batteries available from china,i know the terminals are opposite but should be an easy fix https://www.aliexpress.com/item/12V-HJB7L-FPS-high-quality-lifepo4-motorcycle-jump-starter-lithium-ion-battery-with-BMS-and-more/32805176082.html?spm=2114.search0104.3.50.lzl3Qv&ws_ab_test=searchweb0_0,searchweb201602_1_5130011_10152_10065_10151_10344_10068_10345_10342_10343_51102_10340_10341_10609_5000011_10541_10084_10083_10307_10610_5080011_10539_10312_10059_10313_10314_10534_100031_10604_10603_10103_10605_10594_5060011_10142_10107,searchweb201603_25,ppcSwitch_2&algo_expid=b56953f2-00de-44f0-9962-8bc5257a03eb-6&algo_pvid=b56953f2-00de-44f0-9962-8bc5257a03eb&rmStoreLevelAB=0
