G’day, very,very new to this, however this site is BRILLIANT!. I live in southwest Victoria and are currently doing up a 96 xr 600 to do an outback trip ( been working on the bike for 2 years $$$$$$$$$ !!!) anyway after being F###D around by spanners the xr is almost ready almost. The info on TM 38 jetting was extremly helpfull but what is the best suited jetting. I have 1mm over size piston less than 1 km old and a BRAND NEW mikuni tm 38 carby I was told to run a 12.5 needle jet and a 230 main jet I would love to know what the pilot jet is but I can’t get the float pin out.The reason I got the mikuni is I was sick of the flat spot/sticky throttle on the oem carby. Now I still have the same problem and IF! I do get it started ( which I have after hours & hours of kicking) it back fires blows a little black smoke,what appears to look like steam constantly coming from the pipe (stock) & then when I twist the throttle ( still sticks ) it either stalls or farts & pops away.This bike has cost me almost 2 new dr 650’s (this includes the gear to do the trip,I bought the xr as I am on less than a shoe string budget & now more broke than Italy ) I phoned Ballards this morning in hoping they could & they said that I needed a different slide & needle I could buy the needle but not the slide? The curent needle is a 6fj40. I did not get the carby from Ballards.They also said that without the slide it was pointless getting “there” needle so I bought a 210 & a 220 main jet,they should be here Wed. I am ropable at this point any HELP would be GR8tly appreciated cheers F###N bike
